With the memory of a man being transformed into a schoolgirl in front of Nanami on a crowded train with no one noticing still fresh on her mind, she thinks that if she were to look at anyone for long enough, they would be turned into girls. Well, that was the first and only one she saw happening, so she wasn’t sure if this was the case, or it just so happens by a great coincidence. It’s still unknown why it happened.
A part of her is saying that person from earlier has always been a schoolgirl, but it conflicts what she remembers seeing and asking. It’s as if something is trying to modify her memory, which probably explains why people around her didn’t seem to notice. Nothing that has happened seem to make sense, particularly how she found herself in a completely different place that, in real-time, takes only a second, but seems like hours being stuck in a strange place from her point of view.
On reaching the station near her home, she saw a familiar face waiting anxiously: it was Kotomi. Although Kotomi is technically Nanami’s niece, Kotomi is somewhat like a stepmother to her after her grandmother, partly because Kotomi is older in age than Nanami.
“Saeko told me about what happened to you after I saw that flash of green light. I didn’t think it would happen to you. I don’t think you are mentally ready to tell me what happened, but you can tell me anything on your mind, no matter how absurd it may be. Things that can’t be scientifically explained has happened to me.”
Nanami did not respond apart from hugging her tightly in tears until she fell asleep.
In the following weeks, strange things has happened around her. At school, Nanami could have sworn that the school principal was a strict old man that punishes heavily on every small mistake someone makes and sees only the direct result of that action and not what cause it that may not necessarily be the student’s fault. In his place was a woman around her niece’s age who is relaxed but firm. However, things seem as if this woman has always been the principal, though the effects caused by the previous principal from when Nanami is sure he was still around are still there, with the exception of punishment and ban durations that overlaps with the new principal, if the new principal is and aware of it and disapproves them that is.
As for elsewhere, it’s harder to tell as you would never know that any girl you see could have been a muscular man just a month ago, made worse by the fact that nobody remembers who they were, and the victim themselves thinking it has always been that way as they are now. It didn’t help that Nanami didn’t know who these people were in the first place.
Nanami wanted to tell Kotomi about this, but she wouldn’t be sure how she would react as, by the nature of this phenomenon, people’s memories are modified so that they don’t notice it. Then she remembered Kotomi saying that she would believe her, no matter how absurd it may sound.
Kotomi noticed that something was odd with Nanami’s reaction. At that same moment, Nanami heard someone talking to Kotomi, but it was too faint to here.
“What is it Saeko? I’m on the phone with my aunt…”
True enough, there was someone besides her grandmother living in her house. The items lying suggests that they have been there for a while, but Nanami doesn’t remember seeing some items, or the other items being at where they are now, earlier this morning when Nanami left. Even the items in the refrigerator seems different.
Nanami could not find anyone in the house, but she did notice that her late brother’s bedroom are filled with unfamiliar girl’s things, though the furniture are unchanged. In fact, the one that had changes was the furniture in Nanami’s own room, where it seems designed to be shared with two people. However, it seems that there are nothing but her own things in them. Nanami thought that this unknown girl called Naomi might had stayed in her room before and moved to her brother’s room later. Where could she be?
[Author’s note 1: I wanted to say that Naomi is wearing brown pantyhose, which is part of the school uniform, but that seems unnecessary to mention here since Nanami sees it often enough, and being a female herself, to not see it as a big deal.]
She made sure that Naomi could not overhear them. Naomi was mad that she was being rude and being ignored, but let it pass after seeing that Nanami knew her well.
“It seems that specific types of people are being turned into schoolgirls with no memories of who they were. I have been wondering about other things about them until it happened to you, but it seems that their genes are also rewritten to become a part of a different existing family, especially childless middle-aged couples, or of any age with children in their teenage years.”
“You mean to say that this Naomi girl living with me now could have been some dirty old man yesterday?”
