Ichigo best challenge by By:Jean Bio (best way to read e books TXT) 📕

how it is possible, but he then realizes that something is wrong and asks who this is. Ichigo looks up with his face half covered by a mask as he screams that he is nobody.[11]

Byakuya is surprised by Ichigo's inner Hollow.
Ichigo goes into an insane rage as his inner Hollow takes over and he slashes Byakuya across his chest wounding him. He then shatters Byakuya's blade with his bare hand. Byakuya regains his composure and calls forth another sword just as the crazed Ichigo charges at him. Ichigo then fires a spiritual blast, which Byakuya notices, with surprise, is black. Before he realizes it, Ichigo attacks him from behind, but Byakuya survives and asks if he is a Hollow. However, before Hollow Ichigo can finish Byakuya off, Ichigo rips off the mask, apologizes for the Hollow’s interference and tells him they should start from the beginning. Byakuya agrees to forget what just transpired, but points out that neither of them have the strength to continue this for much longer and decides that they must end it with the next blow. Ichigo agrees but asks again why Byakuya won’t save Rukia, to which he answers back that he will tell him if he defeats him. Byakuya then uses the technique "Shūkei, Hakuteiken", which amazes Ichigo, who states the he has no technique like that, since all Zangetsu taught him was Getsuga Tenshō. Thus, he states that he will just place all of his strength into one attack. The two charge at each other, releasing a torrent of powerful spiritual pressure.[12]

The final fight of Byakuya and Ichigo.
In the end, Ichigo is wounded but so is Byakuya, who tells Ichigo that the reason why he supports Rukia's death sentence is because he believes in following the rules, even if the rules mean the death of a family member. The concept of personal feelings is overridden by the rules and he states that emotions are useless and he never had them to begin with. Ichigo tells him he doesn't understand, and if he was in his position, he would fight the rules. Byakuya finally understands that Ichigo never was fighting him, but Soul Society's rules and he thinks that Ichigo has the same personality as Kaien Shiba, who he remembers as having a distasteful ferocity. Byakuya then tells Ichigo that his ferocity has shattered his blade, and therefore, he can no longer pursue Rukia and he leaves the area.[13]
Ichigo Vs Rukia

Rukia, slowly recovering from having her memory erased by the siblings, remembers that Ichigo Kurosaki and Renji Abarai are her past friends. Homura is greatly upset by this and declares that she would never forgive Ichigo for trying to steal Rukia from them. She uses her unique power to wish that she, her brother, and Rukia will become one so that the three will never be separated again. Her wish is granted, resulting in a twisted form of Rukia, referred to as "Dark Rukia." Dark Rukia proceeds to activate Mayuri Kurotsuchi's invention, which begins to destroy Soul Society and flood the area with snake-like monsters. Renji deals with the other enemies, leaving Ichigo to do whatever is necessary to stop Dark Rukia.
Ichigo is forced to fight Rukia, but never attempts to actually attack her, instead only evading her attacks. He desperately asks her to remember, earning a reply that Dark Rukia will use her power to erase Ichigo's memories of Rukia so that only the siblings will remember her. Ichigo states that the bond between him and Rukia transcends memory. Renji's soul was able to remember Ichigo, meaning the bonds between friends can never be broken, even if they are forgotten. Dark Rukia's attacks become more vicious and she nearly decapitates Ichigo, but she is halted by Byakuya Kuchiki's Rikujōkōrō. Byakuya sees the resemblance between Dark Rukia and Hisana Kuchiki and decides that he must be the one to exterminate Dark Rukia.


Dark Rukia is purified
Ichigo protests that Rukia is still in there and that the bond between him and her will never break. As Rukia begins to Hollowfy, the binding spell begins to break and Renji notes that she is going beyond help. However, Ichigo is reminded of his first encounter with her, upon seeing Kon begging Ichigo to save Rukia, where she had asked Ichigo if he wanted to save his family, and tells Byakuya that he wont give up. Byakuya tells him to do as he wishes and Dark Rukia breaks free from Byakuya's Kidō, enraged and declares her intention to kill Ichigo. Ichigo focuses his power and tells Rukia that it's his turn to give her his power. She and Ichigo clash for the last time and Ichigo impales Rukia with Tensa Zangetsu. Rukia is separated from the siblings and the Hollow that had been inside them is killed and purified.
Powers & AbilitiesEdit
Enhanced Strength: Dark Rukia has incredible strength as she was able to completely break out of a level 61 binding spell cast by a Captain-class Shinigami, Byakuya Kuchiki.
Hollowfication: Upon increased arousal out of anger, Dark Rukia undergoes a unique form of Hollowfication. Her teeth become jagged and her eyes turn completely black. This is seen during her fight with Ichigo where she becomes visibly more powerful and vicious, nearly decapitating him.

