During 1978, a dam project that would've flooded the village was made and led by Mr. Hojo. Everyone, except for the Hojo family and some other people, were completely against the Dam Project, because flooding the village would anger their god, Oyashiro-sama. In 1979, the Dam Project was stopped. During the Watanagashi Festival that year the dam construction manager was killed by the other construction workers. Also, that night, the leader of the construction workers went missing. Later, the Yamainu, which is a force that works for TOKYO, an organization that researches a syndrome called the "Hinamizawa Syndrome", discovered the leader's corpse before the police did, and then used it as a live specimen for their organization.

During 1980, on the day of the Watanagashi Festival, Mr. Hojo and his wife fell off of a high-cliff viewing platform. The police investigators later found Mr. Hojo's body, but weren't able to find his wife's body. During the day of the 1981's Watanagashi Festival, Rika's father died of a mysterious disease. Apparently, his wife, Rika's mother, drowned herself in a nearby swamp to make Oyashiro-sama happy. The police investigators weren't able to find her body, but they did find her shoes near the river, along with a suicide note next to them.

Also, during 1982, on the night of the Watanagashi Festival, Tamae Hojo, the aunt of Satoko and her older brother, Satoshi, was murdered. Police had suspected Satoshi at first, since he and Satoko were known to have been abused by their aunt and uncle, until another police station caught the real killer, who was a drug addict that wanted to repeat the curse. A couple days later, Satoshi disappeared, leaving his sister and uncle, who, later, left Hinamizawa, because he was scared that he'd be killed, too.

Last, during 1983, which was last year, Miyo Takano, who was a nurse at the Irie Clinic, was revealed to have been behind the curse of Oyashiro. She had been working for TOKYO to learn more about the Hinamizawa Syndrome. To prove the Hinamizawa's existence, she was going to kill Oyashiro's reincarnation, Rika, to cause the whole village to go insane, and then let out a poisonous gas into the village that'd kill everyone. Fortunately, she had been stopped by Rika and the others before she was able to do so, and was then taken away to be treated for the Hinamizawa Sydrome, which she had somehow gotten infected by.

I can't believe no one ever told me about any of this. Was it just that they wanted to forget about all of it? I'd understand if they had wanted to put the past behind them. I just can't help but feel left out. It really would've been nice to know that they had fought in a very intense battle against a very strong organization. I would've been so happy and proud of them. Fighting against people who are older, stronger, and more skilled than me is something I'd never be able to do.

After Oishi drops me off at school, I barge into the building and storm down the halls. I slam the door open, causing it to hit the wall very hard. The loud thud causes a lot of the students to jump and/or look up at me. My face heats up as I walk over to my desk. I slide into my chair, ignoring the stares of the other students.

"Catina-chan, where have you been?" Ms. Chie asks, getting up out of her chair. She narrows her eyes at me and crosses her arms over her chest.

I might as well not lie to her. Almost everyone was here when I had run out of the classroom, meaning that if I lie, someone could easily tell her the truth. "I needed to blow off some steam," I said nonchalantly.

Ms. Chie sighs and lets her hands fall down to her sides. "We'll talk about this later. Right now, I'd like you to start on the math worksheet I had passed out earlier." She points to a stack of papers that are sitting on an empty desk. I nod and get up. I grab a sheet and then walk back to my desk. I sit down and immediately begin working on the first problem. I'm happy that no one's looking at my anymore. I hate it when a lot of people stare at me.

During lunchtime, instead of pushing our desks together so we can talk to each other, we stay where we are. Lunchtime was very boring and quiet. There were a few people who were talking to each other, such as Satoko, Rika, and some others, but that's about it. Everyone else was quietly eating. Out of the corner of my eye, I see that Keiichi hasn't even touched his lunch. He's just moving the meat and rice around with his chopsticks.

After lunchtime, Ms. Chie announces that we're going to have to have recess inside, because it's raining outside. There were a bunch of groans coming from the younger kids. Ms. Chie says she needs to go ask the principal something and then leaves the room. I pull a book out of my over-the-shoulder bag. I was about to start reading when I hear a smacking sound. I look up from my book and my eyes widen in shock.

Rika, whose left cheek was red, was lying on the ground in front of Mion, who was standing over her menacingly. Mion grabbed Rika by the collar and pulled her up off the ground.

"Don't you dare say I'm being unfair!" Mion snaps. She throws Rika into the wall, causing Rika to shriek a little. Mion grabbed a chair and dragged it behind her as she walks towards the younger girl.

"I'm being completely fair!" Mion yells before hitting Rika with the chair. She raises the chair up and brings it down again. Rika covers her head in fear and curls up into a ball. Mion repeatedly hits her with a chair until Satoko jumps in the way, her arms spread out.

"Stop it, Mi-chan!" she exclaims, glaring at the older girl.

Mion returns the glare and sneers. "The brat deserves it for saying I'm being unfair towards that red-headed freak!" She tightens her grip on the chair. "Now move out of the way or else I'll punish you, too!"

Satoko, instead of moving away, just stands there. She straightens her posture, making her a little taller. A fire of confidence burns in her eyes as she glowers at Mion. "No," she says in a monotone voice.

Mion growls in anger. She raises the chair above her head, ready to bring it down on Satoko's head. But, before she can, someone grabs her wrist and pulls her away from Satoko. It was Shion.

"Don't you even think about hurting Satoko-chan or I swear I'll—"

"Shion-san, stop!" someone yells. I turn my head towards the voice and see Keiichi, who's now standing up. Mion and Shion both look at him with emotionless eyes. Satoko turns around and starts helping Rika stand up. I get out of my chair and run over to where they are. I drape one of Rika's arms around my shoulder, while Satoko gets the other, and then we help her out of the room.

We walk down the hallway and into the principal's office, where Ms. Chie and the principal are quietly talking to each other. When they see us, they're eyes widen, sort of like how mine had when I saw that Mion had slapped Rika. Ms. Chie helps Satoko and I set Rika down on the bench that's outside, while the principal calls Dr. Irie, who, since Takano's gone, now fully owns the Irie Clinic. Detective Oishi had told me that Takano had used the Irie Clinic as another place to study the Hinamizawa Syndrome.

Dr. Irie arrives and takes Rika away. After they're gone, Ms. Chie asks me and Satoko what had happened. When we're done explaining, she marches out the principal's office. We silently follow her down the hallway and, while she stands at the doorway with her arms crossed over her chest, slip into the classroom.

"Sonozaki-san, come with me right now!" she yells before storming off down the hall. Mion reluctantly leaves the classroom and follows her.
