Out of all the characters in SAO, I don't get how someone watches it and comes to the conclusion that Asuna is best girl. There are so many other characters that have far more interesting and compelling backstories and arcs than Asuna that are sidelined because she was first. In my opinion, Alice and Sinon both are more interesting characters than Asuna ever will be. Sinon deals with issues of PTSD and childhood trauma, while Alice tackles the idea of ethics in the context of artificial intelligence and what it means to be a human. Asuna starts off as half-hearted waifu-bait and ends her arcs with some bullshit attempt to make the viewer care for her.
