Iruma POV

Studying is so hard in the netherworld for me i mean i am only a human and not a demon so how should i know this?!

"Opera-san!" "Yes iruma-sama?" I sighed in relief "can you help me on homework?"
"Yes we can start with the first page"

*two hours later*

"Iruma-sama i believe we are done?"
"Yes you can go opera and ill return the favor one day" i chuckled dryly and opera left soon after. I sighed in relief that i am done with homework

Now i can relax for a bit
