Bah, I'm gonna go ahead and say it, since only a small part of my audience has ever played SMT

(SPOILER)Lou is Lucifer. He is an important character throughout the series who is far less unambiguously evil than you'd think. Of course, his characterization largely depends on what alignment you choose, but most of the time he's characterized as someone rebelling against the status quo who wishes to free humanity from its chains. He's the epitome of the Chaos alignment, so if you're Law-aligned, he won't be very friendly to you.

So far he's shown up as!

Louis Cyphre (the vast majority of times this is his pseudonym though he's looked different)










Most recently, he's taken a female guise, including Louisa Ferre



And Hikaru!





Honestly, making him a hipster/street artist felt like it fit the setting and the character's general theme. We'll see how well I can implement it in the story itself though >.>
