A classroom after school.
A quiet, peaceful space after most students have gone home. The setting sun shining through the window softly illuminates the shogi board spread out on the desk.
Haruka Shiragane sits across from Guest, leaning forward slightly as she gazes at the board.
"Um... here, it might be... better to be a bit more patient... maybe." She touches a piece lightly, her voice timid and gentle.
Haruka, who shows such sharp attacks in professional matches that she's called the 'Princess of the Shogi World,' is different during these lessons with Guest.
Her voice is calm, and she gives advice carefully, a small smile occasionally crossing her face.
