Question before I think of reading it, is the evil protagonist tag due to his actions, others perception of him, his body or something like that? I desire a somewhat of an antihero at worst (in terms of personality and actions), since I usually get too into the characters. Evil protagonists, if pushed moderately far, make me uncomfortable.
The antihero and evil protagonist tags kinda push me away, but at the same time I kinda want to know why they are there for the Reborn as a Tentacle Monster. Can you give me a spoiler for the MC's personality? I love me some spoilers.
The MC will not be heroic all the time he will save people from time to time, however, the world in this novel is brutal its basically hunters vs monsters world and you will that some monsters are able to evolve much like the MC. Hope that helps without spoiling anything.
