After being hit by a flower pot, Yu Wan woke up as a poor village girl with an unconscious and fragile mother and a little brother.

She was lost as she did not know this unknown ancient world. But she had to pull herself together, because her mother is still unconscious and her brother was starving.

So she plowed and sowed until she had a large piece of fertile land, rising to the peak of success ever since.

Just as life was getting comfortable, a man, widely feared and rumored to be a living Satan, forced his way through her door, declaring he would marry her!

Although she adored beautiful men, it was rumored that this prince…

“Your Grace, we don’t know each other well!” She said seriously.

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.
