canned coffee"Emerge from darkness, blacker than darkness, Purify that which is impure."

　The bright sky darkens as Higuruma makes a sign with one hand and lowers the curtain.
　Nanami is next to him as he steps into the abandoned school.
　
　The school, which lost its role some time ago, is empty and quiet.
　The two of them walk up the stairs to the classroom where they are told the crime scene took place.

　They find a sign that reads "Music Room" and enter.
　At the end of the classroom, there is a piano with sheet music on the top.

　The words "Bach Bell Canon, Elementary" are printed on the front.
　When opened, it is not that long.

　Nanami puts the sheet music up, then opens the lid of the keyboard, pays off the chair in front of her with her hand a little, and sits down.

"Since the school was closed, when I play the piano here, I get a curse when I finish a song. ...That's what you said, wasn't it"
"Hmm... that's what I heard."
"It's been a while, but I'll play it."

　Slowly, Nanami takes a glance at the sheet music, then begins to play the piano.
　A melody begins, not difficult by any means, and Higuruma listens.

　After a few moments, Higuruma stands alongside Nanami, who sits down, and begins to play the accompaniment an octave higher.
　Nanami looked surprised for a moment, but continued to play.

　Nanami finishes playing the main melody, but the repetition comes again.
　He signaled to Higuruma with his eyes, and the melody was repeated in a different octave.

　As he finishes, a black haze gathers from the pictures of the musicians on the wall and takes shape.
　The two men take their weapons and brace themselves.

　The spirit has the face of a young girl.
　The rest of her face is a swollen, undulating black mass.
　She speaks to them.

"I envy you."

　They do not answer.
　The girl continues to speak.

"I always wanted to play with someone. No one played with me. I was alone."
"I envy you guys."
"But then I thought, 'Enough is enough.
"I'm tired of waiting. I want to disappear."

　Nanami stares at the girl's monologue with tears spilling down her face, and asks.

"I will purify you."

　Nanami slashed at the girl who gave a small nod.

　...The curtain is released, and the two of them go outside.

　They walk in silence, refusing the assistant menber's offer to take them home.

　They buy canned coffee from a vending machine on the way.
　Higuruma takes out a cigarette, Nanami takes one, and they both light up.

"So...you've been piano playing too, Hiromi."
"A little bit."
"...I'm sure I could have saved her."
"Yes, probably. I hope so."

　Neither of them said anything more, swallowed the bitterness of their canned coffee and exhaled the smoke from their cigarettes.

　The curtain of nature is beginning to fall around them.
　They finished their coffee, put out their cigarettes, and headed home.
