Nuku Nuku is a cat-android hybrid who was created to protect the peace and thwart the evil schemes of the Mishima Corporation.

Nevertheless, she often finds herself forced to use her super-human abilities to protect humanity, usually from the company's malfunctioning products, but will her secret be discovered in the process?
Both series have a similar sense of humor, including their crazy, off-the-wall supporting characters and ridiculous, bizarre situations.
If you like the whole concept of a tree spirit inside the body of a marionette. You'll like Nuku Nuku for the fact that a cat is in a robots body. Both are set in a school environment Although Trouble Chocolate is more romantic then Nuku Nuku. The leading female characters are somewhat the same. Also Magic (TC) vs Science (Nuku).

Haruto Hojo is the son of a priest, which might sound normal. However, his school is the ground zero gathering point for everything ghost, spirit, and likewise, thanks to the obsessed (and also a ghost) headmaster of the school! In order to make sure everything runs normally, Hojo (who just wants to live a normal life), along with Mutsuki (prodigal Japanese priestess), and Kazumi (a frequently possessed monk), complete tasks that only seem to make the school more strange and hectic!
Both deal with protagonists who just want a "normal" life, but seem unable to achieve that! What especially struck me was the similar art style and wacky shenanigans of the characters. If you liked one, the other is worth checking out!
