I was just curious what the tag is even doing there.
Especially since if we're going by target demography category conventions and pretend they still mean anything, this show would be shoujo. As for the manga, well... this anime is not the adaptation of the manga. Has anyone even read it, anyway? For all we know it's like the Shinsekai yori manga "adaptation"...
Anyway, I'm not losing any sleep over it, I was just wondering.
