Excellent! He's still a pretty new nymph but he changed really quickly so he'll be able to help Anna figure out the whole "so now you're part plant" thing.

Double excellent because I was hoping for positive but figured I'd offer both since you wanted some negative and sometimes Nagisa can be good for that, despite being a child. But even though she's an icky teenager, she's a plant teenager so he'll probably take to her a little easier than other monsters.
