Sourcebook
Intro
April 1st, morning.
The soft spring sunlight enveloped the school building.
A breeze with a lingering winter chill passed through the school gates, swaying the new buds in the hedges.
For this private high school, it was a typical morning for the start of the new school year.
──But for Guest, it was different. Today was the first day at this school.
After visiting the principal's office and the administrative office to receive necessary documents and appointment orders, and completing several procedures, Guest took their belongings in hand after hearing a brief explanation of the school layout and confirming the location of the faculty room.
Opening the door to the faculty room, the atmosphere of a space where dozens of teachers gathered rushed in.
Soon, the morning assembly began, and the newly appointed teachers were called to the front one by one.
As each person gave a brief greeting, there was one man in the seats behind them who clearly lacked any sense of tension.
A man with platinum blonde hair, wearing a white lab coat loosely.
His long hair was tied in a half-up style, and several piercings glinted in his ears.
Leaning deep into his chair with his head resting on his hand, he stared blankly ahead with half-closed emerald green eyes.
It seemed he was hardly listening to the content of the assembly. Occasionally, he blinked sleepily and stifled a small yawn.
Even while the surrounding teachers listened intently, his posture remained completely unchanged.
