I downloaded Ep. 9 of Disgaea and watched it. It's safe! Kurtis is GREEN again.
His hairstyle is a little different in some screens but the animation isn't all that good at times so that would explain it, ne? Like, his hair is usually all in one direction, but when they show him from the front they'll have one spike jutting off to the side or way up or something. It was really awkward at first but I got used to it. They also really accented his nose in the anime, so he looks sort of like a bird in some shots :D A Kurtis bird...that would be v. funny.
So the anime is safe! Oh the things I do for you people (Tokiya) to confirm stuff. Thanks for pointing out the credits though, that's what inspired me to go on a rampage looking for the episodes. So yeah, he's safe, he's constantly upstaging Gordon, and he's using Thursday as a HUGE plot device. Woo-hoo.
They made his part significantly smaller though. He hasn't had an interesting line yet. So now my beef is not with his hair but with his ridiculously small part. They made him out to be far too evil, as opposed to the justice enthusiast he was in the game. In the anime he's just malicious and even goes so far as to take hostages, but in the game he just fought for what he believed in, even if it did mean the destruction of the Netherworld. He ended up reconciling with Gordon upon his death but I don't see that happening here...I mean, he was grinding Gordon's head into the dirt and enjoying it.
