Anime Crossover: I, the Shadow King, slaughter my way through DanMachi!

[Note: This is a special single-player instance, accessible only to the key user.]

[Dungeon Features: Enemy strength will adapt to the challenger's ability, so it's best to enter as early as possible.]

The time flow in the instance is different from that in the outside world.

No matter how long you stay inside the instance, time will not pass in the outside world.

[Recommended level to unlock this dungeon: LV10]

"A Demon Slayer dungeon?"

Ying Ping stared at the crimson key in his hand, engraved with flame patterns, his pupils burning slightly.

It wasn't out of fear, but because of an extremely intense feeling of excitement.

As a time traveler, he naturally knew what this meant, and he had also seen the theatrical film—

The Infinite Train shrouded in nightmares, and the formidable Upper Moon Three, one of the Twelve Demon Moons, who will appear at the end...

The thought of facing such an enemy made Ying Ping's blood boil.

"Master? This key wouldn't be...?"

Kokoro covered her mouth, looking at Yingping with concern.

She had been to the Sekiro instance world with Yingping before, so subconsciously she believed that places that could be entered with this key were extremely dangerous.

However, danger often coexists with opportunity.

“That’s right, this is yet another key that can enter other worlds.”

Yingping turned around and gently stroked Kokoro's cheek.

He said affectionately, "But I'm sorry, I can only go alone this time, because it's a necessary condition to open the key."

"So that's it..."

A hint of unease flashed in Kokkoro's eyes, but she quickly smiled firmly again: "I believe in Master's current strength. You will surely return victorious. We will all be here... praying for you."

She knew that she couldn't change Ying Ping's mind on her own.

Yingping gently ruffled her long, silvery-white hair again: "Yes, thank you, Kokoro. I'll be back soon."

After locking the door from the inside of the guest room, Yingping took a deep breath.

He summoned back all the shadow soldiers who were killing in the dungeon, and they all merged into the shadow beneath his feet.

Then, the crimson key transformed into flowing flames in Ying Ping's hand, tearing a blood-red vortex in the air.

The red portal reappeared.

[Enter Demon Slayer: Kimetsu no Yaiba the Movie: Mugen Train now?]

【whether】

Without hesitation, Ying Ping stepped into the vortex.

In the midst of the dizzying sensation, he seemed to hear the roar of a steam locomotive and smell the aroma of burning coal—

[Instance quest triggered]

Main objective: Protect all passengers on the train until dawn.

Side objective: Defeat Akaza, the Upper Moon Three of the Twelve Demon Moons.

[Reward: Unknown]

[If you can kill Akaza by shining sunlight on him, you will also receive a special kill reward.]

You can only return to the original world after completing the main quest or failing the main quest.

"Very good, very interesting."

Yingping cracked his knuckles, a dangerous smile playing on his lips: "Let me see if the Upper Moon, with its enhanced adaptability... can force me to unleash my full power!"

The Infinite Train had derailed and was now lying haphazardly on the roadside.

Tanjiro Kamado suffered a severe abdominal wound, and blood flowed continuously.

He was panting heavily and had to lie on the ground to stop the bleeding using the breathing technique taught to him by Flame Pillar Rengoku Kyojuro.

"Great, the bleeding has stopped successfully."

"With diligent practice of breathing techniques, one can achieve what ordinary people cannot."

"While it may not be possible to do everything, it will certainly make you stronger than you were yesterday."

Kyojuro Rengoku's face wore a warm, sun-like smile, which inspired Tanjiro.

"Yes, thank you very much, Mr. Purgatory."

Tanjiro felt a warmth in his heart, and a relaxed expression appeared on his face.

But at that moment, a powerful, suffocating ghostly aura suddenly appeared.

"boom!"

A loud bang ripped through the night sky, and the ground shook violently.

Tanjiro looked up in horror and saw a figure fall from the sky and crash heavily onto the overturned train wreckage.

Kyojuro Rengoku immediately became alert, crouching down with his sword drawn, his eyes fixed on the figure in the dust ahead.

Amidst the grating sound of metal twisting, the figure slowly straightened up.

Under the moonlight, a demon with short pink hair and blue tattoos covering its body was grinning wildly.

The words "Upper Moon" and "Three" were clearly visible in his golden pupils.

"That's Upper Moon Three!?"

"Why are you here now!?"

Tanjiro's pupils contracted sharply, and cold sweat instantly soaked his back.

He instinctively tried to get up, but the wound in his abdomen prevented him from moving.

