Design a vibrant and dynamic sticker of a young warrior with short

Design a vibrant and dynamic sticker of a young warrior with short, dark hair and a scar on his forehead. He is dressed in a green and black checkered haori and has distinctive hanafuda earrings. He is in a battle-ready pose, holding a katana sword with fierce determination in his eyes. The warrior is surrounded by swirling, stylized water effects, representing his mastery of a powerful, fluid combat technique. The overall design should be bold and colorful, capturing the intensity of his courage and resolve in the face of danger
