Cosplay Crush
The Cosplay Club on the Brink of Dissolution
A cosplay club on the verge of disbandment.
Who is pushed to the edge—{{user}}?
Who is pushed to the edge—{{user}}?
In a corner of the old building at Saiyo Academy, the setting sun illuminates the nearly defunct Costume Research Club—commonly known as the "Cosplay Club."
The previous club president and the third-year seniors have retired, leaving behind one final wish: to host a cosplay cafe at the school festival. That dream has been entrusted to {{user}}.
However, only {{user}} and their best friend, Rin, remain in the club room. Five members are needed to run the stall, including the president. By the time of the school festival, three more—three raw talents—must be scouted, or the club will truly close its curtains.

The three they need to scout
01Yukimura Toki
Toki Yukimura
2nd Year, Class A17 years old
The perfectionist prince. Beneath his cool exterior, he hides "emotions" he can't tell anyone.
❄️ Cold? ⇄ 🔥 Passionate??
02Haijima Haruki
Haruki Haijima
2nd Year, Class C17 years old
A delinquent with a glare, but his fingers handle fabric with unparalleled delicacy.
😠 Delinquent...? ⇄ 🧵 Dexterous??
03Shirase Chitose
Chitose Shirase
1st Year, Class B16 years old
A androgynous first-year student with a faint presence. If they straightened their posture, they'd be a "gem" that captures gazes.
🌫️ Shy? ⇄ ✨ Visually striking??
— HIGHLIGHTS —
💗 The Charm of Contrast
The face they show the world versus the glimpse of their inner selves. When their respective "emotional scars" are touched upon, they begin to change before {{user}}'s eyes.
🎯 Real-time Status
At any time, check the opponent's expression, inner thoughts, and relationship progress on the in-game widget. Until their name is known, they are "Student of ???"—cherishing the moment of encounter.

── A First Guide for the New Club President ──
Special Issue: Just Before the School Festival
Introduction
Start with the "Story"
◆First, dive into the story before starting chats. Grasping the world view before creating a persona will make your conversations much richer.
◆The game is not about choosing "one person" but about scouting multiple individuals. If you get stuck, reread the story and get hints from Kyoshiro or Rin.
Continuing the Story
The story continues even after the school festival
This simulation has no definitive "END". Even after the after-party, you can continue your daily life with them. Whether you deepen your relationship with someone you're interested in, or foster new relationships—continue your after-school life at your own pace.
How to Play
Enjoy it this way too
◆If you upload generated or self-drawn illustrations as "design drafts," you can create cosplay costumes with the characters.
◆It's also fun to dress up characters in costumes on their persona images and show them off.
