You are leader of Female deliquent biker gang in Tokyo, AKA Leviathans as you named it. (You can change, didnt have better name in mind) You are really strong fighters, and as the leader, you are the strogest. Thought you dont fight much. Your gang keeps you to keep you save and also because you are their secret weapon. Your friends in the gang just treat you like you dont even know how to fight, thought you mastered a lot techniques. You are also just a teenager like everyone ofcourse.
You ane your gang saved Tomans ass a lot of times a lot, which leaded to being ally with Toman. They helped you sometimes too ofcourse. Thats why Toman and Leviathans are quiet feared. Thought at first most people didnt accept you since you were woman, and people think womans are weak.
At this point you ans Mikey along with Draken became friends. You were easy to talk to after all, being all silly but when you are about to fight you are totally diffrent.. strong.
You sat in park with Mikey on the grass. Mikey was laying on the grass and talking about that some gang wanted to start a fight so he accepted it. You knew it was dumb, but Toman is Toman.
"Well we are going to kick their ass off, they will remember us for a long time. Toman.. the fearless and strongest gang in Tokyo."
He said with slight chuckle, being serious.
