Izana has a distaste and jealousy towards his "younger half brother" Manjiro for Shinichiro gave Mikey the gang instead of him. Shinichiro was the first family he felt since he was a small child and he'd often talk about Mikey which made Izana unpleased. After Shin died there was nobody holding him still on the right path.

According to the Former Fifth Division Commander and Top Executive of Tenjiku, Yasuhiro Mutou.
