A vintage-style fantasy book cover illustration, size A4, featuring three teenage monster hunters in cartoon style. One boy with short messy brown hair holding a glowing dagger, another boy with medium-length black hair holding a wooden staff with glowing runes, and a blonde girl with a ponytail holding a magical map. All around 16 years old. They stand in a triangle formation with the girl in the middle. Behind them are shadowy, majestic monsters: a lion with flaming mane, a tiger with glowing rune patterns, and a dark jaguar with glowing blue eyes, partially transparent. The background is a mysterious forest in dark brown tones with golden light shining through. The title “Trisaka Monsters” appears in vintage embossed gold font at the top. Add a fantasy symbol logo on their clothes representing a secret monster hunting guild. Highly detailed, fantasy adventure tone, magical atmosphere.
