This just came to me out of nowhere: with so many different timelines, there has to be one where the two Black Hats love each other and have a kid, right?
The kid's appearance can be based on Vanitas. Seeing what Vanitas looks like was what inspired me to write this. He really has that look where, at first glance, you think that's exactly what a child of the two Black Hats would look like.
The kid's appearance combines features of the two Black Hats, and even his name is a mash-up of theirs.
The author's writing is awful, the style is goofy, the logic is dead, and the characters are wildly out of character. The main goal is just to have fun.
