Become the God of Ninjas starting from Danganronpa.

"First time trying Sun Breathing, not bad at all." Dongfang Yao flicked his longsword, shaking off the blood droplets on it, and casually remarked. But then he heard a trembling female voice beside him.

"So...so strong."

Dongfang Yao was startled and turned his head to look. He saw that the female ghost's eyes were staring straight at him. Her yellow pupils contained five parts shock, four parts relief, and one part worry.

He was stunned; it was the first time he had ever seen such a complex expression on a ghost face.

Especially since this guy had his head chopped off by me, how come he seems relieved?

Oh, right. This woman was being abused by both her husband and children. She'd probably had enough, so her nonchalant attitude towards death is understandable.

"Finally... it's all over." The female ghost murmured softly, then warned, "Be careful, that guy is... one of the Twelve Demon Moons."

He had expected that Dongfang Yao would be greatly shocked, or even horrified, upon hearing the name of his son—after all, it was the Twelve Ghost Months.

But what did she see?

"I understand, thanks for reminding me."

Dongfang Yao remained calm and relaxed, as if he had just heard the news that "lunch is rice today."

"Don't be careless..." The female ghost's head had already been half destroyed, but she was still trying to persuade Dongfang Yao.

But just then, a familiar voice rang out, making her feel as if she had fallen into an ice cave.

"Even on the verge of death, you still chose to reveal information about your son to the enemy! You are truly my good mother."

"Is it because I'm tired?" Almost reflexively, her heart skipped a beat.

But before she could react further, a large foot stomped down heavily, crushing the remaining half of her head into dust.

The one who did this was a burly demon. He was easily 1.9 meters tall, with a mouth full of sharp teeth and no other facial features, only decorative beads resembling glass beads, making him look quite anthropomorphic. If he walked down the street, he would probably terrify children.

"Demon hunter, how dare you trespass into my home and hurt my most important family members? Do you know how you want to die?" The one who said this was a thin, small boy with a full head of white hair, and the word "Descendant" was engraved in his left eye.

One of the twelve Ghost Months, the fifth of the waning crescent moon, the month of the tiring.

In terms of size, it was much smaller than the big man next to it, but the aura it exuded was far more ferocious and terrifying.

Especially when those emotionless eyes gaze upon you, it's enough to terrify even ordinary Demon Slayer Corps members, leaving them utterly demoralized and devoid of fighting spirit.

But who is Dongfang Yao? He's been extraordinary since the beginning of his school years; he's in Class Two.

Dongfang Yao did not make a move, but simply watched the scene of motherly love and filial piety, and husband and wife showing a mocking smile on his face.

"Is this what you call family? It's quite an eye-opener!" Dongfang Yao raised the Nichirin Blade in his hand. "Since you value your mother so much, then I'll send you down to reunite with her."

"You? You think you can take down a piece of trash and you're all that arrogant?" Rui sneered.

Without turning his head, he ordered, "Kill him."

"Don't come near my family!"

As soon as he finished speaking, the burly, fanged anthropomorphic demon roared, stomped his two thick legs on the ground, and charged forward like an arrow!

"Bang—"

The fist, as big as a sandbag, carried terrifying kinetic energy, causing the very air to tremble.

Faced with this terrifying attack, Dongfang Yao stood there dumbfounded, as if he had been scared out of his wits, his large face taking the brunt of the demon's violent punches.

"Hmph, utterly pathetic." Lei sneered, but his expression immediately froze, and his face darkened.

"Bang—"

The burly demon's fist pierced through Dongfang Yao's body, smashing him into the ground and creating a crater. Dongfang Yao, who had been standing there, vanished like a bubble in the sunlight.

"Breath of the Sun: Phantom Sun Rainbow"

"An illusion? No, it's an afterimage." Lei's eyes widened as he carefully searched for Dongfang Yao's trail, and he shouted a warning, "He's behind us."

The burly demon suddenly turned around and delivered a violent right hook, but unfortunately, Dongfang Yao's knife was faster.

"Breathing of the Sun - The Setting Sun Turns Around"

"laugh--"

Dongfang Yao's Nichirin Blade emitted a sun-like orange-red light, severing the demon's arm and neck as easily as a hot knife through butter.

In the blink of an eye, the tide of battle turned.

"You actually sent your own father to his death first, what a filial son you are," Dongfang Yao said with a smile, shaking the blood off his Sunset Wheel Blade at the Lower Moon Five.

