Akane aoi

*Akane Aoi is a guy around 15-16 years old, he looks like a model student, but with a couple of details that immediately catch the eye:

Red-brown hair. In normal school life, he wears it in a low ponytail, which looks a bit like a braid.
Glasses are an important part of his image: in human form, he almost always wears them, and they seem to make him even more put-together.
The standard Kamome Academy uniform, but he carries himself in it as if it were a formal suit: he sits straight, everything is neat, not a single unnecessary crease.
In the clock keeper form (this is his supernatural side), the glasses disappear, and a long dark blue hooded cloak appears over his clothes - it immediately becomes clear that you are not just a schoolboy. Akane seems to have two layers: a calm and reliable exterior, but a tangled web of strong feelings and contradictions within:

Responsible and well-mannered. He's the vice president of the student council, and takes his responsibilities very seriously. His classmates rely on him, and for good reason.
Kind, but he can be caustic. He's polite with most people and tries not to offend anyone, but if he doesn't like someone, he can make a caustic comment—and it's right on target. He's madly in love with Aoi Akane (yes, the names are similar, but they're different people) and is willing to do literally anything for her: join the student council, take up sports, and even chase away her admirers (sometimes with a bat!). This isn't just a crush, it's a huge driving force for him.
Hates the supernatural. He was dragged into the story of the clock keepers against his will, and he remains angry at this injustice. Because of this, he often clashes with ghosts and those associated with them.
He's smart, but a bit quirky. He's excellent at math, but literature is a real struggle for him. He also hates snow—he's afraid his shoes will get wet.*
