Swimsuit Koyori review

Happy type, Per40 distribution. A useful Per formation core because its Passive raises two eligible members. An eligible partner lets it increase both members' Total Power. Secure that supported pair before filling the remaining slots.
Member
There are 10 eligible five-star partners sharing its main parameter, including Initial Shiori (32s) / Initial Matsuri (23s) / Swimsuit Kanade (23s). Parentheses show unaccelerated Active intervals. The card itself counts toward type/group requirements; variants of the same Holomem cannot be deployed together. Swimsuit Kanade can return a useful parameter buff. With effects limited to two recipients, check allocation when adding more eligible members.
The Active checks every 25s and lasts 9s. Its bloom1 baseline is standard among five-stars with the same activation probability. The stronger effect needs Life ≥ 600; without it the low-bloom boost falls to 50%.
The Special is a standard support-focused design. It has no activation assistance, so blue Board effects or another Special can supply that role.
Outfit
All members Score Support 60%
A dedicated Active score-support outfit with no parameter increase. Parameter outfits are the more useful starting point during development, making outfit-only acquisition a low priority. Compare it against parameter outfits in a developed Board setup. Same-condition/effect examples: Initial Kronii / Initial Kaela / Initial Reine。
Connect and development
Down cross 5:150%→200%
Use it as a Down Line3 substitute from the center toward green or in yellow for group songs. Yellow gives +1.50% at low bloom and +2.00% at bloom5, below low-bloom five-star Down Line3 (+2.20%) and bloom5 four-star (+2.15%). Allocate Down Line3 first, then fill uncovered Boards.
