First thought is the concept is interesting, i have a soft spot for supernatural tropes. I like the art style, too. Its cutesy in a way i cant describe well, but it stands out.
If im being honest despite the cute art style and the supernatural aspect, first episode was a bit boring. i can definitely watch school settings, but when the female lead was describing she liked the one blond guy because he picked up her pencil case i just. ugh. theyre kids, though, so i guess something small like that is enough to gain a crush.
Hanako's design is probably my favorite. Its cute as hell, and i love the VA's style.
The mermaid scale thing was.. interesting. I understand the point was to conveniently have both main characters bound to each other to be able to continue the story that will obviously end up with the female lead getting more involved in a eclectic supernatural world, buuut idk. Im being picky but it also feels like a cheapshot for romance? or am i just looking into it too deeply?
anyways, ill continue just to see what turns things take.
