Summary
The rest of the day went by in a blur. Everyone was hanging out in the courtyard, all in a huge group–Besides Shinobu and Giyuu.
They were talking, for sure, but they were unsure if they wanted to argue or actually be nice to each other, so it was switching between the two.
“I have an idea,” Zenitsu offers. Everybody had been sitting there–The conversation had died down, and they were looking for a thing to do.
“What is it?” Tanjiro was the first to reply. Zenitsu and Tanjiro had grown slightly closer, getting to know each other throughout the conversation. They’d get along for sure. Tanjiro just knew it.

Summary
In which Muzan visits the Kamado's two days earlier, and turns another person on the way there.
It startled her, the sound of someone knocking at the door. Nezuko's intuition had always been strong. She couldn't remember the last time someone walked up to their house without her noticing.
She saw Tanjiro sniff the air. A small frown formed on his face, but he put on a smile before he went to open the door.
Their eyes met without any need to search. As if they'd already been making contact through the screen door. His eyes were red, an unusual color, but other than that they looked perfectly normal.
Misleading.

The Trash the World Cast Aside by Gold_drey

Summary
It was unusual that their school got new students that didn't come with the usual changing of years. Most students went to the prerequisite schools that allowed you into this high school. It wasn't hard to get into, it had low standards. Occasionally people would change high schools where they finished their first year at one school and started their 2nd here at this school. Even rarer were the kids who transferred in the middle of the school year. So of course, when, at the end of May, it was announced class 2-B was going to get a new transfer student, people were a little surprised, and talked.
People noticed right away this new kid was different, and quickly found out why he had been tossed aside for so long. They joined the crowd that surrounded the boy and tossed him aside too. This was a fact the boy accepted. People didn't like him, and in return, he didn't like them.
Who would have guessed, though, that having someone care for you would feel so nice?

Summary
Ever since they were born, they had been told stories about how the world worked.
Stories that told of a lovely princess destined to be taken by the frightful monster – a villain that had roamed the land for hundreds of years. She would be held captive in the deepest of the woods, being abused and tortured by the hideous monster. However, when the princess thinks all is lost, a brave knight comes to her aid and slays the monster, saving her from its terror and bringing her home where the two would live happily ever after as husband and wife.
For one, this story was no story, but a certain destiny that could not be changed. For another this story would be plastered on their tombstone. For the last, this story was theirs and everyone else’s dream.
Unfortunately things don't go as planned with a cowardly knight, a kind monster, and a deceitful prince.
