Naruto: Reincarnation Eye at the Start

Reborn in the world of Naruto, Hyuga Lan uses genetic engineering to awaken a golden Tenseigan. Seeking even greater ocular power, he launches his Otsutsuki Gene Completion Project.

Once the test subject's Otsutsuki genes are complete and it absorbs an immense amount of chakra, a mutation occurs.

Seemingly unable to withstand the overwhelming chakra, the subject rapidly swells in size. In the blink of an eye, it transforms into a single-horned giant nearly a hundred meters tall.

Just as Hyuga Lan thinks the experiment has failed, a bloody slit opens across the giant's hideous face. An enormous blue eye, radiant as the stars, emerges from within and begins surveying its surroundings.

The instant the one-eyed giant fixes its gaze on him, Hyuga Lan feels a chill run through his entire body.

He... seems to have unleashed something far more dangerous than he bargained for!
