Sword Art Online Alternative: Gun Gale Online

Karen Kohiruimaki always felt out of place in the real world. Due to her extreme height, she found it hard to make friends with other girls her age. Everything changes when she's introduced to VR and Gun Gale Online. In GGO, Karen is free to play the cute, chibi avatar of her dreams. Can Karen find friendship in this bullet-ridden MMO...?

In terms of origin I would say Llen has a better origin since Kirito is just some kid playing a video, where as Lelien in real life is a sexy woman who is surprisingly tall to most characters and is a college student. However, as a protagonist she is annoying but only in the game.

It is overall a good side story but I prefer the other series. That is all i am going to say about it.
