01 · Arrival

S19 Jeong Ha-yeon is Zenith's captain. Anyang-born, she completed NXT's performance triangle on 23 December 2023 — the same day the unit dropped Just Do It — and two years later led one of msnz's four universe DIMENSIONs. Seafoam, ENTP, Leo. Chocoballs, hamster/hedgehog SIGNAL energy. This archive's WAV pick. The maknae-adjacent member who learned to lead a planet.

02 · On stage

Seafoam. Zenith is the highest point of msnz — HaYeon as the peak’s captain is the joke and the design. Bright green against a high-key stage.

03 · SIGNAL

How she was batched

  • Cream01 injection

    Four days. Four members. No Gravity.

    NXT (Lynn, JooBin, HaYeon, ShiOn) arrived in four consecutive December days and debuted the same week with Just Do It. Glow (ChaeWon, Sullin, SeoAh, JiYeon) closed the clock in April 2024. These batches were not voted — they were inserted so OT24 could exist on time. Team dynamic: the veterans had to make room in the HAUS footage overnight. SIGNAL’s job that month was introductions, not games.

  • msnz · four planets

    Moon, Sun, Neptune, Zenith — six each.

    WAV named the 2025 OT24 umbrella Magic Shine New Zone, then the roster split into four 6-member planets on one record, Beyond Beauty. Sullin’s Moon, Xinyu’s Sun (Bubble Gum Girl), SeoYeon’s Neptune, HaYeon’s Zenith. Team dynamic: four captains, four temperatures, monthly Japanese originals toward 2027. Sun is the aero-pop flag this archive had been skipping; the other three planets are the rest of the sky.
