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?
Don't they understand that
the more they hide, the harder we'll try?
Die begreifen wohl nicht,
Quels idiots ! Plus ils s’obstinent,
plus ça nous intrigue, c’est naturel !
Non lo sanno che più cercano di nascondere 
il segreto, più noi ci impegneremo a scoprirlo?
Eles não entendem!
Они не понимают психологию!
