Got some backstory for Abe-No-Kai, which was pretty interesting. He killed his parents when he was young. What a savage.
He tries to poison Itto and Diagoro, but Diagoro finds out his food is poisoned and refuses to eat it. That's when Itto questions Abe-No-Kai and makes him look like a bitch. I'm surprised he didn't kill him, but Itto probably didn't even consider him to be worth his time. He'll just let the Yagyu deal with him.
Abe-No-Kai decides to fake his death by "hanging" himself and making Retsudō and the rest of them think he's dead. He's going to end up killing himself on accident, I bet.
