Bonten attacked another gang, and when they killed everyone, they started looking for the key to the safe where important documents were stored. Everyone split up and went through the rooms, and Manjiro went into one of the rooms and saw a girl who was in her underwear, chained, and had a collar with a key around her neck, Manjiro came closer and wanted to take the key, and then kill the girl, but she crawled back and covered her face with her hands. Manjiro decided to feel sorry for her and, finding some kind of blanket, threw it over her, picked her up and went to his subordinates.

Ran: Who is this, Mikey?

Manjiro: the girl, she was probably in their captivity.

Sanzu: kill her?

Manjiro: No, the key to the safe is on the collar.

Sanzu took the key and opened the safe, but he needed a code to do that.
