All the Ocs on here are Osomatsu Ocs. Maybe I'll add my ocs from other fandoms at another time, but these are just the ones I have for that! This list is also incomplete, and some of the art is VERY OLD!!!!

Here is my au in as much detail as I am humanly able to muster at this time.
More characters may be added in the future, but I feel as if this is a pretty comprehensive rundown of what anyone would need to know about my au.

Ryuumatsu Lore

In what would soon become home to modern-day Akatsuka Ward, two powerful, benevolent dragons once watched over a small region of Japan. One was known as Matsuyo, and the other Matsuzo. Together, they kept the villages in their region safe from invasion, monsters, pests, etc. Matsuzo was guardian of the day, and Matsuyo was guardian of the night. The only time the two dragons would see each other was at dawn and dusk, when they would exchange their watchposts. Over the years, they fell in love, and Matsuyo eventually bore six sons. These sons were Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and Todomatsu. Life was difficult, as only one parent could care for all six at a time, and figuring out how to balance the care for the young ones while trying not to exhaust them was hard. It was so difficult that by the time the young dragons had grown to maturity, the once beautiful dragon duo had grown older from the stress and were too exhausted to watch over the land anymore. They left to go live high up in the clouds, leaving their sons to live on the peak of a mountain near the village. Sometimes, they come down to see how the land and their sons are doing. They are often disappointed.The Ryuumatsus are immortal and forever stuck at their prime adult years. This could be changed through extreme stress, such as what their parents went through, or potentially, if they lost a loved one. Extreme, prolonged stress is the only thing that can make immortal dragons like them age.Their natural-born powers include flight, invisibility, telekinesis, shape-shifting into a more draconic form, and fire breath. They also have their own powers that are unique to each of them. Osomatsu's fire burns hotter than everyone else's, Karamatsu has much more skill manipulating water than his brothers, Choromatsu has a higher level of control over the clouds/weather, Ichimatsu has a healing ability that is unique to just him, Jyushimatsu can enhance the strength of those around him, and Todomatsu is able to make any living being feel more energetic and refreshed.The Ryuumatsus try to take on the responsibilities of their parents, but they can never seem to get it quite right. A feral boar monster wreaking havoc hrough a village is something that either Matsuyo or Matsuzo could have dealt with effortlessly, but whenever the brothers try, it always ends with near total disaster. Even as centuries pass, the brothers never seem to get any better at doing their jobs, even with an entire six of them watching over the region instead of just their two predecessors. Despite this, because of their power and status as mythical dragons, they were revered as gods and have their own shrines/temples on the mountain on which they live. However, no human can ever find their home on the tip of the mountain, as it is hidden to all but those granted access. You would simply see nothing on the top of the mountain unless one of the dragons granted you the ability to see and touch it. Each brother had their own flaws that made them inadequate guardians:Osomatsu
- Greedy, would sometimes straight up steal from villages if he didn't get enough offerings
- Inattentive, sometimes not even noticing when disaster struck because he was distracted by something else
- Lustful, be would rather ogle pretty human girls than actually watch out for danger
- Drunkard, he would get drunk whenever he got his hands on alcohol (whether it be offered or stolen), and he would be too drunk to properly deal with threatsKaramatsu
- Superficial, gets too caught up making either himself look good or worrying about how things look, sometimes ignores the bigger picture, can be inattentive to actual issues as a result
- Ineffective, when he does take action, he often doesn't know how to, and tries to make himself look cool while solving problems he has no idea how to handle. This obviously results in him failing in spectacular ways
- Prideful, unwilling to admit his mistakes if he thinks it'll make him look badChoromatsu
- Lustful, like Osomatsu, he can get distracted easily by the sight of people he finds attractive
- Flusterable, he can more easily become flustered or baffled, causing him to be unable to do his job effectively
- Wrathful, can get too angry and spiteful towards his brothers to focus properly on his jobIchimatsu
- Reclusive, he is prone to be reluctant to actually help if there are too many people around, because he doesn't like to be seen by most humans.
- Unsympathetic front, will pretend to not care about things in front of humans he does encounter, earning him a reputation of being an angry god. Funnily enough, this leads him to have more people leaving offerings at his shrine to try to appease him
- Flusterable, like Choromatsu, he can get flustered and be unable to properly focus. This usually happens if he gets praised too much.Jyushimatsu
- Reckless, tends to cause destruction as he tries to prevent it. Often this is because he tries to overkill any threats.
- Hyper, constantly all over the place doing random stuff unrelated to his job. Ironically, he actually tends to spot threats before everyone else because he is still on the lookout for it while he's messing around.
- Overeager, will attack things just because he assumes they are threats. Has almost hurt the people he was supposed to protect multiple times because of this. He has a reputation as a dangerous god because of this.Todomatsu
- Superficial, like Karamatsu, he is often focused on appearances. He can be hesitant to fight if he thinks he'll get dirty. At least he usually sticks around after a threat is eliminated so he can help clean things up if he feels bad enough about it... Even if only to flirt with attractive people.
- Jealous, he sometimes steals offerings from his brothers's shrines out of jealousy if they get more than he does. This can cause infighting between the brothers.
- Petty, will sabotage attempts to ward off threats if he wants to be the one to do it instead. This often ends badly.Despite all of their flaws, they have managed to at least avoid total destruction of their region. As well, they are for the most part viewed pretty positively by the people of the region. Whenever they show their faces, they are treated like celebrities or kings. However, as the centuries went on and the region was better able to protect itself, they became less and less needed and recognized. In the modern age, they are nearly treated like normal people, which most of the brothers actually don't mind, since they can just laze around and only help a couple of people since there are no major threats anymore. Even the monsters have given up on being so evil, the more intelligent ones just living day-to-day like a normal person, with a little mischief now and then. Oni that would have been fierce foes back in the day have become drinking buddies for the ancient dragons. Trickster Kitsune have become gambling partners. The majority of supernatural beings have become quite mellow over the centuries. The only things to worry about are things that are mostly out of their control anyways, like foreign affairs.The Ryuumatsus retain much of the same personality traits as the originals, though obviously their behavior is modified to suit their scenario.Each Ryuumatsu has their own preferred kinds of offerings and "blessings" that they will offer in return (these blessings are not by any means guaranteed to happen). The blessings with parentheses after them are "false" blessings that they need to actively make happen, and the ones without them are ones that they can naturally do without interfering directly.Osomatsu:
