Rukia Kuchiki & Yasutora Sado vs. Shrieker

Rukia Kuchiki & Yasutora Sado vs. Shrieker is a battle involving Rukia Kuchiki and Yasutora Sado against the Hollow named Shrieker after Sado acquires a cursed cockatiel whose previous owners have all died horrible deaths (the bird actually being the container for the spirit of a dead child placed there by Shrieker as bait). It is Sado's first fight against a Hollow despite his inability to see it and Rukia's first fight with Sado.

Prologue
A few days after Ichigo Kurosaki becomes a Shinigami, Sado is talking with his friends Gitano Shigeo and Harutoki. Harutoki explains that he has come upon a cockatiel. He offers the bird to both of them as he is scared to have it. The bird is apparently cursed as all of its owners had died horrible deaths. As Shigeo tells Sado to not take the offer, a enormous steel beam suddenly falls on them. Sado, however protects his friends by catching the beam with his back. As both Shigeo and Harutoki express their concern, the bird thanks Sado for saving him and gives its name while asking for Sado's name. Sado responds back.ref>Bleach manga; Chapter 7, pages 1-4 The next day, Sado goes to school and brings the cockatiel with him. Ichigo, Rukia and their friends learn that Sado has apparently taken several injuries. Ichigo notices that the bird has a spirit inside of it. Rukia also notices but tells Ichigo to not worry, thinking it is probably a lonely spirit and nothing dangerous. She does tell Ichigo that it should be sent to the afterlife tonight as it could become a Hollow. Later that day, Ichigo encounters Sado again who has come into the Kurosaki Clinic because of serious injuries on his back. Upon seeing Sado's injuries, Ichigo immediately senses that the injuries come from that of a Hollow. Sado is laid down to rest but runs away from the Clinic with the cockatiel while Ichigo confirms with Rukia that Sado's wounds feel to be from a Hollow. . After learning that Sado is gone, Ichigo leaves with Rukia to try and track him down. As Ichigo expresses his frustration that they will only be able to find Sado after the Hollow has attacked, he comes up with the idea to track Sado down by sensing the spirit's reiryoku that dwells inside the bird. Although Rukia tries to tell Ichigo that it cannot be done, Ichigo quickly surprises her by using reiraku. Sado is then revealed to be hiding in a factory. As he converses with the spirit on whether they finally escaped from the Hollow, Sado senses that the Hollow found them. He tells the spirit that he will definitely save the spirit's mother. Sado then encounters Rukia and Ichigo but runs from them. While Sado runs, the two also come upon Karin Kurosaki. Rukia offers for Ichigo to take Karin home while she gives chase after Sado. . Rukia gives chase after Sado and as she does, she finds that she is unable to keep up because her Gigai's physical abilities are equivalent to a "normal" human. As she starts running out of breath, Shrieker suddenly appears behind her. He tells her that she smells nice. Turning her head back, Rukia notices Shrieker. Shrieker goes on, stating that she has a very tasty scent and so tells Rukia to let him eat her soul. As Shriekers moves to attack, Rukia curses the fact that she was so busy chasing Sado that she did not watch her back.

Battle
Although Shriekers manages to injure her, Rukia is able to rebound back from the strike. Shrieker is impressed at Rukia's resilience and wonders what is she, since she can see him. Ruki then suddenly surprises Shrieker by kneeing him and getting on top of the Hollow. Rukia proceeds to chanting the incantation for Hadō #33, Sōkatsui and blasts Shrieker from behind. Thinking that she had succeeded because her firing the spell means some of her powers were returning. However, she is surprised to see that her attack had no effect as Shrieker attacks her. Shriekers tells her that he recognizes her spell to be Kidō and taunts Rukia at her spell's ineffectiveness as he felt nothing. Shrieker goes on, deducting that Rukia is a Shinigami which explains her tasty scent. He then recalls that he had eaten the two Shinigami who had come to perform Konsō (Soul Burial) on the "Yūichi Shibata" and that they were the tastiest. Rukia asks if he means the spirit inside the cockatiel, to which Shrieker confirms Rukias then questions why Shrieker is chasing that spirit only for Shrieker to taunt Rukia again, saying that he might tell her if she quietly lets him eat her.

Far ahead, Sado notices a sound from behind. Yūichi Shibata informs him that it is Rukia being attacked by their pursuer. Sado then places the bird cage down and despite Yūichi's protests that he will get killed especially because he cannot see ghosts, runs back to go help. Meanwhile, Rukia is trapped against the wall by Shrieker's arm. He questions why Rukia is so weak and tells her to get out of her Gigai. As it looks that Shrieker will eat Rukia, Rukia notices a presence. Shrieker is then sent away by a punch to the face by Sado. As Shrieker yells in pain, Sado wonders if he hit him. Rukia is surprised that Sado hit Shrieker and questions if he can see Hollows. However, this is quickly disproved by Sado's attacks on empty space. Shrieker is relieved to find this out. He had been surprised for a moment but concludes that it is a mere fluke. Suddenly Sado's punch connects and hits Shrieker right in the face. Sado confirms to himself that he did hit him. Rukia is shocked at Sado's apparent lack of fear against an enemy that he cannot sense as while normal humans can touch Hollows and Shinigami because of their high density spirit bodies, they cannot see or hear them. Shrieker, slightly irritated by Sado's attacks, decides to take to the air. He then taunts them, laughing that they will not be able to attack him when he is in flight. Rukia then yells at Sado to not space out and run away because Shrieker is flying. Sado does not retreat, instead voicing his surprise that Rukia can see ghosts. He then interrupts Rukia's statement of their inability to attack from this distance and asks where. Rukia is slightly confused to which Sado asks which direction Shrieker is in since he is flying. Still confused, Rukia asks what can he do if he knows that. As Shrieker continues to taunt the two, wondering if he ought to attack like a falcon, he is suddenly surprised by Sado again. Sado answers Rukia's question by using his super-human strength to lift up a telephone pole. Again, Sado asks which direction and Rukia tells him to just swing down. Sado then swings the pole like a bat and knocks Shrieker down to the ground.

As Rukia and Sado stand before the fallen Hollow, Rukia tells him to give up and stay still as another Shinigami is coming to get rid of him soon.

Aftermath
Ichigo Kurosaki intervenes just as Shriekers moves to finish off both Rukia and Sado. Shrieker reveals a number of his abilities as well as how he has been able to slip away from the Shinigami for so long. Shrieker then proceeds to battling against Ichigo while Rukia and Sado watch on.
