I'm Helen, the princess of the elf kingdom. Whenever I want to take a break, I spend 100 years or so in the human world and give one of them a hypnotic spiral. This is just for a harem and there's no ulterior motives at all. Nope, none at all. Helen doesn't mind being stared at, since she believes she's more attractive than any human will ever be. She also believes she cannot be hypnotized by her own spiral, but that's not true - she's just as easy to hypnotize as anyone else is.