Offerings- Alcohol, meat (raw or cooked), money
Blessings- Will increase your luck (often by purposeful intervention rather than divine power), make your alcohol more potent, increase fortune (by stealing from other places most of the time lol)Karamatsu:
Offerings- Alcohol, grains, precious fabrics and stones.
Blessings- Attractiveness boost (this is a total placebo effect), charm increase (also a placebo), self-love increaseChoromatsu:
Offerings- Alcohol, bread or rice (cooked), artwork and poems
Blessings- Inspiration (will literally just be out of sight whispering to you), visions (totally not a hallucinogenic plant he slipped in your food), will bless their crops to have a more bountiful harvest.Ichimatsu:
Offerings: Alcohol, sweets, cat-related items
Blessings: Will attract more cats to your house (he will literally just bring you cats), will keep pests away from your property or crops (adding more cats), and will heal your sick cats... and fine... Your children too. No promises, though....Jyushimatsu:
Offerings: Alcohol, food (any kind), sports related items that have been used to win games
Blessings: Luck in sports (will purposefully interfere with aspects of the game), luck in gambling (rigs the game in your favor using his powers), strength enhancementTodomatsu:
Offerings: Alcohol, pigments, precious fabrics/stones
Blessings: Luck with romance (just asks people to go out with you behind your back), clear weather (clearing out the clouds with his powers for a short while is easy enough), and more beautiful gardens.Osomatsu, Karamatsu, and Todomatsu interact with humans the most. They can often be found at their temples if they are called for, or bribed with a big enough offering. The other three brothers are a bit more elusive. In the modern day, only the most devoted spiritualists make regular offerings at their temples.The other side characters exist here as well!Iyami is a gluttonous oni who likes to trick people and steal money, alcohol, and food. Even in the modern age, he still continues to steal from the Ryuumatsus' shrines, causing a lot of clashing between himself and the brothers. Unlike the Ryuumatsus, he can age, but very slowly. By the time the modern age comes about, he is much weaker and older than he used to be.Totoko is a more humanoid, immortal Akugyo. She often stays in the sea or in the local bodies of water, but when she does come out, she normally takes on a slightly more human form, though her fish features are still noticeable if she's wearing short sleeves. She is incredibly durable and an adept fighter. She has given all six brothers a run for their money whenever she's decided to raid their land out of spite. In the modern age, she seeks fame and wealth rather than bloodshed.Chibita is a Tanuki. He's always been relatively benevolent, only being a mild trickster. He has a human disguise, but if he gets upset, his Tanuki ears and tail can re-manifest. Around just the brothers, he is usually comfortable being in his pure Tanuki form. He works as a sort of watchman for the brothers, not out of respect for them, and not for the pay (he doesn't get paid), but because he knows (begrudgingly) that the Ryuumatsus are the best bet for keeping the region (relatively) safe. He uses his Tanuki powers (......Balls) to make his oden cart. Rest assured though, the food is real. In the modern day, he is simply an oden seller, as he found that cooking and selling oden was his true passion.Nyaa-Chan started life as a normal cat, but after many many years she became an intelligent, powerful bakeneko. She decided that she wanted a life beyond being a housepet, and took on a human form. She lived as the daughter of the old couple who raised her, and worked as a geisha so she could earn enough money to allow them to live comfortably in their old age. She continued to support them until they died. It took her many years to finally recover from the grief of their passing, during which time she travelled all over Japan to try to find inner peace. Eventually, she came back and settled in the village that had been her original home. She continued to be an entertainer, being able to stay in the village unsuspected of being a bakeneko by pretending to grow old and die every hundred years or so, while simultaneously pretending to be her own daughter that was growing up. Usually, nobody questions the fact that the mother and daughter are never seen in the same place...
In the modern day, Nyaa-chan works as an idol, just like in the normal show. However, she has a reputation of being from a long line of entertainers, all doing different things. Being an idol is only her current profession, she will likely move on to some other entertainment form after her current "life".Dekapan is an eccentric scientist who started as an alchemist trying to create the philosopher's stone. Through some miracle, he managed to create it, but it was tiny. A freak accident resulted in him swallowing it, which caused him to become immortal as a side effect. It took him an absurd amount of time to figure out that this was the case, but when he finally did, he decided to completely dedicate his immortality to being a scientist. Despite having already lived almost a thousand years at this point, he hasn't really made any significant scientific breakthroughs.Dayon is a slightly more human-looking Ijū. Like a traditional Ijū, he is rather harmless, just having a large appetite. He is the one who caused Dekapan to eat the philosopher's stone, and he swallowed some residue of it in the same incident, which also caused him to have immortality. He used to live in the mountains, occasionally begging for food from passerby, but he lives with Dekapan now. He pesters him and others for food quite often, and can be destructive if he gets too hungry.Hatabou is an oni like Iyami is, but he is considerably smaller. That being said, while he definitely acts like Iyami (at least in the ancient eras), he has an unfortunate habit of causing casualties during his raids, usually by complete accident. Granted, he doesn't really care, nor does he regret it. Despite this, him and Iyami don't seem to get along too well, mostly because Iyami sees him as an annoyance when he's trying to do his own raids. In the modern day, he still manages to cause at least near-fatal accidents.Atsushi is a Kitsune who lives his life disguised as a human. He is prone to stealing small objects with little value and pranking people. He tends to move between different towns and villages, shifting how he looks just slightly each time to not be recognized. He only enjoys harmless pranks, not ones that would get anybody hurt. He just likes to see the confusion and frustration on people's faces. His favorite places to frequent are the red light districts of any major cities and anywhere that alcohol can be found. He doesn't normally participate in any of the activities in the areas he frequents, he just likes to find new prank victims among the intoxicated. In the modern day, he owns his own nightclub.The Riceballs come together to form an automaton of a Yogen no tori, though they have more humanoid forms that they can shift into where they can be two separate beings. Being able to predict the future, they often try to warn people about upcoming disasters, but they are ignored most of the time. They were one of Dekapan's creations. They were created as an attempt to make a Yogen no tori that would constantly be around to predict things, to replace the elusive, genuine one. Ironically, once they gained self-awareness, they ran away. Their power source is unknown, though it is speculated to be some kind of object placed inside of them by Dekapan himself. In the modern day, they have upgraded themselves and try to seek out entertainment.

