Story

Day 1

Rin Yamazaki is sound asleep having a strange dream which seems to take place underwater, a mysterious figure shows up and Rin questions if they were there. She then gets woken up in a car by Seitaro and starts a small argument. Yuka Kikuchi asks Rin if she slept well, which Rin replies that she was until Seitaro rudely woke her up which she calls him 'baldy' for having gray hair. Seitaro asks Yuuta Takahashi, who was driving the car, if they were in the mountains yet but Yuuta tells them that he has no idea where they are, which made Rin kick Yuuta's seat in anger, and comments that she didn't want to go on a trip in his 'lousy ol' GPS-less car'. After Yuuta feeling hurt from the kick and telling Rin to not kick his seat, suddenly the car stops. Rin angrily says that she'll check on the car and gets out. Seeing nothing wrong with it, she questions on why it stopped. After walking forward, an old man is seen asking Rin why she's in the mountains. After being startled, the old man offers Rin and her friends to stay at his mansion until their car was fixed, which all of them agreed to and followed the old man back to his home. The old man shows everyone into their rooms. After showing Rin her room and telling her that he'll be preparing dinner for them, assuming that they were hungry. Rin will go outside and comment on the huge swamp and tries to read the stone monument near it, the old man will ask her if she was curious and tells her the legend of the mermaid swamp. After telling Rin the legend, the old man tells her that dinner was ready, to Rin's relief. Rin finishes her dinner first and tells them to clean up after her, which Seitaro tells her to do it herself, and Rin replying to him to 'work on his names while he's at it'. After taking a bath, Rin will go to sleep and dream about being underwater again and sees the figure again and tries to tell it to stop staring or else she'll kill it.   

Day 2

Rin wakes up after having the dream. After talking to Seitaro and Yuuta in the living room about the car still not looking any better, the old man will tell them that he had to go to a memorial service for a few days and leaves the mansion to them, and tells them not to go walking in the mountains as well. After the old man leaves, Rin will get into the bath and starts worrying about Yuka because she started to feel cold. Rin starts to become drowsy and falls asleep in the bath. She wakes up to find the bath water all filthy and disgusting. She freaks out and Seitaro comes in and asks what's wrong and sees her naked, which she furiously hits him for barging in unexpectedly. After talking about the bath water which appeared to be swamp water according to Seitaro, Rin checks up on Yuka, she then goes back into her room and charges her cellphone and goes to bed.  After falling asleep, Rin dreams about the mansion filled with water. After walking out of her room, she sees a dark figure going towards Yuka's room. Rin follows it and sees it near Yuka. After waking up, she goes check on Yuka and finds her body all swollen and screams. Seitaro hears her and sees Yuka. He tells Rin to call an ambulance using the phone in the living room. After using the living room phone which wasn't working because the power is out, Rin went to get her cellphone only to find it that it was out of battery. After talking to Yuuta about Yuka's unexplainable swelling, Seitaro, who went out on the mountains, tells them to help search for a map to get out and get Yuka help. Looking around, Rin questions about whether to light the fire in Yuka's room after hearing her mumble that she was cold and Yuuta acting weird. After searching, Seitaro will give her a lighter and a lantern to give to Yuuta, which Rin heard him jerking in his room and leaves the stuff near his door. Worrying too much about Yuka to sleep, Rin searches again and was able to find some firewood in the storeroom. If she lights the fire in Yuka's room, Rin will comfort her and tells her she'll be OK and they'll get her to a hospital soon.If she doesn't light the fire, Rin can still continue her search for the map. Rin then goes to the old mansion and sees somebody in the swamp but soon find that there was nobody there. Yuuta comes up from behind, startling Rin. He asks her why she was up and tells her to go back to her room and rest which she refused at first until he stomps forward and tells her to go back again, which this time she agrees and goes back. Rin falls asleep and sees two little kids talking about going to their grandma to talk about the 'fishy fish'. Afterwards, they are seen talking to their grandmother about the mermaid legend. The grandma tells them that the mermaids are angry at them when asked if the 'fishy fish' are mad. She then says that "But outsiders... Outsiders will be cursed by her.", which is why "No outsiders may come to this house."  

