Let Me See You DERQ
You will get this normally.

Nobody Expects the Knock Blow
You will get this normally. If not, you can (probably) activate knockblow by pressing A or the keyboard equivalent when an enemy is about to collide with a character.

She's a Pinball Wizard!
You will get this normally.

Brain Blast
You will get this normally.

Break Ya Neck
You will get this normally. Super Knockback (and Super Knockblow) can also be activated 100% of the time by pressing A or the keyboard equivalent at the right time during the knockback animation.

Wordsworth Scouts Assocation
You will get this normally. It's at the save crystal if you don't know where it is.

Chaos Finale
You will probably get this normally. If not, just go to rural pasture (or anywhere really) and symbol attack, walk on field bugs, escape, repeat.

We Don't Need No Education
Just don't skip the classmate events by ending day early.

Through the Looking Glass
Probably unmissable by the time you get all endings and death ends.

No Pain, No Gain
Pain Area is directly to the right of the first save crystal of the game, just interact with the phone. Ao Oni himself is easily beatable by Mai soloing and doing Studbull -> Rovidbull -> Deus every turn.

Ao Oni Player
Same phone as Pain Area, just playing it once is enough.

You get this through leveling.

Lucil, I'm Home!

In case achievements section was not clear enough.

True End:

• Reach chapter 10.
  
• Beat chapter 10, absolutely do not lose the fight where you do not have Mai.
  
• True End get.
  
• No decisions before this point mattered.

Fallen End:

• Reach chapter 10.
  
• Lose to the 4 butterflies in chapter 10 (the fight without Mai).
  
• Beat up Julietta.
  
• Fallen End get.
  
• No decisions before this point matter.
  
• If this doesn't work, try again with all Death Ends seen. Having none worked for me but my save files might be ♥♥♥♥♥♥.

EX End:

• Do True End on NG+
  
• EX End get.

Step 1: Beat the game however you want, making any decisions you want. Get True End since its easier.
Step 2: Reach chapter 4 in NG+.
Step 3: Clear Pain Area. Mai solo is a viable (and easier) strategy for Ao Oni. Blue Ribbon is your friend. Also attempt the Ao Oni minigame at least once.
Step 4: Reach chapter 10, getting any death ends you missed in first playthrough. Get Al Lily and Clea skills if you didn't already.
Step 5: Make spare save before final boss.
Step 6: Get Fallen End and EX End by doing their respective steps and reload save for the other.
Step 7: Reload save one more time and open up episode chart.
Step 8: Congratulations on 100%.

Alice is dumb and spent time getting to the end of Pain Area with a level 5 Mai so have an extra Mai Solo guide.

Step 1: Have some AGI in equips and Blue Ribbon
Step 2: Deus a lot
Step 3: Reroll field bugs if your damage sucks (like if you are lvl 5)
Step 4: Win
