Chapter 10: Mastermind
Ten years ago, Amano Hikari disappeared.
But it’s not just her, her whole class in the girls’ school had disappeared entirely. Furthermore, it’s on weekday.
Thirty people had disappeared from the school at daytime.
It naturally became news.
The police had began to search using several hundreds of people but there was no single evidence remaining.
It’s natural as they were summoned to another world with some paranormal power.
Though the event was reported for several weeks, the public’s attention was moved to a different location when there’s no progress appearing.
The police also gave up at the mystery of disappearance after one year.
The families also made a group to conduct their own investigation but a normal person can’t search out what the police hadn’t.
The activity became small gradually.
However, Miyuki still continued to believe.
Her gentle sister won’t just disappear by herself.1
She was young back then but her feelings of belief for her sister was strong.
Several years later, a letter reached Miyuki.
The paper was sloppy and there’s no name of the sender either.
「Could this be…!」
Though it’s a really suspicious letter, Miyuki was convinced that it’s her sister by just seeing the written character.
She went back to her room immediately and took out her sister’s notebook.
『It’s been a while, Miyuki. It’s me2』
「It’s really nee-san!」
Then she compared the characters and concluded.
『You may not believe it but I’m in the otherworld right now. It’s a fairy tale world』
Miyuki knit her eyebrows.3
『This letter is my special ability, and I can only send this thing to the former world once』
However, her body began to tremble while she’s reading.
『I have to defeat the Maou here. And, my existence in the former world disappears when I die here』4
The names of the students who have died have been written after that sentence.
「No way, I can’t remember them…?」
She looked through the letter a lot of times.
There are houses where Hikari had played from written in there.
However, she can’t remember the faces no matter how much she tried.
Miyuki continued to read while feeling impatience.
Then, she read something unbelievable.
『I might die too』
Miyuki’s body stiffened the moment that sentence caught her eye.
However, she continue to read ahead.
『We went to defeat the Maou but there’s a traitor among the allies. Her name is Nakusa Youko』
「Nakusa, Youko…that person!」
Fortunately or not, she was able to remember her face immediately.
In short, that woman betrayed her sister and is now living.
Miyuki felt anger rising inside her.
『She was on the side of the Maou on the last moment. A lot of companions have died because of that and I might die too』
「N-No way…I don’t want to forget nee-san!」
Unable to control her feelings, Miyuki gripped the letter.
『Though I felt embarrassed ignoring everyone and writing this letter, I’m glad I wrote this., Thank you for everything so far, Miyuki, I’m glad I was with you』
The letter was cut off there.
「Nee, san…」
Miyuki then crumpled the letter she’s holding.
However, she stood up and put it aside to valuables.
「I’ll definitely search for you」
Her eyes right now is much more determined than before.
Afterwards, she found Nakusa Youko what was with Hikari.
She lost her cool of course but only Hikari is the one reported.
The remaining students have disappeared completely.
The announcement of the police is that they are supposed to be kidnapped by a mystery man.
It was the whole female class before but it’s not impossible to be a case of two high school girls.
Miyuki can’t believe it naturally and went to meet Youko directly.
She was in the hospital and was being examined.
