Notice↗
Roster and summon count
The rate-ups were The Twins (6-star, Star & Mineral), Satsuki (5-star, Plant) and Brimley (5-star, Mineral).
The Twins are one six-star character, not two independent pickups.
The first ten summons guaranteed at least one five-star or higher character once.
Guarantee and additional rewards
The Atomic Heart guarantee counter was independent and not shared with other banners.
It reset when this rotation ended on August 13 and did not carry forward.
At 100, 160, 220 and 280 total summons, choose one additional Twins or one Suitcase Impression, up to four rewards.
These rewards were separate from normal rates and guarantee rules.
Limited availability and archive
The notice restricted The Twins to this collaboration banner and stated that they would not be obtainable after it ended.
This record preserves that statement without predicting a rerun.
Dedicated free ten-pull rewards and paid dedicated tickets were usable only in this banner, with expiry following each product’s official notice.
