Note: I made this because I have spare time and my friend told me how he wished "best waifu" is still...active even in just a story like this.
Personally speaking, Inosuke aka Best Boar Boi is my most favorite character.
This is my first story so I would like to hear what you guys think.
We'll kill you both...for sure...
There was once a demon girl that Kochou Shinobu faced. Not only the white haired demon treated the fight as a casual game, she sensed an unearthly power from her. That particular demon is skilled with the sword even if she looks like she's at Kanao's age.
"Before you die...I think I'll be taking you along with the brat. I wonder if a weak Pillar like you will be compatible. I improved this technique for so long and used countless others" A towering demon crystallized his index finger as marks all over his body appeared
The last thing Shinobu remembered with the cornered sword wielding demon is having the pain of a "toxic" substance being infused to her body. The blood of another flow through her, "killing" her first before revitalizing her.
"...?!"
The butterfly pillar awoken, her heart raced fast. Shinobu woke up finding herself lying inside an abandoned home, with centipedes all over the house. Beside her is a butterfly with its wings shredded.
"I remembered dying..yet I'm still here with my body intact"
She inspected her body, the same as she last remembered it. She felt greatly confused to why she managed to survive after fading into the afterlife. It can't be physically possible to how her body is back in one piece.
"Was it a demon's doing? Or was I resurrected by someone...or something?" Shinobu groans in pain
Shinobu's body is still weak but she has enough strength to stand and walk. Her shaking body forced itself outside but standing in broad daylight for minutes caused her to feel dizzy and wobbly so she retreated to the porch. She sat down, exhausted after expanding so much energy from little movements.
"My body is still too weak to move much..."
Her first thought right now is to return to the Demon Slayer corps but she can't do that yet with her body still physically in no condition to travel down the mountains.
"...?!"
When a centipede crawled up to her hand, she immediately flailed it away, uncomfortable at the touch of an insect with a hundred legs and a stinging bite. Shinobu then begun wondering how she is alive again and why she woke up in an old house with what seems to be dried blood on the walls.
"I just remembered...where is my sword?"
Shinobu woke up in her usual attire but her unique katana is nowhere to be found anywhere in the centipede infested house.
There are more things you should be worried about more than your sword...
Reflexively, Shinobu jumped back at the second she heard a child's voice. She wondered if it's a demon voice but it seemed impossible as demons are inactive during the day due to their weakness to sunlight. Without her sword, Shinobu knows she has no chance of defending herself from a demon if it is one.
Kochou Shinobu, do you know why you're still alive and in one piece?
"This voice...? Who are you?"
Even so, Shinobu prepared herself if she's indeed up against a demon who's voice sounded like it originated from inside her mind.
Someone who is stuck with you...
Shinobu's body slammed down the ground like an invisible force pinning her down. No matter how much she tries to push herself upwards, her body refuses to cooperate. An unknown force repeatedly pulls her down, but there's no one in sight except for her.
As long as you continue to exist...so will I...
Shinobu resisted the force pinning her down and stood on her two feet after repeated struggle.
"As long as I continue to exist?"
You won't understand now. Not yet...
The vision of bloodshed overwhelms her current thoughts. Unnamed and unknown humans scream and beg for their live to be spared, but a frenzied demon would never hear their please. The demon roar and scream not in blind rage but in a sorrow that will never fade. Shinobu loses all of her strength in an instant, falling back to the floor with all of her limbs paralyzed and her senses weakened by someone else's power in the deepest corner of her mind.
I'll show what I mean...when night falls...
