Chronicles of Eden isn't just a story about wild adventures and bringing peace and order to a chaotic world. It's also a tale of horny monstergirls, and to say there's fanservice in the story is putting some of the content very mildly. When it comes to the girls of Daniel's harem there's a variety of not just personalities but also excitable fetishes that the girls have and want to experience, with each girl having a taste for a specific kink that really gets their monster energy burning. Each of their fetishes are listed in their bios and detailed in their pages as they're not just for fanservice purposes but also a way of Daniel accelerating his bond with that particular mate.
The second harem that's coming to be in the story is that of Daemon Warrick and his growing number of attractive followers. Their pages are mostly set in the wiki and they appear to mirror the structure of Daniel and his harem for the most part except for one thing. Instead of a Fetish section these girls have a Harem Role section, detailing how they fight and support Daemon during his journey. While this does reflect the type of harem they comprise it does leave a question unanswered: what kind of kinky stuff do these girls prefer that Daemon might want to know of when the time comes? Although Daemon doesn't use any magic such as Synergy with his followers the girls aren't all that different from Daniel's mates. They have needs and wants too after all. The question is, what would be fitting or even surprising fetishes that these dangerous vixens could have and want indulged with their beloved swordsman?
I invite any and all to voice their opinions and theories to this question. Is it critically important right now in the story? Not really. Is it fun to speculate and imagine? Very much so :)
