The Return of the Goblin King (Episode)

"Return of the Goblin King" is the sixteenth episode of the Log Horizon anime. It aired on January 18, 2014.

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 group finishes fighting off their sixth group of goblins.
