Thanks! I'll keep trying. I'll update if things change!

I'm sorry for the late reply, I've been busy lately.
I have absolutely no idea how to/if you can reply to comments as it's not showing up. However, to answer the question.

I'm pretty sure like most of the events/side characters in monster prom her showing up is random.
there are a few endings, all centred around a few choices made if you find her and Vera in a library event, but i am working on some item events to add in when they're written out properly.

I don't think it is a glitch, at least I certainly hope it isn't.
Though I'm glad you like my character and I hope to add more content eventually!

Loved the mod! Tygah was so adorable. I couldn't get an ending though, and when I tried playing again with the mod loaded, she never reappeared. Is this a glitch?
