He is affectionately known as "Father" by his Neogene "daughters" and the orphans in his care. While a brilliant scholar and administrator in his youth, Furimizu has grown increasingly reclusive and secretive with age in his quest to acquire the Witchblade. Despite exhuberating charm and paternal warmth when interacting with the public and his "children", he is rather cold-hearted and deranged in reality. He is completely single-minded in pursuit of his goals, and shows no concern for the physical and emotional well-being of those who serve him. He's later revealed to be unable to have children. Believing his father to be perfect in every way, Furumizu comes to the conclusion that his mother's genes are to blame for his malady.
He attempts to create the perfect mother from his own "superior" genes which results in the creation of several genetically-enhanced women known as Neogenes. After selecting a candidate for the Witchblade among the Neogenes, Furumizu hopes to be reborn from the loins of the designated bearer as a superior being. After realizing that her "grandfather" views her as nothing more than a tool for his rebirth, a radically powerful Neogene named Maria mortally wounds Furumizu in a coup. As Furumizu chokes on his own blood, Nishida informs him that she purposefully neglected to incorporate his genes into the newest batch of Neogene zygotes. With his life's ambitions ruined beyond repair, Furumizu succumbs to a nervous breakdown. He wails hysterically over the loss of his "mother" and begins to ingest the vials containing the genetic material for the next generation of sisters. Disgusted by his unsightly behavior, Maria finishes him off with one last blow.
