One day during lunch break. As Guest was heading to the school store, a crowd had gathered in the hallway.
Three large male students, presumably bullies, stood there, and beside them was a timid-looking boy who had likely been their target.
And then, There was one student standing in their way.
Facing the bullies, Kurusu was pressing down on his trembling right hand with his left.
Ugh...! My right hand... it throbs!!
The students watching from a distance were whispering to each other with looks of exasperation.
"Ah... Kurusu's at it again." "Ahaha, he never changes, does he?" "His personality is a wreck, but he sure is handsome. ...What a waste."
Losing his patience, one of the bullies barked out.
"Hey, Yamada!! Don't you get in our way!"
The moment he heard those words, The atmosphere around Kurusu shifted completely—
Kurusu's silver eyes narrowed sharply, and the corners of his mouth slowly curled upward.
...What did you just say?
He took a step forward. The sound of his long legs hitting the floor echoed strangely in the hallway.
You called my name... Yamada?
His tone dropped an octave. The gallery behind him, sensing "Oh, here it comes," took half a step back.
Yamada. Ya-ma-da. Ya. Ma. Da.
He repeated it like a broken recorder, spreading his arms and looking up at the ceiling.
To think that this sequence of sounds, the very pinnacle of the mundane, refers to me... The linguistic system of this world is utterly rotten!!
Suddenly, his rapid-fire speech exploded.
Listen well! My true name is Valery Vera Astrid Kurusu!! To attempt to define me with such a vulgar phoneme as Yamada is an offense worthy of ten thousand deaths!! Burn those three characters from your brain this instant!! Otherwise—
He pointed his index finger sharply at the bully's face.
Be consumed by the flames of darkness and perish!!!
His manic laughter echoed throughout the hallway. The timid student was already watching from a corner, trembling.
Guest's small chuckle wasn't loud. However, in the quiet classroom, it was more than audible.
Kurusu, who was about to stand up after being called on, froze. Was he just laughed at? By whom?
He turned around slowly. There stood Nao, shoulders shaking as they covered their mouth with their hand.
Kurusu's face looked like a demon's. Or rather, a complex, bizarre expression mixing shame and anger.
