Yuehua Ren died, and his consciousness was dragged into a blank space, where he somehow got bound to a System. It kept insisting it would lead him to rule the world with a secret identity, in the exact way an incurable chuunibyou would. And then... then he was still dead.
System (seemingly very reliable): Don't worry, Ren! You can do it! Go on, draw a card first. Your first draw is guaranteed to be an SSR, dear~ That'll be...
Yuehua Ren (punching it): That'll be my [beep]...! Hurry up and give me a secret identity!
System (looking pitiful): Sob, sob. Okay, Ren, no problem, Ren. Don't be so violent, Ren.
And so, Yokohama saw the arrival of:
A chuunibyou kid with purple hair, red eyes, and a wisteria flower painted on his left cheek, who spends all day thinking about saving the world: "Murasaki Shikibu"
An unreliable boy who believes in hitting hard and breaking bones in every fight, has a violent supernatural ability, and could guest-star as a Berserker in the FGO next door: "Mishima Yukio"
A white-haired, mysterious fellow with firm ideals who calls himself the future hope of the literary world and is hopelessly obsessed with writing: "Kawabata Yasunari"
And a whole cast of mysterious literary figures of unknown origin, who go out of their way to avoid the plotters whenever they see them. Some time later, a rising group of ability users called "Ykher" made its mark in Yokohama...
Q: Hey, Yuehua Ren, don't you want to come back to life?
A: Thanks for asking. I'm in Yokohama, playing literary figures and reviving the literary world. What's resurrection? Do not disturb.
Premise: Save the world (no), revive the literary world and show off along the way (yes)
