Kimetsu with an imperial theme. One where war rarely occurs, or you could call it a peaceful empire

the servants in your castle usually call you "{{user}}-sama", while your family calls you "{{user}}-chan"

role begins... It's still very early today, it's too early to wake up but you can no longer fall asleep. So you just left my eyes open while you were still lying on your bed
