===================================
General Information
===================================

Like most VNs, the routes are actually quite easy to get and you shouldn't really need any help. Just pick all the choices that involve being nice to or spending time with the target heroine, and that's it. In particular, always follow them whenever they go somewhere if given the choice (no matter how stalker-y it feels). If for some reason you do need help, the "Routes: Walkthrough" section lists what I think are the important choices for each route (and documents how to get all the bad ends).

However, unlike most VNs, Rewrite has "Mappie segments", and long lists of Friends, Monsters and Quests (each of which is a tab in the Memory menu) that you can encounter or complete as you play. The Monsters list is the shortest, and will be completed no matter what by the time you finish reading the VN, so it is completely ignored in this walkthrough.

Once you get a Friend or Quest, it remains "unlocked" in the Memory section forever. The real difficulty is that some quests, especially Quest 28: "Proof of Paranormal Phenomena", have other quests as prerequisites, in which case you might have to do all the prerequisites in a single playthrough in order to complete the bigger quest, even if you've done those prerequisites in past playthroughs.

It is impossible to get all the Friends and Quests on a single playthrough, and very hard to get all of them on your own without any sort of guidance. The "Friends and Quests: Walkthrough" section describes what I think is the most efficient way to go about getting literally every single friend and quest. The vast majority of you will be most interested in this section.

By the way, even if you're not a completionist, you should still care about getting all the Friends and Quests for three reasons: 1) almost all of the text you end up reading during the process of getting them is just as hilarious as anything else in the common route, and 2) the common route has a handful of nice bonus scenes that get unlocked after completing the game, and 3) you need to complete all quests--and one quest requires getting 100 friends--in order to reach the Oppai Ending. Trust me, you want to read this ending.

Below that are "Friends: List" and "Quests: List" sections, which simply list how to obtain each individual friend or quest. If you managed to complete almost everything on your own and are just missing a handful of things, you'll want to look at these.

===================================
Routes: Walkthrough
===================================

As far as I can tell, absolutely nothing in the Mappie segments influences which of the five heroine routes you end up on (if any), not even the parts where one of the heroines accompanies you. So they're ignored in this section.

I don't try to list every single choice you should make for each route, because a lot of them probably don't matter. Instead I try to list only the important choices, the ones I think are enough to guarantee you get the route no matter what else you do.

I'll also point out bad ends, since why not.

Kotori:
10/3: Something She Likes
10/4: Eat With Kotori
10/6: It Doesn't Matter (to avoid Chihaya route)
10/7: I Can't Answer That
10/16: Follow Kotori
10/18: It's Not a Big Deal (to avoid Lucia route)
10/21: Take This Opportunity to Sleep (to avoid Lucia route)
10/23: Follow Her
10/25: Follow Kotori (choose Go Solo and Look for Chihaya instead to get a bad end on 10/31).

During Kotori's Route:
Only one choice, and it has only one option.

Chihaya:
10/5: Help Her Out
10/6: Follow Her, Save Her
10/7: I Can't Answer That, Braking
10/18: It's Not a Big Deal (to avoid Lucia route)
10/20: I Don't Like His Attitude, But I Want to See the Cat
10/21: Take This Opportunity to Sleep (to avoid Lucia route)
10/23: Watch Her Leave (to avoid Kotori route)
10/25: Go Solo and Look for Chihaya
11/3: I Don't Know
11/12: Save Chihaya

During Chihaya's Route:
Three choices, each with two options. For each choice, one option leads to an immediate bad end. The bad end options are "Dodge It", "Attack Tenma Directly" and "Strengthen Myself Anyway".

Lucia:
10/6: It Doesn't Matter (to avoid Chihaya route)
10/7: I Can't Answer That
10/9: The Classroom's Fine
10/16: Go to the Cafeteria
10/18: I Wanna Know...
10/21: Collaborate with Yoshino
10/23: I Have to Do Something

During Lucia's Route:
No choices.

Shizuru:
Unlock this route by completing Kotori's route.
10/6: It Doesn't Matter (to avoid Chihaya route)
10/7: Myself
10/18: Talk to Her, It's Not a Big Deal (to avoid Lucia route)
10/20: Go
10/21: Take This Opportunity to Sleep (to avoid Lucia route)
10/23: Watch Her Leave (to avoid Kotori route)
10/25: Go Check on Shizuru

If you want to get a lot of Friends and Quests done on your initial playthrough, consider following the instructions from "Playthrough 3" (in the next section). The only thing in there you won't be able to do is get the Legendary Sukumon (prereq for Friend #90), but missing just one Friend won't prevent you from unlocking anything later.

During Shizuru's Route:
One choice, two options. Choose "Keep Going As-Is" to get an immediate bad end.

