01 · Arrival
S18 Joo Bin is the 2009 visual. Revealed the day after Lynn as NXT's second SIGNAL, she is among the youngest Koreans in the group — conifer green, ISFJ, later Zenith, and the one member MODHAUS pre-selected for Ballad Dimension 2 in 2026. Quiet face, tall frame (168 cm), maknae-line gravity. The Hatchi method applied to a vocal DIMENSION: lock one body, Gravity fills the rest.
02 · On stage
Conifer green, ISFJ, NXT then Zenith. Second-youngest Korean. Visual as a still, not a stunt.

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.
