(Author POV)
When Tokan had arrived at Nagatumo Mountain, it was already dark, and she was running around trying to find the demons. There were demon slayer corpses everywhere, some died without an injury, some died with injuries, and there were strings attached to them. Spider demon? While she was looking around when she heard a scream in the air, wait the air? She thought and heard,
"Don't die! Don't die Inosuke! Survive! Live!," Tanjiro screamed as he was flying through the air.
'What was that?' Tokan thought.
She then spotted the boar boy hacking the demon's arms screaming, "If you can't cut it with 1 sword, use 2 swords! HAHA!"
When the boar boy cut off his arm, the demon started running away, running towards Tokan.
"Running away?! GET BACK HERE!" yelled the boar boy chasing after the demon.
'The demon seems to be coming towards me, well I guess I'll kill it', thought Tokan.
[Frost Breathing, Second Form! Rapid Glaciers!]
as Tokan launched herself forward cutting the demon's arms, legs, and neck off.
In the boar boy's vision, a figure suddenly appeared and said,
[Frost Breathing, Second Form! Rapid Glaciers!]
cutting off the demon's arms, legs, and neck off in a swift motion.
He stood there amazed at how you easily killed the demon,
"Hey you! You're incredible! That was one of the Twelve Kizuki! Fight me! Once I defeat you, I'll be the most powerful!" The boar boy said.
"Hey! Did you hea-" Tokan turned around and stared at the boar boy, the boar boy's instincts screamed, 'Danger! Run away! Fear!' when he looked at your cold eyes.
"That was not one of the Twelve Kizuki, a demon as weak as that would never be one. You must be the boar boy or Inosuke, I'm Furoku Tokan, call me as what you see fits. Now rest, you're injured." Tokan told the boar boy.
Before Inosuke could react, he was already tied by ropes and hung from a tree. 'Fast, way too fast! Incredible!'
"You're strong Furoku! Untie me and fight me!"
(Tokan POV)
What a weird boy.
Tanjiro seems to be having trouble, a fire breathing form with blood demon arts? I thought he used Water Breathing, it must be that mark and the blood demon arts is his sister. I looked up and saw that she was tied in the air, she seems to be fine for now.
It may look like Tanjiro cut off the demon's head but there is a still a string attached. Oh he must've,
"Cutting off your own head?" I said.
"Tokan-san? What're you doing here? Tanjiro asked.
"It seems we meet again, I'm here to help you by orders. You should worry about yourself and sister. That demon cut off his own head." I said.
"Really? Will you be alright? He's one of the Twelve Kizuki, Lower Demon 5." he said getting his sister down.
"I'll be fine, a demon as weak as him won't hurt me." I said
(Author POV)
"It seems you have a good eyesight but you're too weak!" The demon said,
[Blood Demon Arts! Cutting Head Rotation!]
Strings with blood with a circular point in the middle started coming towards Tokan as she,
[Frost Breathing, Tenth Form! Frozen Love!]
as Tokan launches herself forward faster than the demon could see, cutting through the threads and the neck of the demon. She was able do this by seeing the aura of the opening.
(A/N: Similar to Tanjiro's Thread but she can see an aura.)
When she was heading towards Mt. Nagatumo, she trained her eyes. Tokan would focus her perception on something until it was out of her sight, thus she was able to see an aura of something.
(Tokan POV)
"It seems I wasn't needed. I'm Tomioka Giyu, call me Giyu. And you're that boy with the demon sister." said Giyu.
"I'm Tanjiro Kamado." said Tanjiro.
"I'm Furo-", before I could finish my introduction, my instincts screamed danger. I turned around and saw a familiar aura, Shinobu-san?
[Frost Breathing, Twelfth Form! Insight of Snow!],
seeing 3 seconds into the future, I saw the blade with an aura of Wisteria Leaves headed towards Nezuko. Poison?
When the blade came, I deflected it while Giyu stood before Tanjiro protecting him.
"Ara?~Why did you get in my way Tomioka-san? Despite saying humans and demons can't get along, you protected one. This is why no one likes you." Shinobu said.
"I'm not disliked by people." Giyu said.
"..." said Tanjiro.
"...perhaps you didn't realize it?" said Shinobu.
"Giyu..." I said.
"Ara~You're here too Tokan-san, I see. You were the one that deflected my strike, I didn't even notice. My strike was targeted to the demon, why did you block it?" asked Shinobu.
"Well..." I said, when did we meet?
"She's a demon but uh...she's my little sister." Tanjiro said.
"Poor soul, how about I use gentle toxin so she won't suffer?" Shinobu said.
"Tanjiro, run away. Even if you can't move, move." said Giyu.
"Tomioka-san..." said Tanjiro before running away.
"I guess I'll follow Tanjiro, there seems to be another one." I said chasing after Tanjiro.
After a short while, I felt my instincts tingle a bit, an attack from above? Not towards me but Tanjiro.
Then, Kanao, the girl I had taught for a bit, came down and dropkicked Tanjiro's head leaving him unconscious. Before she was able to chase after Nezuko,
I intercepted,
"It's been a while Kanao, unfortunately I can't let you chase after her." I said.
"Tokan-senpai, why are you protecting the demon?" she asked after flipping a coin.
"Well beca-" again I couldn't finish. How many times has it been? As the crow said,
"Message! Message! I have a message from headquarters! Tanjiro and Nezuko are to be taken into custody and be taken to headquarters! And Furoku Tokan is to be headed to headquarters immediately!"
"What a surprise, I must take my leave now." I said without a hint of surprised. Kanao had an aura of confusion before going back to a distorted aura.
I headed towards headquarters and arrived quicker than anyone else.
When I arrived, there seems to be a line of demon slayers which I assume were the Hashiras since I saw Mitsuri among them.
"Ubayashiki-sama, I've arrived. What did you need?" I asked as I kneeled.
"Tokan-san, you arrived rather quick, I was going to introduce you to them but seeing as the others have not arrived, it will have to wait. For the time being, why don't you come up here and sit." said Ubayashiki-sama.
"Yes, but if I may ask, can I rest for a bit? My eyes still need to get used to seeing so many auras." I asked.
"Of course, we still have time." said Ubayashiki-sama.
"Thank you." I said before closing my eyes.
The hashiras were mad and shocked as Ubayashiki-sama seemed to respected you despite showing no signs of gratitude.
I woke up to the sound of,
