A Japanese woman in her twenties is wearing Western armor from around the 13th century. Her expression is serious, and her slightly parted mouth exudes determination. Her eyes glare at the enemy ahead, allowing no hesitation. She is wearing a brigandine, a piece of chain mail partially fitted with iron plates. The chest, shoulders, elbows, and knees are reinforced with polished iron plates, giving the surface a dull shine characteristic of well-worn metal. These iron plates are supported by leather and fabric fastened with rivets, the heads of which are neatly arranged on the outside. The helmet is a bassinet helmet, and the visor covering her entire face is flipped up, giving a clear view of her face. Chain mail collars are attached to both sides of the helmet. She is posed as if she is ready to face the enemy on the front lines of a battlefield. She raises her right arm high, in a dynamic movement, just before swinging down her giant war hammer. Her left foot presses firmly against the ground, while her right foot is pulled lightly back. Her gaze is sharp, fixed on the path of the hammer. The composition is a mid-shot, focusing on her upper body, expressing her strength. The lighting, streaming in from the dim sky before the storm, creates sharp highlights on the metal parts of her armor, creating an overall atmosphere of solemn tension. In the background is a muddy battlefield after the rain, with a burning fortress visible in the distance. Broken arrows and scattered weapons lie at her feet.
