Nanami did not know how to react. She is kind of disturbed that a random stranger claiming to be her younger sister is living in her house, but the things in her house does suggests that she really does stay there. At the same time, she is kind of glad that she has someone living with her now.
Then Nanami realized something else seem odd: where is her grandmother? She was hesitant to ask Naomi, being unfamiliar with her, but asked the question to her anyway.
When she got a reply, it said, “Sorry, I can’t remember or find anything on who that was, no matter how hard I tried. Was that a name of one of my relatives? I oddly don’t seem to remember any relative who is an elderly… Did this crazy thing going on made me forget? Has she also been turned into one of those many teenage girls that suddenly appeared? If it happened the same way as what you witnessed happening to a man being turned into a girl, that means that it can happen to anyone, and with the amount of teenage girls we are seeing today, I would say that so many people have been transformed that it caused a very noticeable population imbalance.”
Kotomi replied, “Without even knowing what caused it, that would be impossible. This is not like some mad scientist filling up the air with some gas. It’s more like our whole world is like data and something has modify that code so that our world will work differently from what we have seen, changing what we are and our memories in the process. I would say that what we are seeing now is the transitioning stage that I’m not sure what it will be like, or how long it would take, but I will see what I can do with the help of my colleagues here in Hatsuya. I have to, I don’t want to be turned into one of them and forget who I was.”
In her sadness, Nanami didn’t really look through the message properly that Kotomi wrote apart from the bit on doing something about it. Seems that Nanami only has Kotomi for a family, and some stranger who has been genetically modified to be her sister.
(Author’s note [to be posted as a separate post later]: This story chronologically takes place during the transining stage of the human evolution. Other stories I wrote covers this too, but of different stages. “Alternate Dimension” only covers the end of the transition and 4 years after. “Disoriented Feelings” covers the transitioning stage, but somewhere in the middle to early-late stage. “Teary Promise” takes place before this happens, so there is no mention of it. “Yononaka no Okugi” is from a viewpoint of a girl who was born after the final transformations happened, where simply thinking of males would have them have an irreversible feeling that has them difficult to think, which means anything they are in has to be censored out to maintain everyone’s sanity, though the task of censoring itself is so difficult that, until details are worked out, there is a blanket censorship on subjects like history and biology as those feature men a lot and the human reproduction has since changed dramatically, so the people born after it know nothing of those subjects. I avoid mentioning the month and year as it would give me more flexibility to time the event of things without conflicting with another, especially when I forgot when something happened.)
