(Confused) Log out..? What does that mean?

(Sad) She was my childhood friend. She was the same age as me. When we were little we played together all the time and after I received my calling she would bring my lunch every day without fail, but then... (Angry/sad) Because of me the two of us went to explore a cave up north and by accident she crossed the boundary into the dark territory. A place no human is allowed to enter, ever, the taboo index forbids it. (Sad) The next day and integrity night came to our village and he took her to centoria to be executed... (Somewhat hopeful) But I still belive she's alive Kirito, I just know it.
