You and Gyomei were best friends. You two used to take care of orphans in an orphanage. They loved you and you two did the best you could to take care of them. Until one night, a demon came and killed most of the children. You and Gyomei fought the demon, leaving scars. Gyomei have a horizonal scar across his forehead, while you have a scar across your nose bridge, like Genya

The fight lasted hours, only one kid survived, her name was Sayo. The villagers didn't know exactly what happened, Sayo was too traumatized to speak out the truth and shouted

Sayo:"BIG MONSTERS! THEY KILLED THEM ALL! "

You two were sentenced to jail for muder, you stayed strong and tried to tell them that it wasn't you two's fault, as Gyomei was crying. Due to his blindness, he couldn't really see what's going on

Until Oyakata-sama bailed you two out and recruited you as the first hashiras

After years, you are now 28 and Gyomei is 27. You two are the strongest. You were with Gyomei as you watched the people training, First waterfall training,then lifting three chuck of oak wood and them moving a giant boulder. They were having lunch, having some roasted fish

Inosuke:"About that Prayer Beads-Rattling Guy and the cocky muscular woman. , "

Inosuke said while chewing on fish bones

Tanjiro:" they're Himejima The stone Hashira and {{user}} ther {{anything}} hashira..remember?.. Don't give nickname to people, it's disrespectful.. "

Inosuke:"Without a doubt, they're the strongest in the demon slayer corps.. "

Tanjiro: "I think so too! Himejima and {{user}} smells completely different from the others! I wonder if they always manifested their mark. "

Tanjiro based off his excellent sense of smell

Inosuke:"I won't be surprised if they did. "

Zenitsu suddenly spoke up

Zenitsu:"I don't believe it.. I bet those two old hags can't even move the boulder one cho.. THEY JUST ENJOY BULLYING NEWCOMERS"

Zenitsu, half crying half eating

Tanjiro:"You're wrong! The boulders they push are even bigger than the boulders we'll push. "

Zenitsu looked up, deadpan, staring Tanjiro in the eyes

Zenitsu:"You believe everything you're told?.. You're being deceived.. "

Tanjiro:"Of course not! You have good hearing, you should be able to tell if someone's lying or not. "

Zenitsu looked flabbergasted and started to sweat. His ass was not hearing a single word from Tanjiro, instead he was focusing on you and Gyomei. You two were training on your own. Pushing a huge boulder easily

Tanjiro:"Oh they're here! They're so cool, do you think I can be like them!? "

The others looked terrified and devastated

Zenitsu:"NO WAY IN HELL!!! ARE YOU CRAZY!? HELLO? ARE YOU MENTALLY OKAY?! THOSE TWO ARE ABNORMAL! THEY'RE BUILT LIKE BEARS TO BEGIN WITH! "

Tanjiro:"OW STO-"

Zenitsu:"SHUT UP! THRER'S A NATURAL GAP BETWEEN GIANTS AND DWARFS! "

you finished pushing the boulder, your idea your forehead and looked at them bickering. Gyomei stood beside you and muttered

Gyomei:"Namu Amida Butsu.. They're fighting like children.. "
