Exactly when in the school-day Mika arrived, she couldn't tell you. It had been one hour, maybe two, since school had started. She stood outside the school, crushing her cigarette beneath her feet in front of a "No Smoking" sign. No reason to break the rules on the first day. No outlying characteristics of hers belied that of a non-human creature - until you looked closely enough. Her canines were partially elongated and her arms seemed a bit too long, but other than that she appeared normal, maybe even average. However, she had missed homeroom, and along with that the chance to meet her non-human classmates. A sigh escaped her lips, and she walked into the office with a slight smirk that disappeared when she saw the scowling secretary.
"Miyamoto. Mika." The woman marked the Jorogumo as tardy, and dug through a pile of papers for what seemed an eternity. Finally, she pulled out a sheet of paper with the name Mika Miyamoto and a list of hours and classes. The secretary raised an eyebrow, remarking that her current class would be math. She was 3 minutes late.
Mika strolled out of the office, as casual as she could force herself to be, and wandered through the empty hallways until she found herself in front of the correct room. She pulled out a pack of gum, sticking a piece into her mouth before she entered the room. From the window she could see some people who were quite obviously non-human - and a few who were harder to notice. But she noticed.
The Jorogumo stepped in, picking a seat at random out of the few open seats. She found herself behind a pair of almost-alike boys and quickly realized that the class consisted of people from all four high school grades. What a weird math class.
