Beranda ni Neko (?) ga Kita

Keita loves cats and hates spiders, when he found a strange creature that's a fusion of the two! For some reason, the spider-kitty becomes attached to him, and he feels compelled to take care of it. And that's only the start of the extraordinary events! The start of a supernatural slice-of-life story!
