Outline of the ending theme "Migihidari
This song is written and composed by meiyo, a singer-songwriter who has provided music to many famous artists. It is an alternative pop tune with playful lyrics and phrases that make you want to hum along. Please enjoy this "quirky and cute" song that is full of pop and worldview, as if the characters have stepped out of the world of the work and started dancing.
Comment from Yuka Nagase
This is the first anime song I've sung in my life, and it was written by meiyo, who has been a great help to me for a long time. I am very happy.
The storyline is very heavy and there are many fierce battles, so I hope this song will be a place of relaxation for you and the characters, and be like a radio gymnastics for you.
Please put on your L and R earphones and enjoy the song!
▼ Comment from Mr. meiyo
The last boss of the "Nozui" student has appeared! I am meiyo, and I wrote the lyrics for the ED theme "Migi Hidari", sung by Yuka Nagase.
The song is sung by Yuka Nagase. I had the opportunity to write a song for her when I was an indie singer, and she sang it for me.
The director, Yuya Horiuchi, is actually a classmate of mine from high school. He was a member of my first copy band. We have been competing in our respective fields, but now we have met again in a way that fate has brought us together and completed the song "Migi Hidari", which is based on the motif of a certain character, with its enigmatic play on languages and unique floating sound. We hope you enjoy it.
