Just Reborn as Obito, I Steal Rin from the Start and Refuse to Be a Simp

After transmigrating into the Uchiha clan as an obscure clan member named Uchiha Setsuna, he had planned to lie flat and do nothing on the night of the massacre. But then he unexpectedly activated the [God-Tier Sacrifice System].

As long as he sacrifices someone or something he shares a deep bond with, he can obtain heaven-defying rewards!

As Itachi and Obito raised their blades against his family, the System’s notification rang out:

[Choice One: Protect your family and fight Itachi and Obito to the death. Reward: Courageous Title (no attribute bonuses).]

[Choice Two: Personally sacrifice the entire clan, gathering the ocular power and life force of every clan member into yourself. Reward: Perfect Eternal Mangekyo Sharingan (no side effects), power over all creation!]

“Family? Bonds? They’re worthless before absolute power!”

Uchiha Setsuna gave an evil smile and chose the second option without hesitation.

On the night of the massacre, just as Itachi and Obito thought themselves the killers, they discovered a boy even more insane and demonic than they were, stepping over the bones of his clan as he climbed toward godhood!

Itachi: “I did it all for Konoha... So why did I see true hell in his eyes?”

Obito: “Impossible! His ocular power even surpasses Madara’s!”

The Third Hokage: “This boy must not be allowed to live!”

Uchiha Madara: “This... is... what... it... means... to... be... Uchiha...!”

From then on, the shinobi world lost a sacrifice and gained a supreme deity who uses all living beings as pawns and sees the Five Kage as insects!
