You know, I'm actually concerned for the safety of the lieutenants. They just seem so underpowered afeter seeing a guy like Kira go down in one hit. He was one of the most balanced vice captains who could actually hold his own in battle.
The only vice captain level guys who I see surviving are:
Iba (he goes down so many times, but always comes back. That and he's not an idiot and would keep his distance)
Yachiru (cause if she died, then kenpachi would go ballistic on the quincy and pwn them)
Omaeda (Despite seeming like a bumbling moron, he's actually quite strategic in his moves and can easily escape if he has to)
Yes, Furosuto means Frost in Japanese.
