Crisis befalls the main characters and the Earth as well! How do they deal with the conspiracies that they have uncovered, while protecting the Earth too? (And what happens to the cliffhanger at the end of the previous episode?) In these final two episodes of Stratos 4 Advance are the exciting conclusion to the whole Stratos 4 series. The main characters will have to draw on all the resources they have, their friends and allies and their own sheer force of will, to "bring tomorrow to Earth," as one of the characters puts it.

Two advanced civilizations, the Paranoids (a race of alien humanoids) and the Solenoids (who are all women) are waging a war that has gone on for centuries. When the Solenoid fleet leaves a battle to defend an experimentally terraformed world from the Paranoids, one damaged Solenoid ship, the Star Leaf, is separated from the fleet. Only seven women remain alive on the ship: Eluza, the captain, Rabby, the solid more or less main character, Lufy, the brash pilot, Catty, the mysterious science officer, Pony, the pink-haired ditzy tech, Patty, a solid crew member, and Remy, the cute one. After narrowly escaping the battle, the crew of the Star Leaf decides to continue with their orders and rendezvous at planet Chaos to defend it. It turns out, however, that their ship is the subject of a Paranoid experiment. In the end, it is up to the remaining crew Star Leaf to defend the artificial paradise of Chaos from the Paranoid fleet and the plans of the Solenoid leaders.

Stratos 4 Recap episode - For everything which happened before Stratos 4 Advance started.

After her boyfriend breaks up with her for another girl, college student Akane Kinoshita wrestles with a broken heart and the memories he left behind. Loading up Forest of Savior, the MMO they used to play together, she forms a plan to get back at her ex-boyfriend through an in-person event for the game. In the process, she runs into someone unexpected: Akito Yamada, a gaming legend who just happens to be her guildmate. Desperate for support, Akane ropes the asocial Yamada into helping with her scheme and lending her a shoulder to cry on. The differences between Akane and Yamada soon become apparent as they spend time together, yet they cannot help but notice each other's inner qualities. As the two gain more experience with one another in and out of the game, their tentative acquaintance may level up in a way neither expects.
