Dorei Shounin Shika Sentakushi ga Nai Desu yo? - Harem? Nani Sore Oishii no?

According to community regulations, Zeolith, the slothful boy, was expected to start vocational school at the age of 15. At 15, a vocational school is aware of its name and choose a career from the list. However, he only received the following titles: "The Brave Man: The Highest Peak of the Human Race," "The Emperor: The Strongest Ruler," "The Wise Man: The Strongest Magician," and "The lowest despicable scums: Slave Merchant." Not a single one of the titles caught my attention. He chose the lowest title, "slave merchant," which is unobtrusive and appears to be a simple one. He is not aware of it yet, though. Although it is the least demanding job, he finds it to be the most powerful and exhausting. A harem fights against being influenced by a wide range of ladies, including the toxic plantgirl, elves, cat-eared adventurer, Loli Demon Lord, and sultry, attractive girls of all ages who are his childhood friends. Unwillingly, this is the story of the strongest slave merchant who achieves great fortune!
