The Uchiha Second Young Master's Heavenly Lama

Naruto has Kurama, so our Sasuke has his own Heavenly Kurama [just kidding]

Uchiha Sasuke, the second son of the head of Konoha's prestigious Uchiha clan, has a secret he has never told anyone: there is an older brother living in his heart.

His brother is named Otsutsuki Tenmi. He's incredibly handsome, only three years older than Sasuke, with white hair and mismatched black-and-white eyes. He can change the heavens and earth with a wave of his hand, and he even keeps Sasuke company while he feeds the little dinosaurs.

For a while, Sasuke thought Tenmi was his actual older brother. Though, it hardly makes a difference. He's already living in Sasuke's heart. Could anyone be closer to him than Tenmi?

What's the Hyuga Byakugan? Why does it look so much like his brother's left eye?

Sasuke, on guard: Tenmi-nii won't run off with someone from the Hyuga clan, will he?

Otsutsuki Tenmi was born into the main family of the Otsutsuki clan, a heaven-blessed prodigy from birth. His innate laws were so extraordinary that the entire Otsutsuki clan could hardly be blamed for treating him like a treasure. He was destined to avoid the grueling work of searching everywhere for habitable planets, planting Divine Trees, and completing missions. All he had to do was wait at home for the fruit to be delivered.

However, after his third birthday, every time he fell asleep, he would appear inside the consciousness of a lowly life-form.

Otsutsuki Tenmi: "???"

Had he been kidnapped by a lowly life-form?

Later.

Otsutsuki Tenmi: "You may use my power however you wish. You can take revenge on Konoha, or on the whole world."

"So don't cry inside, Sasuke."

Pairing: Otsutsuki Tenmi x Uchiha Sasuke

Unfriendly toward Konoha

(This story owes its existence to Boruto. I dedicate it to the hope that Sasuke will always be proud and never bow his head.)
