Ichigo Kurosaki & Kūgo Ginjō vs. Shūkurō Tsukishima

Prologue
Jackie thinks to herself that Ichigo's mind has been trained from all the battles he has experienced, as Ichigo stares at her, Fullbring in hand. Suddenly, Ichigo is immersed in unusual reiatsu, as Jackie calls out to him, looking equally surprised. The black reiatsu flows forth from his Substitute Badge, enveloping Ichigo.

Yasutora Sado is still talking with Kūgo Ginjō, who comments upon Orihime Inoue's strange nature when confronted by Tsukishima, while Sado wonders whether his Fullbring has something to do with it. Sado asks him whether Tsukishima's abilities revolve around memory planting. Meanwhile, in Riruka's fish tank, Ichigo is seen struggling with the black reiatsu encapsulating his right arm, when Jackie tells him they are stopping the training.

However, Ichigo refuses, to which Jackie explains that his Fullbring is about to go out of control, and that she's never seen a Fullbring behave in that manner. She tries to explain to him, but he refuses to listen. She calls out to Ginjō and Giriko to get Riruka to negate the Doll House, but she is stopped mid-sentence. Ichigo's energy pins her to the ground, as he continues to convince her he is in control of his powers.

Ginjō levels with Sado, telling him that he is worried. He continues, explaining that if Tsukishima's abilities were as such, then he would have already told him. He explains that Tsukishima's Fullbring, "Book of the End" is called so because it can literally slice through any object, and that is the only thing it is capable of doing. Sado asks him whether his abilities have evolved during their time apart, to which he says that Fullbrings do not evolve.

Sado denies this, using his own Fullbring as an example, which prompts Ginjō to explain to him that his case was because he wasn't able to use his Fullbring's maximum power at that time, until he progressed to a level which such a thing was possible. He goes on to say that Tsukishima's ability is unrelated to Orihime's confusion, and asks him if Uryū experienced the same memory problems after being cut down by Tsukishima. Sado replies he isn't sure. Ginjō then says that if Uryū has the same symptoms as Orihime, then it is a cause for concern, but if not, then the person who attacked her was not Tsukishima.

However, Tsukishima interrupts them, slicing through the door of Xcution's base with his Fullbring, as the others look on in surprise. He goes on to greet Ginjō and the other Xcution members. Ginjō asks Tsukishima just what he is doing at their base, but Tsukishima ignores his question, wondering where Jackie and Riruka are. He turns his attention to the fish tank, stating that that is where they are hiding. He brings his sword down upon it, and Ginjō yells for him to stop.

From the opened fish tank, black reiatsu emerges pours out, surprising Ginjō and Sado, whereas Tsukishima comments that it is interesting. Ichigo then emerges from it, black reiatsu forming around his body in the shape of a Shinigami's Shihakusho.

Battle
An exhausted Jackie lies on the ground of Xcution's headquarters, murmuring Ichigo's name as he stands before her, enveloped in a cloak of black reiatsu. Ginjō and Sado look on in shock, with the latter silently identifying the true form of Ichigo's Fullbring as a "clad-type". He compares the reiatsu shroud to Ichigo's Bankai, recalling that his overcoat was a part of it. He comes to the conclusion that Ichigo's true self is to be cloaked in his own power. Tsukishima explains to Ichigo that Riruka's Dollhouse forcibly ejects its contents if the container is destroyed. He expresses his surprise that Ichigo has mastered Fullbring to such a degree, telling Ginjō that he should have told him sooner.

Ichigo swings the blade of black reiatsu, enveloping his right arm, at Tsukishima, who he deflects with his Book of the End. Ichigo asks who Tsukishima is, to which Tsukishima expresses his disappointment over not already being mentioned to Ichigo. Sado suddenly recalls that Ichigo does not know about Tsukishima. Tsukishima introduces himself, but before he can continue speaking, Sado activates his Brazo Derecha de Gigante and leaps towards him. Ginjō shouts at him to wait, but Sado blasts a hole through the wall. Yukio remarks that Sado is an idiot for doing so, while Riruka runs into the room, asking about what is going on. Giriko informs them that he will take care of the neighbors, police, and fire department. Yukio wonders about who is going to pay for the damage, ignoring Riruka as she shouts at them to explain once again.

As Sado and Ginjō land on a rooftop, the latter calls the former an idiot, saying that now that Ichigo's Fullbring has activated, they can afford to tell him about Tsukishima. Sado says they cannot, expressing his concerns that they have no idea how powerful Ichigo's Fullbring is, or if he can even handle using it. He remarks that telling him that Tsukishima attacked Orihime would only detriment his performance in battle. However, Ichigo overhears them, walking up behind Sado, realizing that his friends were only looking out for him, and that he did not even realize it. Tsukishima lands a few feet behind Ichigo, who asks if he attacked Uryū as well. Tsukishima simply asks what he thinks, prompting Ichigo to charge at him with his blade of reiatsu in hand. Tsukishima blocks his blow, leaping away from him off the building while remarking that Ichigo is good.

