Quite boring, the MC encounters deadly situations almost all the time, it's too much to the point of becoming very boring, the only slightly eye catching thing is the novelty of the mc's ability and the fact that he can become a monster, other than that, the main plot, the characters, the world background, and so on are just mediocre. I'm also disatisfied with mc's personality, sometimes he's quite slow to adapt, he was amazed at simple and predictable things. I also have a feeling that things will be quite repititive. Personally, it's not really worth reading. But maybe it's personal taste and other people like it.
