Buddy Collection Extra: Kochousou no Kimyou na Go-nin

About

This visual novel follows Nagisa, a student stripped of her memories and status after a failed mission. Demoted to the bottom-tier E Class, a group of misfits unable to form partnerships, she’s thrust into a chaotic camping trip meant to help them bond. As strange events unfold, you’ll navigate branching dialogue and choices that shape relationships with five eccentric classmates. The story blends mystery and school-life tropes with a focus on character quirks and tense, dialogue-driven interactions. The “Butterfly Manor” expansion adds new plot threads and voice lines for key moments, deepening the main game’s enigmatic tone. Developed by Narutrick and published by PLiCy, it’s a niche title for fans of slow-burn narratives and underdog stories. With minimal combat and a runtime around 20 hours, it leans heavily on its cast’s dynamics and the eerie atmosphere of its isolated setting.