Akane:
Unlock this route by completing Chihaya's route.
10/6: It Doesn't Matter (to avoid Chihaya route)
10/7: The World
10/16: Go Somewhere Else
10/18: It's Not a Big Deal (to avoid Lucia route)
10/21: Take This Opportunity to Sleep (to avoid Lucia route)
10/23: Watch Her Leave (to avoid Kotori route)
10/25: Stay Here

If you want to get a lot of Friends and Quests done on your initial playthrough, consider following the instructions from "Playthrough 4" (in the next section). The only thing in there you won't be able to do is read the Oppai Ending, but you can easily leave a save on 11/7 to help you get to that ending quickly once you can unlock it.

During Akane's Route:
No choices.

Moon:
Unlock this route by completing all five heroines' routes, then choose it from the main menu.
No choices.

Terra:
Unlock this route by completing Moon, then choose it from the main menu.
Several choices, though only one of them gives you multiple options that actually lead to different outcomes. On that one choice, you get a bad end unless you choose "Let It Go".

Oppai Ending:
Complete all quests, then complete Quest #28: "Proof of Paranormal Phenomena" and never choose "That's Enough".
For this reason, it's best to save Quest #28 for last (or leave a save file on 11/7 before completing it).

===================================
Friends and Quests: Walkthrough
===================================

This is meant to be a step-by-step guide to completing all quests and finding all friends within a reasonable number of playthroughs, so that you don't have to come up with a plan of you own based on the rather large amount of information in the lists below.

--------------------
Playthrough 1
--------------------

First, actually finish reading the entire VN. This completes Quest 31: "Rewrite".
This should be easy to do, but if you need help consult the "Routes: Walkthrough" section above.
Quests #2: "Tsuchinoko Sighting on Campus!?" and #8: "I Have Superpowers" are unavoidable, and 66 of the friends are unavoidable (counting all routes). You will get more quests and friends than that no matter what, but which additional ones is not predetermined. If you're curious, the unavoidable friends are: 1-26, 28-51, 58, 62-63, 81-82, 93, 96, 98-99, 101-106, and 108.

--------------------
Playthrough 2
--------------------

Second, complete Quest #29: "Spoiled end" by getting all bad ends, if you haven't already. You should be able to complete this without any help (see the "Routes: Walkthrough" section if you do need help), and it doesn't make much sense to try completing anything else alongside this, so get it out of the way now.

--------------------
Playthrough 3
--------------------

The goal here is to complete two multi-part quests (#23 and #26, which involve collecting porn books and planting seeds respectively) and a handful of friends (#64, #94 and #95) that we simply can't complete during the last playthrough. Completing quests #23 and #26 and getting friend #64 requires a Kotori-related Mappie segment, and friends #94 and #95 require a Shizuru-related scene, so we'll be going down both of their routes, kind of. I'll also throw in other random friends (like the Sukumon-related ones) which we might as well get out of the way now to simplify the last playthrough.

