Formalhaut has been assigned to assist Mira in the mission to subdue the magical girls. It's likely that this is also a form of surveillance from the evil king, who has heard rumors that Mira, the evil strategist, is inexplicably infatuated with a magical girl.
This must be the King of Evil’s
 way of keeping an eye on me.
‫لا بد أن هذه هي طريقة ملك الشر لمراقبتي.
Der dunkle Lord hat ihn sicher geschickt,
als er von den Gerüchten erfuhr.
Esto debe ser obra del Rey del Mal,
que quiere vigilarme.
Me juego el cuello a que esto es cosa
del Rey del Mal, que quiere vigilarme.
Il est peut-être un des observateurs
du roi du mal dont j’ai entendu parler.
Il Signore del Male deve aver pensato
 di tenermi d'occhio in questo modo.
O Rei do Mal deve ter sabido dos boatos,
e essa é a forma de ficar de olho em mim.
Видимо, таким способом Владыка Зла
решил меня испытать.
