I'm missing the last 3 endings and I can't figure out how to get them. Could you PLEASE give me some hints? If you give me your Tumblr I could message you there to avoid putting spoilers in the comments.
Sure - my tumblr is http://konoi-and-noir.tumblr.com/
You can either message me, or wait a day or two until a make the guide - I'll post it there anyway!
