I know there is already a thread about this particular demon, and I did post there, but I wanted to elaborate on my question:
From what I've read(carefully, as to not Spoil the plot of the game) most sites said that you can fight Lucifer on a New Game+ playthrough, but is that the only way to find him? and if so, are there any requirements that need to be met before being able to fight him?
Lucifer has always been my favorite demon in the SMT series, so I always check to see if he is available when I start a new MegaTen game. Thanks in advance for any info you might provide.
