A prequel that tells the story of how Hikaru and Kaoru are convinced to join the Host Club. As children, they had a maid they adored but who, in reality, was a thief trying to rob the family safe in the middle of the night. The toddler twins tell her that if she can tell who is who between them, they'll give her the combination to the safe (which they keep hidden in their piggy bank). Unable to tell them apart, the maid breaks open the piggy bank after they fall asleep and robs the family. As she descends a rope ladder from the upper stories of the mansion, the twins wake up and go to her, asking why she broke her promise. She says that she can't tell them apart and, perhaps, no one ever will. This leads to the twins dysfunctional view of others being untrustworthy unless they can tell the twins apart; which of course, no one can. When they meet Tamaki in middle school, he asks them to join the Host Club and they agree, provided Tamaki can figure out which twin is which, giving him a month to do so. Over time, they grow bored and annoyed with Tamaki and tell him to get lost. They go back to being mean and selfish, playing tricks on girls who like them and isolating themselves from others. Tamaki, despite being dismissed, remains determined and finally figures out which twin is which. They dislike his reason of "intuition," but Tamaki helps Hikaru and Kaoru to understand that it's okay to be who they are, just as they are; but if they keep themselves shut off from everyone, they'll never ever meet the person who really can tell them apart. The first host club meeting is held on Opening Day and the twins enter the Host Club, as usual, together.
