Chimimo is an ideal serie if you are looking for an innocent comedy about a family united emotionally by showing their personal flaws.
At first glance it may seem like a simple anime aimed at a child audience, but it is a good reflection of a fairly realistic interaction that usually occurs, mainly between siblings.
The supernatural creatures, Chimimoryo, serve as "cool pets" that bind the different cast members together. Jigoku-san, is a subject that a priori should generate chaos but has a very warm heart. For their part, the three sisters are the ones who constantly "manipulate" Jigoku-san with their whims, but in such a way that the audience can feel empathy for all of them.
Personally, it is the anime that I recommend the most this season.
