This would be a nice harem group for a side tale to Monster Musume. Imagine Owen Grady being the "Alpha" of a group of monster girl velociraptors.
Blue has that oldest "sister" feel as well as being second in command of the group while Charlie is the plucky, kid-friendly sister. Echo looks a little Kuudere while Delta is definitely the Tsundere of the quartet.
