Renge Inui

Air Master (Belongs and created by Yokusaru Shibata)
She is the group's extremely short friend. Renge has a penchant for eating obsessively, yet she is always thin (sometimes when she eats a lot, she is shown to have a belly). Renge is the stereotypical overexcited kid with a tendency to whine, but she serves as a cheering squad. She later acquires a kitten that she carries with her most of the time. She also has "psychic" powers.

Ed Master (Fan fic by me)
In the fan-fiction, Renge is very short for her age but she is nice and friendly around her friends, when she meets Ed, Edd and Eddy, she becomes friend with the three Ed boys as her friends, she also starts to have a crush on Ed because of his fun and goofy personality.
