SEITA of NEXZ: Member Profile, Career and 2026 Guide
Seita performs with an unusually calm center. He can hold an eye line without freezing the phrase, and that restraint gives the group a necessary pocket of stillness when the production becomes busy.
BLUF: where SEITA stands now
SEITA is a current NEXZ member, active from the group’s May 20, 2024 global debut through the current seven-member lineup. There is no verified independent solo release under this name as of August 2026, so CVM Sekai files this as one member profile rather than creating a duplicate Artist page.

The Nizi Project Season 2 chapter
His pre-debut modeling experience helps explain camera awareness, but it does not explain the musical growth. Nizi Project Season 2 and the debut years show him learning when a visual beat supports rhythm and when it becomes decoration. The competition record should be used as chronology, not a permanent personality test. Evaluation footage shows trainees under a format designed to produce stakes; it does not grant access to their private thoughts.

From Miracle to the global debut
The seven finalists released “Miracle” in Japanese and Korean on December 18, 2023, linking the final stage to the group’s first public catalog. NEXZ then made its global debut on May 20, 2024 with Ride the Vibe. The song’s elastic rhythm and youthful uncertainty established a lane that valued physical timing as much as conventional polish.

The Japanese debut and Keep on Moving
The August 2024 Japanese EP paired “Ride the Vibe (Japanese Ver.)” with “Keep on Moving.” The latter is not just a cheerful extra: its Korean-version performance film tests stamina, bounce and ensemble clarity. SEITA can be tracked through the whole frame instead of only the assigned close-up.

NALLINA and the first Korean expansion
NALLINA arrived in November 2024 with heavier percussion and a more mischievous performance vocabulary. That shift matters for SEITA because it asks for character without allowing synchronization to dissolve into seven separate skits. The best stages preserve both the joke and the geometry.

O-RLY?, One Bite and touring scale
The 2025 catalog expanded through O-RLY? and the Japanese EP One Bite. The first national Japanese tour covered eighteen performances in fifteen cities and passed 50,000 attendees according to the official profile. A tour tests whether a three-minute television identity can survive pacing, repeated performances and a room that cannot rely on camera editing.

The 2026 checkpoint
The Budokan concert recording reached number one on Oricon’s weekly music DVD and Blu-ray ranking in February 2026. Mmchk followed on April 27 and gave NEXZ its first Show Champion win on May 6. Hellmate then connected the year’s Korean and Japanese activity while the 2026 arena tour raised the scale again.

Performance signature
Seita performs with an unusually calm center. He can hold an eye line without freezing the phrase, and that restraint gives the group a necessary pocket of stillness when the production becomes busy. Watch the counts before and after the obvious highlight. That is where performers reveal whether a center moment belongs to the song or exists only as a clipped social-media fragment.

Voice, rap and arrangement function
NEXZ does not publish a rigid current list of permanent main and lead positions. That is useful. Instead of turning fan shorthand into fact, listen for what changes when SEITA enters: register, rhythmic pressure, vocal brightness, physical weight or the emotional temperature of the frame.

Dance, formation and camera work
Clean choreography is the baseline, not the whole verdict. The more revealing details are travel paths, recovery after a large accent, the finish of a hand when the camera is elsewhere and the ability to scale expression for a wide shot. SEITA should be evaluated across all of those conditions.

Why this is not an Artist profile
A fan-club member edition, individual fancam or profile film is not a solo music debut. CVM Sekai routes a member into Artists only after a verified independent release. Group songs remain on this page as career evidence, while the NEXZ hub owns the shared discography and release tracker.

How international fans can follow closely

The visibility gap outside Korea
NEXZ works across Korean and Japanese systems, which means information is split across sites, languages, physical-release notices, music-show uploads and tour pages. Overseas fans are not failing because they missed one rumor account; the publicity trail is genuinely fragmented. A good hub reunites it without pretending every schedule is global.

What quick profiles usually miss
Birthday lists and one-word positions cannot explain why a performer matters. They also age badly. This page keeps dates, current status and release evidence separate from observations about technique so an official update can change the facts without rewriting the entire person into a new stereotype.

RaeRae verdict
Seita performs with an unusually calm center. He can hold an eye line without freezing the phrase, and that restraint gives the group a necessary pocket of stillness when the production becomes busy. That is specific enough to test against another stage, and it leaves room for the answer to change. Praise should point to a choice. Criticism should name a tradeoff. Private-character claims should stay out unless the member has actually said the thing being attributed to them.

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.
