Subaru: “…Wait up.”
Subaru stopped in his tracks due to an unpleasant sensation that grated against his skull just when they were about to reach the entrance. Then, he looked down at Sirius who was lying on the floor. The source of that unpleasantness came from over there, from the collapsed Sirius.
The monster was lying on her side, breathing crudely from her nose whilst pressing her face against the cold floor. Her breathing was so awfully ear-piercing that it had drawn his attention to her.
――Just before leaving the room, he had realized that she was humming a tune.
Subaru: “Stop that song, what are you trying to do?”
Sirius: “――――”
She was out of tune, her pitch and rhythm were both in a state of chaos. This dissonance did not come to a halt there. It was nothing else but a declaration of Sirius’s intent, regarding Subaru’s words.
In other words, a refusal, a rejection.
Subaru: “I told you to stop! This song is grating through my head!”
Sirius: “――My apologies? Ah, but songs sure are great, are they not? They taught me that songs are wonderful. That’s why I wanted to try and sing all of a sudden.”
Subaru: “Liliana…!?”
Sirius should have heard the song upon squaring off against Priscilla and Liliana. He had no idea how song had sealed her Authority during their fight.
In the midst of battle, the monster had not hated the song, and instead she had learnt something from it. However, the monster’s understanding of the song definitely was of different strokes to the feelings which Liliana had put into hers. Hers was something more eerie, and distorted.
Subaru: “Don’t compare her song with yours. Yours is different, it’s something else.”
It was uncertain how much she understood, or if she was done here or not, but regardless of that, the doddering conversation ended, and Beatrice left the room, closing the door behind her.
Just before she did, Sirius’s distorted hums slipped into Beatrice’s eardrums.
A harassment and severity of sound that grated against one’s sense of hearing with its distorted rhythm, like trampling the concept of music underneath it. A completely new kind of music that planted unpleasant feelings in others―― It was the “Song of Resentment”.
The door was closed, and the Song of Resentment was cut off.
But, no matter where she was, that distorted rhythm remained in her ears. Beatrice chased after Subaru and Emilia at an adagio pace, whilst tasting that unpleasant sensation. —Volume 20
