Jack the ripper

AQQ. Jack generates her NP on most of her brave chains because she's normally critting so much that it bypasses her relatively average NP gain.

Her quick crits alone generate pretty good NP, but crits in general give her np charge pretty effortlessly.

AQQ generates a pretty good amount, particularly if you have a CE giving quick card effectiveness. She has a good hit count on her quick cards and not terrible charge gain. Once you get a decent number of crit stars (or good supporting servants) she can potentially NP brave chain and then NP again next turn.

I lack an Imaginary Around due to inability to roll one, so depending on my mood I cycle through Hot Spring Under the Moon, The Classic Three Great Heroes, and more recently Holy Night Supper.

AQQ, with quick up CEs.

Or NPQQ Brave Chain with her first skill activated, for both optimal damage, lots, of stars, and a NP loop =P

That's interesting, Jack's NP gain is pretty famously really good. The best way is AQQ+extra, and usually you'd want to make use of the crit stars she generates for this too.

How do you normally generate??
A question like that never even came to my mind. 😂
Honestly though, Jacks NP-Gain is insane. Whether you use QQQ+ or AQQ+ her NP-bar literally jumps. That, combined with her sh*tload of C-stars she generates each time, I can practically spam her NP like with no other Servant.
I'm really glad she was my very first SSR.

Jack's NP gain is hands down the best in the entire game XD
