Fate Graphite was born into a world where magical skills shape your destiny. His skill is Gluttony, a seemingly useless curse of unending hunger that has left him shunned and looked down upon. Until one day, after he takes the life of a thief, his true power awakens: he can devour the skill of anyone he kills to feed his appetite. Will he learn to control this gruesome ability for the better?
