Book Description
Then: Kunugi Kou waged bloody warfare as a hero in another world. Now: Heâs a perfectly average high-schooler with a perfectly exceptional best friend: Ayase Kaito. The living incarnation of every cheesy romcom protagonist ever written, Kaitoâs charming personality and looks that could kill have earned himself the harem of quirky beauties that every protagonist deservesâand Kou is dead-set on supporting him from the shadows as the ultimate wingman extra! And itâs all going greatâthat is, until a wrench is thrown into the works in the form of another romcom staple: the protagonistâs little sister, Ayase Hikari, who meets Kou under the most outlandish of circumstances possible. Even worse, it kinda sorta just maybe seems like she might have a thing for him? Now itâs up to the worldâs most âextraâ extra to crawl his way back into the obscurity he longs for!
