[Demon Slayer] + [Torture] + [System] + [Invincibility] + [Substitute Player]

"After being stabbed ninety thousand times, can I finally die?"

Doma looked up at that handsome yet empty face, a morbid expectation rising in his eyes.

Xuan Lin simply shook his head slowly.

"Can this boiling oil really wash away my sins?"

Kokushibo stared at the boiling oil, his voice trembling slightly.

Xuan Lin remained silent.

"You mean... after I'm burned away by this karmic fire, I'll be able to see Lianxue again?"

Akaza stared at the leaping flames, a rare glimmer of hope appearing in his usually arrogant eyes.

Xuan Lin nodded slightly.

"I've been scorched by this blazing sun nine thousand times!"

Kibutsuji Muzan roared in the sunlight, his voice distorted by extreme pain, "How long are you going to torture me?!"

Xuan Lin finally spoke, his voice calm and devoid of emotion: "Until the souls of the dead whom you wantonly slaughtered in this world can truly rest in peace."

Xuan Lin, 30 years old, grew up in an orphanage and has spent half his life in solitude.

He accidentally slipped and fell while taking a piss, which led him to be transported to the Demon Slayer world overrun by evil spirits.

When the survival rules of society learned over thirty years crumble into dust in this cruel world, when the animated scenes once followed on the screen turn into bloody reality.

He had no choice but to grip the blade tightly in his hand.

Their evil will not cease with death; a "divine punishment" created specifically to end them has arrived.

All sins will eventually be brought to justice.

[Funina (herself) lost her memory of playing the role of god for about 200 years + played the role of god in another world + had the eyes of God + traveled to the time when Yoriichi Tsugakuin was not yet born]

After 500 years of acting, the gods’ role has come to an end.

The former "Water Goddess" Funina, no longer worried about her lies being exposed, has been immersed in the joy of shopping and has no place to stay at home.

The original god traveler (player) generously gave a space backpack, which was filled with a lot of delicious food, but the most important thing was that it finally solved the problem of having nowhere to put things.

That night, Funina tripped over something and hit the corner of the table, falling and being swallowed by a hole.

"Main system, I... accidentally swallowed the original god character into the demon slayer interface..."

"Can I still go back?"

"Not yet...."

"Activate Plan B and ensure she's alive until you're able to teleport her back."

“…Yes, yes!”

The sea breeze caused the water to rise and fall. A lady in gorgeous clothes appeared on the sea surface, which was supposed to be deserted. She seemed to have become the ruler of the sea...

Finina woke up and found herself standing on the sea! Shouldn't she be in the auditorium of the Picclet Opera House, watching Villette's trial? Shouldn't she be playing the role of the water goddess?

Where is this?! No no no…why am I standing on the sea?!

God's Eye! How could I have God's Eye!

Finina was about to throw it away, but then she remembered that the ability to stand on the sea might be related to the Eye of God...

"No, I can't die... I still want to play the role of God..."

[Crossover] + [No CP] + [Plot-oriented] + [Not invincible]

The protagonist has the same appearance and Sun Breathing as Yoriichi Tsugakuni, but his strength is not as strong as Yoriichi Tsugakuni, and his personality is exactly the opposite.

Gu Xuan: I can’t protect anyone I want to protect. I am a worthless man.

Everyone in the Demon Slayer Corps: It was Mr. Guxuan who led us to kill Muzan Kibutsuji, and it was also Mr. Guxuan who saved us when we were in crisis.

To protect his childhood sweetheart, the naturally insightful Shihouin Suqiu resolutely chose to join the Demon Slayer Corps and become their hidden ace, the Shadow Pillar. All tragic endings will be changed. No one will be hurt or cry anymore, because I'm here. "Muzan, didn't you say that those you hurt were merely experiencing natural disasters? I am your natural disaster."

On the night of Kiritsugu's death, Shirou fell asleep and woke up to a new world.

There are ghosts here, and there are swordsmen who kill ghosts.

From now on, partners of justice are no longer a borrowed slogan!

But it is a creed that you carry out throughout your life!

Ghost King, give me your life!

Infinite Holy Grail War?

Run through every one of them!

What is it like to travel through time and space and become the son of Wuzhan Wuzhan?

Kenjin did it, traveled to the world of Demon Slayer, and became Muzan's son. It seems that his biological father is still Tsugukuni Yoriichi.

Jianren: "Mother...I want...to drink milk!"

Wuzan: "Little thing, dare to disobey my orders again!"

"I'll let you experience what hell is like."

When Ji Guoyuan saw the same pattern on Jianren's forehead, he was stunned.

"Uh...why does this kid look exactly like me when I was younger?"

Tamayo stroked her bulging belly.

"How can you... be Muzan's child ಥ_ಥ"

Duji's eyes were filled with tears.

"Young Master...I also want a child."

Having a son and a daughter, so happy

My wife, my children, my warm bed, my name is Jianren

A boy named Uchiha Mei lost his parents to demons when he was ten years old. He met the Flame Pillar, Rengoku Makijuro, and became his disciple, possessing extraordinary talent. He formed a bond with the Flower Pillar, Kocho Kanae, becoming Tanjiro's teacher. He arrived in time to fight Child Demon when Kanae was attacked. He instinctively killed Child Demon, but Kanae was seriously injured. To ensure Kanae's safety, he inadvertently allowed Child Demon to escape. He later became the Fiend Pillar.

After becoming Douma, why did he still follow the same old path as in the comics?

Oh no, this won't do!

So Douma decided to become a heartthrob.

Ghosts & humans: (╬▼皿▼)

A young man from the modern era travels to the Demon Slayer world and becomes the descendant of Tsugakuin Yoriichi – Tsugakuin Najo. The protagonist is born with markings and natural transparency. There are two female protagonists (guess who they are): Muzan: "Don't come over here!" Kokushibo: "Come on, you will finish Yoriichi's unfinished duel!" Sango: "The ultimate battle!" (Slightly altered plot) (This book is not a cool novel; just having markings and transparency doesn't mean you can easily kill an Upper Rank! It's a coming-of-age novel.)
