Halo breathing tanjiro

Chapter 1

The Kamado family are well known for creating new breathing styles and having the legendary sun breathing. Tanjuro is the current sun hashira, he is the strongest of the hashira.

"Ill be back from final selection by next Monday, you don't have to worry." His mother, Kie was crying and telling him to be careful. Tanjuro had wished him good luck. Over the years tanjiro has perfected sun breathing and created what he called "Halo breathing". Tanjuro believes it is barely weaker than sun breathing and believes Tanjiro will finally kill Kibutsiji Muzan.

We timeskip to final selection.

Tanjiro is impressed that he was almost inclined to but on his mask because of 7 people there but guessed that they were tsuguko. "Welcome to final selection two girls said, one white haired the other black haired. "Here on Mount Fujikasane there are multiple demons imprisoned  by the demon hunters." 

"You must survive 7 days beyond the wisteria and make it back to become a slayer." "We wish you all good luck" they say as they leave. The participants run into the forest to begin their trial.

20 minutes later

Tanjiro  is running through the forest before encountering his first two demons. They were arguing about who would eat the boy first and decide that the first to kill him would be the one to eat him. They both lunge at tanjiro as he sighs.

He the disappears and reappears above  them. He is facing them as he says "Halo breathing first form: Halo's circle. His sword has little halos surrounding it with the actual sword having a yellow glow encasing it. He cuts through both demons necks and jumps from their backs landing on the ground. 

He continues running before sensing another weak demon, but it's stronger than the 20 he killed already. He jumps into the air a says "Halo breathing 7th form:A calming death." The demon looks up to see tanjiro and he falls into a trance, allowing tanjiro to decapitate him. As the demon deteriorated tanjiro hold his hand making the demon silently sob. "A-aniki."

Tanjiro rushes off again before climbing a large tree. The group of 7 that he had seen before had the same idea he climbs higher and spends the night there. He wakes up and sees that the  group is looking at him. "Who are you and what do you want from us." Says a girl with blue hair. "Nothing, I swear I just wanted to sleep here." "Then get going." Said a Yellow haired boy. 

"Just about to." Said tanjiro he jumps of the tree branch free falling straight down causing the group to panic. "HOLY SHIT,ARE YOU CRAZY." But tanjiro switches his position unsheathing his blade and stabbing it into the tree slowing his fall. He lands on the floor and yells "BYE" They look at him in disbelief and he runs off towards the river he spotted a few miles away.

We now switch to the group of people. Kanao, Zenitsu,Inosuke,Genya, Aoi, Ayumi, and Hana.

"I wonder why he was so nice even though we suspected him from the start." "Just forget it we need to head to that river down there for water and hopefully food. The squad make their way to the river and run into a group of slayers with expensive armor. "This isn't a samurai trial I hope you know that." "So what we come from rich families and we deserve to look flashy." 

Hana sighs and tells the group to walk along and ignore these three idiots. Until she hears the screams of the group that we're behind her. She looked back and saw that the group along with 2 of the idiots were gone. She got into a stance with her hand on her hilt. She backflips out of the way of a bone like material shooting out at her. 

She stared into the direction and yelled "Water breathing 1st form:water surface slash." Water erupts from her sword as she dashes towards her opponent.It is blocked and she sees  that it was a demon. But how? "I know you're probably asking how I'm here right now but look around you girl."
