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?!!!"

Traveling through Naruto and becoming a civilian orphan,

How can you survive in the war-torn ninja world?

No golden fingers, no bloodline limits, no family resources.

How can we dance in this chaotic world?

…

"Of all those who have fought me, you are undoubtedly the strongest, even stronger than Hashirama! Come on, young man! Dance to your heart's content!"

"Dancing? I'll blow your head off!"

The world of mutual understanding is the most ridiculous.

The peace of infinite dreams is the most hypocritical.

Darkness, cold-bloodedness and cruelty are the truest portrayal of this world!

So, you wanna dance too!?

Good news: I've traveled through time, to the world of Fairy Tail. Even better news: The magic can summon plants, and not just any plants, but the ones from the Plants vs. Zombies mini-game.
