No one's POV

"So Tengen-san is retired and now we have a mission with the ice Hashira" Zenitsu said "I never heard of the ice Hashira before, I thought it was only the Flame, Love, Water, Sound, Wind, Serpent, Stone, Insect and Mist" Inosuke said "I think he is a new one" Tanjiro said. The three trio saw a male cleaning their sword in the garden next to a pond and sitting on a rock "I think that's him his scent is different from the other Hashira's" Tanjiro said "I think he is a demon" Zenitsu said "his scent is also like a demon, how did a demon get here? It's also not sunny" Tanjiro asked. "LETS KILL 'EM" Inosuke yelled as he ran towards the cloaked male but then dodged Inosuke's attack by using his own sword to knock out Inosuke's swords out of his hands and continued cleaning his sword "this demon is strong he didn't even lift up his head" Tanjiro said as Inosuke also tried to attack him after grabbing his swords and the others also attacked the hooded male. "Stop already, this is pathetic" the person said as he took off his hood and it was a half and half male with heterochromia eyes and a large burn mark "what the" Zenitsu said "wait guys his scent is now human, but how?" Tanjiro asked as the two stopped attacking "right let me introduce myself, my name is Shoto Todoroki and I am the ice Hashira" Shoto said as he got off the rock and looked at the surprised trio. "Wait you where just a demon but how are you a human now?" Inosuke asked "I'm half-human half-demon which means I can turn into a human or demon any time I want and since I am a human now and the sun is coming out I won't be able to die" Shoto said as he put away his sword "oh sorry about attacking you we didn't know you were a Hashira" Tanjiro said "eh, I'm used to it by now Sanemi and Obanai does it 3 times a week" Shoto said. "So, how long have you've been a pillar for?" Zenitsu asked "6 years" Shoto responded making the Kamaboko squad freak out "HOW DID WE NOT SEE YOU AFTER THAT MISSION WITH THE SPIDER DEMONS?!" Inosuke yelled "I was called in a mission last minute by Oyakata-sama assisting demon slayers who lost many of their comrades to another demon family" Shoto explained "so we are going to learn from you?" Zenitsu said "yes, I am going to teach you guys but it sounds weird saying we are almost the same age" Shoto said "wait we are 15" Tanjiro said "I'm 16" Shoto said surprising the trio "wait a minute we're going to be late for the mission" Tanjiro said realizing "no worries" Shoto said as he grabbed Tanjiro, Inosuke, and Zenitsu and they went to the bottom of the mountain "we can continue here try to keep up" Shoto said as he started to run and the trio ran after him. 

Some demons tried to attack Shoto but he ended up killing them in anger instead as he was covered in blood and Zenitsu started to scream and cry, Inosuke wanted to challenge Shoto, Tanjiro looked happy that Shoto is the Hashira they are training under. "Wow, you are so cool Todoroki-san!" Tanjiro said "uh, thank you Tanjiro" Shoto said and then Nezuko came out of her box "is that your demon kid sister?" Shoto asked "NEZUKO-CHAN!" Zenitsu yelled and then Nezuko had her eyes whenever she sees a demon. Nezuko started to try to attack Shoto "NEZUKO! NO!" Tanjiro yelled then Nezuko stopped and then tried to protect the trio and Shoto just blocked all of Nezuko's attacks without even attacking her "oi, Gonpachiro Kamaboko's little sister, he is a Hashira and is training us so stop attacking him" Inosuke said. Nezuko still had her eyes slit then moved cautiously towards Shoto then her eyes turned back to normal and she patted his head which made Shoto flinch but then allowed her to pat his head "hey I was wondering why did you flinch when my sister patted your head I smelled a hint of fear" Tanjiro asked "I'm not used to people touching me due to my childhood so I always have my guard up no matter what" Shoto admitted then Nezuko hugged him which made Shoto surprised. "Can someone tell me what she is doing" Shoto asked "she's giving you love and affection" Tanjiro said as Zenitsu was jealous Shoto started to cry and fell to the ground "I never knew what love meant or how it felt so thanks Nezuko" Shoto said as he hugged back "you have a scent of sadness and truth" Tanjiro said as he came to the two then slowly everyone had a group hug. 

After everyone had a hug Shoto felt better and then they continued the mission until the sun started to rise "WAIT NEZUKO GET IN THE BOX" Tanjiro yelled and she was panicking to shrink "wait, lets get to the shade for a moment" Shoto said and everyone went behind a tree and Shoto got a bottle of liquid and it had a picture of the sun on it then Shoto took a needle and put the liquid in Nezuko's body. "What does that do?" Inosuke asked "WILL IT HURT NEZUKO-CHAN?!" Zenitsu yelled "no, before I found out how to turn into human form and demon form I used this liquid to walk in sunlight, it's call sun resistant serum so now Nezuko can walk in sunlight for now it will wear off at night then she will have to take the injection again every morning" Shoto explained "wait Nezuko can walk in the sun now?" Tanjiro asked "yup, Tamayo-san and Yushiro-san have the serum too I gave it to them last week when we first met, I heard Nezuko and Tanjiro have already met them" Shoto said.
