When I woke up, I found myself as Nezuko Kamado!

Seeing the horrific scene before me, on the verge of annihilating my entire family, I was filled with rage!

What delicate little sister?

In this life, I hold the script in my hand, and I crush the bamboo tube in my teeth!

The game starts with awakening the Sun Breathing technique and the Transparent World. Tanjiro, step aside! Muzan, you old scoundrel, take this [Flash Dance]!

Shinobu Kocho: Something's wrong with this kid!

Yiyong: ...Water? I'd rather not learn it.

Purgatory: Hmm! What spirit this young lady possesses!

To change the tragedy and beat up the scumbag boss, in this life, I, Nezuko, will slaughter my way through the Infinity Castle!

Shenyuan Ziye's soul traveled to the world of Demon Slayer, awakened the Ice Breathing Technique, and obtained a system that allows him to level up by killing demons!

After traveling back in time for two and a half years, his parents were killed by evil spirits. Shenyuan Ziye was heartbroken and decided to join the Demon Slayer Corps. After becoming Bingzhu, he began to kill demons wantonly!

Tanjiro Kamado: Yes! Mr. Kamogen is a very powerful person!

Agatsuma Zenitsu: Kamigōnen, is work the only thing on your mind?

Inosuke Hashibira: Damn it! I can't surpass you again? Moonlit Night!

Shenyuan Ziye: Even if my body is destroyed, I will definitely kill the evil ghost!

...........

No heroine, a growing protagonist, invincible in the later stages, weak system, many battle chapters, high-energy throughout..........

A young man whose hair turned white overnight because he looked like a girl was deceived, discriminated against, excluded, disdained and despised. Fearing to experience these things again, he is unwilling to interact with people often. Even if he has friends, he only has a very small number of close friends.

His father passed away due to years of overwork, and his mother and adopted sister have always been with him and never left him.

"Brother, look, these are the cookies I made. Am I awesome?"

"Brother, can you accompany me to the park tomorrow when we have a day off?!"

"Son, Mom is going to pick up your sister from school tonight. Go buy some vegetables and come back to cook!"

However, this time it is a farewell forever!

"Do you have any other wishes? I will do my best to make them come true for you!"

"Can you take good care of my mother and my sister for me?"

"Okay, I promise!"

"Ding! A suitable host has been found, and the Demon Slayer System has begun binding! Binding completed, opening the portal to another dimension!"

"Ding, transmission successful, welcome to the world of Demon Slayer"

"Where is this place?"

[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."

Lin Guang travels through the world of Demon Slayer and awakens the Super Treasure Chest System! In Demon Slayer, slaying demons unlocks treasure chests; defeating the navy and celestial dragons unlocks treasure chests; and defeating enemies unlocks treasure chests in Naruto. Thus, Lin Guang continues to unlock treasure chests, conquering the world!

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.)

Ever since the Breathing of Fire was developed during the Warring States Period, more than 80% of the Flame Pillars have carried the name of Purgatory.

Even Rengoku Kyojuro, the last Flame Pillar of the Taisho period, gave up his own dawn for the dawn of others.

But if history diverges,

That one,

It keeps growing upwards,

The flower called "Purgatory"

Inadvertently, a fruit was born, but it was helplessly abandoned. Who can guarantee that it will sprout again as a seed in the shade and grow in a deformed form...

Or will it just be a fallen petal, transforming into nutrients to dedicate itself to the growth of future generations...

(I write simply because I feel like writing. My writing may not be good, and the updates may not be on time. After all, I am also a quasi-working person.)

What if you encounter Muzan at the start and become a demon? Before you lies the demon who doesn't eat humans, the heir to the Forest Breathing, the Pillar who strikes fear in countless demons, the honorary founder of the Butterfly House, a staunch supporter of Dorayaki, the poop-scooper of Shiba Inu Enji, the idol of the male and female members of the Demon Slayer Corps, and the trusted senior of all the Pillars: the Forest Pillar - Moriki Shinichi! [Not a system! Not a cool story! Growth-oriented! Single female protagonist! Don't read if you mind, the author is sensitive, so please don't criticize if you don't like it.]

(Pseudo-invincible + female lead Shinobu Kocho + system runs away at the start) Shimotsuki Mirai transmigrated to the present day and has spent her childhood wandering around the forges of the sword-forging village, the clanging of hammers the lullaby of her life. The blacksmiths always said this child's eyes were too still, as still as a quenched blade, unaware that the vermilion burn marks on his palms, shrouded in years of wear, concealed an astonishing power no less than that of a Nichirin Blade. When he first met Shinobu Kocho, he only felt a stinging pain in his eyes. Before seeing the girl, all his information about her came from the precious little black box he couldn't bear to part with in his previous life, but now, the person from his dreams stood before him, more vivid than any description. The girl blushed, staring at the light dancing on his fingertips, asking if he was a deity descended to earth. Kanae leaned against the door, chuckling softly, "Such a wondrous boy is hidden in the sword-forging village." Looking into the clarity in the girl's eyes, Shimotsuki Mirai suddenly wanted the sword in his hand to protect that light a little longer, just a little longer...
