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?

Oh, Nayuta, ¿por qué has de ser Nayuta?

Oh, Nayuta, Nayuta!

Ah, Nayuta! Por que és tu, Nayuta?
О, Наюта!
