I was thinking all of the CEs in general, the Lily one looks like Takeuchi put in some real effort (at least I think it is 社長), shisho+aniki looks pretty good too I guess. As does Ayako if I cared about her. All of the effects on CEs are awkward as heck though.
As for Heroine X...hard to say. So far they looked like they've wanted to keep Assassins as star generators, further separating them into pure generators vs some star gathering skills. Well, the ones with high presence concealment and useful skills (Hassan) are used, and Jack through brute force of an entire kit built around star generation. So with that end filled, this one will probably be some awkward damage based assassin? Unless they tweak individual servant star gather rates hard, the lowish gather rates for Assassins will make it a hassle.
We'll see I guess, even a low presence concealment can be made up with numbers from elsewhere if the motions are there for it.