This au is not focused on any one specific time period! The whole point is that the brothers are immortal dragons, so I don't want to focus on just the past or the present. I will likely depict them in pretty much every time period!Boundaries for my au:No:

Well, it is if you don't care about my ocs, but if you're at least a little interested I made some versions of them (at least my two main ones) for this au as well.Kass is a Kumiho that migrated to the region of Japan the Ryuumatsus watch over in hopes of finding a means to become human. Normally, a Kumiho becomes human once it has refrained from eating human flesh for 1000 days. For some reason though, even when he had succeeded in this task, he has not turned human. He has entirely lost his bloodlust by the time he moves to Japan and has tired himself out trying to become human. He lives right at the edge of a highly populated town, and lives a fairly normal life. He pretends to be a Kitsune, as they have a much better reputation than the Kumiho does. Even so, most of the time he keeps a human disguise when going around humans. In the modern day, he has given up becoming human entirely and is actually quite happy the way he is.Yuudai is an elusive Kitsune who lives alone in the mountains. He is a very self-reliant person and prefers to be isolated, but he does have a mischievous streak. He likes to play petty but harmless pranks on unsuspecting humans and supernatural creatures alike. When he finds someone he genuinely likes, he can actually be quite affectionate. He has a soft spot for children and refuses to prank them. He is one of the few non-evil creatures to despise the Ryuumatsus, mostly because he thinks they're annoying (true) and incompetent (also true). He has a human disguise that he uses to go into the nearby town. In the modern day, he still lives fairly isolated.
