Isekai Saikou no Kizoku, Harem o Fuyasu Hodo Tsuyoku Naru

Yuuto is suddenly reincarnated into the other world in a smartphone game and becomes the third son of a noble family. “Skills” exist in that world, and Yuuto was reincarnated with “Noblesse oblige.” When Yuuto, who has become an adult, embraces a woman in a ceremony, “Noblesse oblige” is activated. That is a rare skill, the skill that lets him copy the skills of the woman he embraces.
Yuuto embraces women possessing skills one after another, becoming the strongest with the skills he acquires, and building a harem of women who fall in love with him. Furthermore, it was discovered that “Noblesse oblige” can awaken skills and evolve skills, and the cheating keeps on coming! All the women and skills I want are mine. The strongest cheat harem begins here.
