There's a new special mission involving the usual Yatagarasu members, but Gai, Kei, and Nayuta are kept in the dark. The members go out of their way to keep this mission top-secret, but will they be able to keep the AIs out of the loop for long?
So what, they don't need us anymore...?
Wir sind also längst überflüssig?
Ils n’ont plus besoin de nous,
c’est ça ?
Quindi cosa vuol dire, 
che non hanno più bisogno di noi?
