. . . *shudders* I... don't even know how to respond to that.... you know, I am surprisingly okay with that reality.
Not because I want Jacob to explore different venues of villainy, but because it could be more like another little sister, or something else entirely [platonic] (like a fanatically loyal minion with a cold interior with just a bit of warmth for her lord).
... Yes, it's not a waifu then, but dammit it's not the wording, but cute girls that matter here.
Part of the 'want' was the look of surprise, and shock on/in both Vivian's and Jacob's faces/reactions that segues into argument, and then agreement that they both stop and try to figure out what just happened. But Vivian still becomes an Ebon Magical Girl either way. That'd require it to be a surprise for/to Jacob.We do have write-ins to make your dreams come true.
[] Vivian. A middle-schooler and your little tsundere sister.
