While following Satoshi's trail, Michiko ends up meeting a gang of thugs pretending to be him and his subordinates. However, she gets herself set up in a deadly game by Shinsuke, one of the real Satoshi's henchmen.

Separated from Michiko, Hatchin befriends Rita, a girl of her age who is suffering because her love for an older man is unrequited.

After settling an old score, Satoshi has Michiko delivered to him in order to sell her to Atsuko, but the deal is blown when Atsuko's partner betrays her.
