In a world full of fighters, Hara, the only woman alive, travels through the desert to defeat King Akiles, the most powerful man ever, to prove that she is the strongest in existence.

After the death of her all-powerful grandmother, Hara, the last woman alive, and Tesu, his clunky foster brother, travels through the desert of Kallpa to find King Akiles, the most powerful man ever and the ruler of this continent full of fearsome and brute fighters. Hara believes he killed his grandma, and wants to defeat him in the Infinite Tournament, an all-year event where every fighter can challenge him in order to gain the Belt of Wishes, an artifact that can grant you any wish you want. King Akiles has it a long time ago, wiping out all women, except Hara and her grandma. Because of the tortuous relationship she had with her, Hara wants to prove to everyone that she's capable of defeating the man who killed her, and she's gonna use every medium she can come up with to do it. On the other half, Tesu wants to see her grandma again, and this creates tension between them, only to reveal hurtful truths about her grandma and Kallpa itself.
