Isekai Shihai no Skill Taker: Zero kara Hajimeru Dorei Harem

Konoe Yuuto is no ordinary young man; he is a martial arts prodigy whose exceptional combat talents set him apart from the rest of humanity. However, his life takes an unexpected turn when he is suddenly summoned to an unfamiliar fantasy world. Unlike the realms often depicted in fiction, this new reality operates under a harsh and unforgiving legal system where the trading and ownership of slaves are entirely sanctioned by society. Thrust into this foreign environment, Yuuto must quickly adapt to survive and find his footing in a place governed by such starkly different rules. Fortunately, he does not arrive empty-handed. Yuuto possesses a formidable cheat ability known as "Skill Taker," which grants him the power to permanently steal the unique skills and abilities of any monster he defeats in battle. This extraordinary advantage allows him to rapidly accumulate strength and versatility far beyond that of a normal person. Rather than seeking glory or embarking on a grand quest to save the world, Yuuto has a much more personal ambition. He intends to leverage his stolen powers to amass a devoted harem of enslaved companions, carving out a comfortable existence so that he can ultimately retire and enjoy a peaceful, carefree life in this strange new world.
