An arms dealer is reborn as Hotaru Tachibana

A once-in-a-lifetime genius, an unparalleled talent with an almost absurd ability to imitate, and a rising star hailed by the sports world: Hotaru Tachibana.

He gave up a bright future in sports and instead became obsessed with the guns he'd been so good with in his previous life, ruthlessly dominating noobs in gunfight games.

Hotaru Tachibana: Everyone, I'm done being the male lead of a sports anime!! TGC, here I come.

Gunfight game (TGC) players: Please, just act like a normal person!

Setting:

1. Extremely overpowered, pure wish fulfillment

2. A disciple of Yoshida Shoin

3. A combative type, skilled at sniping and close-quarters combat
