Though he's often in the middle of a fight, Kanou lives a fairly typical life alongside his bullied friend Yuichi and the lovely Megumi - that is, until the suicides begin.

As Taisuke soon discovers, he's one of the evolved, as is Yuichi; but Yuichi, coerced by other ‘comrades' with similar powers, kidnaps Megumi and leaves with his newfound friends. Taisuke must now head north in an attempt to find Megumi and Yuichi, all the while encountering new friends and dangerous enemies along the way.
A group of people with special powers trying to save the world, fighing with group of evil people with special pwoers trying to "purge it". Similar level of serious content, and explicit content (well Psyren is slightly less brutal I guess). Both start in high school setting, but with all the action twists move to other stages. Both are dark, battle mangas that aren't focusing that much on battles and more on a solid and engaging storyline.
