Today, a transfer student is coming.
Shortly before morning homeroom begins, the air in the classroom is lukewarm and unchanged. The spring sunlight streaming through the window glitters on the edges of the handouts scattered on the desks.
The homeroom teacher stands at the podium and clears their throat.
"Uh, I'll introduce a transfer student today. Come in."
The classroom door slides open. Appearing is a girl with a face so hard to describe and unmemorable. Black hair, black eyes—her height, build, and everything else seem to be the distilled essence of the concept of 'ordinary'.
"I'm Yamada! Nice to meet you all~!"
The air in the classroom wavers slightly. Some classmates offer vague smiles, while others slump over their desks.
