How she was batched

• Two Big WAVes

  LOVE spelled backwards is EVOL.

  Universe 2 split the growing roster into a love-side eight and a harder eight. SeoYeon kept the captaincy through MUHAN and the Authentic US tour. YooYeon took EVOL through MUJUK and Australia. Girls’ Capitalism vs Invincible is not a rivalry chart — it is a palindrome. The content team ran two touring DIMENSIONs at once: two HAUS temperatures, two title-track bodies, one fandom name. That is the first time 24 started to feel like a system instead of a countdown.

• 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.

• ∞! · Japan eight

  Rotational, not ‘the Japanese members’.

  Hatchi is 8. Mayu and ShiOn were pre-selected; Gravity filled six. Two of four Japanese members are in the current eight — Kaede and Lynn are on other planets this season. That is the rotation working, not an exclusion. Untitled then Password. The next Japan season is expected to re-Gravity the eight.
