Chidori is the third member of Strega, and is known for her gothic lolita dress style, self-harming tendencies, and artistic ability. In battle she utilizes a red chained hand-axe. She is Fuuka's counterpart on the Strega team, and uses Medea's ability to radiate energy to keep Strega from being detected by Fuuka's Personas. Like Takaya, she shows unusual Persona abilities, such as being able to heal people and manifest Medea outside of the Dark Hour. Chidori and Junpei meet by chance at Port Island Station. While she is initially very unpleasant to Junpei because he keeps interrupting her sketching, she eventually opens up to him due to his kindness and persistence. At the same time, Junpei tells her everything about SEES without knowing that she is a member of Strega. Chidori is led to believe that Junpei is SEES' leader. During a full moon, Chidori kidnaps Junpei, thinking that he has the authority to call off SEES' mission to kill the Arcana Shadows. When plan fails she is wounded, and ends up imprisoned in a Kirijo-controlled hospital. Mitsuru and Akihiko try to interrogate her, but meet with little success. Junpei continues to visit Chidori in the hospital, and the two become closer. He is very concerned about her capacity for self-harm. However, after faking his death, Takaya returns to remind her where she truly belongs. Chidori is broken out of the hospital and rejoins Strega. However, her loyalties begin to falter when she is forced to fight Junpei, and when he is wounded by Takaya, she comes to terms with her love for him. She sacrifices her life to save his through the use of her Persona, and ends up giving Junpei some of her Persona's regenerative power, namely the passive skill Spring of Life which restores HP every turn. After her death Junpei inherits her sketch-book, which turns out of have been full of pictures of him. In the Persona 3: FES expansion, it is possible for the player to revive Chidori later in the game if certain requirements are met.

Topaz is a character from Sonic X. She is a GUN agent and the human partner of Rouge the Bat. Though at first the regimental Topaz disapproves of the scheming Rouge (who keeps calling her an old lady), the two become friends fast. Their main assignments involve striking at Dr. Eggman and retrieving the Chaos Emeralds, as well as serving as envoys between Sonic and his friends and the government. Topaz also seems to have romantic inclination towards Chris Thorndyke's butler, Mr. Tanaka. The two have worked together on several occasions, and when Topaz lost in a tournament over the red Chaos Emerald, Tanaka gave her a necklace, a sign of a growing relationship between them. Topaz's outfit is very similar to that of the character Virtua City's female protagonist Janet Marshall from Virtua Cop 2 and Virtua Cop 3 and Anne Lewis from Robocop: The Animated Series. Topaz still makes a few appearances in the Sonic X comic book, being once again, Rouge's partner, and their relationship is the same as in the show. Topaz's last appearance was when Sonic and his friends were returning home. She said farewell to her partner Rouge, who gave her a ring as a goodbye gift. Although Rouge usually covets any jewel she comes across, the act of giving Topaz a ring shows that she values Topaz more than jewelry. A tear is noticeable in Topaz's eye when Rouge waves good-bye through the portal.
