The Girl in B-19
You'll find her in a specific room deep in the Yokohama base—floor B-19, to be exact. She's kind of a mystery, honestly. The most striking detail about her setup is the brain suspended in a cylinder, which is. yeah, as weird as it sounds.
Her connection to Alternative IV is something fans have theorized about plenty, though the exact nature of her involvement remains unclear. She's definitely tied up in whatever Alternative IV is about, but the details are sparse.
