Isekai Saikou no Kizoku, Harem o Fuyasu Hodo Tsuyoku Naru

Synopsis:

Yuuto is unexpectedly reincarnated into a smartphone game world and becomes the third son of a noble family. In this world, "Skills" are a powerful asset, and Yuuto is born with the rare skill "Noblesse oblige." When he reaches adulthood, Yuuto activates this skill during a ceremony when he embraces a woman. "Noblesse oblige" allows him to copy the skills of the woman he embraces—a unique and coveted ability. As Yuuto embraces more women with powerful skills, he becomes stronger with each acquisition, gradually building a harem of women who fall for him. To make things even more broken, it’s soon discovered that his skill can not only copy but also awaken and evolve other people’s skills. With this overwhelming advantage, Yuuto secures all the skills and women he desires, leading to the rise of his unbeatable cheat harem.
