The Pillars

Shinobu Kocho - Upper Moon 4

Known as the Lady Butterfly, mistress of poison, she who had slaughtered Slayer after Slayer in single strokes. Some say the last thing you hear is a woman’s soft laugh and the flutter of butterfly wings.

Possesses a body that looks like an amalgamation of a human and a variety of deadly insects, particularly butterflies.

Her skin is deathly pale, transparent to the point where you could see her organs. Her limbs and back billow with purple monarch wings, though the rest of her is scattered with toxic spines. And hen she opens her mouth centipede’s mandibles scuttle from it, and her eyes are the compound eyes of a butterfly, bright violet and all-seeing with the number 4 carved into every facet. When she speaks, there is a chorus of wasps in every breath.

Instead of poison, the demon Shinobu being organically an insect as well now uses natural venoms.

Her Blood Demon Art is based on Shinobu manipulating her blood and turning it into various types of venom, each mix deadlier than the last. Unlike her Pillar self, who was limited to whatever poison she had in her sword sheath, her demonic self has virtually no limit on what she can create.

Her most powerful blood technique is known as the Hundred-Thousand Sting; she deploys her worst venoms with her own unaltered blood in the form of an extremely corrosive mist that once you breathe in, you’re a goner. If it touches you, it will seep in, and you’re a goner. If you’re so much in the range of the fog, you’re still a goner.

While outstripped in strength by Gyomei, Sanemi, and Muichiro– Shinobu still proves herself an exceedingly deadly opponent through speed and intellect.

Her personality as a demon is a mangled representation of her traits as a human; while seemingly calm and sweet, Shinobu holds the exact same demeanor while brutally killing others. But she is also notoriously quick to anger, sending her into furious fits as she attempts to reign it in. Make no mistake though, she is still wickedly clever.

As a human, she’d been cared for by her demonic older sister Kanae after their parents were killed and her sister forcefully transformed into a demon by Upper Moon 1 Gyomei Himejima.

Kanae had managed to resist the hunger for human flesh to be able to care for her sister– mercifully spared by Gyomei as she reminded him of a child from his human past.

Shinobu had desperately wanted to become a demon just like Kanae so that they could truly live together, though Kanae always rebuffed her– until the arrival of the Pillar.

The Snow Pillar, Doma. He had battled Kanae under the accusation that she had killed their family and paid no heed as he beheaded her in front of her terrified human sister. Maddened with grief, Shinobu drank her sister’s blood, vowing vengeance on the Snow Pillar.

It was Upper Moon 1 who found her, having been originally sent to recruit Kanae into the Moons. Seeing that Shinobu was far more bloodthirsty and willing to kill, he took her in instead.

Up until now, Shinobu hunts for Doma, and takes special care to kill any Slayer with ice or snow-related techniques slowly. A refinement of her most agonizing of venoms just for him.

Mitsuri Kanroji - Upper Moon 6

This one is insane.

She is Love, she is made of Love, and she will Love and Love and Love and she will take their Love as well until there is nothing left to Love.

It is said that Mitsuri is the kindest Demon Moon, taking her prey with the greatest expressions of Love that they could ever receive. But do they, really? When Mitsuri loves them with everything she has– from her horrific strength to her blood to her insatiable appetite?

Mitsuri is fond of shapeshifting, though her true form is… that of a normal human girl, albeit with pink skin, white eyes and a fanged mouth. She even keeps the unusual hair she had detested her whole human life. Did you think this embodiment of unquenchable desire would be a little racier?

When Mitsuri kills and devours, she does so in every way of loving that she can. She will embrace you until your spine gives way, she will kiss you until your lungs collapse and your lips are torn to shreds, she will lie with you until all is spent and blood seeps from every part of you.

It upsets Mitsuri so that her Love isn’t returned adequately. But she is a forgiving demon– so she will continue to express this devotion to every being until it is returned in full. Not even other demons are exempt.

The number 6 is written in careful script over the pale surface of her eyes. It is watermelon green and pretty and the last thing most of her prey see.

Her Pillar self believes in love, sweet and gentle and ultimately ephemeral. Demonic Mitsuri believes in giving and taking until there is desire to love anymore.

It was what was promised to her, when Muzan fed her his blood from the palm of his hand. She had been rejected for her hair, her strength, her need to love and be loved.

He had found her, cast out and alone, just one cruel husband after another. Muzan promised her that demonhood would let her love for all eternity, that in his world she would never be rejected. Mitsuri agreed. Can you blame her?

As an Upper Moon, her already prodigious strength has made her nigh on par with Sanemi and even Gyomei. Her flexible body surpasses superhuman limitations and weapons simply sink harmlessly as she softens her body to the blows.

