[Rui] also known as "Lower Moon Five: Spider Demon"....
Among all six Lower Moon demons, [Rui] was the only one that Muzan took special interest in, allowing him to develop a "family" and considered him a "son".
People always feel sympathy for those who share their tragic experiences,
[Rui] and [Muzan] both had fragile lives; one originally had [cancer] and the other [leukemia], both once bedridden, unable to live or care for themselves like normal people... Perhaps it was because of this "shared" past that Muzan sought out [Rui], transformed him into a demon, granting him a new life while also indirectly severing his only ties...
Unable to accept the fact that their son had become a demon, forced to live by consuming humans... compelled Rui to kill his parents.
That day, his father intended to end his life with his own hands, taking on the sin of cannibalism, to die alongside him...
That day, his mother lay in a pool of blood, apologizing to him in her dying moments for not giving him a healthy body...
[Rui], in his daze, realized just how important family was to him, so... the demons of Spider Mountain, under his control, were forced to play house with him....
Unfortunately, some things, once done, can never be undone!
Roy killed the "Spider Sister" with one strike, the "Spider Little Sister" with two, sent off [Rui]'s parents with three and four strikes, and pierced his "Elder Brother"'s heart with a fifth... Looking back, he suddenly discovered... the main body [Rui] was nowhere to be seen.
[Hint: "Life Energy" +11+12+11+13+15...]
[Demon Codex... recorded...]
[Spider Demon Family: D-Class Creature]
[Constitution: 187→321]
[Innate Blood Demon Art... [Spider Silk Manipulation]... [Spider Venom]... [Skin Hardening]... extracted...]
Note One, [Spider Silk Manipulation]: The host can manipulate others to follow orders by forming "Nen Line" into a "Spider Silk" shape.
Note Two, [Spider Venom]: The host can inject toxins into "Nen" to "spiderify" others.
Note Three, [Skin Hardening]: The host can concentrate "Nen" on the skin to harden it, enhancing defense.
The panel's notification sound chimed as streams of information poured into Roy's mind... The youth pondered for a while, realizing that [Spider Silk Manipulation] and [Skin Hardening] were essentially "Thought Form Change" and [Ken]...
Opening the panel again confirmed it belonged to [Thought Form Change section +10]...
Though [Spider Venom] proved quite effective in "interrogation under torture" or "tormenting people", and in sneakily "plotting against foes".
Roy flicked his thumb against his middle finger, ejecting a "Nen Line" with a "whoosh", attaching [Spider Venom] to it, and hitting a tall cypress tree nearby, visible to the naked eye...
The tree was corroded by the potent venom, white spots appeared on the bark, and with a gust of wind, branches and leaves fell, withering away in an instant!
Alongside it, an "Eye Demon" lurking in the tree let out a scream of "ah~", falling to the ground, its body instantly spiderified, finally exploding with a "boom"!
Green blood splattered, spreading to Roy's feet.
The youth, expressionless, remarked, "Does it look good?"
The sun and mountains dangled from his ear as he glanced nonchalantly, looking towards a distant direction...
Infinity Castle.
Amidst a pool of blood, dressed as an old brothel keeper, Kibutsuji Muzan personally dispatched four Lower Moons: "Two", "Three", "Four", and "Six", and supported "Lower Moon One: Nightmare" to successfully evolve... sharply sensing [Rui]'s anomaly...
The "Spider Young Man" buried his head, shuddering shoulders, trying hard to maintain composure before his "Master", his blood-red eyes surrounded by bulging veins, immediately knowing that his nest and family had been wiped out!
"It was that swordsman..." "Eye Demon" was killed; before death, Muzan saw those hanafuda earrings again, and the youth's indifferent gaze stabbed into his heart like a knife, causing uncontrollable cold sweat.
He maintained a dark expression, striving to stay calm, patting him on the shoulder, saying: "Angry? Go... together with Nightmare, kill that swordsman for me."
"Yes." [Nightmare] [Rui] knelt on the ground, and upon a gentle pluck of the biwa by the flutist, they were sent outside Infinity Castle.
After they left, Kibutsuji Muzan stood there in silence for a long time, softly calling: "Akaza, you know what to do."
"Kill!"
A youth with short purple-red hair, wearing a white shirt and green belt, red hair and gold eyes, dressed entirely in martial artist attire, knelt on one knee, merely uttering a single word. With a gentle pluck of the biwa by the flutist, a passage opened, and in a flash, he disappeared, chasing after the departing [Nightmare] [Rui] from Infinity Castle.
"Deploying one Upper Moon, two Lower Moons... should be enough....."
Soft murmurs reverberated in the directionless Infinity Castle... The flutist immediately closed Infinity Castle... Kibutsuji Muzan covered his chest, finally feeling a sense of safety....
"Caw~ Kamado Eiichiro, Tomioka Giyu sent a message..."
"Caw~ Kamado Eiichiro, Tomioka Giyu sent a message..."
Outside Spider Mountain,
Roy, having just cleared a plethora of Spider Demons, scavenging a wave of "Life Energy" and preparing to add points, suddenly heard the cry of a crow, extended his arm, letting the crow drop a letter onto his arm, instantly recognizing it as...
Indeed, it was the "messenger" Kasugai Crow belonging to his brother Giyu.
The youth faintly guessed something, opened the letter to read... On the small paper, a concise message, in Tomioka Giyu's style...
"Eiichiro, the Lord summons, the Hashira Alliance Meeting will convene posthaste, please attend, to discuss..."
"The movement of the Upper Moons!"
The storm is coming... Roy keenly sensed a killing intent!
Rolling the paper, he imbued it with a trace of [blazing truth], burning it to ashes, raised his eyes to glance at the sky... Nightfall withdraws, the red sun will rise, a corner of the sky dyed with red clouds, perfect for sending off demons!
He softly said, "Yes."
"Caw~" the Kasugai Crow, having received a response, spread its wings, flew away, leaving a black feather drifting down to land on the youth.
He supported himself with the Shallow Strike, gazing at the rising sun, for a moment... departing from the world of the Demon Slayer, and returning to the world of the Hunter.
The familiar sensation of falling hit him...
Hunter World, Republic of Padokea, Zoldyck Family Residence, Kukuroo Mountain.
After a two-hour afternoon nap, the effect was immediate... When Roy opened his eyes, rolling out of bed, he felt refreshed, his depleted nen nearly half restored.
He did not forget his grandfather Zeno's advice, taking advantage of the afternoon to pay respects to Jager, he pulled open a drawer, took out that "Records of the West Continent" ready to study it, the first sentence on the title page left him stunned...
"We are merely cockroaches despised by the gods, inedible and disgusting to look at, better to banish to the lower realm"
