Naruto: Summoning the Omni-King from the Start

She transmigrates into the Naruto world, and from the start it's the night of the clan's massacre.

Just as Obito is about to kill her as a survivor who slipped through the net, she obtains a Summoning System.

"Ding! We have detected your overwhelming desire to survive. Congratulations, you are now bound to the Summoning System!"

"You can summon a new character. Would you like to summon them?"

"Yes!"

"Ding! Congratulations! You've summoned a new character: Zeno!"

From then on, the Shinobi World gains a god who doesn't eat beef and does whatever he wants.
