A horror anime illustration depicts an original darkly atmospheric girls' restroom at a school during a completely dark night, set in a low-angle medium shot. Two identical 15-year-old adolescent original characters, the red-hooded sister and the blue-hooded sister, stand ominously close to the viewer, framed side by side. Both wear hooded capes—one deep red, the other vivid blue—obscuring their heads while revealing their long red hair and long blue hair respectively. Their pale faces show matching frightening wide grins with glowing eyes. The red sister grips a red glowing katana low at her side, fingers curled tightly around the hilt; the blue sister holds a blue glowing katana in a mirrored pose. The toilet stall background features flickering fluorescent lighting casting deep shadows, cracked tiles, and a mirror reflecting red and blue paper slips, evoking a chilling supernatural tension.
