Girl group Crayon Pop and singer Kim Jang Hoon revealed still cuts from their promotion video of the song "Hero." The song was made for their collaboration Korean Firefighter Project.

The photo was released on the 29th. Crayon Pop is pictured wearing outfits similar to firefighter attire, and wearing flashing lights on their heads. They still look as youthful as ever with their bright facial expressions and cute outfits.

Kim Jang Hoon was also pictured wearing firefighter attire among the Crayon Pop members.

'Korean Firefighter Project' is an ongoing project by Crayon Pop and Kim Jang Hoon to cheer on and support firefighters who work in a harsh environment. "Hero" is this project's theme song, and sings of firefighters who go whenever and wherever they are needed. They are the true heros who often go unnoticed.

A Chrome Entertainment rep stated, "'Hero' is a great mix of Kim Jang Hoon's husky, powerful voice and Crayon Pop's cute and youthful voice. It also has easy choreography that is easy to follow, so we suspect that it'll be loved by many people."

The song is scheduled for release on February 5th, and all proceeds will be donated for scholarships, especially for firefighters and their families
