i recently played Nioh and realized if there is any games or manga with feudal Japan setting plus demons and magic, Nobunaga is a goddamn villain and demon....why the hell is it i dont understand at all....wasnt he a villain too in Samurai Deeper Kyo? apart from the Mibu clan that is.....
It's a common portrayal due to the circumstances behind the person. The genderbent versions i've seen in two series arent villains.... though they have been seen as 'demons' by some of their enemies.
Some Japanese folks see him from a modern perspective as evil because of his ruthlessness to his enemies.
Brutality was a mark of the time period and all of them did some high-key bad shit at some point or other. Nobunga is a real mixed bag to me. He was ruthless, sometimes brilliant, eccentric and irrational by turns. History is written by the victors which is probably why you're going to see him painted as the villain nine times out of ten. Kind of hypocritical considering his own contemporaries were guilty of much the same with the added bonus of betraying each other and murdering their own kin on the regular.
read it...dint like it.....the anime stopped abruptly too....and ICYMI i said feudal japane with magic and demon settings.... Oda Nobuna was not a demon+magic setting....
Try reading the novel itself, anime is just early into the story. About magic, it exists or rather existed to a point, they have had onmyouji arts but event happend and demon gate was destroyed removing magic from the world.
Several reasons: 1) He was the sponsor for Christianity in Japan, though he himself wasn't a Christian and didn't believe in Christianity. So the Buddhist monks hated him. The Shinto priests couldn't care less. After he passed away, later rulers (not the emperor) attacked Christianity and Christians like what happened at Amakusa and for a time, Christianity was outlawed and demonized. 2) He ruined his own father's funeral rites. There were several theories why he did so, and nobody really knows why. 3) He drove the dude who practically raised him to ritualized suicide. Granted, this happened when he was fairly young and wild, and it was after this event that he started cleaning up his act. 4) He turned tradition upside down with his reforms. Needless to say the traditionalists, even among his own retainers really didn't like this much. 5) He burned Mount Hiei, the most sacred place for Buddhists in Japan and almost snuffed out the eternal fire that had burned non-stop since the 8th century. There are others, but Ai-chan can't remember.
They were all pretty evil by modern standards tbh. Murder was the order of the day and all of the daimyo did it well. Not judging them at all. I don't care and it was normal back then. Nobunga was just more blatant about it so maybe that's why he gets the 'bad' stick when really they were all just as bad as each other.
Out of the all the real feudal Japan era figures I have seen or heard of depicted in Japanese games, light/web novels, anime, and manga, I think Oda Nobunaga might be the most popular or commonly-depicted figure.
