The Changing Battlefield

The Changing Battlefield is the ninth episode of the Log Horizon 2 anime and adapts the third chapter of Gold of the Kunie. It aired on November 29, 2014.

Summary
On Christmas Eve the Abyssal Shaft Raid Party come upon Ruseato of Seven Prison (Luseat of the Seventh Garden in the Crunchroll subs), a level 97 raid boss. After doing some recon, they engage the boss in battle. Shiroe predicts they have a fifty percent chance of success.

The first time the boss does an Area of Effect (AoE) attack there are two instant kills (Enkaatanto & Frederico) and three badly wounded (HighlandSky, Junzou & Ragoumaru). They revived the dead and healed the wounded while Sasameyuki kept count for the ability cool down time. Junzou and Ukiyo note that while that skill wasn't new, it was a lot more powerful than in The Nine Prisons of Heroes. He also has new moves which are equally as powerful.

Wiped Out
As the raid party slowly whittles down Ruseato's HP, they fail to notice the gates behind them slowly opening. Meanwhile, Demiqas furiously attacks Ruseato and the Shadow Vanguard, aiming to raise his levels, polish his skills, and win better equipment in order to defeat Shiroe. As Sasameyuki counts, a large shadow suddenly appears over him. Looking up, he barely manages a cry when Tarutauruga of Fourth Prison smashes him with its club, instantly killing him. As William mutters its name in shock, Ukiyo's scream drags their attention to Ibura Habura of Third Prison, which had appeared in front of the first party. The combined assault from 3 raid bosses wipes out the the entire party, as they curse the impossibility and unfairness of the raid.

After the raid party wipes out, Roe2 is seen rising out of the snow in a separate location.

Mare Tranquillitatis
Upon his death Shiroe is relieves memories of his lonely childhood back in the real world. Finding the resolution to move on, he is then transported to Mare Tranquillitatis which is a reproduction of the Moon. There he meets Akatsuki.

Trivia

 * When Shiroe looks at Dinkuron's status screen in one shot, the status screen is not properly mirrored, and faces us rather than him. This mistake is repeated multiple times in the episode.
