Yuzuha

Shin's partner monster. It was found weakened at a shrine and was saved by Shin, leading to a partnership contract by circumstance. It is an Element Tail, commonly known as the highest class monster, the Nine-Tailed Fox. Right after meeting Shin, it was in the form of a young fox and couldn't speak, but after defeating Skullface Lord, it gained the ability to speak. The next day, it also became capable of transforming into a human form or its L size form, "Yuzuel."
