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?
We've stuck together like brother in arms,
but now you're tossing me aside?!
Nach all der Zeit zusammen
¡Estuvimos siempre juntos!
¡Hemos estado siempre juntos!
On a parcouru tout ce chemin ensemble,
et tu veux te débarrasser de moi ?
Siamo rimasti fianco a fianco, scontro dopo scontro, 
e ora vuoi gettarmi via come spazzatura?!
Мы ведь через всё прошли вместе!
