Happy Happia!

Yuki, a tsundere human transfer student, transfers into a special Academy for demi-humans to escape her past trauma. Koneko the crazy catgirl forces her friendship upon Yuki. Koneko's friend, Hako the box-headed ojou-san, completes the group. This is mostly crazy school girl comedy like *Nichijou* or *Asobi Asobase*, where the trivial becomes hilarious. There's the mermaid class rep who can't stop thinking scandalous things about catgirls' butts (purely for the sake of maintaining morals), the too kind elephant teacher, the anti-social bat girl, the crazy goth lolita president of the Fortune Telling Club, and many others. Most chapters involve Koneko spectacularly self-destructing, but it's cute, funny, and sometimes heartwarming - and no significant Drama to worry about.
