Эпизод 6

Rena goes missing during the battle with the monsters, so Shu-go and the others look for her. Just then an anonymous e-mail arrives, its sole contents being a certain Area of the game. Shu-go and the others think that perhaps Rena's disappearance is simply an ""event"" bulit into the game. They head to the Area named in the e-mail to check it out.
