Dang this turned out good. IMO my best Touhou rearrange yet, better than Complete Darkness. Somehow, I feel like I was able to keep the ZUN vibe strong despite it being a completely different genre. It sounds like it would be a remix of a Seihou song. Especially that synth duet part. Although I wrote that bit (and all the melodies except the first "last judgement" one), I think I subconsciously took little pieces from a bunch of different touhou songs (especially TH retro + seihou) and made a salad.

Original - The Last Judgement
