Controversial: Kusari never had an Emperor

[Zelot]

Actually, I called the Emperor Kogen as an homage to Japanese history itself. Kogen is considered to be the "Legendary Emperor" because there is no verifiable facts about his rule or if he actually ever existed. Jien was a Japanese poet who wrote about Kogen.

If you were curious about the name. Just one more homage to historic Japan.
