Inma Tsuihou: Hentai Gift wo Sazukatta Sei de Outo Owareru mo, Onnanoko to "Nakayoku" suru Dake de Chouzetsu Level Up

In a world where an individual’s destiny is entirely dictated by their innate talent known as a "Gift," Erio Scarlet faces a devastating reversal of fortune. Born into a prestigious noble family celebrated for producing generations of Holy Knights, his life takes a scandalous turn during the Gift conferment ceremony when he manifests a highly suspicious ability called "Incubus." Compounding his disgrace, the sole skill attached to this Gift bears the deeply embarrassing name "Peerless." Deemed far too indecent to remain within a lineage of holy warriors, Erio is swiftly banished from the city. However, his exile marks the beginning of an extraordinary journey, as he discovers that indulging his intense carnal urges somehow triggers astonishing personal growth and power. His fate grows even more complicated when his childhood friend, who was blessed with the revered "Sacred Knight" Gift, pursues him into exile. After she takes the initiative and engages in a passionate encounter with him, a barrage of overwhelmingly powerful and risqué skills awakens within Erio. To make matters even more unexpected, the two find themselves bound together by a mysterious Master-Servant contract. Thus begins the scandalous heroic tale of a young man who, armed with an unseemly Gift, rises to greatness simply by getting intimately close to the many girls he meets along the way.
