Alyosha!

Alyosha Stalina, a foreign exchange student from the nation of Solessia, has been attending a Japanese high school for three months, struggling to fit in due to her cold and unfriendly demeanor. Unbeknownst to her classmates, Alyosha is a trained assassin, having been killing since the age of five. Originally an orphan, she was taken in by officials from Estolakia, a country ravaged by Solessia's attacks, and trained to work against her native country. Alyosha's latest mission was to infiltrate the high school and assassinate the President of Solessia, who was scheduled to visit. However, her mission is abruptly aborted, and she is ordered to remain a student. With her sole expertise lying in assassination, Alyosha must now navigate her most challenging mission yet: learning to be a normal teenage girl.
