In the manga, after Sailor Pluto called upon time to stop in order to keep Prince Demande from touching the Silver Crystals from the past and future together, because if that happened, they would be sent into oblivion. Since stopping time was the third and most sacred taboo, Pluto collapsed and began to die. Chibiusa at this time was Black Lady. After Sailor Pluto had "died" by using her forbidden ability, Black Lady began to cry and remembered the happy and good times she had spent with Sailor Pluto, and how she was her good friend. One of her tears had turned into a Silver Crystal, which was powerful enough to release her from the dark power controlling mind, and becomes Sailor Chibi Moon for the first time.
