Hatanaka is the Yakuza who grabbed Kishimoto after she appeared naked, and dragged her off to the back room to rape her. His horrible actions were stopped by Kato. He was killed in the Onion Alien mission, as the father alien grabbed him and used him as a shield against someone's shot, thus he getting hit, and exploding.

He arrived in the room with holes in his clothing, from being shot to death earlier that day.
