Tommy

If Yumika convinces the protagonist and Miyabi not to trespass onto ARSTV's lot, they instead decide to return the mahjong hall, which by now has been open for business for several hours. The only occupant they find is a young boy, who immediately challenges the protagonist to a game.

When the protagonist puts him in his place, Tommy offers to strip as his punishment - despite our hero's explanation that it wasn't that kind of match. Before the boy can continue, his mother Aki appears and puts a quick stop to it.
