Botan Negoro is not your average high school girl—she's been trained to be an elite government agent since she was young. She's also an expert on the "Tesla Fragment," which appear throughout the world to cause supernatural chaos. Her mission is to retrieve these fragments, and to do so she teams up with the smarmy, self-proclaimed top agent Kuruma. But this is no easy mission, even for an elite team... An all-new action manga from the writer of Tiger and Bunny!

Botan Negoro, born from a family of ninjas and trained to be the world's best secret agent, is assigned to work with the smarmy but talented Kuruma to track down the Tesla Fragments that contain untold power. The scene shifts to Chicago, where a mafia turf war's heating up. The duo's next mission is to track down "Preghiera," a mystery figure wielding a Fragment that controls lightning. Can they finish the job? The fate of the world's riding on it!

The Tesla Fragments, and the near-supernatural powers they house, have the power to destroy the entire world. Botan, a teen raised as a ninja, and Kuruma, a smarmy but justice-minded agent, have teamed up to retrieve them... but in Chicago, they're caught in a three-way struggle with the CIA and mafia for a Fragment. As they evade threat after threat, the mysterious "Little House," yet another group after the Fragments, finally makes contact with them. Will they ever find a way to complete this mission?!

Pino and Elmo of the mysterious "Little House" reveal (much to Botan's amusement) that their official name is Una Casita, which sounds a lot like "I'm hungry" in Japanese. But she can't laugh about it for long, because Una Casita has a pair of Tesla fragments that lets them dominate in battle! It's all hands on deck as their naval battle reaches its climax!

After personally witnessing the fiery, painful death of Pino by her hands, Botan has lost the motivation to continue working as an agent. But when she returns to her family home to recuperate, she discovers a hidden diary kept by her mother. The pages detail the truth behind Botan's birth... and subsequently, the identity of her long-lost father. How will her mother's love and hope change Botan? Find out as the action shifts to Russia!
