Isamu is an oddity even among other werewolves: he had lived in complete solitude for half a decade - from his eleventh to his sixteenth year - and even now he cannot completely revert to his human form. He's also the only known werewolf able to use the magic of the keepers.

Just don't call him L or Jack Frost, okay?
