Yūga

A brutal childhood left Yūga, like the rest of the brothers, wholly given over to their cause, ready without hesitation to spend his life for his siblings and their task. Having tasted real suffering, he prizes every fragment of happiness that comes within reach.

Yūga's trump card is Ephemeral Life, a forbidden Haze-Style jutsu held back as a final resort. It summons a spectre that feeds on the caster's own life force to take solid shape, and once embodied the being raises a vast, formidable barrier around its quarry. Fast, powerful, and remarkably durable, it siphons chakra from living things to grow stronger and can even regrow limbs it has lost. Yūga is skilled with the Transformation Technique too, bending it to fool his marks, while the tanto he carries points to kenjutsu training.

Raised in a Land of Haze orphanage alongside his brothers, Yūga later joins the hunt for Hashirama Senju's cells, remains of the First Hokage that have slipped onto an underground market inside the Land of Silence. Dressed as women, the brothers try to coax the cells' location from Kirisaki, but he cools once Boruto Uzumaki shows up in a woman's guise of his own. Tracking Boruto's group, they find the cells in Sakuya's hands. Yoruga's dying sacrifice opens the castle's barrier, letting Yūga, Asaka, and Hiruga slip inside, where Yūga and Asaka cut Sakuya down and seize the prize. When Boruto appears, they frame him for both killings and flee, though Sakuya's dying butler still manages to warn the guards. Later, learning they are being followed, Yūga hands his earring to Asaka and stays behind to hold off the Konoha pursuers, giving his life for the mission just as Yoruga did. His earring is meant to hang beneath the peach tree back at their old orphanage.