Ichigo proceeds to propel himself off the roof, leaping towards Tsukishima. Sado contemplates on what Ichigo just did, realizing that he used Fullbring on the concrete to increase his jumping height, as well as on the air to propel himself forward. He silently questions the extent to which Ichigo has mastered Fullbring. Landing on a railing, Tsukishima remarks that Ichigo has already gotten the grasp of his Fullbring powers. However, he then launches himself towards Ichigo and swings at his sword, stating that his Fullbring is still incomplete. His Book of the End breaks right through Ichigo's sword and dissipates the reiatsu shroud on his left arm. He then kicks Ichigo's exposed shoulder, knocking him towards the ground. Tsukishima explains that by concentrating his attacks on Ichigo's right arm, he can make it lose its Fullbring shroud, and comments that Ichigo couldn't even break his fall. As Ichigo recovers from the fall, Tsukishima charges toward him with his sword raised over his head. However, Ginjō appears before him with his Fullbring active and apologizes to Tsukishima, saying that he cannot let Ichigo fight him yet.

Tsukishima asks Ginjō if he is going to interfere, but Ginjō says that it is Tsukishima who is interfering. Ichigo tells Ginjō to step aside, but Ginjō elbows him in the back and refuses, saying he cannot have Ichigo dying on him. As Ginjō and Tsukishima clash, Sado attempts to stop Ichigo from interfering. However, Ichigo refuses to just watch the person who attacked Orihime and Uryū and goes after them.

Ginjō destroys a building by charging his Cross of Scaffold with reiatsu and then firing it, prompting Tsukishima to criticize him for endangering other people. Ginjō claims that he has only been targeting empty buildings. Ichigo then appears above Tsukishima and attacks him, but is unable to hurt him. Tsukishima states that Ichigo does not get it and that his Fullbring is incomplete, but he is cut off as Ichigo becomes further engulfed in black reiatsu form his Fullbring and Tsukishima comments that his Fullbring changes quickly and his power is much closer to his previous peak as a Shinigami.

Yukio then uses his Fullbring, Invaders Must Die, to remove Ichigo from the battle. Tsukishima comments that Yukio would not want him to have any contact with Ichigo as he nears maturity.

Aftermath
Ichigo appears in the middle of Yukio's Fullbring, demanding that he be released. The "Save" bar reaches finishes filling up, as it states that the process is now complete. Tsukishima interjects, stating that Yukio made it so that he could not interfere with Ichigo's training, but asks whether it would have been smarter to instead lock him away, to which Yukio explains that his battery power is insufficient to save the former Xcution leader.

He explains that someone has called the police and fire department, stating that it would be inconvenient for him to be caught at this stage. Riruka appears behind Tsukishima, pointing her Love Gun at him and tells him to leave immediately. Yukio explains that they will be taking Ichigo with them, and that it would be better for him to stay, in order for him to be exposed.

At Karakura General Hospital, Uryū Ishida is approached by Orihime Inoue. Uryū apologizes for calling upon such short notice, to which Orihime asks whether he is well enough to stand. She tells him that she could heal him now, in order for him to leave, to which he agrees, stating that he had to seclude himself from the others if he was the true target. He tells her to heal his injuries, stating that Ichigo has come into contact with his attacker, due to his fluctuating reiatsu.

He asks Orihime whether she sensed it too, to which she states that they had the same attacker, much to his surprise. Ichigo is released from Yukio's Fullbring, emerging onto the floor. Ginjō explains that this area is their backup headquarters, but that it is less comfortable than the other location. Yukio butts in, saying that he won't make it comfortable if he talks like that. Ichigo inquires about Tsukishima, to which Ginjō states that he has temporarily retreated.

He continues, stating that he could've killed Yukio and the others if he desired, but this fact proves that he is especially interested in Ichigo. However, Yukio tells him that he is overthinking things, and that Tsukishima would never dare to attack him whilst holding his console. He attempts to leave and help Giriko at the other base, but Ginjō stops him, telling him to help with Ichigo' training. Yukio protests at this, claiming that his batteries are low, to which Ginjō tells him to plug it into the wall.

Yukio refuses outright, as Ginjō states that he isn't sure of how Tsukishima found them out, stating that it is a possibility that he traced their reiatsu. He states that Yukio's Fullbring is most suited to this, considering that it emits zero reiatsu. Yukio agrees, and Ginjō explains that a live battle seems to work best for him. Ichigo asks who he is going to fight next, to which Ginjō states that he will be his opponent.

As Orihime walks at night, she recalls back to her meeting with Uryū. She remembers how Uryū explains that, since their injuries were completely different, it is unlikely that they were the same person. She informs Uryū that the attacker's ability was known as Fullbring, to which she asks him whether his attacker revealed such a thing. He explains that he thought it was a Zanpakutō's ability until she informed him otherwise.

As she walks along, she is approached by Yasutora Sado, who explains that she was just at the hospital healing Uryū. She states that he will recover fine, so long as he rests, to which Sado states that he is glad to hear he is alright. He tells her to fill him in on the details as they walk, to which Orihime asks where are they going. Sado explains that they will be going to Ichigo's side, in which her powers will play a crucial role in the next stage of Ichigo's Fullbring training.
