I, the Nine-Tails, Have Been Signing In at Konoha for Sixteen Years

Jiuye transmigrates to the world of Naruto and discovers that he has become the strongest Tailed Beast, the Nine-Tails.

He thinks his life as a fox is destined to be bleak, but then he activates a sign-in System. Not only can he sign in anywhere, he also gets the Human-Human Fruit from the Eight Trigrams Sealing Space from the start.

"Ding! Sign-in at the Eight Trigrams Sealing Space successful. Obtained Haki: Observation."

"Ding! Sign-in at the Eight Trigrams Sealing Space successful. Obtained one Asauchi Zanpakuto."

"Ding! Sign-in at Ichiraku Ramen successful. Obtained the Munch-Munch Fruit."

Jiuye sticks to a strategy of steady growth from beginning to end. His main account signs in and develops in the Eight Trigrams Space, while his alt account casually delivers takeout and signs in for even rarer rewards.

Then Pain comes knocking, and Naruto is beaten until he can no longer fight back.

Jiuye decides it's time to reveal his true identity.
