Do you need more reasons? OK then.
For anyone who's seen S-Cry-Ed (what do you mean you haven't seen it? Go watch it now!) the plot is kind of similar. Even the main villain has nearly identical abilities. Groups of people in Tokyo develop special powers. One group wants to save them. One wants to capture/kill/experiment. Let the fight begin.
It's a set of 6 OVAs and it's absolutely worth watching.
