​On the island of Regalo, a group of supernaturally powered mafia-like protectors called the Arcana Famiglia safeguard the people from any who would harm them. The members of their organization, having made contracts with tarot cards, each possess different abilities, such as overwhelming strength, invisibility, or the power to see into someone's heart. Mondo, their leader and the "Papa" of their family, announces at his birthday party that he will be retiring soon. He plans to hold the Arcana Duello, a competition that, if won, will grant the winner the title of Papa and any wish they desire. But there is more at stake than just a title: Mondo also decides that the winner will marry his daughter, Felicità. Enraged by this, the strong-willed Felicità decides to enter the competition herself, in order to make her own way in the world. As Felicità battles for her freedom, her competitors battle for her heart.

After toiling away in his lab, the alchemist Jolly has finally succeeded in making a personality-swapping potion that is guaranteed to bring him entertainment. The boys of the Arcana Famiglia are tricked into taking the potion and find themselves in bodies that are not their own. With this successful experiment, Jolly has paved the way for a plethora of uncomfortable scenarios. However, despite the boys' desperate struggle to switch themselves back, there is something to be learned from spending the day in someone else's shoes.

"Seiichi Hiiragi is an ugly, revolting, dirty, smelly fatass"—these are the insults hurled at him one after another about his appearance. Such was Seiichi's miserable school life. One day, a voice claiming to be a God announced over the public address system to prepare to be transported to another world. The entire school, including Seiichi, were sent to a fantasy world featuring game-like elements such as levels, stats, and skills. However, the God still had preparations to complete for the transfer, and would send them over as soon as the hero summoning ritual was ready. The classes all formed groups to wait for the transfer, but Seiichi alone was excluded, and as such was summoned to a different area. After being transported, the first thing Seiichi ate was the "Fruit of Evolution," which would come to greatly change his life... This story follows Seiichi from being bullied by his classmates, neglected as a companion, to his hard work, positive attitude, and surviving in this new world. As a result, he becomes one of the champions before he knows it.
