There is But One Ultimate Way
In summer time of year 2026, while three of the alliance member - Leafa, Lisbeth and Sinon drinking tea in ALO, which they're all sad because Lisbeth is ending her last high school summer holiday and will end a stage in her life, and with the feeling shared by Sinon as she intended to get a job. While Leafa satisfied with just being by onii-chan's side, it is afraid that one day it would even be difficult by just staying in Kirito's side when he have to go for further education or get a job and slowly leave their small circle, as well as go less often onto ALO. It made girls think of the gradually changing environment that finally might even let this feeling would disappear and start crying.

Then Alice raise the idea that there aren't just one real world and Underworld is also a real world, then bowed and begged Asuna to let everyone create dazzling memories that last a lifetime remain with them even in the real world. Thus lead to events in There is But One Ultimate Way.
