Kisuke takes Hiyori to the Nest of Maggots.

Summary
Hiyori and Urahara head to the Nest of Maggots, and they arrive at the Second Division. Inside the barracks, one of the members of the Executive Militia tells Yoruichi that Urahara is waiting outside, claiming that he has already been given permission from Yoruichi. Yoruichi tries to remember what Urahara came for and casually says he can go do whatever he wants to. Suì-Fēng quickly objects, but Yoruichi tells her that she shouldn’t worry about him. The gate opens, and Urahara enters, dragging Hiyori along with him.

A while later, Hiyori asks her captain if they are even going to the Nest of Maggots, saying the they are on Second division grounds. Urahara explains that the Onmitsukidō was originally a separate organization from the Gotei 13, but due to Yoruichi, who is the Commander of the Onmitsukidō and the Captain of the Second Division, and the two organizations merged. In the Onmitsukidō, there are five separate divisions, and he was the chief of the Third Division, the detention unit. Hiyori teases Kisuke and call him jailer, but Urahara says it’s more like a babysitting job. Urahara say that his main job was to take people who committed crimes, put them into prison, and watch over them. Urahara stops walking, and explains the the detention unit watches over one special type of criminal; the ones who have joined the Gotei 13, but are put in jail if they could put others at risk because of their ideals or actions, or interfere with their division’s missions. Hiyori yells at Kisuke, telling him that she doesn’t understand, and demands a simplified explanation. After explaining again, he says that the facility, also known as the Nest of Maggots is located northwest the 2nd Division’s grounds beyond a thirty meter moat that surrounds the facility.

As the two Shinigami walk down the stairs to the facility. Hiyori looks around and comments that it looks like a cave, and questions why people would even lock criminals in a place like this. Urahara says it’s not much of a prison at all and opens the door, showing Hiyori the numerous prisoners. Urahara says that they may do whatever they please inside the facility, but are not allowed to leave. As they walk inside, the captain tells Hiyori to be careful, saying that they may attack at random. He says that the shinigami here never did anything wrong, but are deemed dangerous by the Seireitei. before the lieutenant can say another word, Kisuke explains that resigning is not permitted in the Gotei 13, unless the the person has severe personal issues. If that person takes too long to return, their name is removed from the register. However, people who decide to resign for no reason are forced into special detention. He continues, saying that the Central 46 has decided this rules, as they do not want a “misfit” that was once part of the Gotei 13 to go free. They lock them up in secret and say that they resigned. Urahara asks Hiyori if she thinks that these prisoners could do good if placed in the correct environment. The small girl says that she doesn’t and begins to yell at her captain.

From behind, a prisoner approaches, and addresses Hiyori and smiles. She instantly recognizes him and tells Urahara the he was one of her classmates she thought has resigned, and that other always called them ‘Big Mouth’. Big Mouth runs over to her and pleads her to help him. Before she can respond, one of the other members attempt to attack Hiyori. She reaches for her Zanpakutō, but realizes that she left it behind. Urahara effortlessly stops the attacker, saying that weapons are not allowed inside the penitentiary, and you have to control the prisoners with your bare hands. Urahara calmly looks at the prisoner, saying that he is quite rude to forget who he is in only two or three days, before proceeding to beat the prisoner to the ground. Seeing this, several other inmates attack the captain as well, but are all easily beaten. Big Mouth takes Hiyori hostage as a bargain for his release, only to be kicked by her, severely bruising her. Urahara chuckles and says his mouth has gotten even bigger, and tells Hiyori that they should get going.

They both walk down another staircase, as Urahara informs Hiyori that only one person in the Nest of Maggots is dangerous enough to be confined in a cell. the two walk over to the cell, and the prisoner speaks out, recognizing Urahara. Urahara claim that he has come to discuss something with him, addressing him as Mayuri Kurotsuchi. He asks him if he would want to leave the Nest of Maggots along with him and Hiyori. Mayuri is reluctant, saying that he is perfectly fine with the life he already has. Urahara admits to him that he think he is highly capable, and adds that he is thinking of creating an organization unlike anything in Soul Society, called the Shinigami Research and Development Institute, and he will only be one seat under him. Therefore, if he were the leave, the institute would be his. Mayuri smiles at his offer and accepts.

In the Kuchiki Family Manor, Byakuya is training his Zanjutsu skills. Ginrei appears behind him, praising the teenager's effort. Byakuya smiles and walks to his grandfather, saying that he's happy to see him. Ginrei tells Byakuya to finish up his training, stating that he has a guest. Before Byakuya can ask who, Yoruichi appears beside him. the agitated teenager immediately attacks the captain, calling her a "Were-cat". Yoruichi laughs and dodges, telling Byakuya he should be more respectful. Byakuya says that he is the next head of the Kuchiki Clan. Thus, he has no time for people like Yoruichi. in response, Yoruichi playfully steals his hair tie and appears on a roof. she taunts him, saying that he win against her, and uses Shunpo to escape. As displeased as ever, he claims that his Shunpo has surpassed hers a long time ago and uses Shunpo as well to go after her. After he leaves, Ginrei comments that Byakuya's skill would improve greatly if he learned to control his temper, and goes to drink some tea.

In the Thirteenth Division barracks, a frustrated Kaien Shiba once again declines Captain Ukitake’s offer for him to become lieutenant of the Thirteenth Division, saying that there are plenty more candidates he can choose from. Ukitake says that he favors him because he puts his duty before himself, and asks him if he’s heard that another prodigy joined the Gotei 13 this year, graduating from the Shinō Academy in only a year. Ukitake continues, saying that the prodigy is around the same age a Byakuya and is already a seated officer in his Division; the Fifth Division.

Elsewhere in Soul Society, Aizen praises the young boy who appears to have killed another Shinigami, and asks for the boy’s name. The boy introduces himself as Ichimaru Gin, and turns around to look at Aizen. Aizen asks Gin for his opinion on their Third Seat. Gin says that he wasn’t even worth the trouble. The lieutenant tells the boy that he is glad to hear that.

Nine years later, three mysterious figures watch as three souls suffocate and die.

Substitute Shinigami Work Diary
Rukia explains that working alongside the local representatives is also a task the Substitute Shinigami has to undergo. As Ichigo and Rukia finish off several Hollows, Zennosuke Kurumadani appears, telling them that they have stolen his job.
