White Mage Doesn't Want to Raise the Hero's Level Vol. 4

Shina and Irie finally come face (and other body parts!) to face with the Demon Lord! When he discovers that he doesn't have to kill the Demon Lord to get home, Irie begins his preparations to return to Japan, and Shina begins searching her heart. Can she reveal her true feelings for him before he leaves her magical world forever? And what about that certain other sexy heroine who is free to return home, alongside Irie?! This is the climax of the saga, and maybe a few other things!