Day 3

Rin will wake up and go check on Yuka and sees Yuuta coming out of her room. After checking on Yuka, Rin will wake Seitaro up calling him "Early-baldy" and tells him to make breakfast for her. After waking him up, they'll be sitting at the dining room table eating snacks and talk about getting Yuka to a hospital. After having finished eating, Rin will go to the old mansion again. After standing on a table to get a spring from the top of a high bookshelf, Rin falls off and becomes unconsious. She then hears someone telling her to get up and finds Yuka back to normal, and Rin yells at her for making her worried then saying that they should forget about the map because Yuka might be hungry. Yuka stops Rin and tells her a secret, saying "I'm a hostage here.". Rin will see Yuka shaking and Yuka telling Rin to help her, she backs up to see Yuka leaking swamp water and coming towards her, yelling that she's cold and to take her back. Rin then finds Seitaro waking her up and telling her she can't be relied on for anything. Rin searches the old mansion more and finds a golf club in one of the room. Rin was about to leave the room when an old phone rings and Rin answers it. The phonecall will be from Yuka and she'll either say "I'm sorry" if Rin lit the fire or "Help me" if she didn't. After Rin goes back to the main mansion, if she lit the fire she'll find Yuka dead and screams, which Seitaro will come in and tells Rin to get out of the room. Rin will being sitting outside her room with her knees up to her face, asking Seitaro what happened to Yuka to which he replies that it was no good and that lighting the fire sped up the process of her dying because "even her organs couldn't take it". Blaming herself for lighting the fire and Seitaro saying that it wasn't her fault, Yuuta will come out of his room and ask what happened which Rin and Seitaro didn't reply. Yuuta will check on Yuka and run to the kitchen and stab himself. Seitaro will lay clothes over his body and tells Rin not to go in there. If Rin goes back and didn't light the fire, she'll find Yuuta next to Yuka's bedside and yells at him to get away from her. After Yuuta compliments on Yuka and why Rin can't be like her, he brings out a knife and Rin realizes that the Ophelia paintings in the mansion caused Yuuta's insanity. Rin will go around the mansion with the golf club and smash all of the Ophelia paintings. Once she smashed the last painting in the old mansion, she finds Yuuta collapsed on the ground and Seitaro coming in and finds Yuuta on the ground as well. Rin will explain what happen to Yuuta which Seitaro disagreed, Yuuta will wake up and Rin will kick him yelling at him for chasing her around with a knife. Rin will talk to Seitaro about her going to get help which led Seitaro to argue with her stating that she'll get lost in the heavy fog and that he'll have to go after her. Not listening to Seitaro, Rin will go up into the mountains and collapse from exhaustion and sees Yuka again. Rin will either say that she's dead or she's at the mansion. After hearing Yuka wanting Rin to take her back, Rin states that she's the one who wants to be taken back.  Seitaro will go find her and sees her crying. After asking if she was OK, she faints and she's carried back to the mansion. Rin will be in bed while Seitaro comments on her reckless decision. She'll talk about the mermaid's curse and that it was the cause of Yuka's illness and Yuuta's insanity, but Seitaro tells her that she's thinking differently from fatigue and there was no such thing. He'll state he's at their ropes end and he will suddenly have a headache which worries Rin. Still thinking it's the curse, Rin remembers the name "mermaid swamp" and decides to jump in the swamp into find any clues. After swimming towards the bottom, Rin finds a hairpin at the bottom. A black shadow then starts swallowing her and she couldn't breathe. Seitaro jumps in the swamp and argues with Rin, telling her to do something productive like finding a map. Seitaro will have another headache and Rin apologizes saying that it was her fault that he's not feeling well. After getting dark again, Rin will go back to her room but states that she's too afraid to sleep and goes back to the old mansion. She finds a hidden room in the fireplace and finds a somewhere map, but she senses someone in the room and tries to escape. But she accidentally drops the lantern, suddenly sees the mermaid and then promptly faints at the sight.   

