Nikola Tesla, one of the thirteen human warriors chosen by Brynhildr to fight against the gods, was supposed to die at the hands of Beelzebub, the Lord of the Flies, in the eighth battle, but his body merged with another soul that traveled through time, and took the system to travel to Kumogakure Village in the world of Naruto.
Ai: Tesla is simply the lucky star of our Yunyin Village!
Orochimaru: There is no future in conducting human experiments in Konoha. It is better to engage in science with Tesla.
Payne: My pain pales in comparison to Tesla's science.
Ohnoki: I just hate that Tesla is not from Iwagakure.
Uchiha Madara: In terms of dance skills and science, I would like to call Tesla the strongest!
Nikola Tesla: From now on, science will stand at the top of the ninja world!
Let's see how the reborn Nikola Tesla transforms Kumogakure Village into a unique technological powerhouse in the ninja world.
