Osamu Kirin

"There's a British proverb that goes like this: "When in you find yourself in Rome, you should do as the Romans do." Which means while visiting an unfamiliar place, blend in."

- Osamu Kirin to Towa Higurashi

 is the English teacher at Saint Gabriel Academy and Towa Higurashi's homeroom teacher. In secretly however, he is also the second daiyōkai incarnation of the dragon daiyōkai Lord of the Eastern Lands Kirinmaru.

History
600 years ago in the, Kirinmaru lost his right arm in a battle with Tōga: he returned to his ship with his severed arm, and Zero ordered Riku to dispose of it. Riku dropped the arm in the Bone-Eater's Well where it stayed to the, once there, it formed itself into the being known as Osamu Kirin until in 2000 in the , Kagome Higurashi went back in time to the Sengoku jidai. He went on to become a teacher at Saint Gabriel's Academy in the.

Osamu Kirin lectured Towa and the fact that she was late and caught fighting with gang members. However, he opted not to tell Sōta and Moe Higurashi, and let the incident slide.

A few days later, Towa was looking out the window during Osamu's class, and he approached her, jokingly saying that whatever is out there won't save her from his class.

Osamu came to as he saw the Grim Comet approaching, and commented that it appears even in the Reiwa era before spotting Sōta with his daughter even his wife arrives from her trip in around the world where the orchestra concert is. He also took notice when Sōta said that nobody else could see the comet with the naked eye.

As Towa continues to be absent from school, he conveniently spends even more time with Higurashi family as he looks for clues about himself. He does not want to tell them why. He looks around and is sad about Bone-Eater's Well (but he didn't know that it's covered by the wellhouse). He stands next to Goshinboku trying to think of what to do without asking them for help.

Personality
Osamu is a very calm and friendly teacher. He does not approve of Towa's fighting, tardiness, and absences. For unknown reasons, he does not punish her. When viewing the Grim Comet, he was shown to be aware of its existence with his glasses, and was stern when understanding that regular humans in the future cannot perceive the comet in the sky. He has an attachment to the Higurashi shrine, his place of birth. His personality is not unlike Riku as he can be as gentle and cunning.

Physical description
Kirin seem to be on Kirinmaru's similar height, as well as his face partially being concealed. He has slightly tanned skin, long brown hair, and wears a pair of dark gray glasses, whose eye color is currently unknown as so far he hasn't been seen without them. He wears a white shirt with a green tie underneath a greenish brown blazer, matching greenish brown pants, and brown shoes. He also wears a light brown trench coat with a gray belt, a grayish blue scarf, and a pair of dark gray gloves during winter.

 * He has a connection with Kirinmaru, given his name, that they have the same voice, and his foreboding notice of the Grim Comet appearing in the Reiwa Era. This was proven in "The Three Princesses Strike Back" where Kirinmaru of the Feudal era states that the comet even does appears in the modern era.
 * He, like Riku, is an incarnation of Kirinmaru, given that just like with Riku, Kirinmaru is able to see and hear through Kirin.
