Thank you Kermitt from my previous videos comments for telling me about this!!
It was the only one that I didn't get. ^^;

Took a while, considering I had to reset a couple of times to get the hidden trophy. Was worth it getting 100% for all the trophies. (It doesn't matter if you do this in the Aloe or Fubuki versions.)
Now I can rest from HoloFunk... for now.

Go check out KeatonHishida for making this custom mod! https://www.youtube.com/channel/UCA3oHB9MgVrg8ZDwAYseSKw
