JYP Entertainment rookie group Xdinary Heroes (XH) will make its official debut today (December 6th) after releasing its debut digital single, "Happy Death Day."

JYP's artist label studio STUDIO J delivers a new stimulus to the music industry along with the boy band Xdinary Heroes, the second of its kind after DAY6. The Xdinary Heroes, led by drummer Gunil, a graduate of Berkeley College of Music, has solid vocal and performance skills in a total of six members, including bassist lead, keyboardist O.de, and guitarist Gaon and Jun Han.

They take their first steps in the music industry with their first digital single and title song, "Happy Death Day," and aim at Generation Z's tastes. The new song depicts a situation facing the cold truth on the happiest and most celebrated day. It is a song that satirizes the psychology of people with duality who are invited to a birthday party, laugh in front of them, and change their expressions when they turn around.