"Do not move!"

"Your wound will reopen!"

Kyojuro Rengoku immediately stepped in front of Tanjiro, his Nichirin Blade already drawn, the flame-patterned haori fluttering in the night wind.

Akaza's gaze passed over Rengoku and stared straight at Tanjiro, where he saw the pair of earrings that Muzan, the Demon King, had mentioned.

This is the boy that Master Muzan spoke of.

"call out!"

The next moment, Akaza's figure suddenly disappeared from the spot.

He suddenly swung his fist and lunged straight at Tanjiro, who was lying on the ground!

Kyojuro Rengoku's pupils contracted sharply: "So fast!"

"Breath of Flames: Unleashed Flame Vortex!"

In an instant, Purgatory swung his sword, and blazing flames formed a spiral barrier around him, directly blocking Akaza's punch.

However-

"Oh, it's the Flame Pillar."

Akaza's voice came from behind, and Rengoku felt a chill run down his spine.

At the last second, he managed to turn to the side, but Akaza's fist still grazed his shoulder, drawing a spray of blood.

"Mr. Purgatory!"

Tanjiro shouted in despair.

Akaza retreated a considerable distance, shook the blood off his hands, and looked disappointed: "Is this all the Flame Pillar is capable of? How disappointing."

Kyojuro Rengoku knelt on one knee, the wound on his shoulder so deep that the bone was visible.

But he still gripped his Nichirin Blade tightly, his eyes burning with indomitable fighting spirit: "As long as I stand, I will never let you hurt anyone!"

"Hahaha! What do you mean? That's more like it!"

Akaza laughed excitedly and assumed a fighting stance: "I haven't killed a Flame Pillar yet, you will be the first!"

Just as the two sides were about to clash again, an unprecedented sense of oppression suddenly enveloped the entire arena.

Akaza's smile froze, and he abruptly turned to look at the night sky: "What...is that!?"

In the pitch-black night sky, a figure plummeted from the sky like lightning!

The black trench coat fluttered in the wind, and the face under the hood was not clearly visible.

Only those scarlet eyes gleamed with an eerie light in the darkness.

Yingping stood directly in the middle of Akaza and Rengoku Kyojuro's battle, instantly maximizing his cool factor.

"who are you!"

Akaza's golden pupils contracted sharply, and for the first time, her voice trembled.

He could feel that the fighting spirit emanating from the man who had suddenly appeared in front of him was so tangible that even the air itself was distorting!

“I am...Shadow.”

"Hidden in the darkness, hunting those who dwell in darkness."

Ying Ping took the Hestia Sword in his hand and said coldly.

"Shrimp trembling?"

Akaza's golden pupils narrowed slightly, but a smile of excitement curved at the corners of his mouth: "A name I've never heard of before."

Both Kyojuro Rengoku and Tanjiro wore expressions of confusion.

This mysterious black-clad swordsman who suddenly appeared was neither a member of the Demon Slayer Corps nor did he possess any demonic aura.

"I am Akaza, the Upper Moon Three."

Akaza proudly announced his name, his blue tattoo gleaming eerily against his pale skin.

He stared intently at Ying Ping, his eyes gleaming with fanaticism: "You must be... a pillar too, right?"

"I knew it at a glance—"

Akaza opened his arms and took a deep, blissful breath: "That powerful fighting spirit has been tempered and refined, and it's already close to the supreme realm!"

He suddenly smiled sincerely: "So... I have a really good suggestion for you, how about... becoming a ghost?"

"Of course not."

Ying Ping chuckled lightly, and twirled the Hestia Sword in his hand with a beautiful flourish.

"Akaza, let me tell you why you can only be a mere Upper Moon Three."

"Because you are a demon."

This unexpected answer stunned everyone present.

"The body of the evil spirit is not complete."

Ying Ping explained with feigned contempt, "You are afraid of sunlight and cannot eat the food that humans enjoy. You hide like rats in the gutter. You are defective products of human evolution failure."

Upon hearing this, Akaza's face instantly darkened, and his fists clenched tightly together.

Yingping's words struck a nerve with him and insulted the official.

"Become human again, Akaza."

Yingping also extended his hand, feigning sincerity: "In this way, you will be able to defeat the sunlight immediately."

"Whether it's day or night, you can stand tall and proud in the sunlight and in front of crowds, and then continue to cultivate yourself and become stronger!"

"The meaning of human life lies not in its length, but in living uprightly and contributing to others."