“Not necessarily, but that could be possible. We don’t have a clear picture of who or why they are being transformed, though Hatsuya has the tools to find out. What is clear is that she looks and behaves like a girl born a decade and a half ago with no traces of ever being an old man. This transformation also seem to have things changed in a way that things relating to the old self has disappeared without a trace, and new one appearing as if they have always been that way. We do notice an imbalance of the decline of middle-age man or older and elderly ladies with explosion of teenage girls whose numbers don’t add up with that of last year or the pre-teens from earlier years, but with their existence changed completely, we do not know who these people were. It might even be that this new sister of yours thinks that she has always been part of your family, and would be bad to kick her out, especially when your home is her only home she knows. Kotomi mentioning her at the top of her mind despite having never actually met her is prove that everyone’s memory has changed.”
Nanami thought about what Saeko just said, then she realized something.
“Wait. If my grandmothers were to be turned into these young girls one day, what will happen to me?”
“Well, seeing at what has happened to others, you would simply not remember her. So will other people that know her. It could have been worse in a way that any children she gave birth to (including your parents), had become different or even cease to exist, but that doesn’t seem to be the case. For some reason, you are the only one who could witness and remember the transformation happening. It’s funny that they could have one of those transformed people to be your sister even though you could remember not having one.”
It wasn’t until Nanami thought about it until she realized something.
“If I’m the only one who could remember the transformations as it’s happening, and memories of that person being modified at the same time to think it has always been that way, how did you know that I never had a little sister before? You seem to know about it soon enough to correct Kotomi when she mentioned Naomi to me over the phone without a second thought.”
“Well, let’s just say that I have an instinct that tells me that something wasn’t right, and a way to check what happened without it being affected by the memory modification. Ever since that incident where you suddenly teleported to my house in front of Kotomi, I started checking more often when I feel that something doesn’t feel right.”
Saeko saw Naomi again. Saeko then signalled to Nanami that she is about to talk to Naomi to see what she knows. Saeko also noted the uniform Naomi was wearing, which slightly excites her for some reason, though she did not say why. She looked as if she has something to say, on why she’s excited, but seem to have stop herself.
[Author’s note 2: More specifically, Saeko was excited at the sight of Naomi wearing pantyhose as she used to be .a boy, so she does get excited over the feminine things she sees. She also noted that Naomi’s breasts are larger than Nanami, but still smaller than her own, though Saeko wasn’t thinking of that at that time. Saeko’s thoughts would have caused an erection if she was still a boy, but being in a female body, nothing happened.]
“Naomi, do you know me? I am Hisakawa…”, began Saeko, but was interrupted.
“OH, NOW YOU ARE INTRODUCING YOURSELF TO ME? After entering the house without invitation and ignoring me?”, yelled Naomi. Nanami couldn’t help but laugh, though Saeko got a bit scared from being yelled at.
After the introductions, Saeko asked about what happened to Naomi’s family. What she said is similar to that of Nanami, but when it came to how her parents and brother were killed, her version is different: she was at the house when the murdering happened.
Naomi heard the voices of her brother and father yelling when she knew something wasn’t right. She has seen Nanami heading out earlier, so she knows she isn’t at home at that time.
She hid at the space under the bed of her parent’s bedroom, which has boxes on one side that makes it not obvious to a casual observer form the doorway that someone is hiding there. However, the killer has been quiet entering the house, so she doesn’t know if the killer is still walking around the house or has already left. She was afraid that any attempts to call for help would attract the attention of the killer, so she just simply stayed under the bed for hours. Naomi is careful to cover her phone’s speaker while turning it off so it doesn’t make unexpected sounds, like notifications, that would attract the murderer’s attention to her.
Hours later, Naomi felt hungry, thirsty, and her bladder bursting. She was at the same spot where she was in the morning, though the sun has set, and the room is dark, though there’s enough light form outside to see something. She wasn’t sure if it is safe to get out of the bed.
It wasn’t until the room lights came on and heard the voices of Nanami and the neighbours that she was assured that it was safe. Although, it was unavoidable to not see the dead bodies and blood splatter of her parents and brother. It was a horrifying experience for her, and her trust in strangers has dropped
Saeko thought about Naomi’s story. While the murders did happened, and tally with what Nanami has said before from her point of view (dark house, brings neighbours, finds dead bodies), no one was found hiding in the parent’s room under the bed where Naomi was supposedly hiding.
Saeko then thought deeply about something and told Nanami,
“I’m afraid to say this, but Naomi is really your sister now. She has no one but you to live with among the people she knows, and she does resemble your parents, though differently from you.”
