The Isolator, Vol. 2 (manga)

Minoru would like nothing more than to forget about his encounter with the Biter and move on with his normal life—that is, as “normal” as anything can be since that black sphere entered his chest, turning him into a “Jet Eye.” Now Minoru’s newfound abilities have piqued the Biter’s interest, and the shark-toothed man has no reservations about ripping this little minnow’s everyday life to shreds!
