As someone that has closely followed the Layton games for several years, the idea of a Layton anime series excited me. Though, I was a bit skeptical about watching it at first because I was mixed about 3DS Katrielle Layton game and its lack of proper closure to the main story. I watched and closely followed the series in the second half of 2018. The Katrielle Layton anime slowly became a source of happiness as I binged more of the episodes, eventually following the series week-by-week. This review is written from the perspective of a Layton fan, so some of the things I say might read more

As a child I played through all of the Professor Layton games and as you can imagine my overall reaction to finding this series would be the same as any returning Layton fan.

Personally i believe this series does more than justice to the charm and delight of the Layton games.

The art remains the same, keeping the beautiful hand-drawn effect and the soundtrack keeps the same essence as the old but with touches of new aspects, enough to keep the ost from sounding boring and a staright rip from the games.

The plot similar to the Layton games themselves doesnt focus on a in-depth story, in in read more

I have a great mystery for miss Layton as well. How come when a full cycle series (50x23min) casted by no one less than Hanazawa Kana, the most favorited #1 person on MAL and the most well known seiyuu in both Japan and in the West, starts airing, only like 200 people end up watching it by episode 10?

Layton Mystery Tanteisha is yet another overlooked kids anime with wonderful atmosphere and more maturity to offer than any popular shonen anime from current season. From its core, the series is an episodic mystery-comedy. The tales center around our detective, Katri, who meets new clients and read more

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. Katarielle read more
