Brothers are both the first breath-users as both breathing forms cannot exist, without one another. The Sun awakens the Mark, first, while the Moon resonates, the rest will follow. [hider=Breaths][sub][h1][center] [color=black]'日'[/color] [color=crimson] '日' [/color][/center][/h1][/sub][center][sub]Sun Breathing, Hi no Kokyū[/sub][/center] Sun Breathing shares its status and origin with Moon Breathing as the first breath to exist, it has 13 forms and goes by [b][color=crimson]Hinokami Kagura[/color][/b].

[b][color=black]D e r i v a t i v e s:[/color][/b] [color=gold]Thunder Breathing[/color], [color=forestgreen]Wind Breathing[/color] [sub][center] [color=black]'Breathing Styles'[/color] [color=gainsboro] 'Breathing Styles' [/color][/center][/sub] [Color=Gainsboro][url=https://kimetsu-no-yaiba.fandom.com/wiki/Breathing_Style]Breathing Styles[/url] more or less, are similar to Canon; visual graphics that mimic the [i]elements[/i] based on ones swordplay, fueled by [url=https://kimetsu-no-yaiba.fandom.com/wiki/Total_Concentration_Breathing]Total Concentration Breathing[/url], and in our AU, by the time Demon Slayers reach the Hinoe rank, the elements become real and similarly functions to that of Blood Demon Arts. This is to end the divided Fandom & Player debate regarding preferences of which is preferable and I believe that such exception, justifies the power of the Hashira and those of Hinoe rank and beyond. With proper caution and commonsense, said real elements will have close moderation despite anime physics.[/color] [sub][center] [color=black]'Breathing Forms'[/color] [color=gainsboro] 'Breathing Forms' [/color][/center][/sub] [color=Gainsboro]No Player will add new forms to Sun & Moon Breathing, since both canonically got the most numbers, Players are still welcome to add new forms to any pre-existing styles, let alone make an entirely new Breath, minimum 3 to the premade while we will allow 5 forms for an entirely new style. Forms made by the canon like how Giyu and Zenitsu had done so, are available and used for practicality.[/color] [sub][center] [color=black]'Demon Slayer Mark'[/color] [color=gainsboro] 'Demon Slayer Mark' [/color][/center][/sub] [color=Gainsboro]No Player is going to have the [url=https://kimetsu-no-yaiba.fandom.com/wiki/Demon_Slayer_Mark]Demon Slayer Mark[/url] from the start & that means null as I will not be accepting even those who are born with it. The Demon Slayer Mark will claim your life at 25[sup]yo[/sup] and the only exception is; if you're born with it, allowing you to live up to 80[sup]yo[/sup] or becoming a Demon, which I keep a close watch as I will be the one to choose who gets it first. I have the right to decide on which Players are born with the mark alongside Sun Breathing. Red Nichirin Blades are a no-no from the start. For one to awaken the mark, Sun & Moon must awaken together, the rest will resonate.[/color][/hider] [color=Gainsboro][sub][center] [color=black]'Demon Slayer Corps'[/color] [color=gainsboro] 'Demon Slayer Corps' [/color][/center][/sub] The Demon Slayer Corps has been fighting Demons since the Sengoku Era & had gone many reforms to adapt to their battles. As of the 1980s – the Demon Slayer Corps are still an underground organization, outlawed by Funachi City's Mayor yet discreet enough to operate upon client demand. Demon Scientist, Yushiro, works alongside the Corps and Demons that're created by him. [sup]Factions Within The Corps[/sup] [hider=Factions][b]Butterfly Mansion[/b] - Honoring the Kocho Sisters & Tamayo, the Butterfly Mansion then became under the ownership of Yushiro and all [url=https://kimetsu-no-yaiba.fandom.com/wiki/Kakushi]Kakushi[/url] works for him. [indent][b]Medic Unit[/b] - This branch of Kakushi are the Canon versions, we all know and love. [b]Barrier Unit[/b] - These are Kakushi who are trained to wield Yushiro's items & their role is to hide the Corps' whereabouts, Fūinjutsu is their specialty. [b]Ranger Unit[/b] - Battle Oriented Kakushi, wielding Yushiro's offensive items & Nichirin Firearms, their specialty is shooting.[/indent] [b]Rengoku Clan[/b] - One of the pioneers and among the most influential clans in the Corps, known for Flame Breathing, History Archiving and Restaurant Owners. [b]Kamado Clan[/b] - Known to produce users of Sun Breathing, the intellectual successors of Yoriichi, not by bloodline. [b]Tsugikuni Clan[/b] - Known to produce users of Moon Breathing, cuz unlike Canon, Michikatsu in our AU was able to pass his Techniques prior becoming a Demon. [b]Uzui Yakuza[/b] - A yakuza shinobi clan who dominated the underground scene of Funachi earning their money through their generous protection rackets, gambling, prostitution and sale of illegal weaponry. Outside of their city, they are known for their powerful members with distinctive Wisteria style tattoos on their back. Underground they serve as the warriors on the fight against the demons who either live on their own or join smaller criminal groups around the country. [b]Ubuyashiki Zaibatsu[/b] - A zaibatsu whose origins goes as far as the Heian Era. They are known for their role in preserving Japanese culture in the face of modernization. Their businesses most prominently include land development, insurance and security firms, medical equipment, bars and the sale of novelty pieces through their craftsmen. Underground they served as the financial backers of the Demon Slayer Corps providing them with tools, weaponry and information for potential demon sightings.[/hider] [sub][center] [color=black]'Organization Hierarchy & Functions'[/color] [color=gainsboro] 'Organization Hierarchy & Functions' [/color][/center][/sub] [hider=Ranks]The Ranks mean seniority and subordination relationships. [b]Titles[/b] Oyakata means Master Oyabun means Godfather The Oyakata is the leader of the Demon Slayer Corps while the Oyabun is the leader of the Uzui Yakuza, these are the two faces of the Corps. Hashira is self explanatory. [b]Ranks[/b] Ranks this time go by Organizational Function besides power levels. [b]High Tier - Mayonaka[/b] The Mayonaka is a tripart ranking ladder, who goes on dangerous missions and during the day, they help the Uzui Yakuza with the more arduous tasks like Debt Collections and Escorts. Kinoe Kinoto Hinoe [b]Mid Tier - Tasogare[/b] The Tasogare is a tripart ranking ladder, these are the majority of the Corps' work force, during downtimes, they'd work for the Ubuyashiki. Hinoto Tsuchinoe Tsuchinoto [b]Low Tier - Hiruma[/b] The Hiruma are academically inclined, learning about Demons and the business world, by Kanoto rank, they will join the Final Selections and be promoted to Tsuchinoto and since this tier is almost non battle Oriented, they help earn through community services by Ubuyashiki.

