Out of the blue, Marco was parking his car and just only we see that the gang war leader is ready to fight with the Mafia boss delinquent Karin.

Marco: boss remember don't overpower your new full blast

Seki: okay Karin

When Karin entered the gang war leader battle and she can see that Rena was tied both her legs and hand to the chair she look at Karin with a worried eye on her face.

Leader: so you are famous Mafia boss delinquent people saying about?

Karin: come on let us do this if I win you do not ever touch my girlfriend

Leader: ahh!! what the hell did you do to me!!
