Ok, same comment for this what I commented on ”parent”...
I am convinced that Komachi would fit for role of ”Tuonen Tytti” (”Daughter/Maiden” of the Lord of Tuonela; aka Finnish ancient equivalent of Sanzu River) in one version of Finnish rune song telling a tale of ”birth of iron”:
Here is my check list from the song: 1) Tuonen Tytti falls asleep on a fine pat h of grass (Totally like Komachi!) 2) ”Forgot her bosom open” (aka bosom exposed, wouldn’t be unbeliavable with those clothes...) 3) ”Utareista uhkuvista” (Errrrrm... translated as ” udders grabs/gorgeous/voluptuous/etc”) (And yes, ancient Finns were very straight with their rune songs...)
