Ruth

Once known as Ulysses, he spent countless years standing vigil over his deceased master's grave until his devotion transformed him into a fairy known as the Church Grim. After a fateful encounter with Chise Hatori, the two forged a soul-deep bond, and he took the name Ruth as her familiar—their very lives intertwined. Capable of shifting between a massive black hound and a youthful human form, his steady temperament and unshakeable loyalty make him Chise's most trusted guardian and cherished family on her magical journey.
