After transmigrating to the night the Uchiha clan was wiped out, the thrill of life and death awakened an overpowered Mangekyo Sharingan ability.
Left-eye ability: Supreme Great Virtue and Evil, the Great Heretical Deity
This ability activates passively, consuming ocular power and chakra to create a vast field. Within it, all emotions radiating outward from living beings, whether positive or negative, are absorbed by the user, increasing their chakra reserves and replenishing all of their expenditures, including ocular power.
Right-eye ability: True Infinite Izanagi
This ability activates passively, using chakra and ocular power as its energy source to constantly correct the user's state, changing anything detrimental to them, including death, stamina loss, and injury, so they remain at their peak at all times.
Damn this godforsaken shinobi world! Today, I'll make it submit! Love me, despise me, hate me! Struggle! Resist! Offer everything up to me!
