The planet Libertia was once known as “the planet of death”, until humanity built three giant mirrors and created what seemed like an ideal land. It is on this planet that Professor Grace and his granddaughter Alcia live peacefully… until their home is attacked by Guild soldiers looking for the professor and for Legaciam – a special Armor that can resist extreme heat, allowing it to go to areas where humans would not survive normally. Alcia, who was at the time piloting Legaciam in order to help her grandfather with the testing, manages to get away… barely. But the Guild is determined to get Legaciam by any means necessary…

The evil overlord Makuamuge is planning to take over both the game and real worlds, and it is up to the ninja Goemon, his friends, girlfriend, and giant robot to defeat Makuamuge's henchmen and save both worlds.

Everybody goes to the ocean for a summer festival and the guys sneak off to a cursed island.

Second movie sequel of Wake Up, Girls!.
