While I'm not a GM by any stretch of the word, I can't help but look over some of these CS and question them a bit.

A Crowd-control character isn't necessarily bad, though it is unnerving just how loaded with shutdowns and paralysis your character has. his first ability, just what prevents him from literally stopping his enemies with just a touch? Direct skin contact? Does it work on creatures who don't have flesh at all, like golems or skeletons? And just how long does it stop them? Five seconds is more than enough to paralyze someone and then slit their necks. Flash Freeze is even more questionable because that's an AoE freeze. While it may be short duration, how does it affect creatures who are immune to cold, like ice-based monsters or creatures constantly on fire? Just how intense is the freezing itself, or is it more like a stun? Does thorn vines rely on plant matter to create the thorns and vines, or can he just make that wherever he can use his magic? I think there was an actual spell in the anime that does something similar, but only does the binding. And while Steal is certainly magical in and of itself, Disarm seems more like a skill thing. But who knows how Konosuba handles such stuff so I'd say Disarm is just a more specific, but powerful form of steal that only removes weapons. Just my two cents.

Doesn't seem too bad all in all, though it could use some more details. Maybe a few more things about her personality? And what exactly does her new abilities as a Nekomimi grant? For Yaj, a human who came to the new world as a new race, he got heighten strength and durability while gimping his magical abilities. From what I've read it looks like Joy is more agile but has lower intelligence, but maybe you can add a bit more details to what a nekomimi grants. It is a god gift after all, so it should be sufficiently powerful. Maybe it gives her the ability to change into a cat, or survive great falls without being harmed, to create claws to slash her enemies, or even have nine lives. Something along those lines anyways.

I don't know who you had in mind for a Co-GM, but I would like to formally ask if you'd accept me as a Co-GM. Some of these people are friends of mines too, so if they cause any trouble I'll make sure to straighten them out. Seems like we have a lot of players now and I'd hate to see this RP grind to a halt because the players don't have a GM to guide them.
