Kensei Muguruma & Rōjūrō Ōtoribashi vs. Mask De Masculine

 is a fight which takes place during the Quincy Blood War. It focuses on the conflict between 9th Division Captain Kensei Muguruma and Sternritter "S" Mask De Masculine.

Prelude
After defeating 11th Division 3rd Seat Ikkaku Madarame, 11th Division 5th Seat Yumichika Ayasegawa, and 9th Division Lieutenant Shūhei Hisagi, Mask notices 6th Division Lieutenant Renji Abarai and 13th Division Lieutenant Rukia Kuchiki falling from the sky. When Mask asks him if they should confront the lieutenants, James points out how it will garner a great deal of attention for Mask, who proclaims they shall go. Wrapping Kazeshini around Mask's leg, Hisagi asks Mask if he believes he has won because he defeated them.

Grabbing Kazeshini by its chain, Mask pulls Hisagi toward him and clotheslines him while stating he believes this is the case. As Hisagi slams into the ground, Mask attempts to stomp on him, only for Kensei to catch Mask's foot with his own. As Kensei criticizes Hisagi for having been defeated without displaying the results of his Bankai training, Mask asks him if he is their friend, prompting Kensei to reveal his name and position as Hisagi's captain.

Proclaiming this is wonderful, Mask asks Kensei to not get in his way and says he does not wish to fight him because he is currently heading off to confront Rukia and Renji. Stepping forward, 3rd Division Captain Rōjūrō Ōtoribashi says there are two captains here before stating this is the perfect chance for Mask if he wishes to stand out. As Mask looks at Rose, Kensei states he will not waste his time and activates his Bankai, Tekken Tachikaze. Grinning, Mask says he has no choice and rips off his cape before proclaiming he will defeat Kensei in ten counts.

Battle
Leaping forward, Mask drop-kicks Kensei, sending him flying into a tower several meters away. As the dust clears, Kensei holds back a surprised Mask's feet with his hand and expresses disbelief at Hisagi having been beaten by such a small amount of power. Holding up his knuckle blades, which transform into brass knuckles, Kensei punches Mask in the stomach, cratering the area around them with the force of the attack. As Mask falls to his knees and gasps for air, Kensei lifts him into the air by the collar and asks Mask if he felt it before explaining the power of his Bankai.

Punching Mask in the stomach once more, Kensei proclaims he will blow him away before sending Mask crashing into a building. When James begins to beg Mask to not lose, Kensei notes he seems like the villain because the fight was so one-sided. As Hisagi wakes up and tells Kensei he get rid of James first, James begs Mask to get up. Appearing behind Kensei and Rose, a larger and stronger Mask casually throws Kensei into a building and punches Rose before revealing his epithet of "The Superstar" and explaining how the cheers of his audience become his power.
