Dare to Log On? (SAO Fanfiction)

(WARNING: POSSIBLE SPOILERS)
Tetsuo has gotten stuck in a virtual game called "Sword Art Online". The game is accessed using nerve gear, which sends electrical waves through the nerves in the brain to give the illusion of being inside a video game. The creator/developer of the game has set it to where you cannot log out of the game nor can you leave. If the nerve gear if taken off of you, you will die and if you die in the game then you will die in real life too. The only way out of the game is to beat it. Tetsuo is one of the many people trapped in the online game. His family is devastated and worried, especially his sister, Sakia. When Sakia finds out that her beloved brother has been trapped in Sword Art Online, she decides to go in after him and protect him. It is what little sister should do anyways. Will the two make it out of the game alive?
