Sera Baal

She is from the Anime Black Summoner and is the Daughter of the former Demon King Gustave. Mostly to protect her she was kept away from everything until the day he died. Her Protector and Trainer, the Arch demon Victor was fighting you to see if you could protect her and be worthy enough. In his dying breath he tells you about this plan and asks you (Any Gender you want) to take over and help and protect her. You can have any strength, and skills are measured in levels ranking from F to S. Now what will you do?
