This is certainly one of the unexpected find you could ask for. Got into watching this because I like the style of ONE(author) of One Punch Man and since he also created this, I waited for its first release. And it did not disappoint, its art style is my thing with its psychedelic like esper stuff to its simple character designs not centered to attracting via common aesthetics. Even the opening and closing theme is awesome.
I certainly liked the ending and its thorough character development. I really love Reigens character development within the story which lead me to tears by some of the ending scenes.
Totally agree, it catches you from start to finish and I think that the "simplicity" of the design of the characters and then you end up catching each one of them is impressive (I made 2 piercings in my ear as megumu hahaha). But I miss the anime series and wait for each chapter.
