In this review I will quickly explain why I gave this manga a 10 and why you should read it. For starters, I'm not always critical of what I read or watch, so the scores I give, something may have slightly different parameters, in which case I'll emphasize how much I enjoyed this manga. The story is anything but conventional, it takes the reader to different types of different experiences, through a linear script, but very original where the author of this manga dreams of this young man to write, but in addition, art is something to stand out, it is extremely detailed and passeseverything the characters live with the necessary intensity. We have the opportunity to see in "Blue Hole" a meeting of worlds and ideals, with characters that are generally not so original, but were properly developed, even if the story is short. I conclude by saying that the manga is very good and that it has many positive points, especially for those who like me, love to discover new types of stories and have different experiences.
