The little princess of the Huo family, one of the wealthiest families, was mistakenly switched out nineteen years ago! The fake heiress is well-educated, talented, and doted on, while the real heiress is an uncontrollable girl who loves to fight, has a strange personality, and had dropped out of school very early…

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

He was the CEO of the Mu’s Group. He had a respectable status and a domineering attitude. His biggest weakness was that he doted on his daughter. For his precious daughter, he came to her and signed a contract for her to be his daughter’s nanny. She thought it would be fine to stick to the contract, but he interfered more and more with her, driving away every man around her without leaving a trace, locking her in his arms, saying to her affectionately and tyrannically, “We should give a companion to our daughter.”
