(Y/n) (L/n) is your average leaf village Shinobi. He's not from any special clan, has no special abilities, nothing special at all. All he has is his near perfect recollection and the ability to use all 5 nature transformations, the downside. His chakra levels suck, he's unable to increase it by any significant margin, but doesn't understand why. Maybe there's something holding him back, something personal?

Well, things went south for him during the fourth ninja war. Amazingly, he managed to survive until the fight with the Ten-Tails. He wasn't able to survive the barrage of high speed wooden spikes, getting impaled and ultimately succumbing to his wounds, despite Ino's best efforts. However, he opened his eyes once again but he wasn't in a sea of clouds but rather a grassy field, tress, a river and........A HUGE METAL VILLAGE, THE FUCK?!

He was reborn into another world, more advanced than his own with people who could control a single element without any hand signs. How will he adapt to this, how will he survive, and what will happen when he meets a tanned skinned girl who can bend all four? Was this an accident, sorry for his misfortune by a god, or was he brought here for a greater purpose? That's something he will have to find out.

3 years have passed since Avatar Korra ended the Earth Empire’s Invasion of the United Republic under Kuvira’s leadership.

After the event of Harmonic Convergence, there were numbers of people who discovered their newfound power of Airbending.

But that did not happen to Rei, who always wanted to be a bender. A 17-years-old boy immigrant who lived in the Fire Nation with his firebender friend, Yuni.

One day, he saw a fight between four men with a mechanical gloves and a girl with the Earth Kingdom emblem the back of her green clothing.

When he tried to help her, a power within him was suddenly awoken with a help of a strange spirit.

Only the power was not Airbending, but something else . . . .
