Renako Amaori, a former gloomy and socially awkward girl, reinvented herself for high school and successfully made her debut. She even managed to join the top-tier popular group... only to be suddenly confessed to by two of its brightest stars?! One is the school's ultimate prince, Mai Ouzuka. The other, the beloved angel of the campus, Ajisai Sena. There's no way she can handle both their affections—no freaking way! While still struggling to give them an answer, Renako agrees to help her friend Kaho by joining a cosplay event. It's the perfect excuse to delay her reply... or so she thought. But as she witnesses Kaho's passion firsthand, something begins to stir inside her. What is it that she truly wants? What is she truly searching for? Can she really not become someone's lover? Or has that "no freaking way"... not been so impossible after all?

In the not-too-distant future, the human world has long been overpopulated. Humanity marched to the stars in search of a new home, and just as this was going on, the moon's alignment caused massive earthquakes to ripple across the world, lasting several decades. Humanity was demolished. When the land finally recovered, humanity reemerged to face this strange yet familiar world. Will we, who once lorded over this domain, still remain the masters of this world?

Being a girl of both spirit and human blood, eight-year-old Ellen has power over the elements—though not the traditional four-element kind. She has the power to transform her surroundings by manipulating the elements of the periodic table. On top of that, Ellen also has a great amount of scientific knowledge due to being a scientist in her past life. During the war against a neighboring kingdom, Rovel Vankreift, the hero of the Kingdom of Tenbahl and eldest son of house Vankreift—as well as Ellen's father—was fatally injured. However, the spirit who fought by Rovel's side, Lady Origin, brought him to her realm to save him from the clutches of death. Lady Origin, who happens to be the Queen of the Spirit Realm as well as Ellen's eventual mother, is one of the most powerful spirits in existence, making little Ellen quite powerful in contrast to her innocent looks. But even a family as happy as this one has its fair share of problems, as Ellen and her parents are forced to reconnect their old ties to the Vankreift household in order to defend their relatives' honor—all while hiding Ellen's dangerous existence from the public to preserve their undisturbed happiness.

In a ritual, the Goddess bestows upon 10-year-old children a "class" that shapes their entire future. As the son of the legendary Sword Princess Fara and Archmage Leon—two of the highest-ranked individuals in their respective classes—Arel seemed destined for greatness. Unfortunately, he is branded as classless and thus unable to naturally inherit any kind of specific skill. However, Arel soon discovers that he can replicate the abilities of any class he desires—though doing so demands significantly more effort than it does for the naturally gifted. Eager to test his unprecedented skills even more by finding stronger opponents, Arel sets out to defy the limits imposed upon him and prove that perseverance can surpass even divinely appointed talent.
