In the ruins of Shelter Edesia, alien machines unleashing fireballs appear. The unfamiliar attack puts Yamato and his friends at a severe disadvantage. Then there's Arshem, who's working together with Victor. She forges bonds with the indomitable Terrans living on the surface who refuse to give up on life even as the Red Ochre Fever sickens them. Once more, she feels the weight of the sins perpetrated by her people against another planet.
Remember those Wurms that attacked us? 
We harvest the medicine from them.
Es haben uns doch Würmer angegriffen.
Wir ernten die Medizin von ihnen.
¿Recuerdas los gusanos que nos
atacaron? La extraemos de ellos.
Tu te souviens des vers
qui nous ont attaqués ?
Ricordi quei Wurm che ci hanno attaccato?
