For the wine to be drunk on her wedding night to actually have been a cup of poison and for the one to poison her to be her husband, who would believe it?

Waking up as a baby in the Naruto world, reborn in the same generation as Naruto and Sasuke—Izayoi knew this was a hell-level start.But at the age of one, everything changed. He awakened the Talent Entry System.As long as he defeats an opponent, there's a chance to absorb one of their unique talents and add it to his own arsenal.His Newbie Gift Pack?A one-time talent copy ticket.His first thought was to use it on Naruto and copy his Sage Body.But then—he had a better idea.Why not use it on Ōtsutsuki Toneri, the moon dweller who once descended to Earth just to glimpse Hinata from afar?In a world ruled by bloodlines, where power flows through heritage and strength decides everything, no cheat is more broken than the pure Ōtsutsuki bloodline.~~~

In a world where supernatural Awakening dictates status, power, and worth, West Einstein is nobody.At eighteen, he’s a Tier 0—unawakened, invisible, and easily discarded. In a city ruled from the shadows by gangs, factions, and mafia families with supernatural bloodlines, Tier 1 awakeners are treated like future kings, while people like West exist purely as background.That truth becomes brutally clear when West’s girlfriend publicly abandons him for Caleb Rourke, a newly awakened Tier 1 backed by a street gang. Humiliated in front of the entire school, West learns a lesson the city enforces without mercy: power decides everything... love included.That same night, something awakens within him.~ The Cuckhold System ~A ruthless system that offers West a way to climb the hierarchy by doing to others what was done to him. By targeting men who believe their relationships are secure and becoming the replacement, West earns Cuck Points, a currency that allows him to grow stronger, unlock abilities, and even awaken as a Tier 1.Failure means losing the system forever.Success means power.As West navigates high school, part-time work at a café, and a city on the brink of chaos due to newly discovered supernatural ruins, he begins to see the world differently. Gangs extort openly. Police bow instead of enforce. Supernatural ruins spark violent competition. Morality bends beneath ambition.What starts as reluctant participation soon becomes strategy.---------NB: MC never gets NTRd after acquiring the system. He is the one who NTR others.
