And of course To also means 10, which of course is referenced in her birthday (haato = 8 10, or August 10th). However Haachama is only half of the gestalt that is Haato and Haachama, so the To split that divides them has to be cut in half, making it 5.
Pretty simple if you stop and think about it for a second, I can't believe I even have to explain it.
