And it's finally here, the Oda is no slouch so is his wife it seems they already have Shizuku nature more or less figured out the only reason he didn't press Shizuku for more aggressive technologies is that what she has given him already has helped him a lot, but now a second one appears depending on how things go he may use more extreme methods.
I don't fear he will anything to Shizuku, in a way she being a girl makes handling her easier in their mind and i think he likes her in his own way, but Ashimitsu is in the ropes now, Nouhimes seems to be the only one that knows about him for the time being but how things will develop may change things a lot.
And at this point, i am completely convinced they already created another timeline.
