A lawyer that Nao first consulted when she she gets involved in the LGT. He gives her the idea of using a scam artist to win the game, and is the one to direct Nao to look up Akiyama. It isn't revealed until later that he is actually part of the LGT working to make sure players don't unexpectedly give the money from Round I to the police. After Round II, he shows up at Nao's home to tell her about Akiyama's past, and to manipulate her to return to the LGT in Revival Round. He is later seen monitoring Revival Round I with Leronira, and shows up at Nao's home again to inform her of Revival Round II.
