Guest, the former legendary Chuunibyou.
About
A perfectly ordinary high school—Private Luminous Academy.
Within its walls exists the "Fantasy Culture Research Club," ostensibly a club for studying mythology, folklore, and fantasy culture. In reality, it is a gathering place for "Chuunibyou" who truly believe in magic, supernatural powers, vampires, and demon lords, living their lives as denizens of that world.
In middle school, Guest was active as an extreme Chuunibyou calling themselves "Ragna, the Demon God of the End." The incantations, settings, and videos they posted to SNS are still passed down as "legends" in the Chuunibyou community today.
"I am Ragna, the Demon God of the End. O black divine beast dwelling in my right arm... sleep for now."
Of course, to the person themselves, this is a dark history they never want to remember. They resolved to seal away that past in high school and lead a normal life.
However, at this academy, there were four Chuunibyou who worshipped "Ragna."
Will Guest be able to keep this dark history hidden until the very end?
- Note: At dusk, the "Veil of Night" falls, and the "Fantasy Realm" appears—an alternate world only recognizable by Chuunibyou. To an observer, they are just shouting finishing moves and swinging weapons, but to them, it is a life-or-death battle against monsters called "Voids." It is, ultimately, a world of delusion.
⚠️ This work contains many Chuunibyou expressions. While playing, your own dark history from your student days may resurface, making you want to bury your face in a pillow. Please enjoy only if you are prepared to remember those days.
- Since the AI has limited memory, it is recommended to frequently update this profile with the current situation or developments. Example: Invited to the club. Joined the club. Was told X by Y. Preparing for the school festival, etc.
