The group NMIXX held their first world tour, "EPISODE 1: ZERO FRONTIER," over two days on the 29th and 30th at the Inspire Arena in Incheon. This concert marked the first journey of NMIXX and their fandom, NSWER, signaling the beginning of a new exploration into the unknown world.

The performance began with their debut song "O.O." It was followed by "Love Me Like This," the group's first song to enter the top 10 on the Melon Top 100 chart, "High Horse," which ranked 2nd on Billboard's "Best K-pop Songs of the First Half of 2025," and the new track "Blue Valentine." NMIXX showcased a diverse set of about 27 songs in a band live format.

Notably, songs such as "Shape of Love," "Red light sign, but we go," "Slingshot," "Reality Hurts," and "ADORE U" were revealed for the first time during this world tour. Through this concert, NMIXX demonstrated the true value of their signature genre, "MIXX POP." The setlist was not just a simple lineup of songs but contained a narrative of transcending the "limits of reality" (ZERO) and moving toward a new world ("FRONTIER").

Despite intense choreography, NMIXX proved their powerful vocal range and singing ability throughout the performance. The members freely executed ad-libs, proving their skills as a talented group. Lily said, "It has been nearly four years since our debut, and thanks to NSWER's endless support, we have gained a lot of strength. I hope you will stay by our side forever." Haewon stated, "I will work hard to become a singer you can be proud of without feeling embarrassed."

Seol Yoon mentioned, "I wanted to show a better stage, but I feel regretful because I made many mistakes," and Bae said, "The love exchanged between fans and singers is hard to express in words. So, I am truly grateful." Jiwoo expressed, "Thank you for allowing us to hold our first concert on such a big stage," while Gyujin said, "This concert was my goal and dream, and I am thankful that it has become a reality."

Through "ZERO FRONTIER," NMIXX proved that their work is not just a genre experiment called "mix pop," but an art form with solid storytelling. They strengthened communication with their fans through their music and raised anticipation for their future journey.

Before the concert began, the venue was filled with a mysterious atmosphere. The six members appeared on stage with intense band sounds, continuing their interaction with fans. During the concert, they also took time to share their feelings with each other. Gyujin explained, "The concert title represents the first journey of NMIXX and NSWER together and the beginning of a new exploration into the unknown world."

NMIXX offered fans a special experience through this concert and established their musical identity. They pledged, "We will go further so that you can be proud of us."

Finally, as the concert ended, NMIXX cherished the precious moments with their fans. They confessed, "We were very nervous since it was our first concert, but thanks to you, we were able to do well," and promised, "We will complete the tour in good health and come back again." This world tour became an important milestone that elevated NMIXX's musical journey to a new level.
