Prelude As Lieutenants Rangiku Matsumoto and Momo Hinamori look on in shock, a monster forms from Emilou Apacci, Franceska Mila Rose, and Cyan Sung-Sun's left arms. Apacci states the technique they just used is called Quimera Parca, and their "pet" is called Ayon. Rangiku, looking at Ayon, and notes it feels as if she is staring into a bottomless hole

As Ayon immediately charges at Rangiku, she instinctively releases her Zanpakutō Haineko, but the monster, too quick for her, tears through the right side of her abdomen. As Apacci states she forgot to warn them about Ayon's immense strength, Momo yells out to Rangiku.[3] As Rangiku drops to the ground, Momo, grabbing her, uses Bakudō #37. Tsuriboshi, creating a star-shaped cushion of spiritual energy which, connecting to the buildings around them, stops their fall. As Momo tells her she is going to heal her, she realizes Rangiku cannot breathe because the area from her ribs to her intestines has been gouged away. Ayon goes up to Momo, and as Momo unsheathes her Zanpakutō, Ayon punches her in the stomach. As she flies off in the distance, Momo thinks to herself it is insane for both her and Rangiku to be defeated in a single blow. Lieutenant Izuru Kira uses Bakudō #37. Tsuriboshi to save Momo while Lieutenant Shūhei Hisagi wraps Kazeshini around Ayon's neck. As Hisagi and Kira tell Momo they are going to take care of things now, Ayon examines Hisagi's Zanpakutō

Hisagi, cautious, uses Hadō #11: Tsuzuri Raiden, sending an electric current through his Zanpakutō to shock Ayon, causing it to fall. He deduces Kidō might be its weakness and attacks, but Ayon recovers, breaking Hisagi’s chains easily. Realizing Ayon’s strength, Hisagi attempts to dodge but is grabbed. As Ayon prepares to devour him, Lieutenant Iba intervenes, but Ayon’s hidden eye shoots a Cero at him. Hisagi is slammed into a building and tossed aside, while Ayon turns its attention to a worried Kira.
