冨士田 鋭一

On the surface, he is the president of a real estate company, but behind the scenes he is a moneylender.

Coming from a poor family, he has risen to this level with nothing but his bare hands. In the process, he has done many dirty things, and has earned the enmity of no less than 100 people. However, he does not seem to be bothered by such things.

His one-man management also extends to his health care, and he goes to extremes in his extravagance when it comes to drinking and eating, even if his doctor tells him not to. As a result, he suffers from diabetes and is impotent, probably due to his age. For this reason, he often gives his wife, Mineko, SM-like torture to lower her spirits.
