Summary
It was hot. That’s the only thing hitting Mizuki right now, sweat stinging her eyes as her chest heaved. Zenitsu wasn’t far behind, panting even louder than she was.
A loud, stern voice ripped her from her thoughts. “Chin up! Pay attention, you two. Do you want to die? Demons will not care for your daydreams.” Gramps swung his cane sharply under their feet. Both of them yelped as they toppled forward, landing in a heap on the dirt.

Summary
Death followed Ichigo with a near obsessive persistence. Though, she was partially at fault for about six years of her life. She chose to become a demon slayer after all. But, death still persisted to be her curse.
Her mother died and she lost her father to grief. She met Nēsan and found love in her and her family... until her parents were killed by demons right in front of them. They were saved by Himejima-san before they could be killed and their paths were set in stone. They became demon slayers, Ichigo taking a new name and becoming Kochō Shinobu to protect her own family.
Things looked better, until Kanae is killed by that fucking demon. Ichigo swears revenge and takes on the duties of the Head of the Butterfly Estate as well as Insect Hashira. Every one of her Tsuguko except for Kanao had been killed, the families of her girls, and every demon slayer she failed to save from their injuries.
She was furious. And then the battle against Kibutsuji Muzan and his Demon Moons. She was determined to kill the bastard who killed Nēsan. Even if she killed herself in the process. Yet, she survives the impossible and now, everything is over. They won.
Unfortunately, her job isn't done just yet.

Summary
When one lost soul encounters the easily frightened boy. The world around her is filled in black and white; her view in life is the horrors of bloodshed past.
Emotions, a foreign reaction stirs within her when that boy, his hair resembling the vibrant sunset of the morning light covers her palm with his large ones.
Truly a rarity if one demon and a human found comfort in one another through time they teach each other a lesson.
And that is the beauty of accepting each other’s difference.

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
Zenitsu knows that he is cowardly, pathetic and not needed by anyone. He doesn't want to train just for the sake of being killed by a demon one day, but he's too weak to object or even escape without being caught and brought back. He cries, cries, cries and can't stop. But one day lightning strikes him and vague pictures appear in his head. He can't even explain what's going on, but after meeting friends, he picks up a sword and prepares to fight.
After all, Heaven, even if it doesn't know about it, is a very selfish and protective attribute. And they will never give up to anyone what they once recognized as their own.
