"That's what the 17th Kuzunoha Shiki figured too back in 1560. Make it small. Harmless. His template was a hinotama - which you should know, has only light, no real flame to speak of. It can't grasp anything or hurt anything.

That little shikigami just disappeared one day, no one knows where to.

The next day, Nobunaga Oda would go on to take the head of Yoshimoto Imagawa and initiate a two decades long reign of terror.

Now consider this. The most threatening military technology at the time were muskets."

Naito was too quick to forget that a shikigami with all the knowledge of the Kuzunoha head honcho also had access, indirectly, to the wisdom of a millenia-old fox.
