[Welcome to Demon School! Iruma-kun] Shadow of the Demon King

Just writing this for fun, because there are so few Iruma fanfics, and I, as someone who loves everyone (or, more accurately, a doting fan mom QvQ), don't want to pursue anyone _(:з"∠)_, so I decided to play at raising a child. Enter at your own risk. Updates are extremely slow. [They were like a shadow, always staying with their master, until one day, the master disappeared, leaving the shadow behind and going away alone. Where the master is not, there is no need for me to exist either. Do whatever you want with me. If that will bring the master back.] That'll do for the blurb for now. It doesn't quite feel right; I'll revise it when I have time. Theme: Don't just run away from home. Your family will worry.
