Alyosha!

Alyosha Stalina, a foreign exchange student from Solessia, has spent three months at a Japanese high school but struggles to connect with others due to her aloof and unapproachable nature. From a young age, she was trained as an assassin by Estolakian officials who took her in after she became an orphan. Her skills were honed to target Solessia, her homeland, in retaliation for its attacks on Estolakia. She was sent on a mission to kill the president of Solessia, who is attending the same school where she has been placed. However, the mission was called off, and she is now instructed to continue as a student. Alyosha has no experience living as a typical teenager and is uncertain if she can adapt to this new, non-lethal role.