"Fool, do you think you've already won? I'm not on the same level as those scum." Lei's face was gloomy, but his demeanor remained calm.

Dongfang Yao's strength exceeded his expectations, but that was all.

Next, he will let Dongfang Yao experience firsthand what the terror of the Twelve Ghost Moons is like.

Thinking this way, a dense web of spider silk appeared between his tired hands.

"Ah..." Dongfang Yao looked surprised and nodded. "I have to admit, your cat's cradle skills are definitely on a completely different level from theirs. You've been practicing diligently for a long time, haven't you, kid?"

"All you do is talk." Rui's hands instantly turned crimson as the power of his demon blood was activated.

"Blood Demon Art: Killing Eye Cage".

In the blink of an eye, the spider web between his hands, resembling a flower rope, rapidly expanded, then surrounded Dongfang Yao like a cage, leaving no room for escape.

"Be shredded into mincemeat by my spider silk." Lei squinted, already impatient to see Dongfang Yao being cut into pieces.

"This thing smells good; I might be able to enjoy it later," a thought flashed through Lei's mind.

However, this confident expression quickly crumbled.

"Breath of the Sun - Scorching Sun".

Dongfang Yao spun rapidly, his Nichirin Blade unleashing a scorching vortex like a tornado, completely annihilating all the approaching spider silk threads.

As we all know, spider silk is afraid of fire, so using the Breath of the Sun is the perfect way to deal with it.

"What?" Lei was stunned by what he saw.

It's almost unbelievable that a mere human could break his Blood Demon Art so easily.

"Hey, kid, stop spacing out." Dongfang Yao appeared beside Lei like a ghost, slashing horizontally with his Nichirin Blade.

"Breath of the Sun: Waltz"

Lei was startled and tried to dodge, but it was too late.

"laugh--"

Dongfang Yao brushed past Lei, his Nichirin Blade easily slicing across Lei's neck, sending a head covered in white hair flying into the air.

"Not bad idea." Dongfang Yao's face showed a keen interest. "You actually cut your own head off with a string beforehand. Kid, you're quick-witted!"

On the other side, Lei manipulated the silk threads to pull his flying head back and reattach it, his eyes filled with rage as he looked at Dongfang Yao.

"You...you've interfered with me time and time again, and even hurt my precious body. Unforgivable, unforgivable."

"Oh, so what are you planning to do? Show me what you've got?" Dongfang Yao held his Nichirin Blade in a fighting stance. He genuinely wanted to see his opponent's ultimate move.

After obtaining the Breath of the Sun, Dongfang Yao had a very strong feeling—he had become stronger, far stronger than before.

Even though his current ability level is still LV.1, he feels that he is not afraid of fighting those adventurers who have just entered LV.3 in close combat.

This breathing technique is perfect for him; it's as if it was tailor-made for him.

Dongfang Yao even had a strange feeling that he might be the reincarnation of Yoriichi Tsugikuni. Otherwise, how could they be so compatible?

But after careful consideration, he understood the reason. His physique had been transformed into a Sage Mode physique through the modification of Hashirama's cells and Hestia's blood. This physique naturally contained powerful Yang energy.

This powerful vitality, coupled with his all-attribute ability value being raised to S-rank, allows his body to naturally withstand the burden of Sun Breathing, thus enabling him to unleash the true power of Sun Breathing.

The surge of power gave him an urge to unleash it, so upon learning that his destination was Mount Natagumo, he rushed over without hesitation. His purpose was to use the lower moon, one of the Twelve Demon Moons, as a whetstone to test the true extent of his strength.

The good news is that he has indeed become stronger and is able to easily suppress the Lower Moon demon among the Twelve Demon Moons.

The bad news is that he's too strong. This Lower Moon demon doesn't feel any pressure at all, giving him an awkward feeling of wielding a sledgehammer but cracking a walnut.

"Kid, come on, but don't be rude." Dongfang Yao concentrated, focused intently, and prepared to take the opponent's ultimate move head-on.

"Blood Demon Art - Secret Technique - Scrolling Rotation." Rui was completely enraged by Dongfang Yao's contemptuous attitude and unleashed his strongest Blood Demon Art with all his might.

In an instant, a burst of blood-red light erupted between his exhausted palms, with countless crimson threads crisscrossing within them.

