New song "CYM" written by Billyrrom has been decided to be the theme song for the drama "MADDER".

It has been announced that Billyrrom will be in charge of the theme song for the Kansai TV x FOD drama “MADDER: I am the Certain”, which will be broadcast late at night on Thursdays on Kansai TV and Fuji TV, which will begin airing on Thursdays on April 10th.

This drama starring Ihojo Mao (Nogizaka46) is a mystery entertainment that leads in a genius high school student with a standard deviation of over 78, Nakano Akane (Gojo Mao, Nogizaka46), meets Kurokawa Yu (Yamamura Ryuta, flumpool), a young man who is believed to be the perpetrator of a murder case, and then causes a small incident at school, which eventually leads to a serial murder case that will shock Japan. This work will be his first appearance on a terrestrial TV drama series and his first lead role.

The new song “CYM” that Billyrrom will be released on Wednesday, March 26th will be used as the theme song for the drama. Inspired by the drama, the theme is “the color change of emotions due to the differences between oneself and others, and the struggle to understand them,” and as the title suggests, the song is a song with the initials of three primary colors, cyan, yellow, and magenta.

Rin (Gt.), who wrote the lyrics, said: “Since the title is related to color, I used the keyword to “color” and used it to show how Akane’s emotions move, and explored the words that were satisfying.” Mol (Vo.) also commented, “The sound of the song really gave me the distinctive features of Billyrrom, and I was able to work on the production with a relaxed attitude.”

You can hear some of the theme songs in the special video released today.
