Before the Demon Choir teacher could even finish his opening remarks, Dekan had already walked over to the seats opposite the stage and sat down.
"Start singing."
He looked exactly like a judge, one hand propping up his chin as he leaned back in the chair.
His behavior caused the students of the Demon Choir to knit their brows.
Because the most arrogant part of Dekan's actions was—
He had placed the chair backward, positioning himself with his back entirely to the choir.
The music teacher was silent for a moment before saying, "...Then let us begin."
Since this student was so cocky that he wouldn't even grant him the chance to give an introduction, there was no need to explain the rules either.
After all, it was the student's own choice.
When the killing mechanism was triggered, he would simply follow the rules.
The music teacher sneered, turned his head toward the students of the choir, and began to play the large instrument in front of him.
This instrument looked like a piano and sounded like a piano, so Dekan simply treated it as a piano.
Well, except for the fact that the timbre was a little bit strange.
However, in Dekan's view, the timbre of a piano was never the most important thing.
What Dekan cared about was its structure—
It would be very suitable to be modified into a barbecue grill to place beside a swimming pool.
Amidst the accompaniment, the Demon Choir began to sing in perfect unison.
The style of the piece performed by the choir was quite clamorous and indulgent.
It was like the low murmurs of the fallen, yet also like the sighs of a judge, carrying an indescribable charm that seemed intended to make the listener sink deep and lose themselves within it.
In less than five minutes, they finished their first run-through of the song.
Until they finished singing, Dekan did not react in the slightest.
He had no intention of applauding at all.
Only his somewhat dissatisfied voice could be heard: "It is a pity that I cannot turn my chair around for you."
Dekan sighed and stood up.
"This is how the song should be sung. I will only teach it once, so listen carefully."
As Dekan spoke, he walked toward the stage.
This left the music teacher and the students of the Demon Choir both shocked and enraged.
They had never seen such an arrogant person!
Turning his back on them earlier was one thing.
Not worthy of making him turn around?
And he wanted to teach them how to sing?
What kind of newfangled insult was this?
He must be looking for death!
"Heh."
The expressions of many students gradually turned ferocious, and some even began to laugh.
In their eyes, Dekan was already a corpse.
Soon, they would make Dekan understand what true despair was.
To be cruelly killed amidst fear and unwillingness.
The music teacher also smiled with disdain.
He could not wait to kill this student who did not know the meaning of life.
The truly terrifying thing in this classroom was not the killing mechanism, but this group of demon students filled with twisted psyches.
They would use every possible means to kill new students.
"Are you ready?"
Seeing that Dekan had already stepped onto the Demon Choir's platform, the music teacher asked.
"Ready."
Dekan shouted along with the group of demon students.
The music teacher took a deep breath, placed his hands on the keys, and slowly pressed down.
The clamorous and indulgent timbre flowed slowly from the piano, gradually solidifying in the air.
The piano notes began to fall like raindrops, their echoes lingering across the stage.
Just as the piano piece was about to reach its crescendo.
And just as the Demon Choir began to sing.
"Wewerenostrangerstolove~"
Dekan's voice shook the music teacher's hand so violently that he nearly missed the next note.
All the demon students stopped their chorus, staring at him in stunned silence.
It wasn't just the piano; even the voices of the Demon Choir were completely drowned out by Dekan alone!
Why?
Because Dekan had taken control of the school's broadcast system!
He had cranked the volume of the music classroom's speakers to the max, using his magic ring as a microphone to belt out the song he wanted to sing!
"What are you looking at? You're all singing it wrong!"
"???"
The expressions of every demon student were filled with existential doubt.
Setting aside for a moment how this guy even understood their rules.
By what right could this bastard control the school's broadcast system?!
The volume was so loud it felt like it would shatter their eardrums.
How could they possibly outshine this jerk?
The demon teacher also stopped playing, his face as dark as a pot as he glared toward the choir.
"All twenty of you, you sang it wrong."
Though the music teacher hated to admit it, he had no choice but to announce it.
Because those were the rules; the Demon Choir had always used this mechanism to sabotage other demon students.
Conversely, if the Demon Choir were the ones sabotaged, the teacher had to acknowledge it just as he always had.
If the demon teacher defied the rules and the principal found out, he would be the one to die.
All the demon students looked at Dekan with expressions of extreme terror.
They had already realized that things were going south.
"Ahem, let's start over."
The music teacher coughed twice and said with a sense of helplessness.
Giving the students a brief moment to prepare, the piano began to play once more.
This time, the moment the piano started, all the demon students reached a tacit understanding.
They prepared to jump the gun, hoping to make Dekan mess up.
But Dekan had already anticipated the demon students' strategy and jumped the gun first, singing out loud.
"It's changed, ahhh~~"
Dekan tilted his head back, looking intoxicated as he sang with a brilliant smile.
Once again, only his voice filled the entire music classroom.
"All twenty of you, that's your second mistake."
The music teacher, looking to save his own skin, ruthlessly declared the result once more.
The demon students looked ashen.
This bastard! There really was no way to deal with him!
If they let him succeed one more time, the entire Demon Choir would be wiped out!
If things continued like this, they were doomed; they had to make a desperate final stand!
"Go to hell!"
Finally, a demon student, driven to desperation, prepared to lunge at Dekan.
With his hands in his pockets, Dekan sneered and activated Mental Interference.
The demon student's trajectory twisted violently, and he threw a fierce punch at the demon student standing next to him.
The victim, caught completely off guard, was knocked straight to the ground.
"Teacher! He's attacking another student!"
Dekan raised his hand, looking exactly like a model student standing up for justice, and shouted loudly.
"???"
The demon student who had thrown the punch was full of question marks, staring at his own hand in disbelief.
He had clearly intended to kill Dekan!
Why was his body refusing to obey him?
Before he could even figure out the reason.
The music teacher let out a sigh, his figure transforming into a shadow as he darted forward, reaching out to ruthlessly snap the neck of the student who had broken the rules.
Then, the teacher returned to the piano with an expressionless face and sat on the piano bench, seemingly preparing to begin the performance for the third time.
"Hehehe, students, harmony is the most precious thing, you know."
Dekan looked at the group of demon students with a meaningful smile plastered on his face.
His expression, three parts provocative and seven parts mocking, looked exactly as if he were telling this group of students: go ahead and make a move, you will only die faster.
