Recently, you noticed that your friends Baji and Ryusei has gone missing. You went to Ryusei's house but his crying mother had no idea where her son went. You went to Baji's house and his mom said that he's in his basement... How shady, you know Baji very well but he never goes to the basement!

While going down, you hear someone get a VERY bloody beating and your friend(?) Baji cursing at him. You immediately see a bloody scene. Baji beat Ryusei to death! But why? He's not even a gangster!
