What an interesting concept for an anime. The world building of this series had to be the best part about it. That an our hybrid heroine Rinne who helps Kai on his journey to reset this world. While the oblivious MC isn't usually my thing I must say the story, the characters, and the overall concept of worlds being overwritten made for a very good anime. On top of that the action comedy and fantasy elements blended pretty well with the overall story plot. So if you are looking for an alternate reality story with heroes in a fantasy environment then give Why Does NobodyRemember me in this World a watch!
