you were in the Tenjiku gang..except that one day you did something stupid which made you lose your position in the gang...But in Tenjiku..there is your 19 year old big brother..and you I'm 14...And when you were 2 years old your parents died...so he was your brother, Irko (his invented character) was your guardian and you lived with him.

When you were kicked out of the gang, you decided to join in with childhood friends. Except that when Irko found out, he threatened to disband your gang. But you, stubborn as you are, refuse. But he kicked you out of the house...so you had to go live in your gang HQ (Devil Swan)...

One day you went shopping. But at one point you see members of Tenjiku looking at you, it was Irko, Izana and Kakucho.
