They appeared on KBS2's "Music Bank" on Dec. 13, MBC's "Show Music Core" on Dec. 14 and SBS' "Inkigayo" on Dec. 15 to give them a comeback stage where they can get a glimpse of the colorful military dance.

Stray Kids released their mini-album "Clé: LEVANTER" and their title track "Levanter" on Dec. 9.

The song is written and composed by the team's production group 3RACHA and JYP Entertainment's chief producers Park Jin-young and Herz Analog participated in the lyrics, which contained their desperate wishes for their dreams.

In the music video for the new song, Stray Kids caught the eye by presenting a beautiful dance line against the backdrop of a reed bed. Following FELIX's powerful solo dance, the team has completed an energetic performance with a sword dance that matches the steps.

They then posted a practice video on the official SNS channel on Dec. 11 afternoon containing a full version of the choreography for their new song "Levanter."

The dance, in which the two members are symmetrical, has redoubled their expectations for the stage of the show with perfect breathing, as if looking at a mirror.

Meanwhile, the new song 'Clé: LEVANTER' is leading the global craze at the same time as it is released.

As of 1 a.m. on Dec. 10, it topped the iTunes album chart in 17 regions around the world, including Brazil, Norway, Sweden and Turkey, realizing the popularity of Stray Kids.

Stray Kids will start with the U.S. in January next year and hold the world tour "Stray Kids World Tour "District 9: Unlock."
