High-contrast ink linework with dramatic hatching, exaggerated facial expressions and distorted perspectives to evoke a psychological horror atmosphere, accented by stark screentones and deep spotted blacks. Panel 1 (Top Right, Medium Shot): A young schoolgirl with dark shoulder-length hair and straight blunt bangs stands rigid in a dimly shaded hallway. Caught mid-turn, her weight shifts back in uneasy hesitation, her hand hovering near her chest. A light dusting of fine vertical hatching crosses her forehead, and a tiny bead of sweat clings to her temple as her eyes dart toward the edge of the frame. A small square caption box at the top edge reads "放課後…誰もいないはずの教室で…". An oval speech bubble floating beside her reads "…え? だれかいるの…?" while faint, spindly katakana sound effects "ササッ…" scrape along the dark floorboards. Panel 2 (Top Left, Over-the-Shoulder Angle): Viewed from behind the girl's shoulder, looking past her trembling silhouette toward a slightly open wooden door at the end of the corridor. Her fingers clutch tightly at the fabric of her collar. Deep pitch-black shadows pool behind the door frame, stretching distorted cast shadows across the floor planks directly toward her feet. A jagged speech bubble beside her head reads "うそ…ドアが勝手に…!?" with elongated, shaky ink lettering "ギイイィ…" flanking the door gap. Panel 3 (Bottom Right, Low-Angle Close-Up): A dramatic low-angle shot focusing on the girl's face seized by sudden dread. Her round eyes stretch wide with pinpoint contracted pupils surrounded by dense, frantic radiating hatching lines within the irises. Heavy vertical shadow lines streak down across her brow and cheeks, and her trembling lips part in a breathless gasp. Crisp screentone contrasts against heavy solid blacks encroaching from the panel borders. A sharp-edged speech bubble reads "な、なに…!? 来ないで…!" accompanied by a bold, heavy-ink heartbeat sound effect "ドクンッ". Panel 4 (Bottom Left, Climax Panel): An oversized, climactic panel presenting an extreme, perspective-warped close-up of the girl screaming in absolute psychological terror. Her mouth gapes wide in an exaggerated shrieking oval with every tooth etched in sharp ink lines and dark cross-hatching filling the hollow of her throat. Tear droplets and sweat fly outward from her face, her eyes bulging with prominent lower eyelashes and dense under-eye hatching. Explosive black speed lines radiate outward from her head, obliterating the background into sheer ink force. A massive jagged speech bubble dominates the upper corner with bold text reading "ぎゃあああああああっ!!!", struck diagonally by dynamic, jagged brush-lettered sound effects "ギャアアアッ" vibrating across the panel boundary. Pure visceral terror.
