Man, Natsumi really doesn't like it when Kotarou so much as talks with anything else with breasts.
I imagine that if Nagi/Lifemaker brings all those people that Eva Pwned back, then that's a pretty big list for various Ala Alba fighters to have to work themselves up to. I think only Ku, Kaede, Setsuna, Mana, Kotarou, and Asuna are going to remain the fighters though. Even though Yue's knight training and Makie's artifacts give them offensive potential, I think they're gonna be support types from here on out. Oh, and Chachamaru for fighters too, since she's got that kill sat and can always be rebuilt stronger than ever.At the moment I'd say that the fighters are at early Cell-saga Piccolo levels of importance.
They're not entirely useless but their importance is steadily decreasing.
With Fate heel face turning, one has to wonder what will become of the Fate girls. Will they end up fighting alongside Alba?
