In the manga, Toilet-Bound Hanko-kun, there is a story arc that is titled "Picture Perfect"(hence my digital archive's title and theme inspiration). In this section of the story, an interruption happens that shifts the way the characters interact and view one another afterward. 

This section of the story begins with the main character going to school like she usually does when suddenly she realizes something is wrong when she finds her ghost friend, Hanako, sitting behind her desk. She soon realizes that her classmates can see him as well when usually they are not able to, because he is a ghost, and goes by his human name, Yugi Amane. Confused and conflicted by what she is witnessing, Yashiro Nene decides to get to the bottom of the issue and find the reason why everyone believes that Yugi Amane is a student in their classroom and he has become a human.   

The focus and narrative then switch to one of the main three characters, Kou Minamoto. He is seen going to class like he usually does until he notices something unusual, he notices his old friend, Mitsuba Sousuke, in his classroom. The reason why he finds this unusual is because Mitsuba Sousuke, is in fact, a ghost who had recently died and is now interacting with Kou's classmates as if he has revived. Confused with this discovery and having conflicting thoughts, he continues to try to think about possible reasons why Mitsuba is there and tries to find an explanation as to why this is happening. 

 When the two friends, Yashiro Nene and Kou Minamoto, meet, they immediately realize that they're the only ones who notice the unusual situation they are in, where both of their supernatural friends are living beings interacting with their classmates. So when they reunite, they both decide to get to the bottom of the situation and find the answer to their question of how and why their dead friends are alive.

While they investigate and try to find an answer to the mystery, they finally find the answer when Mitsuba Sousuke breaks character and reveals that the world, in which they currently are in, is not real.

It is later revealed that the world in which they are in is a fake world that Mei Shijima has created, where both the characters Yugi Amane and Mitsuba Sousuke are alive even though they are dead supernaturals in the real world.  

The reason is then said that one of the other supernaturals, Tsukasa Yugi offered to grant a wish for Mitsuba Sousuke, his wish of becoming human. This is where Mei Shijima uses her supernatural powers as the school mystery no.4 to create this fake world within her drawings to create a world where all the main characters of the story are alive and attending the same classes/school together. Mitsuba, born a supernatural, wants to become human but that is something impossible for him to have, so he compromises to stay in this fake world. 

Although the leader of the school wonders, Hanako-kun, is supposed to stop this disruption, he decides to continue to pretend as well because he wants Nene to continue living. It is his wish for Yashiro Nene to continue living for many years after it is revealed that she will die within the next year. Still, he knows that changing the future is nearly impossible. He compromises to this fake world and traps Yashiro so that she can continue living since, in this perfect world, death does not exist. Both Mitsuba and Hanako wanted this fake world more than anyone else; a world where their wishes can come true, a perfect world where the whole group is alive and happy.

Connection

This section of AidaIro's Toilet-Bound Hanako-Kun connects back to Boccaccio's Decameron on the theme of worldbuilding. The characters build worlds that are different from reality as a way to escape their unhappy realities, where they can cope and forget about the chaos of their reality, and pursue a world that restores happiness and laughter(themes that are mentioned in the Decameron). It shows us that both of these stories include speculative narratives as pessimistic, fatalistic, and impossible since the characters are trying to avoid a harsh reality to pursue a utopian future, aiming for a state in which everything is perfect.

In this section of AidaIro's Toilet-Bound Hanako Kun, they introduce the story of the character Akane Sumire, her role as a god's bride, and the relationship between her and the school mystery no.6(whose supernatural power is life and death). This takes place in the past, recalling the school mystery number 6's backstory.

Sumire is first introduced as a girl who has been born for the sole purpose of fulfilling her role as a god's bride (in other words, a sacrifice/offering to the gods). This sacrificial routine has been done for many years in her hometown, which is followed by everyone because they believe it is essential to protect the land from monsters who attack citizens in return for providing the gods with girls as a sacrifice. Due to this role that she has been destined to follow, throughout her life, she has always been confined in her home and was not allowed to do many things, being limited in the things she was able to do and always had to be accompanied by someone. This is where the character no.6 is introduced.

No.6 is presented as a demon who has been given the job to be Sumire's caretaker and this is where the relationship/romance blossoms. Although they understood that their time was very limited due to Sumire's wedding day coming closer, they decided to create many beautiful and happy moments with one another until the day arrived. After her sacrifice was done, No.6 had this undescribable feeling left after she had been sacrificed and never understood the reasoning behind it. It is later revealed that he had been feeling guilty about her death all along, not being able to do anything about it or being able to protect and save her. So when they both reencounter each other after her death, they confess how they feel about one another and conclude that they both want to control the way they want to end their story, which results in both their tragic deaths, deaths that they both decided would be the best.

Connection:

In Boccaccio's Decameron, there is a theme that is a big part of the book, which is the theme of lovesickness that women experience. The topic of women experiencing love that is painful to them, and the sense in which women are not able to pursue their true loves freely due to the expectations others put on them. Sumire in this story, was always enclosed in her home, waiting for her wedding day, in other words, her "sacrification" and never had the opportunity to seek love elsewhere, which is something she had always desired to do. It connects to the theme of lovesickness in The Decameron since Sumire is a woman who was always enclosed in her home and was put limits on what she could do with her life. The topic of lovesickness also involves loves that ended tragically, which as explained above, their love ended in a tragic way in which they both die, but in a way in which they both desired to go.

This story of these characters also connects back to Butler's Parable of the Sower in the sense that they cannot avoid their tragic ending, so they use what they have to continue living a comfortable life with the limited time they have together.  Both stories decide to pursue a life where they decide to control the outcomes of their lives.
