How will this work?
The shogun can be only one person. Who would respect a shogun that depends on another strong man? Or Nobunaga kills him or after Nobunaga's death he will be appointed his substitute and rightful successors of the Ashikaga Shogunate. I imagine if Shizuko will notice that Akechi Mitsuhide will still betray Nobunaga but let happen to kill Nobunaga and preserve her Uncle, at the same time using her influence to make him take control. He may even marry Nouhime to make his case stronger.
EDIT: also, Shizuko could protect the Jesuits to exploit he pacifist message of Christianity in the post-war world?
EDIT2: oh, yes, this would also means that Shizuko would have to defeat threat to him, like Toyotomi and Ieyasu...
@Charkan
<Aku> LONG AGO, A FOOOOOOLISH SAMURAI INTEREFERED IN MY HISTORICAL SAMURAI DRAMA! SO I THREW HIM INTO THE FUTURE THAT IS PER AKU'S SAMURAI FANFICTION! NOW, HE HAS RETURNED TO THE PAST, TO...oh, I guess he didn't make it back all the way. HAH HAH, I WIN AGAIN!
@Kirin-kun because she know who he is, someone who is supposedly to be dead.
Aw man, the timeline is fucked up....
Luís Fróis receive permission to work at Kyo from this man, Ashikaga Yoshiteru. Ashikaga Yoshiteru death is one of the reason Luís Fróis seek Oda Nobunaga...
@Panino Isn't Nobunaga already installed his brother, Ashikaga Yoshiaki, as a puppet shogun at this point of time?
yeah, this timeline is now fucked up... trying to preserve the timeline is moot at this point.
