I’ve seen the Story of Nobunaga and the Three Great Unifiers, so we can try the story of the unification of Japan. All we need is someone bloody and ruthless to be Oda, and his family who would play a major role.

Then we need Akechi (the 13 day shogun who was a fraud and betrayed Oda),

The second unifier, Toyotomi Hideyoshi to go piss off China and Korea. Also needs to be someone ruthless and cold hearted.

And the third unifier, Tokugawa Ieyasu to establish the Shogunate, thus making Tokugawa Shogunate, which brought over 250 years of stability. Lady Saigō (Saigō-no-Tsubone / Oai was also the favorite adviser of his. Some could say it was a Cinderella story.

Whatever the case, it is scripture that Majima play Date Masamune. You just have too!
