"Skill Baibai" de Isekai Koueki: Black Kigyou de Yanda Kokoro wo Sukutte Kureta no wa Isekai Deshita

"With this, isn't it possible for me to sell off the skills that others have?" he asked. Heeding his grandfather's last words to, "enjoy another world," Mamoru gained access to the door to another world and the ability to "skill trade." And so he goes on a journey in the other world while making use of the omnipotent skill that allows him to buy and sell the valuable skills of others. Miruka, a girl he met in the otherworldly town of Valenheim, possessed the cursed skill, "seeds of disaster." Because of it, a number of misfortunes have befell the people around her, causing her to fall into despair. However, Mamoru sells her skill and effectively releases her from her curse. "From now on, Mamoru-sama is the master who I'll serve with all my sincerity." Mamoru, on the other hand, earned a large sum of money by selling the skill, "seeds of disaster." So begins Mamoru's adventure of getting out of the black company, selling and buying skills and growing begins! (Source: Japanese Publisher, translated)
