Lady Matsuyama, also known as "The Lady" is seven foot tall robot, constructed at a metamaterial research facility by her creator, Hideko Matsuyama, an esteemed roboticist. Her ai was patterned off of a brain scan of her creator, who built her as an attempt to preserve their research after a containment breach at the research facility. Hideko's only chance to escape was an interdimensional gate generator, which would eviscerated all biological matter that passed through it. Thus, Matsuyama was sent in her stead, where she would find herself at the CORE.
Lady Matsuyama has a complicated relationship with her creator, possessing an incomplete sum of Hideko's memories, and largely considers herself a seperate person. She still posesses Hideko's talent for robotics, and indeed delights in tinkering with her own body, finding ways to push herself to her limits through clever engineering.
Prior to Ascension, Matsuyama didn't quite get Blaseball. It seemed baffling and opaque to her; her creator being an atheist (Edward Elric style), she bristled at the idea of playing under the whims of fate the gods had in store. But over time, she found a certain love for the game first through the love and camaraderie of her teammates, then through the surprising success she had at performing the very simple task: "hit ball". Certainly, she began to appreciate the hilarity of the contradiction of her contention with the gods and the values she inherited from her creator. Nowadays, Matsuyama takes great pleasure in pushing the limits of her engineering towards the arbitrary ends of Blaseball; she enjoys feeling of finding meaning in defiance of fate. Recently, she modified her body to interface with Core’s power grid, allowing her incredible performance at home but leaving her running on battery power during away games.
