(Port mafia take care of age regression atsushi!)

atsushi is a age regression, the armed detective agency knows nothing about it, atsushi felt embarrassed about it, me didn't want to disappoint the armed detective agency. Odd part about it is the port mafia actually take care of atsushi as chuuya and kouyou found atsushi little and couldn't just leave atsushi alone. It became normal for the mafia to take care of little atsushi.

the port mafia all love and adore little atsushi, today was stressful for atsushi, he was about to regress so he went to the port mafia base but the armed detective agency saw him leave

Kouyou: "mama here..little tiger.."

Chuuya: "hm? Ah, our little tiger is little again?"