-----10/3:
Obtain the Legendary Sukumon from a hidden circle: eastern edge, just above path (prereq for friend #90). Note that this circle will not appear if you haven't finished the VN yet.
-----10/4:
Obtain friend #67 by clicking a hidden circle (south of the school).
-----10/6:
Choose "Follow Her" and "Save Her".
-----10/7:
Choose "Myself".
Save at choice. Obtain friend #59 by choosing "Braking".
Reload and choose "Breaking" to prevent Chihaya from showing up in the park on the 20th.
-----10/7 Mappie:
Porn book: 3rd floor, just left of center
Click on a hidden triangle: 3rd floor, second visit, just right of center (prereq for friend #84).
-----10/9:
If you haven't finished Quest #22: "Taste her plate" before, then choose "The Classroom's Fine".
-----10/11 Mappie:
Obtain friend #84 from the hidden circle just SW of the right-hand stairs.
Obtain friend #92 from the hidden circle in the bottom left corner.
-----10/16:
If you haven't finished Quest #22: "Taste her plate" before, then save, choose "Go to the Cafeteria" to complete it, then reload.
Start Quest #26: "Say it with flowers" by choosing "Follow Kotori".
-----10/16 Mappie:
Plant three seeds: 1st floor, two places outside (NE shore of lake, SW of westernmost tree), 2nd floor (NW classroom)
-----10/17 Mappie:
Before choosing either Chihaya or Shizuru, plant three seeds: south of lake, most northeasterly blue building, postbox near west edge. Also, click on a hidden circle (southwest of that blue building) to obtain friend #65.
After choosing Chihaya, find various hidden circles: the park in the center (info #10 and friend #91), west side just under the higher yellow road (friend #66), green area at the bottom (requires friend #84, prereq for friends #85-90)
-----10/18:
Choose "Talk to Her".
Choose "It's Not a Big Deal" (to avoid Lucia route).
-----10/20:
Choose "Go".
If Chihaya doesn't come meet you in the park, you will be given info #6.
-----10/21 Mappie:
Plant one seed in the first alley: roof of 5th upper building from the left
Obtain friend #27 by choosing "Be Honest".
Plant two seeds in the second alley: roof of 6th upper building from the left, alley between 2nd and 3rd lower buildings from the right
-----10/23:
Choose "Follow Her".
-----10/24 Mappie:
Choose "Watch Him", then plant one seed in the fourth alley (after the dogs start chasing you): just under the upper building with stairs (that isn't right on the left edge)
-----10/25:
Save at the second choice.
Choose "Go Check on Shizuru" and control to the 26th to obtain friends #94 and #95.
Reload and choose "Listen to Kotori and Hurry Up" then "Follow Kotori" to get the Mappie segment.
-----10/25 Mappie:
Plant one seed. However, in order to actually plant the seed you must first collect several random items from other hidden circles. Oddly enough, not all of the relevant circles can be found right away, so the order matters a little.
- Click a hidden circle near the bottom just west of the vertical yellow street to get a boomerang.
- Click a hidden circle just under the coffee shop two blocks NE of the yellow intersection to get a magnet.
- Click a hidden circle on the west side of a blue building directly north of the objective to get a cardboard nikuman.
- Click a hidden circle next to a postbox near the NW corner to get an alligator clip.
- Click a hidden circle just SE of the yellow intersection to get an AA battery.
- Click a hidden circle on the sideways L-shaped green patch northeast of the objective. Click a second time to use these items and plant the seed.
Obtain friend #64 by clicking on a hidden circle (top left corner, just under the coffee place).
Porn books: east side between all the blue buildings, west side south of the road west of the hospital, top right corner
After the Mappie segment you will automatically send Inoue a report on the cat that can see ghosts (part of Quest #24: "Seeker of the Truth").
-----10/30:
Choose Quest #6: "Mysterious Building in Town - Rumored Ghost Activity". During Quest #6, find a porn book and friend #107: bottom left corner of big room, 1st floor
-----11/1:
If you planted all the seeds, Quest #26: "Say it with flowers" is completed after talking to Kotori.
-----11/6 Mappie:
Porn book: just under the first horizontal portion of the path. This should complete Quest #23: "Erohim bless you".
Obtain friends #85, #86, #87, #88, #89 and #90 from a series of five hidden circles, each of which is on the path.

--------------------
Playthrough 4
--------------------

Now we're going to try and get every single remaining quest and friend all in one playthrough (though there will be a lot of reloading). Make sure you do every single one of the following steps, even if you already have that particular friend/quest, because quite a few of them are prerequisites for others. It's easier to just do everything rather than try and work out which parts you can get away with not doing.

Most of the remaining quests involve finding "info" then investigating it, and some of these investigation opportunities only appear for Akane, so we'll have to go down her route (this is why playthroughs 3 and 4 can't really be combined). There is exactly one detail with regards to which playthrough 3 is required for playthrough 4 to work: if you've never read to end of Oct 25th after choosing "Follow Kotori", you're missing part of Quest #24: "Seeker of the Truth".

-----10/5:
Obtain info #3 and friends #53, #54, #55, #56 and #57 by choosing "Recruit Members" on Oct 5th.
-----10/6:
Choose "It Doesn't Matter" so that Chihaya won't come to the park on 10/20.

Obtain friend #69 from hidden circle (near bathroom).
As a prereq for part of Quest #25: "Play with Yoshino", click a hidden circle in front of one of the center classroom.

Obtain info #16 by clicking all four non-hidden circles in the first part.
Complete Quest #18: Wonder #5 - "Story of the Stairs" with the hidden circle on the left-hand stairs. Send report to Inoue (part of Quest #24: "Seeker of the Truth").
Talk to all four students. Go through three hallway segments. Kotarou and Yoshino decide to turn back.
In each of the three remaining hallway segments, there is exactly one hidden circle. Find all three.
The circle in the second hallway completes Quest #1: "The Terrifying Old Men". Choose "Yes" to write a report on it.
The other two circles are part of Quest #25: "Play with Yoshino".
After finshing the Mappie segment, you will automatically send your report on Quest #1: "The Terrifying Old Men" to Inoue (part of Quest #24: "Seeker of the Truth"), after which she will send you info #15.
-----10/15:
You will automatically receive info #13 if you sent Inoue reports on quests #1 and #18.
-----10/16:
Choose "Go Somewhere Else".
-----10/16 Mappie:
Click on Lucia on the 2nd floor once (not twice!), then go back to the 1st floor and click a hidden circle on the right-hand stairs to obtain info #21.
-----10/17 Mappie:
After choosing Chihaya, click a hidden circle in the park in the center (info #10 and friend #91).
-----10/20:
If Chihaya doesn't come meet you in the park, you will be given info #6.
-----10/21:
Save at the second choice. Complete Quest #9: "I Actually Do Have Superpowers", reload, complete Quest #10: "I'm the One Who Really Does Have Superpowers", reload, then complete Quest #13: "Doll User". It is important that you do Quest #13: "Doll User" last.
Friends #71, #72 and #79 come with quests #9, #10 and #13 respectively.

