Clutch! A Demon Incarnate, Robin!

Black Maria traps Robin's enlarged form in her web, and starts to sadistically beat Robin with her brass knuckles. Eventually, Robin cancels her technique, recreating her giant arms behind Black Maria. However, Black Maria is able to block the attack, burning the webs she used and surrounding Robin in the process. Black Maria begins swiping at Robin, forcing her to evade, until she ends up caught in one of Black Maria's webs. Black Maria states that she is only retaliating for Robin punching her earlier, and she hits Robin again, throwing her into another set of webs. As she continues to beat Robin, she berates her, stating that she is only useful as somebody who can read the Poneglyphs. Black Maria's insults remind Robin of her childhood and time on the run, and Brook advises Black Maria to run before it's too late as he creates an ice wall to prevent Black Maria's underlings from interfering. As Robin continues to think back, she remembers a training session with the Revolutionary Army, during which she learned a new palm-thrust technique that applies Fish-Man Karate techniques. She creates another giant arm and thrust the ceiling above her and crashing debris above Black Maria, putting out the fire in the process. Free from the webs, Robin creates another giant body, this one in the shape of a demon, Demonio Flur. She generates more arms, trapping Black Maria in a grappling hold and knocks her unconscious with Grand Jacuzzi Clutch. Hearing Black Maria's scream, her Gifters and Kunyun try to see through Brook's ice wall. They realize the Black Maria has lost, and while in a panic, are swiftly defeated by Brook. Brook then walks over to Robin and catches her when she passes out from exhaustion as a Mary is shown to have observed the fight. Back on the Wano mainland, Luffy eats the food provided by Caribou. As he eats, he reassures the Heart Pirates that their captain is alive, and Momonosuke tries to convince Shinobu to use her powers to turn him into an adult so he can transform into a full-grown dragon. Even though Shinobu warns him the process can't be undone, Momonosuke, is undeterred, saying if they don't, all of Wano will be destroyed.
