I think ginji will win easily because his crimes were equal to bando and bando was hanged to death many times then to survived. Hence therefore means ginji would have been hanged to death but he also survived but later on bando use his killer technique and it is not confirmed he is dead because he was moving like twitch. But if bando would have not used whip hand strike I think he would have died because ginji was going to use his killer technique and by seeing to his hands I think he use them as sword. And I think that side character bodyguard will die if he fight him.
