Ben and mitsuri made their way towards her house.It had turned night time and Ben had his guard up as he knew this was the time that Demon's liked the most.But then Ben was shocked alongside a scared mitsuri with what they saw in front of them.
The doors of the house was broken,with footprints that were bigger than a human's and had claws on them present on the ground.'Shit!Is this the butterfly effect?Due to my intervention when mitsuri was about to meet Ubuyashiku,the world is somehow trying to fix this to make sure she becomes a Demon slayer!?'Ben followed mitsuri who ran inside the house.When he walked inside, he saw a sight that made his stomach sick as he would have puked if not for the danger infront of him.
Mitsuri was on her knees crying as she looked at the situation infront of her.Ben stood infront of her as he glared at the thing before him. It was a demon,it had a human head with yellow eyes,it had a bear like body with claws as well. The most horrific thing was the human heads it was holding in his hand while he had a small hand that looked like it belongs to a child in his mouth.The human heads were Mitsuri's parents from Ben's memories.This bastard killed them and Mitsuri's small brother's!
"Well,well,well.I didn't expect to see more meal coming towards me.Today is really a feast for me.This is great.The children didn't quench my hunger as much as the adults do~"The demon said as it threw the heads down and looked at Ben and mitsuri."You bastard!"Ben snarled angrily as he took out his sword while keeping his guard up incase the demon went after mitsuri who was having a mental breakdown at her family's loss.
"A demon slayer!"The demon said in surprise While looking at Ben,but Ben zoned out what he said as his mind became clearer when he held his sword.His face showed no emotion as he looked at the demon coldly.The demon felt a chill run down his spine when Ben muttered his breathing technique."Sun breathing, first form,dance!"Bright Red flames appeared around Ben's blade as he dashed at the demon at high speeds and stabbed him in the stomach while blasting him out of the house.
Mitsuri was shaken out of her thoughts as she looked outside and saw Ben throw the demon away from his blade as it exploded with red fire.He screamed in pain as he was burned away by the flames.Ben looked at the dieing demon, before he walked towards Mitsuri and took her in a hug.Mitsuri shook in his hug as the dam broke.She cried hard against Ben who patted her back to console her as he didn't know what to do.
Ben looked to his side and saw a crow sitting on a tree.A man appeared from the forest. His eyes were pure white while there were purple patches around them.He was Ubuyashiku,the leader of the Demon slayer corps.Behind him stood a black haired man with blue eyes while wearing a red and green coloured haori.He was Giyu Tomioka,the water hashira.Giyu gave mitsuri and Ben a glance before he looked away as he silently stood besides Ubuyashiku.
"My condolences for your lose,Mitsuri-san." Ubuyashiku started as he looked at the crying girl who didn't seem to hear him."Ano,can you wait for a while.She is not in the right state of mind right now."Ben said as he looked at mitsuri."That's okay with me.I would have suggested the same.And might I ask who you are?"Ubuyashiku gave a sad smile as he looked at Ben.Ben didn't know how this guy was looking at him in the eyes.He still answered him."I am Benjiro, Mitsuri's.....fiance. I am training to be a Demon slayer."
Ubuyashiku nodded at Ben while saying. "When mitsuri-san is calmed down and the burial is done.Please follow this crow.He will lead you to your destination."He said it like he knew mitsuri and Ben were gonna come to his place.He again gave a sad smile towards Mitsuri as he went away with Giyu following him.
'What the hell is happening right now.Why in the world did Mitsuri's parents had to die?If this was a butterfly effect caused by me,then I will have to take responsibility.'Ben thought as he looked at the still crying Mitsuri and patted her head while hugging her tightly.
------------------------Time skip-----------------------
It has been three days since that incident.The kanroji family,or what was left of them,were given a proper cremation by mitsuri and Ben. Mitsuri was still sad about this incident,the iconic smile and love she showed to Ben gone.Ben was sitting on a chair while running his hands through a sleeping mitsuri who sat on his lap.He had just managed to make her fall asleep as she had been staying awake for the past three days.The crow left by Ubuyashiku was sitting on a tree outside the house.
'I feel so terrible right now.I completely forgot about how me meeting mitsuri will cause the butterfly effect to take place.I would have caused the butterfly effect sooner when I joined the Demon slayer corps in the future, but due to my involvement with mitsuri,she had to suffer by it.'Ben had small tears in his eyes as he was beating himself up for causing this much pain to mitsuri.He was the cause of her loosing her smile.
He wiped his tears as he looked at the sleeping mitsuri.'No more.I will not let mitsuri be sad like this!This was caused by me,So I will take full responsibility!'Ben swore to himself as he had made his decision to protect mitsuri and make sure to return her smile!
