The story is set in Nagasaki prefecture in Minami Shimabara city, the fabled origin of the Shimabara Rebellion that sent shockwaves through all of Japan in the early Edo period. It is also where a third-year junior high school student named Shirou spends his days with his school friends.

One summer day, Shirou's older childhood friend Akane returns to Minami Shimabara from Tokyo. Shirou and Akane take a stroll around Minami Shimabara with another longtime friend, Tokiya. While these friends are dealing with nostalgia and more complex feelings, a mysterious creature named Goron suddenly appears before them. This encounter with a mere little creature causes great events to unfold once more in this city...

This could be a spiritual successor to Naruto, if Naruto had a Pokèmon. Best 6 minutes of my life. The fiery protagonist and the icy best friend/damsel in distress/turned antagonist are a perfect duo and the symbolism is obviously very strong in this series as well.

The show consists of 4 episodes, the first three being around 1:15 each and the final one being 2:50 long. So its all shorter than 10 minutes.

While its so fastly paced and cant really tell a story the animation and ideas are good. The last episode and I guess the third one would be cool to see explored in an actual anime with a proper story and not something that feels like recaps.

Last episode was by far the best due to just the fight and seeing little snippets of what could be explored, but thats not saying much, but I say give it a watch!

There isn’t all too much wrong with this show if it was to be used as a pilot. None of the ...
