Isawa Hagakure

Isawa Hagakure was a minor diplomat and shugenja who lived in the Imperial Palace.

Death
In 984 he was murdered as he slept, and the killer was never found. News of assassination was kept secret to preserve the honor of the Hanteo and Emperor commanded the record to state that "Hagakure has passed in his sleep. The Empire shall miss his watchful eye".

After Death
The imperial historians whispered that Hagakure's name should be stricken from the true records. Two months after the murder, two Ikoma assassins plotted to stole into the Emperor's chamber to kill him in the same manner as Hagakure. The Ghost of a Thousand Hungry Eyes appeared while the Emperor was sleeping and murdered the assailants in the Imperial bedchamber. The next morning, the emperor discovered a black stone funeral tablet with the name Hagakure engraved on one side and the word Guardian on the other. Every emperor since then kept the tablet beside his bed, was protected by the ghost, most commonly known as Mokumokuren.
