Very true. That's probably how we'll end up going about it. Pan between separate fights between crew, some of the tougher guys needing more than one crew member to fight. Like, I'm thinking the first time Ryu and Mitsuki fairly fight an Admiral will be teaming up rather than solo. Before they can handle them one-on-one and all. Other than that, we can cut from battle to battle just fine with the crew.

As for the rest of it...that's fair for the fight. So he'll fight the Captain to a standstill and the two Commanders will lose to Mitsuki before he goes to help Ryu. To get to the point of the marines, we could do various things. You could see them bullying citizens and get involved, earning the attention of the others. You could hear about another warrior being executed, like in the anime itself. He probably wouldn't approach the base without a reason, though. So the first point is probably the best, unless he hears rumors.
