羽のない背中に (Hane no Nai Senaka ni)

Background
"Hane no Nai Senaka ni" is an original song composed by TriadD Grid with Tohoku Zunko. It tells the story of three caterpillars (Tohoku Zunko, Yuzuki Yukari and ), who all become butterflies. However, the middle caterpillar does not grow wings when she comes out of her chrysallis, unlike her two friends. Devastated by her missing wings, the butterfly runs away from all her friends and dreams of one day becoming able to fly.

While she hides away, her friends are suddenly captured by a young boy, who collects butterflies and pins them to his wall. Among them are two young, twin butterflies ( and ), and a beautiful butterfly (Hatsune Miku) who have also been captured, and pinned to the wall. Discovering her friends are in danger, the wingless butterfly rushes to their aid courageously, using a pod of edamame beans and creating a magical bow and arrow. She shoots an arrow into the boy's room, its explosion blowing away the pins and freeing all of her captured friends. After saving all of them, the wingless butterfly comes to grips with her body, no longer feeling sorrowful about how she was made, and meets two others who are wingless, just like she is (Tohoku Itako and Tohoku Kiritan).

This song has entered the Hall of Fame.
