After struggling to survive in a surreal existence they were suddenly thrown into, Shiroe and his friends have managed to restore order to Akihabara. After six months with the team gaining the trust of the many guilds that use the city as their base, they must now prepare for a tough winter ahead. Whatever they may decide, this world that was once a game for the players is now reality and they must decide what is best for each and every one of the members of the team.
The grandest treasures lie at the very bottom of every dungeon. Shiroe finally reaches the lowest level of the Abyssal Shaft and comes face to face with Uru of the Ninth Garden, keeper of the massive gold reserves of the Kunie Clan.
