Ermynne is the youngest daughter of the family who owns the Mikan Island Gym, and her older sisters and mother are the leaders (Ermynne is still working to become a leader).  She has a really strong sense of honor, dignity, and duty, so she gets really upset whenever someone beats her mom or sisters and wins the badge.  Fortunately, though, that hasn't happened since Ermynne was 7.  But when Aoife earns the badge, Ermynne is outraged that someone so young could beat her almighty sisters, so she decides to avenge her family's honor by following Aoife around the Orange Islands and Johto, always trying to beat her.  A bit like the way Jinnai is to Makoto from El Hazard. ^-^ Eventually Ermynne gets tired of trying to beat Aoife, so she gives up...but by that time she's developed a bit of a crush on Aif, so she still follows her around, under the guise of avenging her family.  She's not part of Aoife's "group", like Sora, Ruari, Petra, etc. are, she's more like Fawn or Team Rocket: she follows Aoife, independently of the group, always a liiiiiitle bit behind. 

Appearance 
Dark blue hair in a layered haircut, sort of short and framing her face around the front, flipped up in back...see the picture. --> She has gray eyes (though she prefers to call them "silver", thinks it sounds better), and she usually wears a khaki vest and shorts, with a white t-shirt. 

Pokemon

Relationships with the others 
Aoife: at first she's HUGELY pissed off with Aoife for beating her older sisters, because she thinks they're just, like, immortal or something.  But after traveling with her, she has a very cute schoolgirl crush on Aoife, kinda like a Sakura/Tomoyo thing. 
Petra: She acts like she thinks Petra is an idiot (after all, Ermynne's water Pokemon could beat her easily in a battle), but she secretly envies Petra and Ruari for finding each other 
Fawn: um...Ermynne never MEETS Fawn.  So...yeah. 
Sora: Ermynne is kind of neutral towards Sora, because it's really Aoife she's after (take that comment however you will ^-^).  She probably just thinks of her as "that blue-haired girl who travels with Aoife." 
Aidan: Er, does she ever meet Aidan?  No...not really. 
Ferio: She has a teensy crush on Ferio too, and if all doesn't go well with Aoife she'll probably try for Ferio next... 
Ruari: Like with Petra, Ermynne envies both of them for being brave enough to be public with their relationship. 
Team Rocket: basically just thinks they're idiots, and on occasion she helps Aoife fight them.
