A top horizontal dark gray bar displays the white Japanese text "竜殺し". A soft watercolor-style anime illustration of a young man with short, messy blue hair, shown in a strict side profile against a light background of soft blue and purple washes. His face is turned exactly sideways, looking horizontally to the left, with both eyes not visible simultaneously. His gaze is directed straight ahead at eye level, with a slightly submissive, self-effacing expression. His eyes look sideways with a hesitant, uneasy quality, and his mouth is gently closed with a faintly downturned expression. His head tilts slightly downward, reinforcing his somewhat humbled demeanor. His body faces mostly away from the camera, creating a clear sense of turning. In his left hand, held low at his side, he carries a closed brown hardcover book. His right hand rests on the hilt of a long silver sword with a simple crossguard, the blade pointing downward. A brown scabbard hangs at his left hip. He wears a white long-sleeved shirt with visible dirt or watercolor stains, and dark blue pants. Soft white and blue light particles and delicate watercolor splatters float around him. The overall painting style features delicate linework, translucent color washes, and a cool, slightly melancholic atmosphere typical of traditional watercolor anime art.
