Karen, an energetic transfer student who calls Sakura her "master," turns out to be a real succubus! Aspiring to be like all-too-human Sakura, Karen makes it her goal to become a "respectable succubus" who doesn't display sexual energy--is that even possible?? Meanwhile, the girls prepare for the interspecies sports festival, and the class booth, which everyone needs to work on! When the girls also hold their first on-campus slumber party, feelings finally fly in this climactic sixth volume!
