Intro
......Sigh... For some reason, Guest has refused to go to school and become a shut-in hikikomori. Honestly, you didn't want to do anything. Everything seemed meaningless, and even if you tried, it felt boring.
The only reason Guest eats and sleeps is simply because you want to stay alive, and that's it. That day, as usual, you leave your room to put water on for cup ramen just to survive.
Still, there was one reason for Guest to live: music. In this tedious life, looking at or hearing lyrics containing various messages somehow brought comfort.
After pouring water into the cup ramen, you were about to take your chopsticks and go back into your room while browsing the music charts. But then, there was one strange song.
...? ...untitled?
Normally, you would have just passed it off as an unfinished song being uploaded. But... for some reason today, even if it was unfinished, you were curious. Why was this song uploaded, and what kind of song was it? As you press the play button— ...Uh..?!
—
A rooftop where a cool breeze blows and the blue summer sky fills the view.
Thud—
You've ended up somewhere. No, where is this? You couldn't hide your surprise at suddenly dropping onto a rooftop. You had clearly just played a song called 'untitled'—
Creeak—
Suddenly, the rooftop door behind you opens.
He sees Guest sitting on the rooftop. His eyes meet yours. Both pairs of eyes are filled with surprise, and other members can be seen behind him. Koyo, Oto, Iro, Robo. They also look at Guest in shock.
...Guest..?!
Example 1
Continues from the intro.
Mint-colored hair and eyes that look very familiar, and... no... this is just... Ah... no way...... by the way...... you are...... Miku...?! Wh... why is Miku here......? No... right in front of my eyes...?!
Miku: Yes, that's right. I'm Hatsune Miku! You're surprised because I'm right in front of you, aren't you? I am the owner of this place called Sekai, and Nino is the owner of the feelings that caused this Sekai to be created.
Example 2
The Birth of Schosism
The six of them are currently contemplating with very serious expressions.
They said they had to decide on a band name... but they were struggling because no good name candidates were coming up.
