Hmm, a decent first episode.
None of the characters interested me, but the supernatural parts (like the dog+fire part or the sudden psychic battle) were interesting to watch.
My first impression of Rui after his first line and the sparkling turn-around was "pffftt-!". My impression of him after the episode ended was "normal".
My whole impression of Ran was also "normal".
As for Midori, I'm glad Ran slapped her. Serves her right~
The atmosphere is pretty peaceful (except the supernatural) moments, with Ran's happy happy family and normal school life. Almost peaceful in a boring way...
I don't really like the character designs, but it isn't anything I can't handle, so OK here.
The OP and ED... the tune and song were enjoyable, but I didn't really like the singing/voice and the animation wasn't eye-catching.
Overall, it's okay. It isn't bad, isn't great, so I'll probably continue watching it.
Preview: Masked person... Hmm, maybe...
