Remona (レモナ) is Mona's girlfriend.
Remona was originally just a version of Mona with Xs next to her ears, and their name was Kachuusha (カチューシャ) which translates to "Headband". Kaschuusha was a creepy stalker and a crossdresser (the reasoning being that a "real" woman wouldn't confuse hair clips with a headband). However, this characterization was quickly discarded.
Morena (モレナ) is Mona and Remona's daughter. In the lore of the thread where she was created, Mona and Remona were created as bioweapons, so she is also a powerful fighter.
Black Remona (ブラックレモナ) was a bioweapon created to destroy Remona, but she was defeated by Remona's kindness, and became an "older sister" figure to her. She's from the same story as Morena.
Monaka (モナカ) is a derivative of Mona based off of Asuka from Neon Genesis Evangelion.
Jeanne (ジャンヌ) is a sporty character whose cacthphrase is "Jajaan!" (ジャジャーン！) meaning "Ta-dah!". She's insecure about her bust size, and will beat up anyone who negatively comments on her appearance.
