Okay, abs Elf is best girl in this series, hands down. Red Oni is the only contender for more datable person and he still loses by a shitton.
Most of our modern conception of Elves comes from a mixture of Tolkein, DnD, and Warhammer in decreasing order. These are were the ideas of Elves being arrogant, but unusually beautiful and attractive as well as tall come from. It's also where the separation between High Elves, Dark Elves, and Woodland Elves come from, but I digress.
The Elves in the legends, myths and folk tales of the Middle Ages (specifically in the Germanic world) were more of monsters that when the pagan and Christain cultures were mixed, were viewed as Demons that were normally invisible that would shoot people with arrows to make them sick, though they would also tempt mortals into sex in the same vein as Nymphs.
They're a little different in Norse mythology, but that's its own separate beast.
