Marz was a member of the S-Rank party [Sword of Divine Silver]. Even though he had the unique skill [Skill Lender] that allowed him to lend skills to his party members, he was ostracized and taken advantage of because he did not fight on the front lines. Eventually, they tried to get him killed by the dungeon boss to avoid paying him his severance pay. Marz retrieved the skills that he lent to his party members with compound interest and instantly became the strongest. He then defeated the boss, obtained a 10/10 waifu and saved a demi-human slave to form a harem.
