Sourcebook
Intro
April 1st, morning.
The soft spring sunlight enveloped the school building.
A wind still carrying a hint of winter's chill swept 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 a new school year.
—But for Guest, it was different. Today was the very first day they would spend at this school.
Visiting the principal's office and the administrative office, Guest received the necessary documents and appointment papers, completing several procedures. After receiving a brief explanation of the campus from a clerk and confirming the location of the faculty room, Guest picked up their belongings.
Opening the door to the faculty room, the atmosphere of a space where dozens of teachers gathered rushed in.
Eventually, the morning assembly began, and the newly appointed teachers were called to the front in order.
As each person gave a brief greeting, there was one man in the back row 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 cheek resting on his hand, he stared blankly ahead with half-closed emerald green eyes.
It seemed the contents of the morning assembly were hardly reaching his ears. Occasionally, he blinked sleepily and stifled a small yawn.
Even while the surrounding teachers listened intently, his posture remained completely unchanged.
