北条 鉄平

Satoko and Satoshi's uncle.

When his brother and sister-in-law passed away, he decided to take them in.

He has a bullheaded, very bad temper, and spends his days violently assaulting Satoko and Satoshi while drinking and gambling.

Teppei and Rina became lovers sometime after the death of the former's wife in 1982 and moved in together at an apartment in Okinomiya. The two make money through gambling and badger games/marriage fraud scams, which involve Rina getting in bed with someone with a lot of money and Teppei catching them in the act, blackmailing and threatening the catch for money.
