## Plot

Mahiro comes back to her room, having just bathed with Mihari and tells the girls that the bath is free for whoever's next. Asahi sniffs Mahiro, saying that she smells very nice. Mahiro wonders if she does, as she just used regular old shampoo.

Momiji gets angry at Asahi and drags her away, despite Asahi's protest. She also tells Miyo to come as well, which causes Miyo to get aroused. Miyo says that she think's that she'll just go by herself, but Momiji points out that she was the one who suggested that that they go in groups. Asahi pushes Miyo out the door, despite Miyo saying that three people is too many. Asahi says that they might as well do it, and Mahiro notes that Miyo is still shy about being seen naked.

As Miyo lathers up, she feels very uncomfortable. She thinks to herself that being seen naked is bad enough, but in here Momiji and Asahi's gazes are like knives. She calms herself down by realizing that it is still worth it to see how the two act up close.

In the tub, Momiji remarks to Asahi how it's been a long time since they bathed together, noting that the last time was four years ago. Asahi mentions how they used to get so muddy playing youth soccer, and that they used to wash each other too. Miyo becomes extremely aroused by that last remark and tells the two that they shouldn't hold back on her account and to go right ahead.

Asahi is intrigued and gets out of the tub to wash Miyo. Miyo tries to point out that she didn't say her, she said each other. Asahi tells her that there's no need to be shy and starts washing Miyo's back. Miyo notes that it feels nice, and Asahi notes that her brother used to wash her back all the time.

Asahi tells Miyo that it is time to do her pits, and Miyo gets a bit confused. As Asahi reaches under Miyo's arms to clean her, she accidently gropes Miyo's oversized bust. Asahi is shocked by its size and compares it to her own flat chest, noting that it is a little shocking. Momiji is amazed that Asahi worries about that as well. Miyo is left in shock, and in her own innocent way thinks to herself that now she'll never be able to get married.

Meanwhile, Mahiro hears a knock on her bedroom door with a voice telling her to open it. It turns out to be Mihari who recommends that they set up everyone's futons while they're busy. Mahiro asks Mihari if she's sure that she should sleep in the same room as them. Mihari points out that the point of a slumber party is to sleep in the same room. She then asks Mahiro if she's planning to spend the entire night with her "dear old sister", to which Mahiro apologizes for the bath incident. As they set up the futons, Mihari tells Mahiro that she'll be fine as they both know that she wouldn't hurt a fly. Mahiro remarks that she'll never understand what Mihari sees in people.

Momiji and Asahi come back from the bath, fully clothed in their pajamas. Momiji is excited to see that they get their own futons. Asahi really gets excited and tries to take the one that Mahiro is laying down, causing Mahiro to tell her to get out of the way. Mihari asks if the bathroom was too small for three people, and Momiji says that it was fine. She mentions though there she guesses that there was one incident though.

Miyo enters the room, and she is revealed to be wearing a beautiful nightgown that makes her look very grown up, though she's very embarrassed about it. Mahiro tells Miyo how mature she looks, thinking of her as a freshly-bathed beauty. Miyo gets more embarrassed and covers up saying that she doesn't want to be looked at, much to Mahiro's surprise. Momiji asks Mahiro to just be gentle with her, and Mahiro wonders just what happened in that bath. Mihari finishes setting up, and leaves them to it. Asahi says goodnight to her, once again referring to her as "Dr. Oyama".

Asahi asks Momiji what she wants to do now. Momiji tells her to calm down, and suggests that they decide who's sleeping where first. Mahiro claims the normal spot that she sleeps on, leading to Asahi claiming the one next to her, over Momiji's protests. Momiji suggests that they rock-paper-scissors for it, for real this time. Asahi agrees and says that she'll throw scissors. Despite knowing what Asahi is going to do, Momiji accidently loses by throwing paper. Momiji slumps over and notes that overthinking is a sure way to lose against Asahi. Asahi makes scissor noises and notes that victory goes to the honest.

Momiji tells Mahiro to be careful with Asahi, as she's all elbows. Mahiro feels worried about that, but Asahi tells her not to worry and that it'll be fine.

