I'm just going to post Furinkan's note here:

"[The shikigami] calls the spear that he is carrying the "Spear of Taima".
The Spear of Taima (退魔の槍/Taima no Yari) uses the word "taima" (退魔), a term that is often used in contemporary fantasy literature meaning "demonic exorcism". However, despite the word's modern popularity in fiction, the word is of ancient origin dating back to the late 1500s when the historic figure Ishida Mitsunari (石田三成) was said to have defeated a demon that haunted a bridge."
