I complet the novel and its one of my favorites novels and i think its Very unique. The world building its infinity better after some time, the Tower, trials, gods, fairy tails. ALL of that mixed Very well and The novel have one of The fews good ends that i read until today. The problem is that this isnt a story to make a manga, because the start is Very slow until they explore more the others worlds in the trials and looks too much generic in the beggining, takes time until he show emotions. So i dont know If i can recomend or not.
