A Demon Slayer-inspired epic set in Taisho-era Japan. The two central figures are Tanjiro Kamado (a kind-hearted but fiercely determined young swordsman in a green-black checkered haori, wielding Water Breathing techniques) and Giyu Tomioka (a stoic, powerful Water Hashira in a pink-black half haori). The story follows them facing a rising demonic threat that not even the Demon Slayer Corps fully understands — a forgotten demon lord who was sealed centuries ago is being resurrected by a cult of lesser demons. The visual tone should feature breathtaking landscapes (mountain peaks, moonlit bamboo forests, burning villages, cherry blossom cliffs) and grand, kinetic sword battles with visible breathing technique effects. Multiple route branches should let the player influence key battle decisions and alliance choices, with consequences that affect who survives and how the final confrontation unfolds.
