2B (YoRHa No.2 Type B), protagonist of NieR: Automata, is depicted here not as a character in action, but through a technical design study focusing on her lower limb mechanics. The image presents a schematic breakdown of her robotic leg and foot, including side (側面) and front (正面) views, with annotations in Japanese detailing hydraulic systems and joint articulation. This digital illustration reveals the intricate engineering behind her android form, emphasizing the industrial-aesthetic and futuristic design central to the PlatinumGames and Square Enix universe crafted by Yoko Taro. As fan art, it offers a rare, behind-the-scenes look at the character's construction, appealing to enthusiasts of NieR: Automata's world and mechanical design.
