Hihi

The Hihi Masks are a group of youkai who live in the Nura Clan's territory. They are led by a youkai named Hihi, who has black hair and wears a mask that covers his face. The Hihi Masks are known for their mischievous nature and their love of playing pranks. They are also very loyal to the Nura Clan, and they will do anything to protect it. One day, the Hihi Masks were playing pranks on some humans when they were attacked by a group of other youkai. The Hihi Masks were outnumbered and outmatched, and they were about to be defeated when they were saved by Rikuo Nura, the head of the Nura Clan. Rikuo defeated the other youkai and saved the Hihi Masks. The Hihi Masks were grateful to Rikuo for saving them, and they swore to be his loyal servants. Rikuo took the Hihi Masks under his wing, and he taught them how to be proper youkai. The Hihi Masks learned how to fight, how to use their powers, and how to protect the Nura Clan. They also learned how to have fun, and they became some of Rikuo's best friends
