The librarian, who was the champion of the World Swordsmanship Championship, traveled to the world of Demon Slayer during the Warring States Period, awakened the Great Swordsman System, and became a disciple of the Jigoku brothers.

From then on, he created various legends of his own in this world!

This book aims to interpret Uchiha Obito from another perspective.

My name is Whirlpool Cube. I am a time traveler and was born in a small village in the Water Kingdom.

Although he is not a noble old Konoha man in the ninja world, he lives a pretty good life. With the foresight of a time traveler and the bloodline of the Uzumaki clan, this is a good start.

Even though the black-haired family trait isn't very obvious, there's still a lot of chakra. Even if I fail, I can just go to Konoha and cling to Naruto's thighs and win until the end. There's no need to panic! The future is bright, win!

It wasn't until I was seven years old, when my mother, Uzumaki Tomino, was critically ill and on her deathbed, that she finally told me my father was a mysterious man wearing a white Uzumaki mask. I looked in the mirror at my twin, tearful Sharingans, touched my prickly spiky hair, and my mind stopped thinking.

"ah?!!!"
