デビィ・ザ・コルシファは負けず嫌い 5

[DeepL Translation - needs review] Introduction to Volume 1: Rokuro, who has nothing better to do in his spare time, is suddenly confronted by the most powerful demon of all, Deby the Corsican!　She has come to destroy humans, and Rokuro quickly asks her to play a game of Bubba-Dubba...?　The comedy of killing time by playing with a demon that's too good to be true begins, and it's a comedy that will end the human race!
