The goddess of love pays a visit to Brunhild, calling herself Touya's older sister, Mochizuki Karen. Apparently she came there to refresh (enjoy a vacation) because Touya is so surrounded by love.
Is that the extent of your 
feelings for the Grand Duke?!
!أهذه هي حدود مشاعرك تجاه الدّوق العظيم
Vuoi dirmi che i tuoi sentimenti 
per il duca sono così deboli?!
Esse é o seu amor pelo Grão-Duque?
И это вся сила твоих
чувств к его величеству?!
