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?
I treasure Kei more than
anything in my life.
Du bist für mich kostbarer
als jeder Schatz.
Eres mi mayor tesoro.
Eres mi mayor tesoro.
Per me non esiste nulla 
di più importante di te.
Ты моё самое драгоценное сокровище.
