Their suspicions aroused, Illya and the others race to the scene, where they encounter two mysterious women who say they've come to retrieve Miyu... After a fierce battle, they're all bathed in a mysterious light. Afterwards, Illya wakes up to a midwinter Fuyuki City?!
Illya-san's my precious to— master, after all.
Schließlich ist sie mein liebstes Spiel…
meine Meisterin, mein ich!
¡Illya-san es mi querido jugu… maestra!
¡Illya-san es mi querido jugu… maestra!
