Rena and Keiichi in 1988

As of 1988, Rena is attending college at Gogura University with Keiichi and Mion. Mion summons the club members to reunite in Hinamizawa like old times. After the festivities, the group plans to go to Angel Mort for dinner and to meet Shion, but Satoko asks to be by herself for a while.

Satoko meets Eua and becomes a looper. Rena is seen among other club members in various scenes during Satoko's revisits of 1983 and 1984. Satoko ultimately causes Rika to relive the June 1983 scenario.


Rena sees that her father Yasunori is seeing a woman named Rina Mamiya and hanging out with her seemingly every night. While cleaning Yasunori's room while he's out, Rena finds a business card listing Rina's workplace as Blue Mermaid.

Rena meets Keiichi at their usual spot and soon joins Mion as they head to school. Rena and the club have a picnic at the Furude Shrine. Later, Rena and Keiichi go to the junkyard for treasure hunting and find a Kenta-kun statue buried among the garbage. While walking home, Keiichi asks Rena about the dam project and if any incident occurred there, and Rena is quick to deny it. Keiichi is surprised and Rena says she doesn't know anything since she moved there a year prior.

The next day, the club plays a scavenger hunt game. After the game, Rena spaces out and tells the group she'll be resting in the infirmary before going home. As she rests, Satoko uses this opportunity to inject her with H173 and leaves. When Rena wakes up, she seems aware that Satoko was standing nearby but doesn't see her anywhere.

Sotsuep1 rena listens

Rena eavesdrops on Rina's conversation

Rena finds her dad's bankbook and sees that he's made many expensive purchases using the money he got from the divorce long ago. Rena's Hinamizawa Syndrome begins to develop as she scratches her neck in anger. Rena goes to Okinomiya and tries to enter Blue Mermaid, but a worker stops her. Rena then goes to a nearby coffee shop and sees Rina walk in, who still hasn't met Rena yet. Rina speaks with a friend about her new catch and shows interest in swindling him for his money, prompting Rena to leave and prepare a plan. Unbeknownst to Rena, Rina was feeling guilty about manipulating Yasunori like this and was going to break up with him, having sympathized with his daughter being raised by a single parent.

Rena goes to a hardware store and buys supplies like rope and tape. When her father asks about it the next day, Rena claims it's to bring something home from the junkyard. Rena moves her supplies to her base in the junkyard and buys more supplies the next day.

Rena goes home again and runs into Rina, who was hoping to meet her after dating her father for a while. Rina says she wants to become friends with her, and Rena uses this chance to convince Rina to come with her for treasure hunting. She takes along her cleaver wrapped in a cloth and brings Rina to her junkyard base. Inside, Rina explains she wants to break things off with Yasunori and asks Rena to convince him to stop seeing her. Rena prepares her materials and then starts choking her, thinking Rina is lying. Rina breaks free and runs away when she sees Rena drawing her cleaver. Rena manages to corner Rina after she falls down a junk mountain and kills her.

Sotsuep2 rena shadow

Rena's shadow falls over Keiichi as she prepares to kill him

Rena uses her tools to chop Rina's body into pieces and wraps them into bags, then hides them all in a container in the junkyard. The next day, Rena prepares to dispose of the pieces when Keiichi suddenly appears, wanting to help dig out Kenta-kun. Rena becomes afraid that he might've seen the pieces and prepares to kill Keiichi with her cleaver as he's reading some magazines, but he notices and freaks out. Rena claims she brought the cleaver to help with Kenta-kun. They successfully dig up the statue and wrap it up the next day.

Later, Rena runs into Keiichi's mother at the store, who offers Rena to make dinner for Keiichi the next time she has overtime work. As Rena is walking home, Ooishi stops by and interrogates her about Rina's whereabouts, as she's been missing for a day, and he knows Rina was visiting the daughter of one of her customers. Rena claims Rina came to her house and left after they talked a bit; Ooishi is convinced and drives off.

Rena spends the next few nights digging holes and burying Rina's pieces in them, her paranoia and Hinamizawa Syndrome worsening as she fears that Keiichi knows about all of it. During the Watanagashi Festival on June 19, Rena joins the club there, and after the cotton drifting, she watches Tomitake and Takano from behind a tree. She also spies on Keiichi a bit. The next day at school, Rena watches Keiichi going to speak with Ooishi in his car. Satoko goes to speak with her, seemingly to confirm if her symptoms are working as planned.

Keiichi begins to grow suspicious of Rena after learning of her background from Ooishi. On June 22, while walking home from school, Keiichi accuses Rena of hiding things from him. Rena says the same of him and starts rambling that she was working hard to be happy and doing her best for a long time. Rena accepts they both have something to hide and changes back to a neutral expression. That night, Rena goes to Keiichi's house and overhears him calling Ooishi and talking about her on the phone. Rena is fully convinced that Keiichi knows about Rina. Keiichi learns about Rena's eavesdropping when his dad tries to bring tea for two.

On June 23, Keiichi talks to Rika about his suspicions regarding Rena, and Rika encourages him to trust her, thinking this world is just like Onikakushi's; whatever weird things Rena did earlier were surely just a one-time-only thing. That night, Rena's house gets a call from Keiichi's mom asking her to make dinner for Keiichi. Excited at the opportunity, Rena accepts and fills her bento boxes with ropes and tools, heading to Keiichi's house and planning to dispose of him in a similar method to Rina. When Rena arrives at Keiichi's doorstep, he's afraid of letting her in and hesitates, recalling memories of beating Rena and Mion to death with a bat. He decides to believe Rika and lets Rena in. Rika watches this from behind a corner and is convinced she's succeeded.

She says that they will become the victims of Oyashiro-sama's curse this year, believing that her dad will live peacefully when she disappears after Keiichi's death.

She's forced to watch as Mion and Shion get shot and killed, and warns a newly-arrived Satoko to get away. However, she watches in horror as Satoko draws a gun and kills Ooishi, then shoots a dead Rika in the head and finally shoots herself.

Meanwhile, Keiichi gets sent to the hospital after an incident at Satoko's house and struggles to remember what actually happened. Rena visits him and explains what happened during the festival.

At the party, Rika exposes Satoko since she knew the trap box was a trap when she shouldn't. Satoko draws a gun and shoots Rika, then herself, much to the club members' horror.

After Rika and Satoko's final battle, they end up in a 1988 world similar to Matsuribayashi's. Rena and the adult club members retrieve Satoko and Rika from the river. While driving back, Rena and the club members give some insight into Rika and Satoko's friendship.

Satoko quickly comes up from behind and puts a bag over her head, ties up her hands, and injects her with an H173 syringe she obtained, then cuts the ties on Rena's hands and leaves her alone. Rena frees herself from the rest of the trap and goes home in a daze, slowly succumbing to Hinamizawa Syndrome.

While walking, Keiichi tells Rena about his concerns that she and Mion are hiding things from him, but Rena accuses him of doing the same and brings up his talk with Ooishi. Rena rambles about how she needs to try harder by herself otherwise she won't overcome things. During this, Rena starts to believe all of her happy memories with Keiichi were lies and that he knows about Rina, and decides she needs to kill him.
