Batou Jusei

Anime version Sui's father, who died falling off his horse due to drunkenness after being embarrassed by a proposed duel with Karin at Kashin's request. The landlord of Sairyō, he was also a martial artist who took great pride in his practice. Batō requested Kakōton (who was there when he felled) hide the fact how he died to preserve his honor but due to a misunderstanding by some witnesses, many believe Kakōton killed him by Sōsō orders, which led Sui seeking revenge against Sōsō.
