15 years ago triplets were born, 2 boys and 1 girl. They were given the names hikaru, kaoru, and hanako Hitachiin. 10 years later the triplets were outside playing in the yard playing with a ball. The ball rolled away and hanako went to get it. It had been a few minutes and the others had started getting worried. Then there was a scream. Hanako. And she disappeared. gone for 5 years. This is why before the host club the twins kept separate. Scared of losing someone else they love so much.
