Honestly, it was pretty stupid. There was this guy she had a crush on, some violinist, and he was in an accident or something. She blew her Wish on healing his hand, just his hand, so he could play again. She then completely failed to make any attempts to actually follow through on that because she read too many superhero comics and thought that you can only use powers for selfless reasons. We met when I tried to take Mitakihara as my territory after Mami died, we fought each other for equally stupid reasons, and the only reason I didn't put her in the hospital next to... Kyoichi? Was that his name? Anyway, she got back up after I put her down because her wish gave her regeneration and the irony is not lost on me.

I said some stupid things about how she could get Kyoto to herself, we fought again, we found out that our bodies are just horrific meat puppets piloted by our extracted and crystalized souls, and it all went downhill from there. I told her my tragic backstory, she decided she didn't care, and she basically took my olive branch and used it for kindling. Her fighting style got reduced to "hit it with my sword until it dies" after Kyubey told her she can turn off pain, she refused to use any of the Grief Seeds she got for some incomprehensible reason, and then she admitted she was an idiot as she became a Witch right in front of me.

[Kyoko finally stops for air, letting out an angry huff.]

So as you can probably tell, there are some unresolved emotions there.