Teleportation: Like Homura and Shizuku, Dark Rukia has the ability to teleport a short distance. She uses this to attack and surprise her opponents. It is unknown if she can teleport over longer distances.

Hollow ScytheEdit
Dark Rukia wields a large and exquisitely designed dark red, double-edged scythe in combat. The scythe itself originally manifested in the form of a small, weak Hollow that had a scythe-like tail used to erase an enemy's memories. Some time after the Hollow merged with the siblings and they were transported to Hueco Mundo the scythe was created and used by Shizuku. Upon the creation of Dark Rukia the scythe (and the knowledge of its use) was transferred to her. Despite its size, she uses it with great proficiency and speed, able to contend with Tensa Zangetsu's agility and power (although Ichigo was holding back), throwing the weapon at him on occasion.

Rift Attack
Rift Attack: Dark Rukia swings her scythe in front of her enemy which opens a purple rift that unleashes a powerful blast of dark energy. This attack was strong enough to send Ichigo flying back while in his Bankai state.
Memory Erasure: Dark Rukia's scythe is capable of phasing through solid objects. Should the scythe phase through a living being, they are physically unharmed yet their memories are erased. This power has the ability to target only certain memories (rather than all memories) and has the capacity to affect other beings linked to that particular memory. For example, by erasing Rukia's memory that she ever became a Shinigami, everyone who knew her forgot she ever existed. Oddly enough, Modified Souls such as Kon seem to be immune to the effects of this type of memory erasure.

Ichigo vs Ichigo

During Ichigo's more difficult battles, the mask he thought he discarded kept reappearing on his body in places where there would normally have been fatal wounds.

As Ichigo fought Renji Abarai, Renji used Zabimaru to hit Ichigo near his heart, but the sword was stopped for some reason. After the fight, as Hanatarō Yamada healed Ichigo, he found that the same Hollow mask Ichigo thought he threw away was what blocked Zabimaru. Ichigo, thinking the mask as a good luck charm, wanted to keep the mask; but Hanatarō took it, and fearing it, threw it into the sewer water. The mask was gone again for a time.[17]
Later when Ichigo runs into captain of 11th Division, Kenpachi Zaraki, he is stabbed in his chest by the far superior combatant. Seemingly dying Ichigo is pulled into his inner world by Zangetsu, while there he meets Hollow Ichigo for the first time. Zangetsu explains that now is the time for the test to see if Ichigo is worthy of using him. He then tells Ichigo if he wants to wield him again then he must take him back with his hands, as his opponent will be himself.[18] Ichigo is forced into a fight with Hollow Ichigo with a nameless katana while his other being has Zangetsu. Hollow Ichigo gains an advantage as he releases his spiritual power and begins to spin Zangetsu by its cloth, similar to a flail. As the two fight, Hollow Ichigo asks Ichigo whether he thought it would be so simple to fully control his Zanpakutō. He then makes note that Ichigo only thinks about himself and never considered drawing out Zangetsu's power. Hollow Ichigo further explains that there's more to Zangetsu's power and if he can open up and lend it his power, it will become even stronger. He laments that Ichigo will not do this or rely on his Zanpakutō and only worries about making himself stronger. Tired of playing around, Hollow Ichigo decides to show Ichigo the right way to use Zangetsu and moves to attack. As they cross swords Hollow Ichigo is surprised to find the nameless katana in his hands and Ichigo holding Zangetsu. Seeing Zangetsu has decided Ichigo is worthy of using Ichigo then awakens back in the real world.[19]

As Hollow Ichigo stands there with a broken katana still somewhat confused he asks Zangetsu if Ichigo is gone before asking him if that was all. Zangetsu tells him that it is and that he is sorry to have bothered him. Hollow Ichigo tells him it was no problem as Ichigo is the owner of the inner world and it would be problematic if he didn't win. Even though he was unwilling he had to help, he then asks for Zangetsu to send him back. As Hollow Ichigo begins to fade away he then tells Zangetsu to train Ichigo well as one day that power will be his.[20]

In the real world as Kenpachi and Ichigo prepare for their last strike, Kenpachi's Reiatsu took the form of a skull, while Ichigo's takes the form of his Hollow mask, showing how Hollow Ichigo is supporting him.[21]

After the battle, Yoruichi Shihōin took Ichigo to heal him; as he awoke, she commented on how a Hollow mask saved Ichigo's life. Ichigo was surprised, mentioning how Hanatarō threw it away, giving