Their growth in power is defined as the longer they live, the more they fight and eat, the stronger they become. So lethal, they have freewill, hence unpredictable. [hider=Yatsuchizuki][sub][center] [color=black]'八血月'[/color] [color=gainsboro] '八血月' [/color][/center][/sub] The Yatsuchizuki aka 8 Blood Moons are the strongest Demons of Michikatsu, and they take after their Master, none of them will die from decapitation & to defeat a Chizuki, it's either a stall until sunrise, Wisteria poisoning or Red Nichirin Blades. For 60-years, the Yatsuchizuki has minimal changes, there's rarely ever an attrition to the ranks and Michikatsu. The Yatsuchizuki are defined as Yakuza Lords, and are scattered, stationed in each region of Japan. To Humans, they appear to be more than just Humans in disguise but Japan's biggest crime syndicate. Whereas, their King is the Mayor of Funachi City. [b]The Four Demon Lords[/b] The Four Demon Lords are Michikatsu's immediate successors, they are given the task to control each region of Japan. They're Michikatsu's own Upper Moons, and beyond conquest, their penultimate mission is to kill the Demon King in a Yubikiri, meaning promise renouncal via succession. None of them succeeded in becoming the next Demon King. [b]The Four Demon Consorts[/b] The Four Demon Consorts are Michikatsu's all girl band & his version of the Lower Moons. Otherwise known as the Rasetsu, these Demons are special since they are capable of producing offspring. Any child borne from their progeny will be fullborn Demons and not hybrids. Unlike the Demon Lords, Michikatsu's designed them as wives for his Demon Lords. [b]Blood Rite Battles[/b] A Demon Lord cannot be a Consort and neither can a Consort be a Demon Lord, for these are gender confirming roles. Ranks, however, inside their group, commences the Blood Rite Battle. [/hider] [hider=Mangetsuki]A Mangetsuki is a High Level Demon, often serving as Regents of each Chizuki & unlike their Demon Lords and Demon Consorts, who wear formal clothing, these are the modern day Yakuza thug that one would imagine, they got the tattoos of human blood, a perfect reference to Yakuza culture, as they're also missing a pinky finger, it's moreo so they can't regenerate it. [/hider] [hider=Senrantsuki]These are the World War 2 Demons, suffering radioactive mutation, they're beyond reason.

Common Sense, I need not explain what's permissible and what's not, I expect you to have the decency to read between the lines. 2. I will only allow two Demon OCs. As in Players. This will be changed if the RP gets better and better. 3. BDA should at least be Rui's level up until Hantengu. Use your imagination.

[b][u][sup][color=red]S h o w a S e c r e t[/color][/sup][/u] :[/b] Brief backstory, unlike Muzan's demons, Michikatsu's demons keep their memories and aren't bound to a Killswitch, explain why do you side with the new Demon King, etc. one of the reasons as to why many would side with him, is because he treats his subjects better than Muzan do. Being a demon in this age means you're a Yakuza.
