A dramatic Japanese light-novel cover illustration in high-detail anime fantasy style, square composition, showing a heroic ensemble posed for battle in a ruined mountain pass at sunset with cherry blossoms blowing through the air. The scene centers on {argument name="hero title" default="Momotaro"}, a young black-haired male warrior in glossy red samurai armor, crouched in the foreground and gripping a katana diagonally across his body. Beside him in the front-right foreground is a black-haired young woman in matching red armor with a high ponytail, also drawing a katana in a dynamic combat-ready pose. Around them stand 5 additional companions for a total of 7 characters: 1 brown-haired short-haired girl at front-left holding a short blade, 1 silver-haired angelic woman at upper-left with large white wings and a drawn bow, 1 tall red-haired warrior at top-center carrying a large weapon over the shoulder, 1 long straight black-haired shrine-maiden-like girl at upper-center-right in white and red with light armor, and 1 blonde girl at right holding a large ornate war hammer. Add a distant Japanese castle on the right background, jagged rocks and broken ground, glowing embers, drifting petals, and a luminous cloudy sky with strong backlight behind the group. Use cinematic fantasy lighting, epic adventure mood, polished painterly rendering, sharp detailed armor, flowing hair, layered depth, and a bold heroic poster feel. Include large Japanese title text across the top in metallic gold with black outline reading {argument name="top title text" default="《御伽話ファンタジー》シン・桃太郎伝"}, with a smaller Japanese subtitle beneath it in white with dark outline reading {argument name="top subtitle text" default="~追放・転生した元神は、おとぎ話の世界の美少女たちと世界を救う!!"}. Include large Japanese promotional text across the bottom in bright red with white outline reading {argument name="bottom catch text" default="追放、転生した神・桃太郎。御伽話の美少女たちと試練乗り越えて鬼退治!"}. Make it look like a commercial fantasy web novel or manga cover image, energetic, crowded, and visually striking.
