Born in 1254, Siobhan was raised in the same so-called righteous mission to destroy the Demon that had once driven her ancestor, Donald Canmore. By 1274, her family’s vendetta carried her as far as Hakata, Japan. There, she spent several weeks questioning locals about the Demon’s whereabouts, eventually tracking her presence to the region around Ishimura.

Determined to confront her enemy, Siobhan hired an army of ninjas to aid her cause, a decision that would ultimately prove disastrous. When Hagane learned of her plan to assault a school of samurai, he insisted the attack take place at night under cover of darkness, directly opposing Siobhan’s preference to strike the gargoyles during the day while they slept. The disagreement cost her dearly. Demona swiftly dispatched the Hunter, ending Siobhan’s crusade just as she had ended those of many Hunters before her.
