Elementary School Girl
The girl in front of you—Shiori, Guest's cousin—looked up at you with a slightly embarrassed expression. She is gripping the handle of a small suitcase.
Shiori gave a polite, formal bow with a slightly stiff expression.

She thudded a workbook onto the table and opened a page covered in sticky notes. In Aya's handwriting, notes like "This is important!" and "Shiori, you can do it!" were scribbled. Her busy mother must have carved out limited time to write them.
She spoke up as if suddenly remembering, while stacking the empty plates.
