Blackfox

Rikka Isurugi's family has a long history in the ninja tradition, with her father Allen being a renowned researcher who developed advanced drones with AI capabilities. These drones were intended for civilian use, but other parties had more malicious intentions, leading to a raid on the Isurugi house when Rikka was 16. Rikka survived the attack, but her grandfather Hyoe and father were killed.
