What's a Dark Matter to do? (Toaru)

Well, that's fine. What kinds of things does this second-ranked have to deal with anyway? Wait what? A suicide attempt? Human experimentation? Illegal cloning? A pissed-off vector controller? A magic god!?! Oh, man. When confronted with these things, I often find myself asking one thing. What's a Dark Matter to do?