Day 4

She wakes up and goes back to the upper room to find out she slept until morning. Rin will see Seitaro waiting for her and he asks where she went and explained she found a secret room with the map and asks if he could look at it. But instead Seitaro goes up to her and hugs her, which makes Rin blush and telling him to let go. Asking him what's wrong, Seitaro says that he's scared and about what happened to Yuka and Yuuta and wanting Rin to stay by his side.  Rin can accept and hug Seitaro back, apologizing for making him worried. She'll say that they should go back to the main building to which he agreed, but when Rin started walking back, Seitaro knocked her out cold. Rin will see she's underwater again, thinking that it was only a dream, but finds out that it wasn't a dream and that she couldn't breathe. Crying out for help and for Seitaro, he is drowning her in the bathtub at the main mansion. This will result in a game over.  

Rin can refuse and she'll push Seitaro away and yell at him that he's gone crazy too. Seitaro will bring out an axe and tries to get Rin to come with him but Rin shoves him away again and runs. Rin will keep running until she in the first west side door on the second floor and Seitaro will corner her and tells her that she can run, but she can't hide. Rin could choose to dodge Seitaro's attack and he misses and fall through the floor. She'll go back downstairs to the room beneath to find Seitaro with an axe in his stomach, all bloody. She'll panic and try to think of a way to stop the blood but Seitaro will tell her to take the axe out. After doing so, Seitaro will get up and tells Rin to stay away from him and walks out. Rin will follow him in front of the swamp seeing him about to fall into the swamp. She'll cry out that she didn't want to be alone and she needed him but he told her to escape, either on her own or with Yuka and Yuuta if the fire wasn't lit. He tells her that he wanted her to live and finally falls into the swamp. Rin will go after him and try to reach for him but fails and goes back up to the surface and cries. Yuuta will come out and ask Rin why there was blood on the ground which she answers that Seitaro took an axe to the stomach and fell into the swamp. Yuuta will panic and tell Rin that he'll fix the car and they'll get out soon. She'll stop crying and finds Seitaro's wristwatch at the shore and looks at the map. She'll go to the study and read a book about telling direction and finds out that there was something across the swamp. She uses a motor boat and gets her way across and finds a grate which led to a underground cave, after walking in she'll state that she's freezing cold and keeps walking until she finds a door. Rin can also not dodge Seitaro's attack and kicks him in the stomach instead, making him drop the axe and fall onto the floor. She'll kick him a couple of times out of anger yelling at him to never chase her with an axe again and calling him a creep, but then she'll realize that he was unconscious and waits for him to wake up. After he groaned about his stomach hurting, she'll kick him again and they start arguing about what happened. Still believing in the curse, Seitaro still disagrees and Rin almost yelled out that he likes her until he yells at her to stop. He admitted that it's the curse and said he'll help her. Rin will ask Seitaro in the study a few things and borrow his wristwatch and he'll tell her how to check direction. She'll find out that there was something across the swamp and use the motor boat, Seitaro will come along as well. They'll find a grate covered with grass and walk in which leads to an underground tunnel. On the way to the room, Rin will stop and Seitaro will ask Rin what was wrong and she'll reply that she's cold, which led to Seitaro giving her his jacket for warmth. They'll keep walking until Seitaro finds a door and tells Rin that they should go in.  

Endings

Yaobikuni

If Yuka, Yuuta, and Seitaro died, Rin will enter the room and finds a few mermaids in fish tanks. Wanting to get out, Rin hears someone lock the door and she tries to open it. She hears footsteps and cries out to unlock the door to let her out, but the person didn't listen to her and left. Rin backs away and screams, after being locked in for a few days, she collapes and states that she's hungry for meat. She gets up and walks towards a mermaid tank and screams out for meat. Afterwards the old man comes back and questions Rin still being alive and finds out that she ate the mermaid's flesh, Rin had blood all over her mouth and hands mumbling that she ate the mermaid's meat. The old man tells her to come with him seeing how insane as she is and that no one would believe her. He tells her a legend about a nun eating mermaid flesh and became immortal, he asked Rin what she'll do. Rin was left standing in the middle of the mountain forest and screams out that she ate the mermaid's meat and she won't die, then runs off laughing.

