Duuuuude I love the vibes here. I really hope nothing happens to our adorable little witch though.
He's clearly not seeing the same thing given how revolted she was by the flower gift. It makes me think the whole world is messed up Saya no Uta style and he just...sees things normally, but people seem to interact with him fine (and she lets him go into town and everything) like it's nothing so either he's a wacko, or people and plants are still normal "inside" and just...disfigured?
Kinda makes me wonder if our own heroine is...normal.
