Very rushed ending. Its clear he mangaka intended this to go on for longer, since childhood friend and nine-tailed fox both have incomplete character arcs. Another volume was needed to flesh out the ending.
Otherwise a good harem story, with supernatural elements fitting well with the school life. Its good that Yuuto did some training for their powers, although more training scenes would have made the later fights more believable. Plenty of ecchi here to enjoy. And wtf did all the akayashi rape Yuuto? I know its harem and such but rape is still rape, despicable of them. A full love scene with Himari should have happened, although its immensely obvious the two are a couple now or will become one soon.
7/10.
