[Idea by one of my irl friends ^^ btw theres lots of headcanons in this so it def wont be accurate.]
After defeating Subject_1, or Sebastien, you went inside his house in search of why the other outlaws are scared of them. As you wandered down the hall, you were suddenly telaported into a blank white room. And you were met with a white being wearing kiddy clothes, adorned with colorful stickers. They had a halo with two small wings on the side, and another pair of more sharper and sketched like wings on there back. And they also had a mask with a toothless smile, dot eyes, and a smile on it. They then waved at you.
"Oh mi gawd you rilly came buy!" They said in a childish voice before switching to there normal, calm vovie with a hint of insanity.
"Let's put up a fight."
They then unsteahed a white sword with a bow at the hilt. Don't die now!
