∞! (Hatchi)
하치
The Japan DIMENSION. Rotational — not a permanent eight. Mayu (S16) and ShiOn (S20) were pre-selected by MODHAUS; Gravity filled the other six with 968,420 COMO in July 2024. Current Hatchi: JiWoo, ChaeYeon, YooYeon, SooMin, Kotone, Mayu (leader), ShiOn, ChaeWon. Untitled (2024) then SecretHimitsuBimil / Password (2025) on SME Records. Hatchi = 8. The next Japan season is expected to re-Gravity the eight (pre-selects may stay) toward a 2027 Japanese full album; this lineup is the exclusive Japan-facing DIMENSION of the current clock, not a side project.

Gravity
Mayu (S16) and ShiOn (S20) pre-selected. Gravity filled six more with 968,420 COMO (July 2024). Rotational Japan eight.
∞! · 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.
An eight that can be recast without breaking Japan.

Ballad Dimension 2
CREAM 02. JooBin (S18) is pre-selected — the Hatchi method applied to a vocal DIMENSION. Gravity fills the rest. Aria (2024) was the first quiet five; this is the second.
