My name's Luna. I was a single mom, and I died. That was... well, not fine, but it happens. However, I never expected death to involve a demon asking for my soul, and I definitely didn't expect serving a demon to involve reincarnating as a cat! I don't know what the demon wants me to do, but in the meantime, I get to navigate a fantasy world with my summoner, a boy named Nero, and his friend, Alicia.
