Character development: Yes
Story development: No
Action: Fucking fantastic, regular full page spreads, high paced fight sequences
Awesome shit: T-rexes shooting fireballs, aliens bursting out of children's bodies, serial killers in blackface, Japanese schoolgirls swallowing cum, people getting blown up every chapter, people getting cut in half every other chapter, angry giant Buddha.
Read it. It's all action and no dialog, so it will only take you a day. Anime is shit, doesn't look/feel epic at all, terrible pacing.
