Daigorou

The catalyst for the events that unfurl in Episodes 3 and 4. After a dramatic loss at one of Rikiei's gambling establishments, he is pressured to give up either the deed to his business or his daughter, Osuzu, in order to cover his debt.

[Spoiler] He pleads with Kawara Heitarou for help, suggesting that Rikiei's establishments practice dishonesty. Kawara refuses, citing a lack of evidence. Daigoro has no choice but to give up his store, but Ishimatsu takes Osuzu as well after Sosuke tries to intervene. [/Spoiler]
