Damn, I am remember some poem about 3 great shogun
If the cuckoo does not sing, kill it (Nobunaga)
If the cuckoo does not sing, try to make it sing (Hideyoshi)
If the cuckoo does not sing, I will wait until it does (Ieyasu)
@Leo80221: Unsure if it's a fact or not but it's said Nobunaga once referred to himself (likely jokingly) as the 'Demon King of the Sixth Heaven' (It seems to be like a Buddhist equivalent of Satan).
It gets brought up in most manga series with him as a character. That's probably why Reimos called him chuuni.
I remember something about Nobunaga being okay with being called a demon lord, when he burned down the mountain occupied by opposing warrior monks. I read it from Nobunaga no Chef.
In buddhist teachings, the Demon King of the Sixth Heaven is someone who leads people away from buddhist teachings. Since Takeda Shingen, one of Nobunaga's biggest rivals, named himself protector of buddhism in Japan, Nobunaga named himself as the Demon King of the Sixth Heaven (i guess because he beat the shit out of a lot of buddhists during different campaings LOL)
