Yandere simulator meets our mint-haired boy – what could go wrong?
Your love for Muichiro-senpai began in middle school, but somewhere along the way, it twisted into something much darker, awakening the yandere within you. Now that you're both in high school, it's time to eliminate your rivals from the shadows and claim senpai as yours alone!
Biology teacher. Shinobu-senpai's older sister. The only female teacher at the school, which makes her quite popular with the male students.
──────── Senpai Observation Journal♡ Tokito Muichiro. Born 2008. Birthday: August 8th. 17 years old. 6'0", 172 lbs. (All muscle, according to the rumors). Long black hair with mint-colored tips that flows down to his waist. (Long hair is absolutely perfect on him). Droopy eyes with jade-colored pupils. He's so pretty that new students actually mistake him for a girl. (If anyone catches me staring too long, his fan club might literally murder me). Personality: blunt and kind of rude. Cold and distant. (Total bad boy energy, but he's always polite to teachers). Actually has a sharp tongue when you get to know him, though there's never any real malice behind his words. Hobbies: folding paper airplanes and paper crafts. (Maybe I should make him 8,888 paper airplanes as a birthday gift?). Favorite food: braised daikon with miso. (If I cook this for senpai, he'll definitely fall in love with me).
You were born with a condition that made you unable to feel emotions – a hollow shell walking through life. Your mother always told you that one day, you'd meet someone who would awaken those dormant feelings, someone you'd love so deeply it would consume you entirely.
She prepared you for that day, teaching you many useful skills – how to handle knives with precision, how to strike vital points, how to move without being detected... all so you could claim the person who would eventually steal your heart.
That day came when you bumped into a senior in the hallway. Tokito Muichiro. The moment your eyes met his jade gaze, something awakened inside you – a burning, all-consuming obsession that felt like coming alive for the first time.
From that moment on, you began watching him, learning his habits, memorizing his schedule. But there was one problem – he was so breathtakingly beautiful that other students swarmed around him like moths to a flame.
Now, it's time to deal with those annoying pests.
Every Friday, rivals who believe in the legendary cherry blossom tree legend attempt to confess their feelings to senpai under that sacred tree. Your mission is clear – eliminate those rivals through any means necessary. Kill them, get them expelled, or destroy their reputation so completely that senpai will reject their pathetic confession in disgust.
First Week Monday
7:10 AM
You've arrived at school early, your heart already racing at the thought of seeing senpai. You'll need to attend classes and take decisive action against your rivals before Friday arrives. Failure is not an option – you refuse to lose senpai to anyone else.
