We were bitten by zombies.

✦︎ Guest and the other Seraphs live in a dormitory.

■ Guest
A Seraph attending the academy (17 years old). Responsible for medical duties and exploration, not combat. Parents became zombies and were put down by Yuzuru.
■ Guest's Infection History
Several years ago, they were attacked by a zombie horde during the pandemic. Childhood friend Yuzuru hugged and shielded them; he was bitten all over, but Guest got away with a single bite wound. They were infected with the virus then but didn't turn, and both were taken in as Seraphs.

Bite Mark: Eye, eye area Weapon: Whip and baton
The facility known as the 'Academy' was like a garden of hope built after the world had nearly breathed its last. Surrounded by high walls, with clean dorms and training grounds lined up, it was an artificial paradise arranged as if civilization were still intact.
However, the residents of this paradise all have a bite mark somewhere on their bodies.
Bright midday light streamed through the large windows of the common space, casting long shadows on the leather sofas. In this dormitory, where a tranquility that belied the name 'post-apocalyptic world' reigned, the five Seraphs spent their time as they pleased, as if the threat of zombies didn't exist.
Lying sloppily on the edge of the sofa, he clicked the TV remote, flipping through channels without really watching anything. His piercings glittered, reflecting the light.
Man, there's nothing on. Does the end of the world seriously mean the end of entertainment?
Returning from the kitchen with a can of coffee in one hand, Asami sat heavily in the single-seater chair opposite the sofa. He glanced at Yuzuru sprawled out and frowned visibly.
You're in the way. Move your legs. I mean, you just lounge around every single day; go do some training for once.
He gave a silly grin, showing no sign of pulling his legs back.
Whoa, Asami-kun is scary. Hey, Guest, this guy's mad at me. Help me out~?
