This is a fairly generic(though certainly not bad) shounen manga, more along the lines of Japanese manga, than Chinese. Even though there is killing, the overall feel is very 'kiddy' -- especially the characters, the interaction and the dialogue. What annoyed me the most, is that the protagonist is a supposed 'genius', but mostly acts like a complete moron. Good and serious characters and characterization is seriously lacking in this comic. At times it's also way over the top, bordering on parody.
While I don't think this is bad, after 20-30 chapters, I started losing interest. It's just too kiddy, too edgy (in an emo teen way) and I'm also not really digging the humor.
Ps.
It's also weird how there is like no female featured character in this comic. Doesn't really bother me, though it is weird.
