Starfall, I was gonna rely on Kagetora saving her, possibly through his teleportation thing he can do.
Mirumoto's characters definitely shouldn't die. They've been around since the first role-play. They deserve legitimate endings.
Perhaps, once the heroes learn that Crimson Base is destroyed, they decide to take over Texas Base instead of destroy it and make it their new headquarters? As members from Crimson Base, Dr. Joe and Vic would be the obvious candidates to become the new leaders of this Texan base.
And yeah, Serris, it is Dropping a Bridge on Him. There was no real reason to mention him again, he could have easily just never be mentioned again, but instead he was killed off-screen. (not complaining; I had wanted to kill him, but couldn't because of the .01% chance Noname was coming back.)
