Synopsis
At the Sand Leaf beach, the battle against the Sahuagin continues. The trainers form a pick-up group, talking to each other about their abilities as they fight. Kawara uses Tiger Echo Fist on several Sahuagin and Shigeru asks her how long it would take before she could cast it again after bemoaning that he couldn't aggro all the Sahuagin in the area. Shoryu and the other trainers go back to back as they become surrounded by Sahuagin, hoping to delay the monsters long enough for Maryelle and the low-level players to escape to the school.

At Ragranda Forest.The camp begins encountering goblins inland while Nyanta discovers a massive goblin army approaching from the north. After pooling their knowledge, Naotsugu informs Shiroe who organizes an emergency relay conference with the Round Table. Shiroe postulates that the recent attacks are part of a quest known as "Goblin King's Return". The Adventurers then realize that they neglected quests from the People to defeat the goblins in their development of Akihabara which in turn caused the Goblin King to unite a great army. At the same time, Raynesia 's father leaves to defend the town of Maihama from a goblin invasion. Afterwards, the training camp discovers a goblin raiding force marching towards the nearby town of Choushi. Meanwhile Shiroe summons Soujirou and the West Wind Brigade to the Ancient Palace of Eternal Ice to aid in its defense should it come under attack. Shiroe then informs the Round Table Representatives of his hypothesis that an in-game death induces memory loss, which Crusty verifies and shockingly reveals that he had already lost some memories of the real world. Elsewhere, the training camp makes their way to the Choushi town but they end up arriving too late. However, Minori decides that the Adventurers shouldn't wait for the People to ask for their aid, and instead, attack the goblins themselves.
