By Shiroe's suggestion, Rayneshia decides to take a leave from her duties in the New Round Table and travel to the Chinese server by boat to help bring Crusty and the others back home. Meanwhile, Minori and her friends befriend the sisters Lelia and Litka Mofur and decide to shelter them at Log Horizon's guild base. Shiroe, Nyanta and Tetra recognize Lelia and Litka as two old questgiver characters from Elder Tale's early days who are known for being clumsy and troublemaking, having doubts about having them around until the sisters reveal that they are following the trail of an unknown monster called Ereinus, which makes them deduce that a Genius is about to attack the city.
