Carlos, a down-and-out aristocratic young man who was framed as a demon spy, accidentally activated the ancient "Seven Sins Source Point" system during his exile across the desert wasteland. Whenever he absorbs the power of different sins, it can be transformed into the corresponding field: arrogance gives him the eye of truth, jealousy generates a data simulator, gluttony awakens and devours genes... Under the city of Purgatory, where he was imprisoned by his former fiancée, he blasted the city wall with the core of the sin of anger, and used the field of greed to turn the enemy into nourishment. When the Seven Sins merged into forbidden divinity, Carlos uncovered the thousand-year conspiracy the demons had buried in the upper echelons of the temple.
