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!
