Destiny Star Girlfriend 3

Spring 2019, the first year of the Reiwa era, and Seiji's school life is numbingly predictable — until a mystery assassin shows up to drain his life force. The attacker turns out to be Kanoko, a second-year student at his academy who moonlights as a covert magical girl tasked with defending humanity against threats from deep space. Why would she target a complete nobody like Seiji? The answer traces back to a powerful Majin who destroyed her family. Now the Starry Sky Council has detected an anomaly in Kanoko's body and ordered her to move in with Seiji until it is resolved. The third and final installment of the Destiny Star Girlfriend series.
