When City of Flowers plays, you can hardly take the mission seriously. Often involves Okuni and something foolish, like a "tournament" to decide who is the most beautiful woman or extortion of strong warriors to gain some money for her shrine.
Anytime Ranmaru is confused with a girl. Including the example of tournament for beauty.
Some of Okuni's quotes to certain characters. And also exchange of dialogue between Okuni and various characters.
Nene's Dream, Melee at Sekigahara. She goes out to spank EVERY SINGLE OFFICER in the Battle of Sekigahara, and is likely the ONLY Dream Stage with an ending, that shows her lecturing officers that are now grounded. Bad children deserves punishment, and mommy Nene won't go easy on them. Even Ieyasu admitted, after Nene defeated him, that "he's never been scolded like this in his entire life".
Gameplay and Story Segregation: In Mitsunari's SW2's story mode, he already has rivalry with Kiyomasa and Masanori (both are still generic NPC) who greatly disliked him. However, every time you (as Mitsunari) defeat an enemy officer, they still praise you (Mitsunari) with generic quotes. This is strangely funny, despite justified with the fact those two are still generics.
Generic!Masanori: "It seems you've got a bit of devil in you!"
Generic!Kiyomasa: "An exemplary warrior!"
There is one scene in SW 2: Empires, in which Nagamasa Azai mistook Kotaro Fuma, of all people, as "a dead woman's ghost".
