Mouse

Muon Sorata appears to be an ordinary college student.

However, he has a secret identity, that of the mysterious thief called Mouse.

He is intelligent, wealthy, powerful and influential.

Stealing only the most valuable objects, he is supported by three beautiful female subordinates, who are indentured to the house Muon: Momozono Mei, a computer and physics expert; Kuribayashi Yayoi, a chemistry expert; and Kakio Hazuki, an agile fighter, good at combat and sports.

Nothing is safe from Mouse and his team of professionals... or is it?
