Tesla Note

Mission T is a secret war between spies and covert intelligence agencies whose aim is to prevent the destruction of this world. The protagonist, Botan Negoro, has trained since childhood and has become the very best scout. She teams up with another agent, Kuruma, to carry out the assignment. Their goal is to recover the legacy of the brilliant inventor Nikola Tesla, known as the "Tesla Shards."

However, the crystals are being sought by agents from other countries, so Botan and Kuruma must do everything they can to outwit them all. Botan Negoro is a student living on the island of Hondo. While all her classmates are making plans for Saturday and Sunday, she slowly reads a book and slowly walks home. When she gets back, she finds that her beloved grandfather is not at home, and two thieves decide to secretly attack the seemingly fragile girl.
