Just... come on... It's my second favorite boss from FF... I have to say I love it. Sorry for the late replies, Xmas season has been CRAZY.
Here is a song that has a lot of emotion to me, and I know many who have played Persona 4. This is a great alternate version of it.
If you haven't played, are looking to play, or are currently playing Persona 4(or Golden), Do not look up about this song... Just warning, That's spoiler territory.
