※The main story has concluded. I am currently posting irregular short stories (SS-like content).

Kunugi Kou once threw himself into bloody battles as a hero in another world, but now he's just an ordinary second-year high school student you'd find anywhere.

Kou's best friend, Ayase Kaito, is a charming young man with a maximum refreshing aura, like he embodies the protagonist of a romantic comedy.

Surrounding him were a diverse group of girls with unique personalities, again, just like in a romantic comedy: a classic energetic childhood friend, a cool, sharp-tongued honor student with long black hair, a sporty, beautiful girl who's bad at studying... and so on.

In order to build a happy harem with Kaito as the "protagonist," Kou, as the "best friend mob character," provides his full support both overtly and covertly!

Meanwhile, he has a shocking encounter with Ayase Hikari, the "protagonist's sister" and a crucial character in romantic comedies, and unbelievably, Hikari begins to develop feelings for Kou...

A high-energy, unpredictable romantic comedy where the mob character isn't a mob at all!

※Synopsis aligned with the book version.

※Casual character introductions can be found in the activity reports. It's for returning readers, but there are probably no spoilers.
