Summary
In a different timeline, Makomo became the water Hashira, this won't make Giyuu or Sabito return to life, but at least she can honor their memories. In another timeline Sabito spared the demon girl after witnessing the bravery of her older brother, he sees a little of his younger self in him, at least he hopes the boy can protect his sister, unlike him, who couldn't save Giyuu during the final selection. Giyuu doesn't know what is happening; one moment he's slicing Lower Five's neck, another moment he faces two slayers who hold an uncanny resemblance to his late friends.

Summary
He was nine when his sister died. He was nine when he murdered a demon in blind rage and terror. He was nine when the villagers thought he was crazy. He was nine when he ran away and found shelter in the forest.
No one ever found him. No one showed him the path of the demon slayer. He himself discovered this path and followed it. He was not a member of the Demon Slayer Corps, yet he killed many bloodthirsty monsters. No one knew this person who, in the shadow of darkness itself, killed those demons that the Corps did not know about. All they knew was that he didn't belong to any world. Neither the human world nor the demon world.
He followed his own path, not walked by anyone else. He was different, but that was better for him than forcing himself to fit in with people. He liked being different from others.
His name is Tomioka Giyuu, and he is a wild slayer who doesn't take orders from anyone.

Summary
Omegas were well known for their patient, caring nature. They were sensitive souls— but that’s not to say they were weak. No, omegas were terrifying, especially when their pups were in danger.
Shinazugawa’s blade dug through the box, stabbing into the demon, and the high-pitched wail that rang through the garden was unbearable.
A pup was crying. Two pups were crying: Tanjiro and whatever was in that box.
When a pup cried like this, usually their parents came running, no matter how far away they were. It was a cry for help, only used when in severe distress or danger.
And for a second, nothing happened.
Then all hell broke loose.
Shinazugawa was sent flying, everyone else had fallen over in the process of whoever-it-was that’d rushed over. The box that contained the demon was placed down in front of that Kamado kid. The boy wrapped himself around it, protecting it with his own body as he sobbed.
As their daze cleared, they all realized that it had been Tomioka to rush to the kid’s aid, reeking of distressed, enraged omega.
But that didn’t make sense. Tomioka was a beta. Right?
To say that they were confused was an understatement.
