Okay, so Kakerou brought more people than "just" Midara and one referee per player. That's good to know.
Anyway, it's really fulfilling to see Yakou again at this timing. Really ironic, also, seeing how Baku can't get past Kyara's death. 'Cause I bet Yakou doesn't want to be considered Kyara's replacement, nor being constantly compared to him. So maybe Baku's current attitude will upset him?
