Fugu

Fugu (巫具, "Shamanic Tool") are inanimate objects that Shamans use as vessels for their Guardian Spirits. This can include weapons or any type of equipment that the user chooses to imbue with their Furyoku. Mastering the usage of one's Fugu is one half of forging a Shaman's Fujutsushiki.

Overview
All Shamans require some time of object to focus their Furyoku into to act as a medium between the Hidden World and the Human World. This connection allows Guardian Spirits to bond with Fugu, allowing Shamans to create their Fujutsushiki.

Fugu can be jewelry, accessories, weapons, or anything else the user may choose as a medium. The most effective Jugu are items that share a strong connection with the user and their Guardian Spirits.

Jugu that are constantly used and repeatedly infused with Furyoku will eventually develop its own "Spirit" giving off its own Furyoku. Fugu that give off high-levels of Furyoku are considered Sacred Relics among the Fujutsu community.
