PetoPeto-san

Both have children who are not like normal human children. Both handle violence in a way that is suitable for younger viewers. There is a very lighthearted feel to both. 

Both feuture teenagers with their daily lifes of school. Also both have super natural elements. The carry the same atmophere and are slow-paced you need to watch a few episodes before it catches your interet, but give it a shot you wont regret it!!! 

Though petopeto-san lacks battles and superpowers and focuses more on the slice-of-life/comedy part, both anime deal with the issue of the coexistence between human and youkai and the effort to find a way so they can coexist peacefully.  

Both shows are about "supernatural" beings trying to live in human society and the troubles they encounter, which seem to be a metaphor for racism, ableism and other isms. They are similar in tone - heartwarming with some romance and comedy. 

Both series have a very cute, relaxed, pleasant feel to them, and are kid-friendly without coming off as condescending, immature, or boring to an older audience. 

they both have a middle-school set of main characters, both supernatural, and both cute ^-^ i recommend watching them both immediately! 

Both series are set in the countryside, and follow the daily lives of children. They have relatively lighthearted supernatural themes about the magical/spiritual world as a part of daily life.
