Want some fun? These two works will guarantee it.
Although Moomin is much more about the characters' daily lives and crazy adventures, Little Witch Academia has a bit of that too. Moomin isn't about witches, but there are witches too.
Both have somewhat unique casts (Moomin more so. Little Witch Academia has some slightly more generic characters, but they're just a few).
