Mei - Momoka's evil twin. She's a tough girl who likes getting into fights and doesn't hesitate even when the time gets rough. But her fighting skills are rather violent compared to Momoka's and she claims to have no fears and takes advantage of Momoka's. She might as well kill you without using any other form of powers. Just with her bare hands.
Ami - Aarin's opposite. She's very childish and immature, asking others to do stuff for her or complaining about why she has to do tasks the others ask her to do unlike Aarin's mature nature in harsh situations. But she likes to keep around a patched up teddy bear, claiming each patch and stitch represents her good twin's fears and harsh memories
Kinoko - Kanako's evil twin. A strong leader like her opposite but is far more agile and intelligent, giving her an advantage over Kanako's supposed stupidity. But she likes to force her leadership when she feels the others would rebel.
Akira - Akarin's opposite. She's known as the supposed lone wolf of the group and would often refuse to cooperate despite being their friend. But she chooses to help them due to her doubts of them succeeding any of their plans and strategies, thinking she's far more superior in strength compared to the others.
Shion - Shiorin's evil twin. Like Shiorin, she would sometimes flirt with the other girls or girls outside of the group or act cute to control them. But she rebels against Kinoko due to bad blood between the two and would often try to overthrow her of leadership position, only to be pushed back to her spot by the older girl. But unlike Shiorin, she watches what she eats and is very picky.
Rin - Reni's opposite. A girl who doesn't show her emotions and often quiet about her thoughts. But she's very blunt when conversing and tends to keep secrets from the others. She even knows how to dig into others' most innermost thoughts to scare them.