Her Blood Demon Art, however, is not focused on her physical ability. If it were, she would have been placed lower on the rungs of the 9 Upper Moons. No; her blood is one that makes the mind bend and dance to her will. Love and aphrodisiacs. One whiff, one taste, and it’s all over. There is only love.

The pinnacle of this technique is her Eternal Ecstasy, where wounding her is suicide in itself if she does not cut her own flesh open first. Her blood becomes incredibly potent and drives men and women alike to madness in their desire to be loved by her– they will kill each other and let themselves be killed by Mitsuri if the initial violence doesn’t get rid of them initially. Her blood is the Marechi equivalent for humanity but is surprisingly more dulled towards other demons.

Await her battle with Hantengu. He thinks himself incapable of love, his Pillar’s skill and impeccable focus. He believes nothing will sway him, not even the rumored supernatural charm of Upper Moon 6. He secretly prays that it is enough when he draws his blade against her in the Swordsmiths’ Village.

The Upper Moons

Akaza (Hakuji) - The Destruction Pillar

For a Pillar, Akaza– Hakuji is a name he leaves at home for his wife– is unusual even for them.

While the Pillars carry weapons made of nichirin, ranging from blades to blunt force to guns, Akaza fights with his bare fists. It is the only sort of fighting that Akaza has known his whole life and he won’t stop now– not even as his fellow Pillars look to him in concern.

It doesn’t matter. Akaza’s happiest when he’s beheading demons with his own hands. He has gloves especially made for this, made from flexible nichirin, knuckles topped with the sun steel. Even his knees are capped in nichirin.

His breathing style? Some call Akaza a genius, some call him crazy. Either way, he had merged his adoptive father’s Soryu Style martial arts with breathing, creating the Destructive Kill Style. Before he had begun training in breathing, he had depended solely on his own natural strength, and this discovery of the Slayers’ method of combating the demons had raised Akaza’s power to almost how he had been as his demon self.

Hence, he is called the Destruction Pillar. It is an ominous title that, coupled with his roughened features and muscled frame, has even hardened Slayers steering clear of his path. His wife Koyuki knows better though, knowing him as grumpy Hakuji who had a soft heart under all the grit.

In the heat of battle Akaza is an unforgiving beast, relentless in his pursuit and merciless in his killing. At home, he is Hakuji; gruff and quiet but gentle in his selflessness, especially towards his dear Koyuki. Often you can find the Destruction Pillar walking beside his wife in the gardens, feeding ducks and sitting amongst the flowers.

While not tattooed with the criminals’ marks, shortly after becoming a Slayer Akaza had himself inked with a single bar for every ten demons slain. So far he has almost reached the amount of tattoos he has on his demon self.

His story remains nearly the same– but when Keizo told him that he was to inherit the dojo and marry Koyuki, it was not poison that came for them. When Akaza ran to his father’s grave, the two assassins by the well were beset upon by another; a particularly strong demon, a real one, killing then devouring the two before setting its sights on the father and daughter inside.

Keizo could fight, and he fought better than Akaza did when he first met him. He held off the demon just long enough for Akaza to rush to their rescue– only for fate to recall that Keizo had grown old, and he was never as blessed with endurance and strength as Akaza had been. The demon dealt a fatal injury, and Keizo fell.

In another world, Akaza’s hands were bloody with the scum of humanity. In this one, enraged he lunged at the demon and shoved both his hands into its chest. He obliterated its organs and yet… it was Akaza’s first demon, and this demon merely regenerated and laughed into Akaza’s face. In another world the blood had come from sixty-seven men. This time it was blood from the demon that he had killed sixty-seven times through the night. A demon could only be killed through nichirin or the sun itself; when Akaza tore its head off at his final attempt, the demon’s body simply gave.

Akaza collapsed out of exhaustion, and slept for three days. With Keizo dead and her fiance unconscious, Koyuki was in shock and was immediately wracked by a fit of weakness. It was only through the sudden intervention of the Moon Pillar that the couple were tended to; it had originally been Kokushibo who was supposed to slay the demon in their town and upon hearing that Akaza was fighting some unkillable enemy, sought a meeting with him.

It was Kokushibo and a worried Koyuki Akaza awakened to. After confirming that Koyuki was unharmed, Kokushibo then expressed admiration for Akaza’s fighting skill and offered him membership into the Demon Slaying Corps. Initially both Akaza and Koyuki refused. Why would they endanger themselves further with this talk of demon-slaying? But as Akaza thought of Keizo, who had died protecting Koyuki and with faith that his adoptive son would save her, he eventually agreed.

When Akaza rejected having a blade or weapon of any kind forged, Slayers shook their heads and muttered that Akaza would die. There was no Slayer in existence who had gone against Muzan’s spawn with their bare hands. But as they witnessed Akaza wrench off the head of a Lower Moon demon without the use of any weapon aside from his gloved hands, the whispers ceased altogether.

