This show is criminally underlooked and deserves a lot more attention. The Anime itself is a mystery series where the protagonist Katrielle takes on various cases and solves them by the end of the episode. Unlike Detective Conan, it's closest comparison, this anime rarely has to do with murders, settling on civil cases, with the main overarching mystery being the disappearance of Katrielle's father. It has a more wholesome and grounded approach, making it a great watch for younger children or if you just want to relieve some stress. Even outside of that, the anime is lovingly animated and boasts it's own unique style. Katarielleis voiced by the legendary voice actress Kana Hanazawa and the writing does it's dammed best to show off her talents at every possible situation. Katarielle's charisma, deductive capabilities and go-getter attitude makes her incredibly likable and can even function as an inspiration for younger audiences.
This is a great show and deserves more people watching it. Please don't miss out.
P.S.: This is based on a video game on the 3DS making it a great video game adaptation, which is frankly rare.
