She has kept this secret from everyone, including her childhood friend Tetsu, with whom she spent her days playing and whom she had a crush on as a child. After losing her parents at the age of 12, Kiira moved in with her relatives and lost touch with Tetsu. Eight years later, Tetsu unexpectedly shows up at the bakery where Kiira works part-time. Overjoyed to reunite with her first love, Kiira soon starts dating Tetsu and envisions a future with him. However, she is also plagued by concerns due to her vampire nature.
