BABYMONSTER has released their debut Japanese original song, "Ghost."

The track serves as the primary theme tune for the upcoming live-action movie 'Mieruko-Chan.' BABYMONSTER infused their unique hip-hop style into the melody, blending their singing prowess with impactful rap verses.

In parallel, 'Mieruko-Chan,' inspired by a manga series, portrays the story of Miko Yotsuya, a high school student with the ability to perceive ghosts and apparitions. She strives to navigate daily challenges while encountering these terrifying spirits that inhabit her world and the lives of those around her.

The live-action adaptation of 'Mieruko-Chan' is scheduled to debut in Japan on June 6.
