Ichigo Kurosaki vs. Jin Kariya: Rematch

Ichigo Kurosaki vs. Jin Kariya is a battle that takes place in the Bount Cave. It involves Ichigo finally being able to use his Bankai again.

Prologue
Ichigo Kurosaki arrives at the location of the Bount in the Bount Cave. Jin Kariya walks up to Ichigo and remarks that he's going to need more time to achieve the Bount objective. Ichigo suddenly realizes that Kariya killed his fellow Bount, Ugaki, on purpose and calls him out on killing his friend just to slow him and the others down a bit. Kariya informs Ichigo that what he did wasn't his intention, but that his plans have simply changed. Kariya then states that he's going to leave the Human World now and Ichigo concludes that Kariya must be planning the same thing as Sōsuke Aizen. Kariya tells the other Bount to begin with the preparations and Gō Koga suddenly chants a spell that opens up a world-connecting gate. Kariya explains to Ichigo that the Bount are able to manipulate dimensions by absorbing Human souls and storing their power. As he says this, Maki Ichinose tells Kariya that he'll perform the ceremony.

Battle
Kariya decides that he'll test his power against Ichigo and the two of them begin battling. Ichigo runs towards Kariya and he swings his Zanpakutō at the Bount but his blow is blocked by Kariya's arm. Kariya then takes his finger and pushes it towards Ichigo, causing the Shinigami to be sent crashing towards a wall. Ichigo gets back up to battle and he wonders how Kariya easily stopped Zangetsu unarmed. As this happens, Koga tells Mabashi to watch this battle closely as this is the true power of a Bount. Kariya then runs towards Ichigo and Ichigo thrusts his Zanpakutō towards Kariya, but the Bount easily catches it with his hand. Kariya then runs his arm through Ichigo's stomach, causing Ichigo to cough up a large amount of blood. Kariya kicks Ichigo up into the air; when Ichigo drops down Kariya kicks him across the room, causing the Shinigami to drop his Zanpakutō.

Kariya picks up Ichigo by his hair and he asks him if he's already finished. Kariya then throws Ichigo onto the ground. He remarks that this was no test of power. He then asks Ichigo why he doesn't use his Bankai so he tells Ichigo to pick up his Zanpakutō. However, seeing Ichigo's lack of strength causes Kariya to kick the Zanpakutō away from Ichigo and decides to finish off the Shinigami. He decides that it would be a shame if Ichigo died ignorant though, thus, he states that he's going to explain what the Bount true goal is. Koga begins to get worried because of this but Kariya tells him not to worry since he doesn't remember trying to hide his goals. Kariya informs Ichigo that his plans aren't like Aizen's plans and that he and the other Bount are going to head to the Soul Society to take revenge against them for creating the Bount.

Kariya explains to Ichigo that long ago Soul Society conducted experiments for unknown reasons. He states that the only thing that is known about these experiments is that Soul Society saw Humans only as research subjects. Kariya remarks that after looking through the records he found who was responsible for this, but he doesn't reveal who it was. He then explains that an accident from one of these experiments caused a huge explosion and that explosion created a new type of Human that was scattered throughout the world. He reveals that they were the Bount and that at first the Bount were worried about how they would live in the Human World. He explains that they tried to hide their ability from the other Humans, but it was impossible and they were shunned by society. However, Soul Society soon offered the Bount a chance to live with them; on the other hand, Kariya reveals that it was really all a part of the Soul Society's plot.

Kariya tells Ichigo that the cave they are currently in is where many of the Bount tried to hide to escape persecution. He states that there are only a few of them left now. He then asks Ichigo if he understands that the Soul Society tried to erase the Bount from history. Kariya then states that he and the other Bount won't let the Soul Society have an eternal future; they will annihilate it. Ichigo responds to Kariya that he won't be able to understand what the Soul Society did to them, but even with that excuse it doesn't give them a reason to take the lives of other Humans. Ichigo then picks up his Zanpakutō, tells Kariya that he won't forgive him and fires off a Getsuga Tenshō at the Bount. However, Kariya easily deflects the attack with his arm and charges towards Ichigo, allowing him to stab his hand across Ichigo's chest.

Kariya tells Ichigo that he doesn't have enough power to stop him; still, Ichigo still tries to fight him. Ichigo charges towards Kariya and swings his Zanpakutō at him. The Bount easily dodges the attack. Kariya then reappears behind Ichigo and kicks the Shinigami in the stomach. Kariya kicks Ichigo again, causing him to fly up into the air. Ichigo crashes onto the ground; as soon as he does so Kariya kicks the Shinigami near a wall. Kariya steps on Ichigo's back, states that the souls of Humans have increased his power and that Soul Society will soon kneel before the Bount. Ichigo thinks to himself that he was able to get this far because of everyone else; he can't give up now. Ichigo struggles to get back up and he tries to get his Zanpakutō. He calls out to Zangetsu. However, Kariya picks up the Zangetsu before Ichigo can reach it. Kariya asks the latter how it would be like to be killed by his own Zanpakutō; but, to Kariya's surprise, Ichigo grabs his Zanpakutō and runs it through his own stomach.

Ichigo appears in his inner world and, is immediately confronted by Zangetsu. After they talk about Bankai, Zangetsu tells Ichigo not to be afraid. He asks why Ichigo fights and desires power. Ichigo states that he became a Shinigami to protect those close to him and that by making a promise to his soul he was able to achieve Bankai. Ichigo then asks Zangetsu to lend him his power. Zangetsu tells him to believe in his own power. Back in the cave, Ichigo is shown to be wielding Zangetsu instead of Kariya. He immediately activates his Bankai, Tensa Zangetsu.

Ichigo immediately disappears from Kariya's sight. He then reappears right next to Kariya and thrusts his Zanpakutō towards him but Kariya dodges the attack. Ichinose calls out to Kariya but Koga tells Ichinose to be quiet and to control the Senkai gate as "he'll" be coming soon. Kariya charges towards Ichigo and attacks him but his blows are blocked by Ichigo's blade. Kariya then tries to outmaneuver Ichigo but Ichigo sees through his moves and easily dodges his attacks. The two then continue clashing with each other while destroying much of the area around them. After commending each other on their skills, the two decide to finish up their battle. As they charge towards each other, they're suddenly interrupted when a Quincy arrow is shot in between the two of them.

Aftermath
Uryū Ishida appears and uses his Quincy powers on the world-connecting gate so that the Bount can enter into Soul Society. After Kariya and the other Bount leave for their destination, Uryū explains that the Bount needed the Quincy so that they could head into Soul Society. Uryū then states that he did this because Shinigami and Quincy become much stronger in Soul Society and that if they fought them here they would have lost. Yoruichi Shihōin and the rest of the Shinigami in the cave then appear and everyone decides to head into Soul Society to stop the Bount.
