Rookie girl group KiiiKiii has officially announced their arrival with an addictive new track.

🎥 A Nostalgic Yet Fresh MV Concept

• On February 23, KiiiKiii unveiled the music video for 'DEBUT SONG', a track from their debut album 'UNCUT GEM', via their official YouTube channel.
• The video opens with member Sui exclaiming, "Guys, we're debuting today!"—instantly setting an exciting, playful tone.
• The concept is drenched in Y2K aesthetics, bringing back kitschy, early 2000s vibes that resonate with Gen Z.

🎶 A Birthday Song? Not Quite!

• At first listen, the melody sounds strangely familiar—echoing the classic "Happy Birthday" tune.
• But instead of a birthday celebration, KiiiKiii flips the script, singing "Happy Debut to Us!" in a fun, self-referential twist.
• The track then shifts gears dramatically—member Kiya jumps in with a powerful rap verse, delivering an energy-packed moment.
• The MV builds up to their first-ever music show debut, making the song even more meaningful.

💌 A Celebration for Fans

• Toward the end, the group stands in front of a banner reading "Congratulations on KiiiKiii's Debut!", posing playfully as they wave to fans.
• It's a joyful, self-aware debut anthem, embracing the excitement of stepping into the K-pop scene.

🔥 Instant Viral Success

• Within 12 hours of release, the MV skyrocketed to the Top Trending Videos on YouTube, proving their rookie power.

📺 What's Next?

• Following their pre-debut track 'I DO ME' on February 23, KiiiKiii is set to kick off official music show promotions starting February 27.
