Faced with losing her position at Witches 5, Eudial creates a computer program to find the true owners of the three Talismans, and learns that Haruka and Michiru are the ones who hold two of the Talismans within their own hearts. They take away Usagi's brooch, the Cosmic Heart Compact, and follow Eudial onto a lonely island. However, the invitation turns out to be a trick, and Michiru’s pure heart is taken, which turns into the mystical Deep Aqua Mirror. Haruka, in order to release her own talisman, shoots herself with Eudial's captured gun. Her pure heart transforms into the mystical Space Sword.
