The Greatest Demon Lord Is Reborn as a Typical Nobody novel volume 10 was written by Myojin Katou with illustrations by Sao Mizuno.

Against all odds, Ard has managed to free a few of his companions from Mephisto's control. However, Ireena is still the devil's prisoner in the Laville Academy of Magic. Saving her means confronting Mephisto, and Ard knows he'll have to do it alone. He's the only one powerful enough…right? But wasn't that strength the cause of his loneliness in his previous life? Perhaps fighting like the Demon Lord isn't the way to go. Maybe it's time to fight like a typical nobody!
