‡"Truth of the past"‡

{time skip}

Inosuke is now 14 his now training with Akaza they were in the forest filled with thick trees perfect to shade Akaza while training Inosuke"make sure to keep to never lose sight of your opponent" Akaza yelled while training and teaching Inosuke "What should I do if my opponent is stronger than me like you uncle Aka?" Inosuke asked "use all your strength if you cannot win then escape and come back even stronger and beat them up" a man said as Akaza looked at Douma as Douma stopped to look at Akaza (Inosuke knows the truth) "Dad!" Inosuke went and hug Douma "Hey Inosuke I've brought your lunch your Mom will be here in a bit she went to go do something so I came ahead" Douma said as Inosuke smiled "I was starving thanks Dad!" Inosuke took the stacked bento boxes as he opens them while Akaza comes to help Douma get the picnic prepared "Hey Kiddo be patient till everyone's here!" Akala said as Inosuke pouts and put the open bento boxes on the blanket as everyone arrived shortly

"My my your cooking is the best Kotoha!" Daki said as she eats with joy (demons can eat things that contains meat and blood it can be cooked or not) "thank you for the compliment" Kotoha said with a smile as everyone's eating happily

{In a different place}

"Kagaya-sama you have summon us?" A group of swordsmen said as they just showed up without making a single sound "Yes we have located a group of upper demons they might be the upper moons the demon woman you've captured said we must finish them now when the sun is still with us" The man said with a cold tone as the group of swordsmen known as the Hashiras responded with obedience "As you wish Kagaya-sama" as they disappear without a trace

{Back to the lovely Demon family}

As everyone was eating peacefully one of the hashiras sent by Kagaya the fastest of them all the insect Hashiras Shinobu along with the wind Hashira Uzui Tengen "so that's them?" Tengen said "I guess" Kocho Shinobu replied "if Kagaya-sama didn't tell us we would've mistaken them as normal human family or mythical creatures for they're exceptional beauty as the demon we've captured described us" then another Hashira showed up "but those two there aren't demons they're humans" the water Hashira Giyuu Tomioka "my Tomioka-san we already know" Shinobu replied but she was actually lying since she likes annoying Giyuu but Giyuu ignored Shinobus provocations "I have a theory what if those upper moons keeping those two as hostage I mean they're higher rank demons it's most likely they'd do this because it's daytime and that demon over there" Giyuu points at Muzan

{To the demon family}

"Muzan-sama are you sure we shouldn't just get rid of them?" Kokushibo whispered to Muzan "let it be Kokushibo they're weaker anyways and even if it's daytime were vulnerable we just are limited and anyways were in a thick forest we have an advantage they're just stupid humans" Muzan replied as Kokushibo nods and continues to enjoy the picnic

{Back to the three stalking Hashiras}

"I'm curious as well with that one as well the demons we've captured so far never mentioned him much more he doesn't have any numbers on his eyes" Tengen said thinking with such curiosy "Let's focus at our target's instead good thing all six of the upper moons are here" Shinobu replied "Then Iets go back to headquarters" both agreed to Giyuu as they left

{To the demon family}

"They've finally left" Akaza said in annoyance as Gyutaro sighed "huh?" Kotoha blurred in confusion "What do you mean Uncle Aka?" Inosuke asked confused "Well they're were actually those people we told you spying on us a while ago" Douma said unfazed "you mean those demon slaying guys!?" Inosuke exclaimed "Yes well they do not know that they're actually two kinds of demons" Muzan said as Inosuke looked at Muzan "What do you mean by that Grandpa?" (Muzans in his male form since Inosuke and Kotoha know) "Well back then I was a human too but I was frail ever since I was born I was almost claimed dead because I was hardly breathing" everyone stayed quiet listening to Muzan the upper moons frowned as they have heard Muzans story and felt anger and sorrow "it was a miracle I was able to survive in my infantry, I was told I'll never survived till I was twenty I accepted my fate but then a doctor came saying he can cure me but I never knew he'd turned me into a monster" Muzan said as Daki spoke "Okasa your not a monster!" "She's right if it wasn't for you we-" Muzan shushed Hantengu "Father" Kotoha said as she looked pained how Muzan called himself a monster as Inosuke went and hugged Muzan (Kotoha and Inosuke calls Muzan depending which form he takes they don't know about his child and real form) Muzan embraced Inosuke as he continues on "I continue to follow the doctors instructions though he died in an accident that same day I started feeling off my body was changing and I was in great thirst of blood and flesh not just any kind of flesh but human flesh I bit myself to snap myself from killing anyone and fled secluding myself" everyone gotten serious as Inosuke continued to stay in Muzans embrace "I learned that I wasn't able to go in the daylight which I was very glad of but now I don't need to eat flesh or blood I was eating wild animals in the forest when I have met another demon like me but that demon was actually turned into one, one with no rationality he was lost his humanity that day was when I learned that it was not me that the doctor turned into a demon they're were more and then I chose to eliminate every demon he had created but they're was one problem" Muzan paused "They cannot die no matter how many times you stab or try cutting they're heads off back then only the sun is what I know that can kill demons but it's still risky so I couldn't kill that demon but I thought of one thing eating the demon" Muzan said as everyone was quiet "they're was no choice he was no longer human he was now a man eating demon so I ate him it was not hard it seems the demon I ate was an error but for me I kept my humanity and rationality I then felt stronger after eating that demon I continue to tract other demons but they're were to many of them I started to think what if that doctor didn't died because only he can create demons and I've been eating demons for a decade then I thought of searching for the doctor what happened was it really an accident or not? Is what I thought and I found a lead on him I tract him and found him he was no longer a human he was now a demon himself" Muzan paused again as Inosuke trembled in anger "He was shocked to see me the only demon that didn't go crazy after being created before him as he was laughing like a maniac I was enraged when he told me how he had kept on creating demons to find a secret to immortality and that he tried doing it himself saying he was now a nearly a perfect being just needing one final thing but then I showed up showing how I am the demon he was looking for the first perfect demon but I was actually not after knowing he went insane they're were many humans at the time and he started going mad killing everything I went ahead and started doing what I've been doing to kill demons fighting them till they're weak and eating them it was intense because unlike him he ate humans while I ate those errors he created but I was successful but they're were many people in severe condition's and they're was no doctor and I thought what if I gave them my blood I saw the doctor putting his blood into an elixer meaning it may be how he created demons so I asked consent to the humans that were about to die as I told them the consequences and that they may live but can become irrational after but they agreed because they have a family waiting they said" Muzan said his voice trembling
