According to AniChart the basic premise is the following.

Cocotama are tiny gods born from the thoughts and feelings of objects that people use with great care. The fact that Cocotama wear part of the egg they hatch out of as underwear is proof that they are still apprentices. The Cocotama use a mysterious magic, and they train hard to be of use to humans and to become full gods. They live inside human houses and stealthily move around to help humans find things they have lost, although they make many mistakes.

This looks HNGGG. Very HNGGG. And fills me with a nostalgia from a time when virtual pets were the big thing.

I literally just made a thread about this, only to see you beat me to it several months ago! I need to be more careful next time.

Anyway, the show is out now, but only one episode has been subbed. Apparently the group subbing it is doing it as a side project, so who knows when the next episode might be subbed? I really hope they continue with it though, because I watched the first episode and it was completely adorable. Gotta love the moral -- take good care of your stuff, kids, because if you don't, the newborn baby god inside of it will DIE!

Also, the protagonist's name means "heart". Any show with a protagonist named "heart" is probably going to be adorable.

Oh, and here's the MAL link, for anyone interested.
