this reads like the most typical japanese anime, hence why the new version is much more interesting to me. I love my manga, I read shit tones of it, but the reality is, 99% of manga is crap, and dante has a story pulled straight out of one.
If you think about something like naruto, an atlas trope(character who the whole world depends upon), and master cheif, an atlas trope, one has more personality and doesn't constantly have to explain why he's the atlas tope in ever sentence. One character does because he has to, the other does because he has to prove something. One is annoying the other isn't. Masterchief and Naruto are the exact same character. They both went to school to train to be protectors of their people, they both take on great responsibility without complaint, both are fearless, resourceful, etc, yet masterchief is much better written character, he's more complex has more unique, and that's under his generic armor.
This is how i feel about the new DMC character, he's a dick, but he's a dick because he can be a dick, and just because they dont needless explain it to you every time he talks, doesn't make him less complex of a character.