Forever Deep

If Yuka and Yuuta died, Seitaro and Rin will enter the room and find the mermaids in the fish tanks. Rin will ask Seitaro if they're really mermaids but Seitaro couldn't decide if they were. After Rin yelled at him if they were once more, Seitaro finally agreed that they were and Rin decides to pick up a pickaxe and try to smash them. Seitaro tries to stop her but Rin says that they were the ones who killed Yuka and Yuuta and she wanted them back. Dropping the pickaxe and banging on the tanks yelling at the mermaids to give Yuka and Yuuta back, Rin falls to her knees and crying. Rin is seen sitting in front of the swamp while Seitaro tries to walk through the mountains to find a way out, but fails and ended up back at the mansion. Rin stops him and reminds him that they couldn't make any progress and that they were "locked in." Seitaro would sit down next to Rin and they start talking about Ophelia drowning in the water, looking beautiful while dying. Rin states that if she wanted to die, she'd drown in the water without suffering beautifully, which led Seitaro agreeing that he'd go the same way. They'll be seen gone, drowning themselves. 

Secrets

If Seitaro died, Rin would try to open the door, only to find it locked. After laughing about it she tries again and starts blaming herself for Seitaro's death, she then yells out to open the door but does not succeed. She falls to her knees crying. She'll go back to the mansion and Yuuta will see her and tell her to come back inside before it rains, she agrees. She turns around thinking she sees and hears Seitaro on the other side of the swamp. She says that she sees but Yuuta tells her that he doesn't see him and reminds her that Seitaro fell into the swamp. Rin shots back saying "What are you talking about?" and walks up saying that Seitaro's alone in the swamp, lonely, and that she'll go meet him. Yuuta calls out to Rin but she tells him to go home with Yuka and that there's no more hope for her. Afterwards, she apologizes and jumps into the swamp. 

Underwater Dream

If everyone is alive, Seitaro and Rin will enter the room and find the mermaids in the fish tanks but Seitaro exclaims that they're not mermaids but a woman's corpse. Seitaro starts explaining what the mermaid legend really is but questioned why the legend was created until Rin added that it was created so no outsider would fall victim. Seitaro agrees but states that finding out about the legend didn't help and leaves the room, when Rin was about to leave she told the mermaids to leave them alone until they told her to take them back to the earth. Rin agrees seeing that they're not really mermaids and helped them by blowing up the cavern with Seitaro's help. After the ground caved in, Seitaro asks if Rin was hurt, seeing her crying but Rin says that the tears are warm and that they're the girls' tears. After going back the old man comes back revealing his name to be Yukio Tsuchida telling them the truth about everything. Rin was about to call the police but Seitaro stopped her and the old man told them that the fog was starting to clear and he gave Yuuta a map so they can leave. After walking back, Yuuta said that his car was fixed and that they can go down the mountains. Carrying Yuka into the car, as they drove down the mountains Rin looked out the window until Yuka woke up to be back to normal which made Rin scream out her name. Rin says that when they went to the hospital, the doctors didn't find anything wrong with Yuka, Yuka told them that she couldn't remember anything other than her being cold, Yuuta is working hard to buy a new car with a GPS although Rin is doubtful about travelling with him again, Seitaro started calling her Apewoman, and Rin no longer has dreams about being cold in the water.

Relationships

Seitaro Wakasugi

From the beginning, Seitaro teases Rin. Rin calls him names, and Seitaro name-calls as well. Though she gets annoyed by it, it is implied that she doesn't take it seriously. Fan speculation has believed that this constant bickering may be a sign of romance. Seitaro is very helpful to Rin throughout the game, reading texts and explaining things such as Ophelia's story to her. Although she doesn't seem to listen or fully understand sometimes, he doesn't seem angry about it. Near the end of the game, Seitaro admits that he doesn't want to be alone or Rin to be sad, though it is unclear if this is true or part of his deception while being controlled.

Yuuta Takahashi

Yuuta also enjoys teasing Rin like Seitaro. However likewise, he is shown to care for her when he rescues her from the swamp (if Seitaro died). Their interactions with each other are few otherwise in the game as Yuuta is not quite himself for most of them.

Yuka Kikuchi

Rin and Yuka are both very close friends and Rin was the first to check on her before she became sick. This became Rin's driving motivation throughout the game and her desire to help Yuka became so strong that it manifested itself as a dream after she fell off a stool and was knocked out. Notably in the endings where Yuka dies, Rin is absolutely devastated and blames herself for her death. In contrast, Rin is very happy and relieved that Yuka is back to normal in the Underwater Dream ending.
