小此木 真也

Masaya's father. Had a debt of 50 million Yen on his name which built up over the years from his refusal to pay it because of his obsession with money. He divorced from his wife and ran away from Tsurugigaoka, shifting his huge debt onto Masaya.

His obsession with money grows so intense and uncontrollable that he demands it out of his next of kin; he assaults his ex-wife with a knife when she refuses to give him any,  then kidnaps his son and Chiho for ransom./
