The world has too many flaws (if the villains that appeared in the anime are stronger, because they would follow the plot, being stronger it is obvious that their plans would change, their personalities, etc.) The character follows the canon and acts as a babysitter for isuku (beta), it seems that he had several personalities, it is as if the author did not decide what personality to give the mc, sometimes it is social, other antisocial, sometimes childish, other mature. at the beginning the story had started well but the further you progress the worse it gets, the inconsistencies of the character cannot even be considered comedic. Another thing that annoys says that he does not want to stand out and that his white hair is enough, he lives in a world where there are people who transform into animals or parts (Rumi, his companion who controls the shadows), plants (the hero who literally is a tree) and many more things such as horns (Eri), wings (hawk), tail (his companion), etc, which part of him would make him stand out, he is literally a secondary character that you would never notice, because there are hair colors to heaps in that anime.
