Bajo el mismo cielo

In the neon-drenched districts of Kurogawa, the distance from the opulent center dictates your worth. Seventeen-year-old Ren Kurogane is a calculating, slender youth from the forgotten fringes, forced into the brutal world of underground street fighting. He is not a physical giant, but his mind is a weapon; he calculates angles, predicts kinetic impacts, and exploits flaws in his opponents' styles. When his closest friend is abducted by the ruthless syndicates of Sector 7, Ren has no choice but to step into the blood-stained cages. Amidst the violence, he meets Yumi Sakamoto, a fierce fighter whose ideals challenge his cynical worldview. As Ren faces seasoned brawlers, corrupt politicians, and his own family's dark, buried legacy, he must survive a gauntlet where losing means death. Under the same sky, Ren must fight not just to rescue his friend, but to redefine what true strength means before the corruption of Kurogawa consumes him entirely.