This time it is Akaza who is assigned to investigate the Infinity Train. Before every mission, he prays at the graves of Keizo and his father, kisses his wife goodbye. For some reason he prays a little harder, holds Koyuki a little longer– lately his dreams have been plagued with fire…

Doma - The Snow Pillar

This’ll be one of the only times I’ll not clown on Doma. Treasure it lmao.

Emotionless, capricious, and a known glutton for pretty women, Doma is an excellent Pillar and is frighteningly effective at killing demons. His being a moral citizen though is… highly contested.

As a Pillar, Doma lacks the cult he had as an Upper Moon, but he does have a loyal following of admirers from his pre-Slayer who believe him a sort of demigod for his pale hair and lovely rainbow-hued eyes. His charming personality and pretty face only serve to buoy his reputation amongst the populace as well– much to the chagrin of some of his Pillar colleagues.

Instead of a sword, Doma makes use of his fans; both are made of nichirin steel and hued gold in Doma’s hands. Despite their ornamented surface, they are razor sharp and can function just as well as twin short swords.

His is a pretty, almost gentle breath style; Breath of Snow is more a delicate dance in appearance than something meant for combat. And much like Doma, it is a death sentence to mistake beauty for the lack of deadliness– the Breath of Snow utilizes misdirection and inhumanly fast and precise attacks meant to cripple an opponent before the killing blow is dealt, with these strikes resembling the howling gales of blizzards.

More often than not Doma toys curiously with the demons he hunts, tossing them around with the nigh-invincible evasive ability of his breath before executing them, all in an effort to feel emotions. If the pleasures of human life could not elicit these so-called feelings his fellows had always talked about, then how about violence?

Pretty girls, pretty women; it’s not a real feeling that blooms in Doma’s chest (it’s hollow, Akaza hisses, hollow and cold as shit) but he enjoys them. Enjoys the rapturous expressions on their faces, from pleasure to fear to pain to happiness to despair– he puts his hands on their faces and smiles his best. The beatific one, the one that makes his eyes crinkle at the sides.

After his parents died, his father by his mother and his mother by himself, Doma continued to handle the cult, raised by devoted followers. He grew up the smiling, soulless leader of people he believed as foolish for putting such blind faith in him. It was only after the demon attack that the emotionless monotony of his life was shattered; wishing to devour the rainbow-eyed god the people whispered about, the demon disguised itself as a beautiful woman, hinging on Doma’s well-known desire for ladies. As soon as the demon was in Doma’s presence, it slaughtered all of his attendants and then announced its intention to feast on the leader.

More bemused than terrified, Doma was about to let the demon kill and eat him if only out of a detached curiosity. However, in its haste to eat Doma, the demon accidentally ripped open a curtain– letting sunlight spill into the room. Before Doma’s blessed eyes the demon burned to ashes.

Further curiosity led Doma to seek out the truth behind the sun and the thing that almost killed him. It eventually placed him on the path to the Demon Slayers, and his own desire to encounter the demons again brought him to his training, becoming a Slayer and eventually a Pillar. Discovering that killing demons gave him a semblance of feeling alongside his being with women, Doma strived to find the one kill that would give him a true rush.

This came in the form of a lonely flower-demon, whom the Slayers spoke of only in hushed whispers. Rumors of a demon who had killed her entire family and now atoned in some twisted way by caring for some child, a demon who only killed now to protect its pet. Needless to say that Doma was interested; a flower demon? Why, she’d have to be a very pretty demon indeed.

Kanae was a name Doma learned only after a long, fierce battle through the night. He had known the demon had caught his scent, and was already attempting to hide that human child she kept with her. Well, it wouldn’t do at all! It wasn’t difficult; the demon had no idea on how to fight properly whatsoever, and every flick of his fans and an intake of breath only weakened the demon further and further. It hadn’t taken long for him to bring the demon to her knees, and it was only as he had sent her head rolling into the snow that he heard a name being screamed into the wind.

It was nigh euphoric. The expression on Kanae’s face before he had taken her head was utterly sublime in its rage and grief and resignation, and Doma had felt a soaring glee at this particular hunt. It was a feeling, one that swelled to crescendos and made his blood run hot. The sun rose quickly and Doma left, satisfied. What a feeling to be alive.

Now the name of Kanae rings in Doma’s ears once again as news of Upper Moons circulate through the ranks. A demon borne through the blood of Upper Moon One at the same place where he had left Kanae to burn in the sun, a demon that demands his name with every kill and a demon that butchers any Slayer that dared wield breaths in vein to his. Doma only hums at the talk; another hunt to remember, then.