Miyo suddenly creeps up behind Momiji and says that with that out of the way, it's time for the main event: girl talk. Mahiro is happy that Miyo has gotten her second wind, and Miyo notes that this is the best part of having sleepovers. Mahiro thinks to herself that she is a little reluctant to join in.

Miyo asks what they should talk about first, and Asahi decides to take the floor for their first discussion. Asahi decides to tell them a take that will chill them to the bone; the tale of the pillow-flipper ghost. She remarks that it is a creature that she has encountered many times. She further explains that it is said to appear at the head of the futon night after night, and that it steals pillows and places them under the victim's feet. Sometimes, it even flips the unfortunate victim all the way around.

Mahiro wonders if this is really girl talk, as that was just a regular ghost story. Momiji becomes freaked out and asks Asahi why she's telling scary stories. Mahiro points out that it wasn't that scary and asks Momiji if she was listening. Momiji covers her ears saying that she's not listening. Asahi turns to Mahiro saying that she didn't think that Momiji would get this upset. Mahiro is surprised that Asahi did that even though she knew Momiji hated scary stories, and thinks to herself that Asahi is a naughty kid.

Momiji pulls her pillow over her head and says that she's going to sleep, despite Asahi's attempts to say that she's sorry. Miyo feels bad as all she wanted to do was talk about who-likes-who. Mahiro silently laughs and goes to sleep, thinking about how Momiji is pretty cute sometimes.

In the middle of the night, while everyone else is asleep, Momiji starts fidgeting. She notes that she really has to pee, but doesn't want to get up thanks to Asahi's story and doesn't want to disturb anyone either. She ultimately decides to hold it in until morning.

Meanwhile, Mahiro realizes that she is cold and gets up, wondering what happened to her comforter. She notices that Asahi subconsciously took it from her while she was sleeping and is now spooning with it. Mahiro notes that Asahi really is a terrible sleeper and tries to grab it back, which fails as Asahi refuses to let go of it despite being asleep. Mahiro notes that she doesn't want to wake Asahi, but that she also doesn't want to catch cold either. Seeing Momiji sleeping, Mahiro decides that this is an emergency situation and that she therefore has a perfectly good reason for this.

Mahiro rustles Momiji awake. Momiji sees Mahiro's figure hovering over her, and becomes scared, thinking that it's the pillow flipper. Mahiro apologizes for waking her and begins to squeeze next to her saying that she's going to be joining her. Momiji tells Mahiro not to, and Mahiro discovers that Momiji wet the bed after being scared a few seconds ago.

Mahiro and Momiji move the ruined futon and Momiji's clothes to the wash. Mahiro gives Momiji a spare pair of pants while Momiji apologizes for all this. Mahiro tells her not to worry, as she had an accident recently as well. Mahiro notes that it is real sudden for girls, causing Momiji to get confused. Mahiro tells Momiji to leave everything else to her, and says that she can use her futon, being the guest and all. Momiji agrees, but asks Mahiro where she's going to sleep. Mahiro tries to think of something.

Meanwhile, Mihari is sleeping in her own room. Mahiro suddenly comes in with a pillow, causing Mihari to wake up and ask what it is now. Mahiro asks Mihari not to ask her to explain and gets into bed next to her. She says good night and goes to sleep, much to Mihari's confusion.

The next morning, the soiled futon is hanging out to dry outside. Mahiro takes the blame, saying that it is really embarrassing. Mihari believes that that could happen, unable to argue with it given her experience. Mahiro chucks it up to having too much juice after dark. Momiji silently tells Mahiro that she doesn't have to be her scapegoat. Mahiro silently says that it's fine, as they can keep it a secret this way. Momiji understands what really happened, but doesn't say anything, understanding that some things are better left unsaid.

Mahiro asks what happened to Asahi, and Miyo says that she is still asleep in Mahiro's room. Momiji remarks that Asahi sleeps deeply, so it's hard to wake her.

In Mahiro's room, Asahi is revealed to have completely flipped her body and pillows while sleeping. She wakes up, realizes what position she's in, and believes that the pillow-flipper was responsible.

It's also revealed that Mihari couldn't get any sleep as Mahiro cuddled up next to her in her bed the previous night.
