4-Piece Band BILLY BOO's New Song "Parallel Night" Selected as Theme Song for TV Drama 'Crossroad ~The Promise of Emergency Medicine~' Starring Mio Imada! Digital Release on July 8th!

BILLY BOO, a four-member band from Sendai formed in May 2024.

Their new song "Parallel Night" has been chosen as the theme song for the TV Asahi Tuesday 9 PM drama 'Crossroad ~The Promise of Emergency Medicine~'.

This work stars Mio Imada and is a "cross-medical drama" where young emergency doctors, paramedics, and police officers, torn between "burning ideals" and "unyielding reality," rise together and grow step by step to connect the "baton of life," intersecting with their fresh and passionate sense of justice.

The theme song "Parallel Night" is BILLY BOO's first drama theme song.

It is a song written specifically for the drama, an ultimate ballad delivered with a memorable melody and vocals, and a sound that exudes the essence of BILLY BOO.

There are as many "rights" as there are people, and the future changes as countless choices intersect.

"What if I had chosen a different path?" – A night of reflecting on the day with such doubts and regrets.

This song is a gentle light for everyone trying to move forward step by step, overcoming such nights.

▽ Comment from BILLY BOO / KAZUKI UJIIE (Vo)

Nights when you couldn't save someone you wanted to save.

Feelings that can't be conveyed by righteousness alone.

Moments when you feel like you're being swallowed by your own powerlessness.

Still, tomorrow comes again, and somewhere, a part of you is waiting for tomorrow.

Even if it's faint like a distant morning sun, you end up believing in that light.

When I read the script, I thought I wanted to depict not a grand hope, but rather the breath of a person trying to move forward even while crying. I would be happy if this song could be with each moment depicted in the drama, even just a little. And I hope it becomes a small light that makes you think, "Just one more step."

Additionally, a Pre-add / Pre-save campaign for the new song "Parallel Night" has been announced.
