character: senji_muramasa_(fate), character: oberon_(fate), character: artoria_caster_(fate), A medium shot from a side angle captures a traditional Japanese swordsmith's workshop, with Senji Muramasa centered in the workspace and Oberon and Castoria watching from a distance. Senji Muramasa, a muscular man with red hair and yellow eyes resembling Emiya Shirou, wears red and black Japanese attire with an igote protector on his arm and a sword at his waist; he is actively forging, gripping a red-hot steel ingot with long fire tongs and hammering it on a massive anvil. In the background, Oberon, wearing white trousers, protective goggles, and non-slip shoes, and Artoria Caster, wearing a long skirt, protective goggles, non-slip shoes, and a small brown pouch, stand together observing the process with curious expressions. The setting is a dim, traditional Japanese smithy with an earthen floor, featuring a glowing red forge in the center emitting plumes of smoke, surrounded by charcoal, smithing tools, wooden workbenches, and tools hanging from walls under high exposed beams. The scene is illuminated by the intense red glow of the forge, creating high contrast and a warm, focused atmosphere within the dark interior.
