After you name your character (you don’t have to go with the default) and customize your look, you start right in
Sword Art Online: Hollow Fragment. Provided you don’t change the name, your hero is Kirito. He finds himself facing a giant monster while he is battling a girl, Philia, who is almost as strong as himself. She will help you defeat the monster. This battle gives you a chance to learn the basics of fighting. Once you have the basics down, you find out that neither one really knows where they are located in the Sword Art Online (SOA) game. We do find out that Philia has an orange cursor because she once killed someone. Kirito’s hand gets some weird glowing symbol on it, so Philia teams up with him to take him to a place where she once saw that symbol. Since they’re lost anyway, it’s as good an option as any.
Once you do get into the sphere, you find it is your safe zone and you can use it to teleport to and from various places inside the Hollow Area, which is what Philia calls the strange place Kirito found himself in. You also find a normal teleport pad that will let you get back to Arc Sophia, which is your main base. Kirito heads back but Philia stays behind. When he gets back, all his friends (almost all of them happen to be female) are happy to see him as they were really worried! After all their scenes, you can choose to "recall" what happened in the previous game, which is quite helpful if you’re like me and didn’t play it. Basically, Sword Art Online is a fully virtual game where the players have all their senses connected. Unfortunately for the 10,000 players in the beta, they found out that there is NO option to logout, until Heathcliff (in real life Kayaba, the game developer) has been defeated.
Unfortunately, once that happened, the game still didn’t end. It has now been 2 years that they have been stuck in SAO, unable to log out, with no clue what is happening in the real world. Now they’re all stuck on floor 76. They can’t go any lower, so they must climb to floor 100. That brings us to the current time, which is where Kirito found the way into the hidden Hollow Area.
Back in Arc Sophia, you will get messages and requests from people in town. These are good things to do simply because they will help you on the quests. It turns out that Kirito is the only one who can access the Hollow Area and he can only bring one person with him, so each time you go back, you will need to figure out who to take. They all want to go, of course, because the more things that they find in the hidden area, the stronger they will become and the stronger items that they can find. They all want to become as strong as they can to get to the top floor, floor 100.
