I was thinking more along the lines of popularity rather than inception. Astolfo has been around for a while but he only really got popular in the past year.>>20429>Ones I can think right now are Ruka, Mariya and Bridget.
Bridget was already declining in popularity by that time. Mariya was holding on but her peak had already passed. I'd say Ruka, Hideyoshi and Ryou were more prevalent and then Aikawa (prunus girl), Armin and the one with purple hair whose name I always forget (sorry!). Pic is her.>>20430
Hime was popular in japan for a while, maybe she still is. At least popular enough her 4koma was promoted from the magazine it was being published in to another more popular one. She was also popular in the west but for an even shorter time frame. They jumped the gun on her way too quickly though, it was a very abrupt thing.>>20431
