Sore Ike! Anpanman: Black Nose to Mahou no Uta

Kaana was once a tiny bird blown into the Forest of Darkness, where the queen Black Nose transformed her into a girl and raised her to believe that songs, dancing, delicious food, and laughter are false kinds of happiness. Sent into Anpanman's world with the Flute of Darkness, Kaana obeys and drains the joy from everyone who hears it.

Living among Anpanman and his friends exposes her to the very happiness she was taught to reject, and doubt begins to replace obedience. But by the time Kaana understands the deception, Black Nose has already plunged the world into darkness. To bring back the light, Kaana must choose whose teachings she truly believes and find the courage to sing with the friends she once harmed.