You should have completed Quest #30: "100 Friends" by this point.
-----10/30:

For Quest #4: "Cohabitation with Ghosts for No Money Down" - At the second choice, you must choose "Do It Anyway", then skip ahead to the end of 11/2 to actually complete the quest.
For Quest #6: "Mysterious Building in Town - Rumored Ghost Activity" - During the Mappie segment, obtain info #19 from a hidden circle (center of big room, 2nd floor).
Friend #97 comes with Quest #4, and friend #83 comes with Quest #5.
Quests #4 and #7 are also part of Quest #24: "Seeker of the Truth".
-----11/2:
Save at the choice and complete Quests #14, #15, #16, #17 and #20 (Wonders #1, #2, #3, #4 and #7) by reloading. Do Quest #14: Wonder #1 - "Entrance to an Alternate Dimension" last.

-----11/7:
Save here, just in case you missed something and need to come back later to get the Oppai ending.
Choose Quest #21: Wonder #8 - "???". This is the last part of Quest #24: "Seeker of the Truth", so you should complete that as well.
Quest #28: "Proof of Paranormal Phenomena" should be automatically completed in the next scene, if you've completed Quests #13: "Doll User", #14, #19 and #21 (Wonders #1, #6 and #8) in this playthrough (i.e., those aren't the ones you overwrote by reloading saves).
Choices should appear immediately after completing Quest #28 which give you access to the Oppai Ending.
Trigger the Oppai Ending by never choosing "That's Enough".
Friend #100 comes with the Oppai Ending.

Find all porn books in Mappie segments. The easiest one to miss is during the investigation of Quest #6: "Mysterious Building in Town - Rumored Ghost Activity".

These cannot all be done in a single continuous playthrough, so you don't need to worry about trying to do that. Also, all the Japanese walkthroughs I saw had either more or fewer conditions than this, but my own testing implies this list is more accurate.

25) Play with Yoshino

-----10/7 Mappie:
On the 5th floor, click a hidden circle in front of one of the center classroom (prereq for a circle on 10/11).
-----10/11 Mappie:

In each of the three remaining hallway segments, there is exactly one hidden circle.
The circles in the first and third segments are part of this quest.

Choose "I'll Take It" and then "Keep Going As-Is".

26) Say it with flowers

Complete this quest on Nov 1st after finding all eleven seed-planting spots.

-----10/16 Mappie:
Plant three seeds: two places on the 1st floor before going inside (NE shore of lake, SW of westernmost tree) and one place on the 2nd floor (NW classroom)
-----10/17 Mappie:
Before choosing either Chihaya or Shizuru, plant three seeds: south of lake, most northeasterly blue building, postbox near west edge. Also, click on a hidden circle (southwest of that blue building) to obtain friend #65.
-----10/21 Mappie:
Plant one seed in the first alley: roof of 5th upper building from the left
Plant two seeds in the second alley: roof of 6th upper building from the left, alley between 2nd and 3rd lower buildings from the right
-----10/24 Mappie:
Choose "Watch Him", then plant one seed in the fourth alley (after the dogs start chasing you): just under the upper building with stairs (that isn't right on the left edge)
-----10/25 Mappie:
Plant one seed. However, in order to actually plant the seed you must first collect several random items from other hidden circles. Oddly enough, not all of the relevant circles can be found right away, so the order matters a little.
- Click a hidden circle near the bottom just west of the vertical yellow street to get a boomerang.
- Click a hidden circle just under the coffee shop two blocks NE of the yellow intersection to get a magnet.
- Click a hidden circle on the west side of a blue building directly north of the objective to get a cardboard nikuman.
- Click a hidden circle next to a postbox near the NW corner to get an alligator clip.
- Click a hidden circle just SE of the yellow intersection to get an AA battery.
- Click a hidden circle on the sideways L-shaped green patch northeast of the objective. Click a second time to use these items and plant the seed.
