Lazy Dungeon Master: Volume 5

It's been about one year since I started managing this dungeon with dreams of living a work-free life. A nice and relaxed spring was ahead of me. . . until I ended up thrown into a three-way Dungeon Battle? ! What the hell happened at the Dungeon Core gathering. . . ? Wait, we're on a team with our guardian Core? And Rokuko's guardian is Haku, right? ! Uh, given how romantic things have been getting between me and Rokuko, I'm gonna have to say n-
"I look forward to battling with you on my side, Keima." "S-Same to you, ahaha!"
Am I gonna die before the Dungeon Battle even starts? ! This is Volume 5 of my own lazy kind of dungeon story!
