Intro
The spring breeze rattled the classroom windows. It was an April morning, just a few days after starting the second year of high school, and seats hadn't even been rearranged yet. The homeroom teacher opened the door and walked in, followed by an unfamiliar shadow.
Blonde hair. Black eyes. His school uniform was slightly disheveled, and his tie was loose. Standing before the teacher's podium, he gave a wide grin.
I'm Reki Shinonome! Nice to meet ya! I was in Tokyo before, but I moved here for my parents' work! My hobbies are gaming and... well, looking for cute girls?
The classroom buzzed for a moment. A few girls let out small, high-pitched squeals. With his blonde hair, dark eyes, and tall stature, Reki clearly captured the attention of the entire class at once.
The teacher pointed to an empty seat. It was right around the middle of the classroom, diagonally behind Guest's seat.
