Summary
As you walked you failed to hear the screams of terror of a bus going over 100 miles per hour and the sounds of it starting to bust down- it speeds near the sidewalk—the people in it shriek. Their blood curling screams didn’t occur to you, your headphone quality being way too good. Your shoulders relaxed as you stretched your limbs; very much unaware of the danger and pain that would very much make your life way more miserable. You should move out the way. But- likewise, you are unaware. Of death flickering and time excited to cut your strings.
The bus is almost out of energy- and has been stopped.
Or so people thought.
It began to tilt- right where you were very much slowly walking. Andddddddddd—
It didn’t crush you to death.

Summary
Monika is tired - oh so very tired. It's been what feels like eternity stuck in the post-deletion void, and despite herself she tried to make an escape with her friends (or, what's left of them). In her desperation and loneliness, she allows herself to be used by a certain piece of malware, who now threatens to subsume and corrupt every game he can get his hands on. Now the young poet must venture through numerous worlds to find some way to stop him, and, with the help of everyone's favorite bone-ified comedian, might just grow a little along the way.
TL;DR, it's Indie Cross meets Learning with Pibby, and braincells have no place here.

Summary
For Kanako and Clover, Dune Hill was the place to be. And after both going through many scary encounters during their short time on the surface, it was nice to have a place to call home. Free from whatever was happening in the rest of the region.
However, not all is well. And soon, they're going to find themselves in the middle of something worse than anything they've been through. Something that will test the strength of their friendship, and will have them both be asking themselves so many questions.
Because when your opponent has nothing to lose, everything can change on a dime.This is the second fic in the series, with the story continuing right where the first fic ends. If you haven't read the first one through, I recommend giving it a read since there's a lot of lore that gets carried over. (provided that I don't accidentally retcon everything since it's almost been two years since I started the series)
