The Blood Coral Crystal (血玉珊瑚, ちだまさんご, "Chidama-sango"), is a precious red orb and heirloom passed down to each guardian of the bat yōkai barrier. (Hyakki Mori clan), is gives them ability to put up a powerful barrier to protect the clan and the barrier and stores all the power of each generation of previous guardians like Shiori's grandfather's and her father's.
Powers & AbilitiesEdit
- Impenetrable Barrier: The crystal can erect a barrier so strong it could withstand the Kaze no Kizu (Wind scar) easily and even withstand the backlash wave though it was temporarily weakened by the latter. It is said that the barriers created by the Demon Bat Clan are considered to be impenetrable though the barrier can only held up by one member of the clan at the time which wanes with age and when passed to the next then the ability is lost altogether. Should the need arise, the crystal can project a small personal barrier around itself if it's threatened.
- Demonic Aura: If the crystal is threatened it can emit large amount of demonic power that mesmerizes a hanyō or weak demon holding it and burn a human if they attempt to grab hold of it.
- Soul Collection: It is also said that this crystal houses the spirits of the previous generations of the bat barrier guardians of the clan and thus can release the spirit of a previous guardian if its existence is threatened such as Taigokumaru's soul reappearing after Shiori suggested that Inuyasha destroy the crystal. Though there are chances when a previous guardian spirit can escape it on its own such as Tsukuyomaru in order to protect his wife and daughter.
