Full Moon - A la recherche de la pleine lune s01e26
Titre original : My Message
Wakaoji tells Mitsuki to think about what kind of message she wants to send when she's going to sing "Eternal Snow." So, Mitsuki, Takuto, and Meroko rummage through the Kouyama family's old things to see what kind of message Mitsuki's father wanted to send. They then find a jeweled music box that plays the "Eternal Snow" melody.
