Well, on the ... bright side? ...
Uh, the good news for her ...
Erhm. What I'm trying to say is, it's pretty likely she'll get her wish in Gensokyo. After all, yokai aren't exactly known for their pacifism or consideration of others. Why, just of the top of my head, there's a vampire noble, an immortal princess, and a gluttonous ghost who'd fit her desires and they even come complete with other love interests to favor over her! If she's willing to accept a more self sufficient or less entangled partner, there's also a "nice" flower yokai and an Oni she might approach. Most of those should be at least somewhat survivable, depending on how durable and/or cute she is.
That said, I've fallen out of the loop with Touhou, so who is this girl?
