In a world where status and success are defined by divinely granted skills, those blessed with such skills tread upon those less fortunate. Fate Graphite finds himself among the have-nots until a chance encounter activates a hidden ability of his skill.

Unable to stand by and do nothing, Fate follows the kidnapper into his warehouse. While Fate learns to grapple with the nature of the Gluttony skill, he also works to find his place as a new servant at the Hart estate.

Rumors of scores of slaughtered monsters start to circulate throughout the capital, drawing the attention of the holy knights. Fate gets conscripted to take part in a secret mission with Roxy and finds himself going to unexpected lengths to complete it.

Fate accompanies Roxy to the Hart family's lands, where the harvest is taking place. Kobolds have wandered into the area seeking the now plentiful food. Among them is a crowned beast, a creature far more formidable than anything Fate has faced before.

Fate faces off against Hado Vlerick, putting his pilfered power to the test. Roxy arrives in Galia and takes her father's place. Fate follows after her, but along the way, he finds his prior abusers in desperate need of his help.

Fate manages to recover and bring the might of Greed's new form to bear against the gargoyles. Leaving the destruction behind him, Fate encounters an entirely different problem after being reunited with Myne, the mysterious Galian from before.

An unexpected pause in the journey leads to Fate having a chance encounter with Aaron Barbatos, a powerful and experienced warrior. As he trains Fate, Gluttony's hunger leads him to hunt in the castle nearby where shadows of Aaron's past still lurk.

Fate arrives in Babylon and starts adapting to the pace of life and the ludicrous cost of living there. He encounters some of Galia's native monsters. However, Fate quickly discovers that there are threats within the city as well.

An excursion to gather materials for gear upgrades leads Fate to a chance encounter with Roxy once more. Powerful monsters seem to be exhibiting unusual behavior, and derelict chimera shells litter the Great Ravine.

Since returning from the Great Ravine, Fate's found himself in enough altercations around Babylon to get him in trouble with Roxy herself, who challenges him to a duel. Shortly afterward, a death march approaches the city flanked by a masked individual.

After forcing his way into the Domain of E, Fate must face Northern and the Divine Dragon as they move to kill Roxy. As Fate pushes the limits of his newfound power, Gluttony threatens to overwhelm him.
