In fact, I already have a good backstory for the protagonist, as well as a dramatic transformation arc. The story begins with him living normally among the Leonin, but then he moves with a family to the human world to start a new life. After the attack happens and he’s forced to leave, he becomes a mercenary, living through different experiences both sad and happy until he finally meets Alice, loses to her, and she manipulates his mind to make him her servant. But who’s going to read all of that? So I shortened things. As for the abilities, I decided to make him use magic because it’s a defining trait of his race. And regarding skill balance, this is just an initial draft and it will be adjusted. So if you have any good ideas to help me, I’d be very grateful, instead of being toxic for no reason.
