After Gerard Valkyrie grows to gigantic proportions with The Miracle and begins smashing through the city, Askin notes that he probably has not noticed Lille Barro's defeat before explaining the positions of and rumors surrounding the other Schutzstaffel members to Ichigo Kurosaki, who is lying incapacitated on the ground before him.
Upon seeing Yasutora Sado and Orihime Inoue approaching them, Askin steps back to avoid Sado's attack before catching both of them in Gift Bad.
As Sado and Orihime wonder why they cannot move, Askin explains that he can lower any resistance of those who step within Gift Bad and that he has currently chosen Spiritual Energy before revealing that this is causing them to be 'poisoned' by the dense Spiritual Energy in Wahrwelt.
When Sado questions his usage of the word 'poisoned', Askin explains that The Deathdealing allows him to determine the lethal dosage of a substance by taking a large amount of that substance into his own body.
Askin proceeds to reveal that he has not killed them yet simply because he has had too many cafe au laits, but is interrupted when Yoruichi appears behind him and questions why he does not simply strangle them
Noting that Bambietta Basterbine said something similar to him before and that it still irritates him, Askin kicks at Yoruichi while demanding to know if she finds it so hard to be delicate, prompting Yoruichi to casually dodge and flip away before wondering if Askin believes his opponents are beneath him.
When Askin denies this and states that he simply prefers killing his opponents elegantly with The Deathdealing instead of strangling them, which he believes is more suited for women like Yoruichi and Bambietta, Yoruichi activates her Shunko and notes that Askin is trying to describe how the beautiful do things.
Askin brings out his Heilig Bogen and proclaims that a woman's value lies in her style and presentation instead of her superficial qualities before firing two Heilig Pfeil at Yoruichi, who merely dodges one of them while grabbing the other before throwing it back at Askin, who is hit in his left shoulder.
As a shocked Askin is sent flying back, Yoruichi admits that he is an interesting man and tells him that he will be letting them through now before activating Shunko: Raijin Senkei and engulfing Askin in a massive blast of energy.
The energy from the attack levels the surrounding buildings as Yoruichi pulls Orihime out of Gift Bad with a cable.
Telling Orihime to heal herself, Ichigo, and Sado before going on ahead with them, Yoruichi promises to join them once she confirms that Askin is dead.
However, Yoruichi is interrupted when her brother Yushiro appears and attempts to hug her.
When Yoruichi dodges him, Yushiro rebounds from the rubble and evades her attempt to block him before trying to grab her from behind, only for Yoruichi to perform a reverse headbutt on him before pointing out that he is supposed to be with Kisuke Urahara and the other Shinigami.
Confirming this, Yushiro explains that he came here because he thought Yoruichi would need his help more than the multiple captain-class Shinigami in his group would, prompting an angered Yoruichi to sarcastically state that Yushiro must have become much stronger since they last met.
As an oblivious Yushiro tearfully proclaims that he has indeed become stronger, Askin, having survived Yoruichi's attack with only light injuries, interrupts by informing Yoruichi and Yushiro that he has heard enough of their touching reunion.
Ichigo, Sado, and Orihime leave at Yoruichi's behest, prompting Askin to express exasperation at having let them get away before noting that he does not want to get hit by Yoruichi's 'Rising' attack again.
Hearing this, Yushiro angrily corrects Askin and lunges toward him when Askin unknowingly confuses his gender.
Askin prepares to take him on, but is shocked when Yushiro punches him in the face before unleashing a barrage of blows on him.
When Askin notes that he is much stronger than he looks, Yushiro proclaims that a mere Quincy could not hope to beat him before using Shunko: Bakuen Muso, which creates an enormous explosion.
Though criticizing Yushiro for being reckless and pointing out that they do not know what could have happened had she not already weakened Askin, Yoruichi admits that he deserves some praise for mastering the Shunko which she taught him to such an extent in a short period of time, which makes Yushiro blush.
However, they are interrupted by Askin, who has survived Yushiro's attack with considerable burns and expresses disbelief at him being so proficient with a technique that he only just learned before informing Yoruichi and Yushiro that they will no longer be able to kill him with their Spiritual Pressure after infusing his body with such large quantities of it.
When Yoruichi notices that his wounds are healing, Askin explains that he has gained immunity by increasing the lethal dose of her and Yushiro's Spiritual Pressure before noting that she will not be able to wound him at all if she keeps staring in shock.
Yushiro activates his Shunko once more and attacks despite Yoruichi warning him to wait, but his attack dissipates as Askin reminds him that he has already experienced and become immune to this attack before shooting Yushiro through the chest with three Heilig Pfeil.
