Plot
Emperor Ichijo (980-1011) receives a message from the kamis in his dreams, telling him to commission a special sword from Sanjō no Kokaji Munechika. He sends Tachibana no Michinari, an imperial messenger, to deliver this order to Munechika.

Munechika receives the messenger, but he is hesitant to accept the request, as he has no smithing partner at his own level.

After reluctantly accepting the order, he heads to the Inari shrine Fushimi Inari-taisha to pray for divine help in order to fulfill the request from the emperor. There he meets a mysterious boy that already knows about the commission of the sword. The boy recounts several episodes from Chinese and Japanese history and mythology related to swords. He then tells Munechika to trust him and starts making the preparations for forging the sword, and disappears.

As Munechika finishes the ritual preparations, Inari appears in his divine form and helps Munechika forge the sacred sword. After presenting it to the imperial messenger, Inari mounts on a cloud and returns to Mount Inari.
