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.

History
600 years ago, Kirinmaru lost his 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 until Kagome Higurashi went back in time, and it was transported to the modern era in the. Once there, it formed itself into the being known as Osamu Kirin and 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 the airport 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.

Personality
He 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.

Physical Description
Kirin and Kirinmaru seem to be on similar height, as well as their face partially being concealed. He has light brown hair and wears a pair of glasses, whose eye color is currently a mystery as so far he hasn't been seen without them. He wears a green tie, a light brown trench coat with a blue scarf, and a pair of gloves during Winter.

Relationships
A student of his at Saint Gabriel Academy, he let her first day of tardiness slide much to her shock.
 * Towa Higurashi

He blissfully introduced himself to Towa's relatives, easily recognizing all of them while he was out stargazing. He discussed the comet with him in order to find out how much they know.
 * Sōta Higurashi

Trivia

 * Osamu Kirin's Japanese voice actor (Yoshimasa Hosoya) and English voice actor (Crispin Freeman) both voiced Kirinmaru.
 * He is likely to have 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.
 * It is possible that he, like Riku, is actually an incarnation of Kirinmaru, given that just like with Riku, Kirinmaru is able to see and hear through Kirin. This was proven in "The Barrier of Mount Musubi" where he was interacting with the Sacred Tree of Ages.