As a shocked and concerned Yoruichi rushes to Yushiro's side, Askin walks away while noting that Yoruichi's slow comprehension of his power was a fatal error.
Soon afterward, Askin lies on the ground while noting that he did not retreat and yet survived, which he finds hard to believe.
Pondering whether or not this is a result of his immunity, Askin asks Yoruichi, who is struggling to stand up, what she thinks of this, prompting Yoruichi to claim she did not listen because she thought Askin was talking to himself.
Getting to his feet, Askin points out that Yoruichi should not have the composure to listen to him or even be alive after being hit with a Hybrid Gift Ball of Spiritual Pressure, oxygen, and nitrogen, but Yoruichi claims Askin has a strange sense of humor to be intentionally leaving her on the verge of death.
However, Askin states that he has been trying his hardest to kill her and that anyone else would be dead by now before asking Yoruichi to stop downplaying how strong she is.
Looking at the wounded Yushiro, Yoruichi mentally notes that she needs to heal him, but is surprised when Askin appears in front of her and points out how she did not react to his presence until now, which means she is close to death.
As Askin claims that he will be able to attack first no matter what Yoruichi tries at this point and that this is a fatal situation for Yoruichi, Kisuke Urahara appears behind Yoruichi while agreeing that the wedgie which Yoruichi gave herself is a lethal sight to behold, prompting Yoruichi to angrily kick him in the chin.
When Urahara demands to know how Yoruichi could kick him after he came all this way to help her, Yoruichi tells him to stop looking at her rear end and start analyzing the situation, causing Urahara to note that 'wedgie' may have been a crude thing to say.
Yoruichi continues to berate Urahara as Askin notes he is a troublesome interloper.
When Urahara says he is flattered that Askin has heard of him, Askin reveals that Urahara is one of the Special War Powers whom Yhwach warned the Sternritter about.
Claiming that he is being overestimated despite how honored he feels, Urahara asks Yoruichi for confirmation as she suddenly leaps into the air, to Askin's surprise.
As he wonders what Urahara did to make Yoruichi able to move once more, Askin realizes that this is what he had heard about, as Urahara was designated as one of the Special War Powers due to his ability to perpetually adapt to any strategies that his opponents use against him.
Meanwhile, Urahara follows Yoruichi through the air and confirms her guess that he injected her with an immunity booster of some kind, though he admits that it will only last for five minutes due to being a prototype. As Yoruichi activates Shunko: Raijin Senkei, but Urahara interrupts her by stating that they should do a certain thing.
When Yoruichi adamantly refuses to take on such a form again, Urahara notes that he will have to force her to, only to be interrupted by a Heilig Pfeil from Askin flying past them.
Yoruichi begins attacking Askin, who incapacitates her with a punch to the stomach while noting that she is still not able to defeat him, but suddenly transforms into her Shunko: Raiju Senkei: Shunryu Kokubyo Senkei form after Urahara triggers it from afar.
Urahara explains the specifics of Yoruichi's new form and how it is overriding Askin's immunity to Askin as Yoruichi attacks him.
As Askin wonders what this new form is, Urahara provides the name for him, prompting Askin to realize that Yoruichi cannot understand human speech right now.
Yoruichi leaps forward and slashes Askin's shoulder with her claws before sending him flying through several buildings with another attack.
Leaping out of the rubble, a panicked Askin notes that her Spiritual Pressure cannot have changed from what he became immune to so suddenly, only for Urahara to reveal that her Spiritual Energy is changing based on her mood, which is changing so unpredictably in her new form that it is almost like she is another person.
As Yoruichi attacks Askin again, Urahara compares the changes in Yoruichi's Spiritual Energy to those of the flu, which is why Askin is no longer immune, and reveals that her Spiritual Energy changes 48 times per second as Yoruichi blasts Askin with an enormous amount of energy.
Engulfed by electricity, Askin is sent crashing into the city below as Yoruichi lands on a nearby roof, only to be alerted by Urahara waving a cat toy at her.
Leaping toward Urahara, Yoruichi happily tackles him and begins licking his face before nuzzling on his lap, prompting Urahara to note that the drawbacks of this form lie in how only he can control it and how Yoruichi can only revert to her usual self when her moods dictate it before admitting that he does not mind because of how cute she is.
When Yoruichi begins shuddering and moaning, Urahara realizes that the immunity booster is wearing off and promises to remove the poison from her system after confirming that Askin has been finished off.
However, Urahara is shocked when a Gift Ball Deluxe engulfs the surrounding area, which prompts Askin to explain how this is the largest Gift Ball that he is capable of creating before emerging in his Quincy: Vollstandig, Hasshein, which he claims is an uninspiring name.
