- It was already said that there is no one strong enough to replace Yamamoto on that position, and that was said by Ukitake himself. Kyoraku sure has mind for CC, but when it comes to power, he is weak compared to Yamamoto.We haven't seen enough from Kyoraku to determine his true strength. But I hold the belief that he's stronger than both. He is captain-commander after all, and he was also confident enough to take on Yammamoto.
- Kyoraku was never sure to take down Yamamoto, Nanao, Kyoraku's VC said that both Kyoraku and Ukitake (it was said that these two are as tag team nearly unbeatable) don't stand a chance against Yamamoto.
