Mooncake Festival (TW)
Mooncake Festival Event is an annual event that happens every Mid-Autumn (Mid-August)

Lilio's Mid-Autumn Lesson! (TW)
During the duration of the event, Lilio does not understand what Mid-Autumn Festival is all about. Help her by giving her a 'Mid-Autumn Encyclopedia', an item randomly found after any GAT match or Megaforce mission.

When she receives one of said item, there is a roulette from her store. A random item will be given to you out of 25 possible prizes of each, mostly themed to the event.

Other Encyclopedia can be used, but it costs 2 books instead of 1 to use. In this case, its better to use the themed books instead.

This also applies to items like Halloween Marshmallows, but instead of costing 2 of each, it will cost 4 of each to use.
