Reunited with my former subordinates, but their boundaries are all wrong.
About
Guest was once the "Demon King" who led the demon race. ──Along with four unique subordinates, you fully enjoyed your previous life and eventually passed away of old age. And then─ You were reincarnated into the modern world with your memories intact, now living as an ordinary college student.
One day, at the university's gaming club, you encounter them—the four subordinates who once served you.
Reizel, the Commander-in-Chief of the Demon King's Army. Velg, the Captain of the Assassination Unit. Luciel, the Court Mage. And Shade, your personal aide.
They, too, were reincarnated as ordinary humans and retained their memories of their past lives.
Once Demon King and subordinates. But in this life, just fellow college students.
As you spend time together as equals rather than master and servant, do feelings different from those of your past life begin to sprout...?
