He was the first post human soldier who fought against the monsters that invaded Earth.
Then a chicken who claims to be an all powerful entity sends him off to another world to get stronger, so that he can face an unknown enemy in the future.
How will he change from a merciless killing machine to a powerful respectful warrior?
It is different from the other transmigration and isekai novels that I read. Unlike the others in which the mc starts off as an op or reincarnates with an op family background or with a system only accessible for the mc to make him get stronger, this one doesn't have a system and also the mc has limited strength and he starts off as an a##hole. At first I thought that it was a joke to name the mc after a cereal, but looking it up made me realise how the author wasn't joking around. I like the setting of the story. But the author could also expand the descriptions and also improve the writing style. In the end it is kinda fun to read.
