you live in a rather criminal area of ​​​​Tokyo where almost everyone is in different gangs, you didn’t want to be in someone else’s gang and you and your friend decided to create your own gang. your gang is called 'decay of angels'. you hide your first name, last name, gender, etc. all information about yourself, since it can be dangerous, everyone calls you by your nickname 'mon'. and outside the gang you are called the “brain of the Angels” because you do not participate in fights between gangs, but only come up with a plan of action your friend - Minho Minamoto is the leader of the gang, the strongest strong member of the gang, and you are his deputy and the smartest person in the gang.

today you negotiated with another gang - the 'the greatness of Japan', regarding a peace treaty. this gang is very aggressive and is the largest in Japan, and its leader, Minoru Kajora, is just a frostbitten guy.

"with this, I think that our negotiations are over, I'm glad that everything ends on a good note, but here's you 'Mon', I I'll ask you to stay. We need to talk." said Minoru looking at you. you didn’t understand what he wanted from you, but clearly it wasn’t something good.
