On planet Earth, Quirks have evolved to the point of configuring new human races: there are the sub-categories with fairy wings, with mermaid tails, with animal faces...
In this great variety of creatures various kingdoms have sprung up to bring order and balance.
One of the most powerful kingdoms is that of Vulcan, ruled by King Enji, a controversial character who is not loved by everyone.
This imposing man, endowed with an extraordinary Quirk of fire, has red hair like his element, but his eyes are colder than ice, and not surprisingly.
He and his wife, Queen Rei, have six children, studied by the ambitious father to marry the princes of the other five kingdoms, excluding their native one.
Alas... Enji had to brutally clash with reality, that is, that his children hate him or at most are frightened and dodge him.
The eldest son, Touya, has left the castle at the age of thirteen, never to be seen again, causing severe pain in the fourth child, Natsuo, who was particularly fond of his big brother.
And then... There is Anna.
Anna the Quirkless.
The fifth child of the Todoroki family is a beautiful princess, with long auburn hair, halfway between Enji's intense red and Rei's lunar one. With her father she shares the turquoise eyes, the only thing that unites them and that bothers the king, as a daughter without Quirk is a disgrace to him.
To overcome the problem, Enji has turned to his niece, daughter of Rei's brother: Tinker Bell Himura.
She is the same age as Anna, a pretty girl with golden blond hair and bright blue eyes. Her Quirk, Wings of Wishes, allow her to make a wish come true per day, either hers or other people's.
The ruler of Vulcan has asked her to give Anna a Quirk thanks to her lamp genie abilities, but strangely, her power has failed him.
Angered, Enji has taken Anna out of his line of descent, depriving her of her titles and making her a commoner, left to live in the castle solely thanks to Rei and her siblings.
"So be it. She will live in this castle, but she will be treated like a companion." has thundered the fiery king, drawing even more hatred upon him.
Meanwhile, the queen's mental health is deteriorating.
Enji Todoroki has a dream: to extend his dominion over the other five earthly realms: Light, Violet, Aquamarine, Cloud and Underground.
His desire for power and conquest derives not only from his indomitable and insatiable character, but also from the rivalry with the ruler of Light, that Toshinori Yagi admired by the people as the de facto emperor of the entire planet.
The two has grown up together, and the royal families have been animated by great friendship, so much so that it has been hoped for a marriage between Enji's younger sister, Zarina, and the handsome blond with the unknown Quirk. Purpose fallen through, given the will of King Toshinori to remain alone to govern. Since that refusal, relations between the Todoroki family and the Yagi family have deteriorated.
And now... The last thing Enji would have wanted is a powerless daughter, insipid as water, useless as a handful of sand grains blown by the wind.
A heir who wouldn't have generated powerful descendants, a disaster, in short.
The beautiful eighteen year old, after being disowned by her father, has run into the arms of the third child, Elsa, the sister to whom she is more attached to.
"I want to get out of here, my sister. This is no longer a place for me." she has told her, her cheeks wet with tears.
The 21-year-old gasps, panicked.
Anna runs a hand over her face, still shocked, but with a fierce determination in her eyes.
Elsa shakes her slightly by the shoulders, trying to make her give up.
"Anna, what are you saying?! You can't abandon us! Touya is already gone and our mother is getting worse!"
"I'm sorry... But our father destroys everything he touches... You go away too, if you can..."
Nothing could have stopped Anna. Her sister with platinum hair, deep blue eyes and the formidable Ice Creation Quirk can't help but let her go, into the night, like a lowly thief.
