Breath of The Sun

The Truth Reveled and a New Student

Flashback Three years ago, the sleepover Izuku's POV: 

          After my parents went to sleep I got everyone and told them we are going to have a meeting. 

          "So what is it we need to meet about?" Katsuki asked. 

          "The truth about what I intend to teach you and its true purpose," I told him as I did I pulled out an old, old book. "This estate and everything on it was originally used by an underground organization. That's sole purpose was to eradicate beings that eat humans, the organization's name was The Demon Slayer Corp. The Demon Slayer Corp was founded at some point during the Heian period shortly after the first demon was born and became the Demon King. Around 500 years after its founding a Hashira joined the ranks of the demon slayers and created the foundations for the breathing techniques leading to the golden age of the Corp known and documented as the Sengoku era which lines up to around the Edo period in our normal history." 

          "Wait you seem to speak of this as if it is fact?" Kirishima asked me. 

          "Well if they aren't around anymore does that mean that the Demons were eradicated?" Mikumo asked. 

          "Well it is true Kirishima, as for your question Mikumo the Demon slayer are not around anymore because they thought that the did indeed win." I said calmly which caused them to relax a bit. "The final Battle against the Demon king happened well after the Sengoku era in the Taisho period and not much is known other than he was ultimately slayed by The Ronin Demon Slayer Kamado Tanjiro. Using the very same breathing form I use today it was claimed he died in the battle though his body was never found."

          "And your point is?" Jirou asked. 

          "A demon is born when blood of the demon king is shared or injected in some way into a humans body," I said "and since his body was never found I suspect that in the battle with the Demon King Muzan Kibutsuji, the king left every ounce of his blood to Tanjiro Turning him into the next Demon King. One who kept his operations in our country relatively underground." 

          "And you suspect this because?" Kaminari asked. 

          "Have you all heard of the disappearances that happen everyday or events of horrible massacres that occasionally pop up on the news?" I asked them they all nodded. "These events all share large amounts of traits resembling Demon attacks described in the archives. So I ask you all to keep this in mind I will train you regardless but I ask that you all be prepared to become new Demon Slayers in the future, do you all think you can do that?" 

         "I'm with you brother!" Izumi said. 

         "I promise to do my part so long as I will be protecting people," Mikumo said. 

         "Yeah this sound so manly!" Kirishima said in excitment. 

         "Just be sure to train us well Izu," Katsuki said. 

         "Yeah I'll do my best as well Zu-Zu," Katsumi said. 

         "I'll do my best to be the hero everyone needs," Jirou said finally. 

Back to the present Aiba Manami POV: 

          I wasn't born normal, I know that that's rich coming form someone who lives in a society where the norm involves supernatural abilities but I'm still abnormal. See I was born with a quirk that's true, my quirk is called Love I can boost the power of the person I love by telling them out loud how much I love them. The intensity of my love effects how much I boost them, beyond my quirk I was born extremely flexible and an odd mutation in my normal genes affects my muscle. My Muscle fibers are around eight times denser than then the Average person.
