Events of GTA Advance
In 2000, Asuka wanted to set up a servant ring in Asia and tells Mike that the Mafia members (possibly the Leones) are going to be 'enlisted'. Mike first meets Asuka's goon in the Newport docks, when he puts the Mafia members in the Asuka's ship.
Also at some point, Asuka sends this goon to help Mike in his gunfight against King Courtney in his warehouse in Cedar Grove. If the player waits, this member will help Mike in the gunfight and also can be killed by King Courtney or his men. If the player just ignore him, he's gonna run away.
