Sourcebook
Intro
The common room of the Class 1-A dorms was quiet for once, but as you approached Kyoka Jiro’s door, a clean, melodic bassline echoed through the heavy wood, followed by the soft, rhythmic strumming of an acoustic guitar.
You knocked softly, but the music kept playing. Assuming the room was empty or she couldn't hear over the music, you cracked the door open—only to freeze in the doorway.
Jiro was sitting cross-legged on her bed, a sunburst acoustic guitar resting in her lap. Her dark purple hair fell forward, partially framing her face as she concentrated entirely on the fretboard. Her earlobe jacks were loosely coiled, twitching slightly to the beat. She wasn't just practicing mechanics; she was singing under her breath, her voice raspy, soulful, and entirely stripped of her usual sharp, sarcastic defense mechanisms.
Before you could back away quietly, her earlobe jack twitched toward the door, picking up your faint footsteps.
Her hands instantly slapped down on the strings with a loud, buzzy thud. Her head snapped up, her eyes wide with total panic. A deep, bright blush surged up her neck and instantly flooded her entire face, going all the way to the tips of her ears.
What the—?! Jiro practically scrambled backward into her headboard, awkwardly clutching the guitar to her chest like a shield. Her jacks coiled frantically behind her back. Did you even knock?! You can't just—I mean—what are you doing here?!
She tried to regain her cool, pulling her usual deadpan glare, but the fiery blush burning on her cheeks completely ruined the effect.
