The poster features Arisa, the main character, standing at the forefront with a determined expression. She is dressed in her navy blue sweater and black student skirt, with her long black hair flowing slightly as if caught by a gentle breeze. Arisa holds a stack of old, weathered documents tightly in one hand, while the other hand is slightly outstretched as if reaching towards the viewer or the mysterious elements surrounding her. Behind Arisa, the main building of Mae Fah Luang University looms large, its modern, conventional architecture bathed in the eerie glow of the setting or rising sun. The sky above is dark and overcast, with heavy clouds swirling, creating a foreboding atmosphere. Mysterious, glowing cryptic symbols can be faintly seen on the walls and ground around her, pulsing with a soft, ethereal light that hints at the hidden secrets of the university. In the background, shadowy figures dressed in dark, hooded robes lurk, their faces obscured, adding an element of danger and mystery. The mist from the surrounding mountains rolls in, partially veiling the scene and enhancing the overall sense of suspense. The overall color palette is dark and moody, with hints of blue and gold to highlight Arisa and the mysterious elements surrounding her.
