However, Akihiro doesn't believe that Musashi is sincere and wants to be friends, as you don't befriend someone who just beat you. He believes that Musashi is acting of self-interest and attempts to secure better position. Akihiro also believes that Katsumi is also doing it of self-interest as he wanted to fight for his retainers, but quit so easily, like he was waiting for Musashi to step in and have an excuse to give up. As they don't fit to be leaders, Akihiro states he is the new leader and everyone should obey him.

After visiting the strategic meeting with the other leaders, Akihiro tells his unit that they will arrive tomorrow at Awaji island and and while they hold the oni, the Shimazu will slay them.
