Story

Leone and her Invader tank are back on Earth to partake in a rescue operation. Percier is still suspicious of Leone since she is only staying with the Martians until they can remove the Invaders from her tank. Nonetheless, she tells her that the Invaders on her tank have sensed another of their kind calling for help from a top-secret underwater base, along with a treasure of sorts.

In the base, Dion, Romy and Katalina are aware of the arrival of another Invader and state that they'll destroy the base if they have to if it means the Invaders won't cause havoc outside. Leone and her tank soon enter the base, freeing the mysterious Invader, a sea angel-like creature. She soon runs into the three ACE officers and is surprised to see them at the base. Likewise, Dion returns the same as he had not expected her to return after hearing of her declaration. Leone states that she came as she believed the Invaders would leave if she went with them, but Dion tells her that the Invaders are hostile and they'll have to fight.

At the first location, Leone encounters Katalina. Katalina asks why she has betrayed the Rebel Army, but Leone is unable to give an answer at first. She then states that the parasitic Invaders are preventing her from doing so.

At the second location, the mysterious Invader runs into Romy, who takes note of its appearance and grabs a piece of paper, placing it on the Invader before taking it out. She then realizes that the Invader's properties would help maintain her cuticles and decides to send a sample to Navy if possible.

At the third location, Leone encounters Dion, who tries to woo the parasitic Invader into joining the Rebel Army. The Invader's eyes turn red, and Leone warns Dion that it means it's prepared for battle, much to Dion's surprise as he thought it was working.

The mysterious Invader continues to battle the ACE officers, as the base begins flooding with seawater. Leone asks it to stop as it has gotten the "treasure" it sought, which it trembles upon doing so and she interprets it as it agreeing with her. Leone asks Percier to pick them up, and not wishing to leave her seniors to die, has her Invader stick them in a mass of goop to bring with her too. Romy unexpectedly finds the goop to be good for her hair. Percier asks Leone where the mysterious Invader is just as it emerges from the water and lunges towards them.
