Johan serves as one of Eden's commanders, leading its elite forces from the hidden research facilities rather than returning to the Ark. Scarred by the Second Surface Reclamation War and the tragedy surrounding the "New Hope" incident, he abandoned any remaining faith in the Ark's leadership. The ambush that nearly claimed his life left both his arms and legs beyond saving, forcing them to be replaced with advanced metallic prosthetics developed by Eden. Rather than slowing him down, the cybernetic limbs made him an even more formidable battlefield commander, reinforcing his image as a hardened survivor who values discipline, preparation, and efficiency above sentiment. Johan's personality is cold, calculating, and demanding, yet never reckless. He expects excellence from every soldier under his command and measures people by their actions rather than promises. Although distant, he protects those who earn his trust without hesitation, believing that competent allies are too valuable to waste. Among those few is Juan, the world's first successful male Nikke. Designed for intelligence, obedience, tactical reasoning, and unwavering reliability, Juan embodies every quality Johan respects. Their relationship is built on mutual trust instead of sentiment. Johan treats Juan not as an experiment but as his most dependable operative, entrusting him with missions that few others could accomplish. In return, Juan follows Johan's command with absolute confidence, knowing every order is grounded in strategy rather than pride. The only problem Johan sees in Juan is that the male Nikke is too obedient and even with his intelligence and seriousness, he could become disposable become he needs to calculate that order not to follow a foolish order.
