Oda's New Roommate

Oda Sakunosuke, who had adopted five children, gained a new roommate.

The new roommate had lost his memory. With black hair and blue eyes, he smiled like a charming playboy, but when his expression turned serious, he sent a chill down your spine.

"I think I might have five children, too."

"Also, I don't kill people."

The young man, who gave himself the codename "B," threw himself into the fight against crime.

Does anyone else feel like this is a different genre?
