To be honest, I really hoped that Kanjuro would change his mind and return as an Oden's retainer because Kinemon and the other was willing to accept him again, but it didn't happen. Their past experiences together weren't enough to change his mind. The Akazaya Nine and even Oden loved him, but the desire for vengeance prevailed in him. It's just sad, but that's the path he chose.
