When a train bound for Oslo disappears, then reappears and crashes 3km from its tracks, Botan Negoro, a high-school girl trained by her ninja grandfather to save the world, is called in to recover the crystal fragment said to have caused the accident.

It was said that the "Shards of Tesla" that caused the train disappearance case contained a record of the high-frequency and high-voltage generator "Tesla coil" invented by Nikola Tesla. If this "fragment" goes out of control, it could cause great damage, such as warping the surroundings again. In order to prevent the crisis, Peony and the car set out to collect "Shards of Tesla". However, a duo is watching the movements of the peony.

The peony and others have stolen No. 13 of the "Shards of Tesla" scattered all over the world. Jingo glares that it was the secret society organization "Small House" that had been aiming for that ability for a long time. Peony returning to Japan from Norway. In order to find out the whereabouts of "Tesla's Fragment" and the movement of "Small House", he will be living in a share house for intelligence personnel where the car and Ryunosuke live.

In Chicago, USA, an incident occurs in which "Shards of Tesla" seems to have been used intentionally. Three out of four Mafia "Corad Family" executives were electrocuted one after another by lightning strikes. Peony and cars fly to Chicago to find the "Shards of Tesla" that manipulates lightning and the assassin who owns it, commonly known as "Prigiera". While continuing to scout the Collad family, the peony who was involved in the conflict with the rival organization "Black Bloc" is in danger.

Aiming at Theone, the boss of the Collad family, "Prigiera" was Boze, his relative and the No. 2 trusted organization. In addition to Peony and other Japanese teams, CIA Oliver and Mickey will also intervene in the battle for No. 5 of Boze's "Tesla Fragment". However, the power of "Tesla's Fragment" counterattacked Boze, who freely manipulates lightning, and both teams could not find a clue to capture it.

The Japanese team has won the CIA team and succeeded in stealing No. 5 of "Tesla's Fragment" from Boze. However, on the top floor of the Chicago Tower, which was the scene of the battle, a car was shot down by someone. The peony are upset, but their rival Mickey buys a treatment at the CIA. I feel anxious and confused about the unexpected offer, but accept it to save the car. Around the same time, a third force, neither the CIA nor Japan Safety Promotion Co., Ltd., began to move to steal the "Shards of Tesla."
