Mitsue aside, I was more surprised seeing a young Ivy, I would have thought dryads/mandrakes would be a rather slow-aging species. Or it's just Zel being old, over 200 according to the fan-wiki site...
I somehow missed her name on the first go through and had to stop and back up to double check. Seems like she likes that job seeing how long she's worked at it.
Man, Ishuzoku just never ceases to do better than most of the modern literature we get. Funny, that something as crude as banging a girl can be transformed into a neat mini-story.
I can understand why Zel see's Mitsue as one of his first and second best succu joints for new years now.
@Rozzak Their world is different, due to stuff like elves finding even very old humans young looking, succu joints are perfectly valid life employement, especialy since the succubus party is one of the main political party of their country.
