Before NEXZ
SEITA entered as a JYP trainee from Saitama. His public audition profile listed lyric writing among his interests, alongside anime and rhythm games. He had training experience but did not receive an easy ranking because of it.
Nizi Project Season 2
SEITA finished eleventh in the Japanese camp and seventh in the final. His selection came after a show in which the available debut places stayed uncertain until the last announcement.
NEXZ Career
NEXZ released the Japanese and Korean versions of “Miracle” on December 18, 2023, three days after the final lineup was announced. The song had been used for the final stage, so the first release connected the survival-show ending directly to the group.
The official Korean debut came on May 20, 2024 with Ride the Vibe. The group followed it with the Japanese EP Ride the Vibe (Japanese Ver.) / Keep on Moving, the Korean mini albums NALLINA and O-RLY?, and the Japanese EP One Bite. Later releases included Beat-Boxer and the group’s continuing Korean and Japanese catalog.
Their first Japanese national tour, NEXZ LIVE TOUR 2025 “One Bite,” ran for eighteen shows in fifteen cities and drew more than 50,000 people according to Sony Music Japan. The tour placed the seven members in a full concert structure rather than a short rookie showcase.
Performance File
SEITA often reads clearly in close shots because he changes expression without interrupting the choreography. His line delivery is lighter than the group’s lower voices, which helps NEXZ avoid stacking the same tone across a verse.
NEXZ does not publish a rigid list of permanent main and lead positions on its current official profile. This page follows the work visible in releases and performances instead of turning a fan-assigned position into an official fact.
Where to Start
- “Miracle”: the final-show song and first pre-debut release.
- “Ride the Vibe”: the Korean debut and the first full introduction to the lineup.
- “O-RLY?”: a louder Korean comeback that gives the members more comic character.
- “One Bite”: the Japanese title track that became the identity of their first national tour. Read the CVM Sekai React.
