Eri Shinkai's top three members of the Treasure Hunting Club before she met Aika Sumeragi and Karen Minamino. They were knocked out and captured by Risako and implanted with mind control chips in Secret Game, but were later defeated by Aika.
Despite supposedly being Eri's friends, the harsh tratment they receive, both while being knocked out and later in the handling of their unconscious bodies, doesn't show much care for their welfare or dignity. Eri also doesn't seem at all affected by her friends' fate, even though it's mostly her fault they ended like they did.
Both Midori and Aki get knocked out off-screen by Risako when they leave the rest of the group to go to the bathroom. They are then left unconscious hidden inside a bathroom stall, Midori sitting on the toilet and Aki on top of her, resting on her lap facing the opposite direction and with her legs spread, pulling up her skirt and exposing her panties. It is in this position than Kyoko finds the poor girls when she goes goes looking for them, but she has barely time to react before Risako takes her out with a precise blow to the back of the neck. Kyoko then gasps and falls to the floor, face down and butt raised. Risako now has all the girls she needs for her plan.
Midori and Aki face Aika and Eri on their room armed with tranquilizer guns, but they somehow manage to waste the element of surprise and fail to shoot unconscious any of the girls before they are able to take cover. They are then subject to a constant bombardment of household items by Eri, who throws anyhting she has at her reach at them. The initial objects fail to worry the girls, but when a drawer is sent their way they have no other option than to take cover. Sadly for them, this brief second of distraction is all that Aika needs to close the distance that separates her from the girls.
Before Midori can react, Aika does a floor sweep on her and sends her flying down, lying hard on her back. She then disarms Aki with a precise kick that sends her gun soaring through the room. Without her gun, the helpless girl can only gasp in shock as Aika lunges towards her. She tries to cover her chest with her arms, but Aika goes for the weak spot by landing a demolishing blow to her stomach with her knee. As the girl screams and bends at the waist in reaction to the hit, Aika follows it with an elbow to the back, in a devastating pincer movement wich sends Aki flying upwards, her skirt following suit, exposing her butt. Unconcious, she then slumps to the ground with a loud sigh.
As this happens, Midori recovers and tries to get up before the apparent cover of a couch, gun in hand and still a threat. Eri's scream, however, alerts Aika of the danger, and she hastily goes for Aki's vacant gun, which is conveniently lying right next to the former girl's butt. Despite her considerable initial advantage, Aika somehow manages to outmanouvre Midori and shoot her two times before she even gets to pull the trigger once, one of the darts hitting the brainwashed former ally right in the middle of her breasts. Midori then starts to slowly fall back in shock, conveniently placing herself right behind the arm of a couch, drool starting to emerge from her mouth as she shakes. The camera then pans over her trembling body from head to legs, finally staying at thigh level as the girl lets out a last sigh and unceremoniously slumps forwards head first, chest falling on the couch and butt protruding on the couch arm, skirt obviously hiked up. Later pans of her body show us her furiously blushed face and non-stop drooling mouth, maybe a secondary effect of the tranquilizer darts.
Meanwhile, Kyoko took care without any problems of the other Treasure Hunting Club members together with Risako. However, her luck run out when she was covering the latter's retreat, as the Captain was able to shot a life ring off a wall which fell on her head, hitting her neck and causing her to fall head first on the floor. The unlucky girl lands with her face down and her ass up, skirt hiked up all the way to waist level by the spreading of her legs, a rather unladylike position in which she is later found, and admired, by Gust.
Blond haired member. She was captured and brainwashed by her teacher. She attacked Aika, but was shot in the breasts and knocked out, her body slumping over a couch after some seconds of trembling, legs spread wide and ass sticking out, with the short skirt of her uniform hiked up to waist level to fully expose her panties.The camera pans extensively over her unconsious body, offering many different views. We can see her face is blushed furiosly and a line of drool emerges from her wide open mouth.

Violet haired member. She was captured and brainwashed by her teacher, and attacked Aika alongside Midori. Aika managed to disarm her, however, and knocked her out with a knee to the solar plexus followed by an elbow to the back.
She initially lands on her side, with her skirt hiked up, exposing her butt. However, when we next see her Eri has moved her body. She now lies face down, completely flat, with her leg spread as her friend examines her. The skirt remains hiked up, however, no attemps made to protect the defeated girl's dignity.

Out of the three she has the most screen-time. She was knocked out after she found her friends passed out in the bathroom. She then proceeded to knock out the rest of the members. As her teacher was getting away with Karen, the Captain shot a life ring off a wall which fell on her head, hitting her neck and knocking her out.
She lands with her face down and her ass up, her skirt hiked up to waist level by the spreading of her legs. She lies like this till she is picked up by Gust and taken to the medical bay.

They all appeared throughout the series except Deep Blue Girl where they were sent back home to recover. In the second episode, however, they were only shown unconscious while being examined in the medical bay. During the credits of the third episode, they were waiting with Eri at school, still friends despite the incident.
