Now, from the name, I know what you're thinking.
How could something with that sort of name be any good, right?

Believe it or not, this is one of the most wholesome anime I've watched, and I enjoyed every episode with a smile. Something about it just made me feel a bit happier week after week as it came out, and I just have to recommend it.

Plot: The story takes place in an age where demi-humans, more casually known as "demis", have slowly started to become accepted into human society. Tetsuo Takahashi is a biology teacher who ends up teaching three such demis, hoping to understand more about them while also managing to catch their attention.

It isn't listed as such, but it's quite Slice of Life, and can be quite funny.

Just know that Sakie (the Succubus) is my favourite character, though Hikari's antics are hilarious.
