Kaichou wa Maid-sama!: Omake da yo!

After returning from Maid Latte, Misaki discovers that her maid uniform has been torn and asks her mother to mend it. Her younger sister Suzuna unexpectedly volunteers instead, repairing the damage so quickly that she becomes curious about trying the uniform on herself.

For Misaki, who works hard to keep her secret job hidden from school, that innocent curiosity is a looming disaster. Her frantic attempt to stop Suzuna from dressing up becomes even harder when unexpected visitors arrive at the Ayuzawa home.
