3✓ WatchedMemories of BloodIn real life, the player Sinon is a high school student named Shino Asada. On her way home from school, she’s dragged into an alley by delinquent girls. Their leader, Endo, tries to extort money from Shino, but she bravely refuses.
4✓ WatchedGGO (Gun Gale Online)Kikuoka has recruited Kirito to investigate GGO, and so he logs in. To lure Death Gun into targeting him, he hopes to enter Bullet of Bullets (BoB), a tournament to decide the most powerful gunman in GGO. But as a first-timer, he doesn't know his way around this game, and soon loses his way, when he catches sight of Sinon and approaches her.
5✓ WatchedGuns and SwordsTo register for BoB, Kirito starts entering the required information into a terminal, but is astounded to see that the form includes columns for his real-world name and address. He is temporarily torn when he realizes that without this info, he won't be eligible for the top prizes...

He uses the remaining time to exchange information with Sinon and find out more about the contestants. Sinon sees how strange he was acting during the qualifier and asks him what happened.

Death Gun is skilled with not only a gun but a blade as well, and he gradually wears down Kirito's health.
