Damn, I finally gave a try on this manga and, this is not easy to put a note. To make it simple, it has a good start, it is very good to see someone have to do some unmorally things to keep going, but the more the plot advances, the more it seems all "fake". Litle by litle, MC just become a generic powerful shonen hero and you realise how others characters are underexploited. And the more the party grows, the less these characters are developped. Just an exemple with his first mate, there relation is really interesting, seeing them trying to evercome one's fears and traumatism is really really good. But once they started to and this big chicken, these scenes stoped. Big chicken-chan may be cute but there is 0 developpement, she is the same 50 chapters later and so go on for all char joining. So to conclude, I would say this started well but ended like generic snowflake soup.
