Hibiki is badly shaken up after her meeting with her father.  She's so shaken up that even during the Autoscorer fight she can't focus properly, and Kirika and Shirabe have to protect her.
So have your fun, Micha.
لِذا استمتعي يا ميكا
Also hab deinen Spaß, Mika.
Así que, diviértete, Mika.
Así que, diviértete, Mika.
Alors vas-y, lâche tout, Micha.
Divertiti pure, Mika.
Por isso, divirta-se, Mika.
