Cure Black 03

In Futari wa Pretty Cure Max Heart: Yukisora no Tomodachi, when Cure Black and Cure White give all of their strength to protect Hinata from Frozen and Freezen, they do not have enough energy left to fight, and in their last try to keep the two villains away from their friends, they freeze the girls. Hinata, touched that it is possible to care so much for a friend, awakens from her icicle and sends her warmth to Pretty Cure, melting the ice and giving them a new power.

Cure Black's hair gets longer and slightly wilder, and feathers are hanging after her skirt and shoulders. Her bow has also changed to a golden color. She also gets boosted powers, as she easily manages to fight Frozen with closed eyes without getting hit once. It also seems like their minds are much calmer in this form, as neither of the girls do anything rash or fast; they just dodge and wait for the final strike.

Scan picture and extract the character by me.
