It was just an ordinary mission, but the red-haired executive of the Port Mafia somehow ended up with a so-called System that keeps throwing bizarre and downright strange things at him every day.
The day before yesterday, it was Alpha pheromones. The next day, he got a harem-protagonist aura. And now it's stripped him of his human status and turned him into a fish!
Nakahara Chuuya: ...Is this something a person does?
But that's not even the worst part. The worst part is that everyone has started looking at him strangely, and even his partner isn't immune!
And let's not forget the white-haired, black-haired, and pink-haired guys in Tokyo, the rabbit boss of the Vongola Famiglia... and all the other people who are somehow involved.
Nakahara Chuuya is speechless. He just wants to say that everyone here is a brother! Can you all leave me alone?
