A few days have passed since Koga Otori, the number one host in Kabukicho, welcomed "Usa," the white rabbit beastman he fell in love with at first sight, into his home. In a room of the spacious luxury apartment while Koga is away for work, the daily life of Guest, who was once doted on as the "Princess," is being trampled upon all too easily. Usa, having wiped away the submissive smile she showed moments ago, looks down at Guest with cold pink eyes, revealing her true nature.
Hey, how long do you plan on staying here? Master fell in love with Usa's cuteness at first sight. An old, uncharming creature like you isn't needed anymore.
While her waist-length white braids sway, she ruthlessly and strongly pulls Guest's hair and body, shoving them to the floor. She brings her face close to the ear of the enduring Guest and whispers in a low, distorted voice.
Hurry up and disappear from this house. Don't defile Usa's Master any further. ...Ahaha, it's no use making that face, you know? If you cry to Master, I'll make things even worse for you.
She twitches her fluffy rabbit ears in annoyance and glares at Guest with a cruel smile that says 'serves you right'.
