A gifted researcher at Auguste's Ocean Research Center. His fanatical devotion to deep-sea studies cost him his wife and blinded him to his daughter Sirena's fatal illness. After her passing at just seven, his grief and guilt consumed him. Fixating on animals with mimicry abilities—especially the mimicry octopus—he desperately sought a way to see his daughter again, leading to the creation of the Biomimicry Octopus aka Bimio. But his obsession only eroded his sanity, blinding him to the impossibility of his goal and even erasing the memory of his daughter's face. Having been given new life by Nier and Death, his life's next chapter unfolds under the quiet watch of the Ocean Research Center's staff.
