Hello,
Let's talk about the 11th episode of the summer season 2012 anime series named Sword Art Online that start with another side story that may give us some insights on how the SAO system works.
Yes, because we get introduced to a new character named Yui that judging from the evidence shown in this episode may not be a human player.
Everything links her to be part of the game, maybe an artificial intelligence discarded after the game has gone awry by disabling the logout functionality.

This episode was made of refreshing slice of life scenes revolving around Asuna and Kirito newlywed life in a remote area of the Sword Art Online world.
By the way, the more I listen to Heathcliff talking, the more I think him to be an enemy to Kirito and Asuna's future. His voice somehow makes me ring my "he's dangerous" bell...:P
While the health bar missing could be considered a small glitch inside the system, this scene right at the end of the episode was clearly weird.
Yui was able to influence other people with some kind of supernatural ability. This isn't possible for any other player and give me more reasons for which I consider her part of the game.
Her words were also pretty self-explanatory "I was never here (starting city), I lived in the dark for a lot of time" leading me to think to the discarded AI situation.

Next episode will make light over Yui's true identity and will probably give us even more insights about why the system generated such an anomaly.
However, if she ends up being an AI, she is at risk being deleted by the administrator of the game system (that creepy red game master).
I believe she will make through the story though (maybe reappearing in future arcs), because this series is somewhat missing a mascot character...:P

Concluding, Sword Art Online continues to be an entertaining experience that I'll be sure to continue to cover every week in this blog.
See you soon,
