Thanks to his father's sudden remarriage, Tojo Basara finds himself with two beautiful new step-sisters. Their names are Naruse Mio and Maria. Mio wakes him up in the morning, while Maria stands in the kitchen wearing a suggestive outfit...
So you're demons, and Mio is the Demon Lord?
Also seid ihr Dämonen
und Mio ist die Dämonenkönigin?
¿Ustedes son demonios y Mio es su reina?
¿Ambas sois demonios y Mio es vuestra reina?
Vous êtes des démons
Quindi siete demoni 
e Mio è la Signora dei Demoni?
Então vocês são demônios e a
 Mio é a Senhora das Trevas?
Хочешь сказать, что ты демон, 
а Мио — Повелительница демонов?
