At the mention of Ryuya, Shinazugawa Sanemi's anger flared even higher.
He stared at the demon snake in his grip and, without hesitation, swung his Nichirin Blade.
Slash!
Kaburamaru was cut cleanly in two.
"Is my blood really that delicious?" Sanemi sneered.
He grabbed the half-sized, writhing Kaburamaru—still biting into his arm—and slammed it violently onto the ground.
"Kaburamaru!!"
Seeing his companion severed and thrown aside, Iguro Obanai trembled with fury.
The last thread of restraint snapped.
"Serpent Breathing, First Form: Winding Serpent Slash!"
His curved Nichirin Blade rotated counterclockwise as he lunged forward, unleashing a swift, twisting slash like a striking python.
"Wind Breathing, Second Form: Claws-Purifying Wind!"
Sanemi retaliated instantly, releasing four green, claw-shaped wind blades.
"Thunder Breathing, First Form: Thunderclap and Flash!"
In a flash of lightning-fast movement, Kuwajima Jigoro appeared between them, his blade intercepting both attacks and forcefully stopping the clash.
"Control yourselves! This is the Master's estate!"
"Master, expel this man from the Demon Slayer Corps!"
Sanemi's voice rang out coldly.
Anyone who associated with demons deserved death. No exceptions.
"Master, surely you can see his character from his actions," Kuwajima Jigoro added sternly.
Iguro Obanai had drawn his blade and used a Breathing Technique so recklessly against a fellow Corps member. That alone violated the rules.
Combined with the earlier accusations against Kaigaku, Jigoro's impression of Obanai had sunk to rock bottom.
Kagaya Ubuyashiki remained silent, deep in thought.
Seeing the hesitation, Sanemi pressed further.
"Master, after the former Flower Hashira became a demon, the Corps established an iron rule: anyone who becomes a demon must be killed without mercy. No exceptions. Are we going to break that rule now?"
Kagaya's expression shifted.
This was no longer about personal grudges.
It was about the rules of the Demon Slayer Corps.
Without rules, there was no order.
And once rules were bent for one person, countless others would follow.
There could be no indulgence.
No exceptions.
Kaburamaru, though severed, had already begun reconnecting due to its demon physiology.
Kagaya finally spoke.
"Obanai, members of the Demon Slayer Corps are not permitted to associate with evil demons. This is absolute.
You may choose to kill this demon snake and remain within the Corps, thereby proving you have no ties to demons.
Otherwise, if you insist on keeping it, there will be no place for you here."
The words fell heavily.
Obanai's voice was strained but firm. "Master, I did not intend disrespect. The Wind Hashira acted without reason and killed my companion.
As for your request, I must refuse. I will not kill Kaburamaru.
However, I promise to restrain him and prevent him from harming others."
"Prevent it from harming others?" Sanemi scoffed. "A beast is a beast. You say you can control it? Fine. I'll give you a chance. If you can control it, I won't kill it. But if you can't, don't blame me. Is that acceptable, Master?"
Kagaya nodded silently. He already understood Sanemi's intention.
Sanemi wasted no time.
With a sharp motion, he cut his own wrist open with his Nichirin Blade.
Blood flowed freely.
He extended his bleeding arm toward Kaburamaru.
"Kaburamaru!" Obanai shouted desperately.
But the scent hit the snake immediately.
Rare blood.
Tempting beyond reason.
Kaburamaru lost all restraint and lunged forward, biting deeply into Sanemi's arm and drinking greedily.
"You beast," Sanemi sneered coldly. "You didn't disappoint me."
He looked at Kagaya, letting the evidence speak for itself.
Kagaya inhaled slowly and turned his gaze to Obanai.
"Obanai, regardless of what this snake once meant to you, it is now a demon that craves human blood. It must be slain by your own hand. This is not a matter for sentiment."
Before he could finish—
"In that case, I will leave the Demon Slayer Corps."
Obanai cut him off.
There was no need to hear the rest.
As long as Kaburamaru remained by his side, there would be no place for him within the Corps.
And he would never kill his companion.
If those were the choices—
Then he would walk away.
