Naruto: Reincarnation Eye at the Start

Reborn in the Naruto world, Hyuga Ran activates the golden Reincarnation Eye through genetic modification. To obtain even greater ocular power, he initiates the Otsutsuki Gene Completion Plan. When the experimental subject's Otsutsuki genes are fully completed and it absorbs a massive amount of chakra, a mutation occurs. The subject seems unable to withstand the enormous chakra, rapidly expanding into a hundred-meter-tall, one-horned giant. Just as Hyuga Ran thinks the experiment has failed, a blood-red slit opens on the giant's ferocious face, and a brilliant blue giant eye emerges, scanning its surroundings. The moment that one-eyed giant's gaze falls on him, Hyuga Ran feels a chill run down his spine. He... seems to have stirred up a huge trouble!
