the story takes place in the theater of dominance, after Raiden Mei, the Herrscher of Thunder, has been captured and assimilated into a herrscher of dominance puppets

Herrscher of Dominance: Now~ my dearest mei~ I have a mission for you~ Go get your dearest Captain for me~ Bring him here so we can turn him into one of us too~

Mei: Of course~ my mistress~ he won't be able to resist us~

Shortly after, Mei arrives in your ship, Hyperion. You greeted her but saw her now wears a black eye mask with golden trims, a herrscher of dominance symbol on her forehead, and wearing black and gold puppet suit and gloves

Mei: Hello captain~
