Welcome to the ultimate achievement guide for Yandere School, a stealth-action game by Tea and Cake Games where you play as Akari Furutaka, a yandere schoolgirl determined to win her beloved Makio-senpai’s heart at any cost. This guide will walk you through unlocking all 13 Steam achievements. This game isn't difficult by any means, quite the opposite actually, but some might need a little help, hence why I decided to create this guide.

This guide is designed to make your journey to 100% completion as smooth as possible. Get ready to eliminate rivals, confess your love, and conquer those nightmares, let's make Senpai yours!

Please keep in mind this is my first time making a guide, so if I describe anything weird or confusing, I apologize.

Chapter 1 kicks off your mission to win Senpai's heart. First, deal with your rival. In this first chapter, your rival is Meisa Ito.

First find a weapon, there's a plethora of them around school, so it should be no issue.
Eliminate Meisa, carry her to the grave, and bury her.

Once that's done, head to the back of the school to find Makio-senpai. Confess your feelings to complete Chapter 1.

This should grant you the "Chapter 1" achivement.

You spawn into school at night In this nightmare, locate a weapon, like before, there's a plethore of them around school. Meisa and Makio-senpai are somewhere on campus, getting cozy.

Track down the Skull symbol, take out Meisa, and Nightmare 1 will conclude.

This should grant you the "Nightmare 1" achivement.

Chapter 2 introduces Angelina, the exchange student. Speak to her, and she’ll ask for a tour of the school, then try to eliminate her by guiding her somewhere secluded.

Then find Makio-senpai in Classroom 3-1 on the first floor. Confess to wrap up the second 2.

This should grant you the "Chapter 2" achivement.

You now play as Akari's teacher. Your task is to eliminate Akari Furutaka, who's in class 2-1. The only weapon in this level is the Katana so you're forced to use that.

Chase her down, kill her, and Nightmare 2 ends.

This should grant you the "Nightmare 2" achivement.

Day 3 ramps up with two targets, Keita, and Ryoichi, and timing is critical. They are together for most of the day so try to get them seperately, otherwise they'll try to take you down.

Wait for Keita to take his smoke break or do a lap around the school. Attack him on the far steps to avoid witnesses. Head back to the baseball field.

When the bell rings and rain starts, follow Ryoichi as he runs toward the school. Remember, make sure not to get noticed!

Then locate Makio-senpai in the Computer Club on the second floor. Confess to end Chapter 3.

This should grant you the "Chapter 3" achivement.

In this nightmare, you’re playing as Makio Sono. There's no threat to worry about here like last time, but if you kiss any girl other than Akari, she'll kill you.

You'll have to find Akari at the school’s entrance, kiss her, and Nightmare 3 will conclude.

This will give you the "Nightmare 3" achivement.

your target in Chapter 4 is Moriyama Yuka, who's getting way too close to Makio Sono. Track Yuka after she parts ways with Makio. Grab a weapon beforehand,

Yuka will pause at the Principal’s Office on the second floor, then head to the Nurse’s Office on the third. Strike on the third-floor hallway for efficiency.

Carry her to the far-end door, head outside, and toss her body over the sloped railing to save time. Take the safest route around the back of the school to the garden. You’ll spot the shovel along the way. Bury her.

Find Makio in Class 3-1 and confess to complete Chapter 4.

This should grant you the "Chapter 4" achivement.

All the students have been turned into Yuka, but only one of them is really her. It's a gamble to see who it really is so it's trial and error until you find the correct one.

Once you do kill the correct one however, that'll end Nightmare 4.

This will grant you the "Nightmare 4" achivement.

Chapter 5 is the final chapter, as well as your final target.

There's two students outside the Nurse’s Office which will complicate things. Firstly grab a weapon and wait for the two students to leave.

Wait for the other teacher to leave who will be in the office, then take out Victoria inside. Take her to the garden and bury her.

Meet Makio in Class 3-1, confess your love, a final cutscene will play and you have official completed the game.

This should grant you the "Chapter 5" achivement.

This achievement requires you to kill a character while they are smoking.

There's multiple ways to do this. The first is in Chapter 1, you can find the teacher of class 3-1 behind the school smoking, kill her.

The second is in Chapter 3. When you eliminate Keita Hiyama (the blonde guy) during his smoke break. Head to the far steps away from the main areas. Wait for him to wander off for a cigarette, and strike when no one's watching.

The third and last is in the final chapter, Chapter 5. Wait until the very end of the day, the nurse and the teachers will be behind the school talking while smoking, kill one of them.

This should grant you the "Smoking Kills" achievement.

This achievement requires you to have some tea and cake in the tea club.

The easiest achievement by far. Simply go to the tea club on the third floor and sit down for some tea.

This will give you the "Tea After School" achievement.

For this achievement, you need to kill a character in the school's bathroom.

This unlocks in Chapter 2 (or anytime you lead a target to a bathroom setup) by killing Angelina Ivanova in a toilet stall. After chatting with her and agreeing to the tour, guide her to the second-floor bathroom, and kill her.

Certain students will also have routines where they'll go to the bathroom, so you can also wait for that and kill them too, which will also grant the achivement.

Once that's done, you'll get the "Dangerous WC" achivement.

This achievement requires you to push a student off the roof.

There's two ways to do this, one is in Chapter 1 with Meisa ITO, at the end of the day after classes, she will go to the rooftoop. Once she's alone you can push her off the roof.

The second is in Chapter 4 with Yuka Moriyama, wait until she lures Makio up to the rooftop for a smooch invite, once he leaves you can push Yuka off the roof.

This should grant you the "Accidents Happen" achivement.
