Renji Abarai vs. Mask De Masculine

 is a fight which takes place during the Quincy Blood War. It focuses on the conflict between 6th Division Lieutenant Renji Abarai and Sternritter "S" Mask De Masculine.

Prelude
After blowing a hole through 3rd Division Captain Rōjūrō Ōtoribashi's torso with his Star Flash, a laughing Mask sees Rose's hand twitch and notes he is very resilient before firing another Star Flash at Rose, only for Renji to appear in front of Rose and block the blast with Zabimaru, saving him. Noting Renji deflected his Star Flash, Mask demands to know who he is, prompting Renji to state he is a villain.

When 13th Division Lieutenant Rukia Kuchiki lands behind him, Renji tells her to tend to the wounded Rose and 9th Division Captain Kensei Muguruma before stating she does not need to interfere because he can handle Mask on his own. As Mask expresses confusion, Rukia begins to bandage Rose and notes Mask will not present much of a challenge to Renji before leaving with Rose and Kensei.

Admitting he was expecting Rukia and Renji to team up on him, Mask notes this is what Kensei and Rose did before saying the underhanded tricks which villains use do not matter against him. Saying he will take this as a compliment, Renji asks Mask to not take it personally when he beats him, prompting Mask to note Renji appears to have said something awe-inspiring before revealing he has completely lost the ability to hear. Remembering how he crushed his own eardrums, Mask calls out to James, who drags himself over and asks Mask what he can help him with. As Renji expresses surprise at James still being alive, Mask asks James to cheer for him so his eardrums can heal, prompting James to cheer him on. When his eardrums heal, Mask proclaims they have returned to their former glory before asking Renji to talk more, prompting Renji to state this sickens him. Noting Renji has insulted him, Mask proclaims this cannot go unpunished before leaping toward Renji.

Battle
Using his Star Rocket Headbutt, Mask crashes into Renji, creating an enormous explosion upon impact. Proclaiming getting crushed to death by his headbutt of justice is a good way for a villain like Renji to die, Mask expresses surprise upon seeing seeing Renji standing to the side. Lifting up his arm, Renji elbows Mask in the back, sending him crashing into the ground and cratering the area around them. Pulling his head out of the ground, Mask notes Renji evaded his blow and managed to counterattack with an elbow and says this is obviously pure luck before stating Renji has made a fatal mistake by making him angry. Holding up his fist, which has a star on it, Mask tells Renji to look at it.

Explaining how the star becomes larger as he becomes angrier, Mask proclaims the star signifies his duty as a superstar to crush all evil, Mask hits Renji with his Star Killer Punch and reveals his blows are ten times more powerful when the star appears on his fists. As Mask proclaims he will cover the surrounding area with Renji's brains because this is the price he must pay for defying the righteous, Renji catches his fist with his hand before noting Mask's Star Killer Punch may not be able to kill a Shinigami. Expressing anger, Mask proclaims a villain cannot mock the righteous blows of a hero before rapidly punching at Renji while expressing his intent to kill him. As Mask hears his voice, James asks Mask to forgive him before being sliced apart. When Mask wonders how James received these wounds, Renji reveals he attacked James while Mask was busy punching at him. When Mask proclaims he is a coward, Renji points out how all villains are coward before slashing Mask across the abdomen.
