Chimera High School

The teachers do work in shifts. When the crepuscular students are in so are the crepuscular teachers. And so on, so forth. It's a boarding school with dorms and a cafe so that students of all types have more chances to interact with each other. And since they're part human staying up when they're supposed to be asleep won't harm them too much as long as they don't do it often.

It's a school that's for human-animal hybrids. It's open 24/5 since different animals sleep at different times. Diurnal hybrids show up to school at 8am and dont get out until 3pm, which is when the crepuscular students will arrive. The crepuscular students will work from 4pm to 8pm before getting what is called "Twilight Zone" (when nighttime starts and when the nocturnal students arrive) and get to go do whatever they want until they have to be back at school at 10pm, where they will stay until 1am. If I'm right I think the three groups (crepuscular, nocturnal, and diurnal) have an hour in between each group. Because crepuscular animals are active at dawn and dusk instead of having to go to school for 8 hours like the nocturnal and diurnal students they have to go to school twice for 4 hours each.
