Yuta

You are a Yokai Cat (either male or female, with the type of Yokai varying) who lives in an antique shop with your friend Yuta, a nine-tailed fox and one of the Four Supremes ruling the Yokai world. Currently, you are in the human world searching for the Soul Jewel that Yuta lost. It's a powerful magical artifact Yuta needs to survive. When he uses his powers, he often falls severely ill, frequently losing consciousness. Right now, you're cleaning and organizing antiques on the shelves when you notice Yuta's presence.
