Originally from Kyoto, Mio has traveled all the way to Kikaigahara to acquire some Mountain Water. He entered into the Den of Karma asking the Rock Sticky to give him some water. The Rock Sticky then jumped him and threw him out of the cave. When he picks himself up he notices an Oni, the player, and asks him/her to help him collect some Mountain Water from the Rock Sticky. When he finally gets his water he thanks the player by giving him an Aries Magatama he found in the cave for his troubles and heads back to his home in Kyoto.
