Member
Pure, Sense 43. Robocosan placed 80th as a member (−21,871 EV). Initial Koyori and Swimsuit Marine can raise Sense on a Pure core. Her mixed outfit and yellow solo-song Connect are the stronger reasons to pick her up.
Robocosan’s longer Active adds less across a song than Autumn Pekora’s in the sampled teams. Her Passive supports Active scoring, so her distinctive member role is combining a long scoring window with activation assistance from her Special.
The Active upgrades at bloom 1, the Special at bloom 3, and the Passive at bloom 4.
Active
Her Active checks every 33 seconds at medium probability for 12 seconds. It goes from 50% to 60%, or 100% to 120% with two Pure members. Swimsuit Marine has a similar 34-second, medium-probability, 12-second, 120% profile, so their long windows can overlap. Autumn Pekora’s 25-second checks spread out the timing and her scoring Active can use Robocosan’s Passive.
Passive
The Passive grants two Pure members 8% to 11% score support. It boosts their successful scoring Actives, while Initial Koyori’s 43% Sense Passive raises team power.
Special
Robocosan’s unconditional Special gives 100% to 120% score support and 35% to 40% activation rate for 12 seconds. The Pure requirement belongs to the stronger Active effect.
Leader outfit
The outfit gives the team 80% Sense and 25% score support with two Pure members. It ranked 33rd on non-vocalist songs (+24,400 EV). Swimsuit Marine has an equivalent, while Initial Kanade and Autumn Pekora offer 130% Sense with the same requirement. On the release EXPERT chart for “slight fever,” the best formation found with Initial Robocosan’s outfit scored higher than the best one using her autumn outfit.
Connect
The six-tile right convex shape goes from 110% to 160%. Place it inward in the yellow slot left of center for +2.75% to +4.00% solo song bonus. A low-bloom right line from center gives +3.15%. The yellow convex placement leaves the center free. Initial Subaru and Swimsuit Flare have exact substitutes. Consider extra bloom if you have no equivalent and room below the 10% song cap.
