Infiltration -Sailor Mars-.Mamoru stops the smaller Usagi, who only had a fake gun. She is subsequently referred to as "Chibiusa". Another evil group, the Black Moon Clan, seeks to target the Legendary Silver Crystal, which could stand in the way of their plans. Upon being taken back to Usagi's house, Chibiusa hypnotizes Usagi's family into letting her stay with them. Meanwhile, Rei helps out with her school's Supernatural Research Club for a school fair, and learns about alleged incidents of people being abducted or spontaneously combusting. Rei's fortune telling booth is challenged by another fortune teller, Koan Kurozuki, who is later revealed to be one of the Spectre Sisters, servants of Black Moon. As the Sailor Guardians confront her, Koan traps Rei in an inextinguishable blue flame. Though Usagi destroys Koan, the blue flames remain unbroken, and Koan's leader Rubeus captures Rei and takes her away.