Askin reveals will adapt to mutations in any 'poison' he is resisting. Asking notes that he only needs one second to experience all 48 variations of Yoruichi's Spiritual Energy before declaring that no amount of Spiritual Energy changes will allow her or Urahara to harm him from now on.
Askin sets up a Gift Bereich around his Gift Ball Deluxe to prevent Urahara from escaping.
Asking Urahara what his next move is and wondering if he is already out of tricks, Askin erects a Gift Bereich around his Gift Ball Deluxe and admits that he does not like talking tough because he prefers to appear confident before telling Urahara that there is no way to escape from the Gift Bereich.
Urahara notes that Askin must really not want them to escape and states that he does not seem to be the kind of man who acts out of loyalty, prompting Askin to admit that he has a personal interest in Yhwach due to the latter trying to destroy all three realms and create something new to replace them before asking Urahara if he is not curious about what Yhwach will create after destroying the realms.
Hearing this, Urahara moves forward and slashes at Askin, who quickly leans back to avoid the strike before leaping back to a safe distance while praising Urahara's ability to move with such speed while inside the Gift Ball Deluxe.
When Urahara says that he is not interested, Askin realizes that this is Urahara's answer to his question and admits that he thought they were alike until now as Urahara notes that Mayuri Kurotsuchi may have shared Askin's desire to witness a new world if Askin had asked him.
Urahara claims that Mayuri would not be interested in something created by Yhwach because scientists like them will simply create something no one has ever seen before themselves if they want to witness it, eliciting a wide grin from Askin, who admits that this is not a bad answer before proclaiming that he would prefer to see what Yhwach creates while creating and throwing a Gift Ring at Urahara, who is surprised when it disappears from his vision before suddenly losing an eye as the shrunken Gift Ring makes contact with it, causing it to burst.
Explaining how the Gift Ring concentrates all the power of The Deathdealing into a single point to inflict instant death on whatever part of the body it pierces and is reserved for opponents who are too strong to kill with lethal doses, Askin notes that lowering Urahara's lethal dose and removing all his options were not enough before claiming that his only option is to kill off each of Urahara's organs until none of him is left alive.
However, Urahara merely notes that there is nothing else for it since Askin is earnestly trying to kill him before activating his Bankai, Kannonbiraki Benihime Aratame.
Surprised by this, Askin reveals that Yhwach had not provided the Sternritter with any Daten on Urahara's Bankai, prompting Urahara to admit that this is the first time he has used his Bankai in front of anyone in the Wahrwelt.
When Askin asks him what the ability of his Bankai is, Urahara wonders what the point in doing so is since he will not simply tell Askin, who claims that would be scary to attack without even trying such a thing.
Conceding that this is a fair point, Urahara tells Askin that he will see what his Bankai does soon enough regardless of whether or not he is told.
Upon seeing his left arm being split open, a shocked Askin dashes back several meters, causing his arm to sew itself up as Urahara praises his cool-headedness for not simply cutting off his arm and instead ascertaining that his Bankai's power is limited by its range.
Claiming that he simply does not have the courage to cut off his own arm, Askin wonders what Urahara is doing before looking on in surprise as Urahara reveals that his Bankai can restructure anything it touches as the arms of the woman behind him repair his eyes.
Urahara leaps into the air and attacks Askin, managing to wound him, before turning around and clashing with him as Askin expresses his disbelief at Urahara being able to see him after having his eyes killed, prompting Urahara to explain that he can see due to his eyes being restructured.
Urahara restructures his left hand to increase its physical power before blasting Askin back and through multiple buildings with a single swing of his sword.
However, as Urahara moves toward him, Askin recovers while complaining about how this is turning into a battle of brute force after he had seemingly dragged Urahara into his pace before reminding Urahara that they are still within his Gift Ball Deluxe, which begins growing in power, and that he has simply been restraining its power the whole time.
When Urahara claims that he can barely crawl around inside of the Gift Ball Deluxe at its current power, Askin points out that his Bankai is still dangerous, only for Urahara to note that he is acting too late as a hand bursts through Askin's chest while clutching his heart.
Explaining how Askin never said his Gift Bereich was impossible to enter, Urahara reveals that he created a route for someone to get inside from the outside before thanking Starrk as Starrk shot a Cero from blank-point range, completely destroying Askin's heart in the process as well as missing Urahara by a little bit.
Askin who is still alive even though his heart was destroyed, reveals the power of his Gift Ball Deluxe magnifies upon his death.
Starrk clicks his tongue while Urahara collapse on the ground due to fatigue and soon the Gift Ball Deluxe explodes.