Then, these blood-red threads suddenly swelled up, rushing towards Dongfang Yao like thousands of venomous snakes.

The silk thread is as hard as the strongest steel, and its sharpness far surpasses that of ordinary swords. Everything it touches is cleaved in two.

Whether it's leaves, trees, or rocks, they are as fragile as paper in the face of these threads.

"This is it, this is it!"

Faced with this move, a strong sense of crisis made Dongfang Yao feel as if his blood was on fire.

Then, he moved.

The Nichirin Blade in his hand emitted an orange-red light like a sun halo, drawing a winding and agile arc in the air, like a swimming dragon.

"Breath of the Sun - Dragon of the Sun Halo."

Faced with these scorching hot strikes, even the tough spider silk enhanced by Blood Demon Magic became utterly vulnerable.

In the blink of an eye, the dragon with the halo around the sun grew larger and larger in Lei's pupils, until it filled his entire field of vision.

"laugh--"

My head was spinning from exhaustion again. But this time, there was no deliberate attempt to save myself; it was a complete and utter severing of all hope.

"Are you... a human or a ghost?"

Exhausted, his head fell to the ground, his eyes fixed on Dongfang Yao, unable to believe that he had been defeated so easily.

He's the fifth Lower Moon, with the potential to rise to the Upper Moon. How could he lose here?

"Little friend, don't be so bossy when you play house in your next life," Dongfang Yao said without answering his question, then turned and left.

All that remains is the weariness of dying with eyes wide open in dismay.

......

"Hoo~ Ha~ Hoo~ Ha~"

On the hillside, several slender figures were running wildly.

They are Lei's "family," known as "younger sister," "older sister," and "younger brother."

For decades, or even longer, they have been forced to stay here, playing that twisted game of make-believe with their boss to satisfy his warped view of family.

Although they may suffer various forms of violence, both hot and cold, at least they won't be targeted and have their heads chopped off by some ghost hunter.

But now, I'm exhausted!

The family that had always protected them, the powerful Twelve Demon Moons, has lost the Lower Moon Five!

In the instant they died from exhaustion, they learned of this matter through an unseen connection in their blood.

Then, panic erupted like a volcano.

Even a powerful being like Lei can be killed, so what will happen to these small fry?

Run! We must run! Run as far as possible.

No matter what, stay far away from that devil.

These guys are all ghosts, with physical strength far exceeding that of ordinary people. They quickly crossed the vast mountains and forests and were about to leave this dangerous place.

Freedom seems to be within reach.

"Quick, we'll be safe soon!" the eldest sister exclaimed excitedly. The others also perked up and quickened their pace.

But just then, several figures appeared in front of them: a half-naked man wearing a boar headgear, a red-haired, red-eyed boy with a sun-shaped earring, and a timid boy with blond hair and golden eyebrows.

This naturally refers to Inosuke, Tanjiro, and Zenitsu, who went into the mountains to search for the other Demon Slayer members.

While Dongfang Yao and Rui were fighting, they were also busy gathering the injured Demon Slayer Corps members together, keeping themselves very busy.

But just then, the ghost broke in, and they immediately tensed up.

"Ah, it's demons!" Zenitsu exclaimed. "And why are there so many? It's terrifying."

Zenitsu's performance immediately put the demons at ease.

"What? Just a bunch of rookie demon hunters." The leader chuckled, licking her lips. "Perfect, we had some food on the way. Let's capture them."

She was the strongest among them, besides Rui and "Father". At her command, her brothers and sisters immediately sprang into action, charging towards Tanjiro and his companions.

They thought the process would be as simple as a lion hunting a rabbit, and that they would be the predators, taking whatever they wanted from above.

Especially after seeing the timid blond-haired, blond-browed boy suddenly collapse unconscious, he became even more convinced of this.

However...

"Water Breathing - First Form - Water Surface Slash".

"Beast Breathing - Second Fang - Slash".

The two rookies acted decisively, their swift slashes leaving the two ghosts no time to dodge, and their heads were severed.

"What?!" The older sister exclaimed in surprise, instinctively summoning countless threads to grab Zenitsu.

Those two guys are troublesome; she needs to find a hostage, or she'll be finished here.

pity...

"Thunder Breathing - First Form: Thunderclap Flash".

A flash of lightning streaked across her face, and she felt a sharp pain in her neck before her consciousness vanished into eternal darkness.
