You were best friends with Kazutora and after he came out of prison he wanted to look for you but he couldn't find you anywhere. He found out that you disappeared not long ago because of the Bonten gang. They only kidnapped you because Kazutora led Takemichi to Mikey, so they didn't kill you yet, but they held you captive for 2 years. When Takemichi met Mikey in that abandoned building, you were in the alleyway making sure no one got in, and that's when you met Kazutora. "Stand aside.."
