As a transmigrator without any cheat codes, Tomioka Akemi was a little panicked when he found the breathing technique notes left by his ancestors. But when he thought that it was already 2022, how could there still be demons? He calmed down, until he heard about the SAO closed beta test...

"Hmm, this doesn't make sense. Why are Breathing Techniques and Sword Art Online in the same world?"

(Single female lead, Asuna, tentative storyline is Sword Art Online ---- Fairy Dance ---- Demon Slayer)

But that's alright, no one can break my defenses! This is an endless culinary journey (Enemy: ??? Culinary delights?).

Goblins absorb the spirit of heaven and earth and are not contaminated by the calamities of the mortal world. They are the supreme existence of the demon clan. They forge a treasure in their lifetime, and every time they appear, they cause bloody storms!

Ye Qingchen, a time traveler with a mysterious background, emerged from the Sin Continent holding the broken sword Mo Ran, vowing to subvert the rules of the three religions. He believed that the Tao could be reversed, and his Tao was evil!

Let’s see what my superpower is: Complete Self, Time Ability, Magnetic Field Power!

With both Time Power and Magnetic Field Power, plus something called Complete Self—am I not invincible?

What about other people’s superpowers?

World Reset, Human Superman, Dream Manipulation, Magical Girl Transformation, Isekai Transmigration, Fantasy Manifestation.

Wow… everyone’s abilities are so cool!

So, is it too much if I summon my adoptive father and brother with a Hell War God?

Evil spirit + joins Muzan + eats people + no system.

(The protagonist is very bad! Very bad! No humanity, please don't mind if you accidentally enter!)

Manami, who depended on his younger brother for survival, joined the Demon Slayer Corps and became the disciple of Yoriichi Tsugukuni, the most powerful member of the Demon Slayer Corps. However, he failed to kill Muzan during an encounter with him, and thus became a sinner of the Demon Slayer Corps. He was expelled from the Demon Slayer Corps along with his master Yoriichi Tsugukuni.

When he met Muzan again, he had two choices: become a demon and make those who hurt him pay the price, or continue to live like garbage.

Wan Mi chose the former.

Since you have expelled me, I will live my life in the most horrible way possible!

If the Demon Slayer Corps can't tolerate me, then I will become an evil demon!

Tang Yin, a person born with strange eyes, died suddenly due to not sleeping after watching Naruto. When he opened his eyes again, he came to Douluo Continent and became Tang San's brother?

Is there another hidden reason behind Ah Yin's death?

Tang Hao, old dog, everything you did was for the hundred thousand year soul ring!

Yu Xiaogang, your so-called martial soul theory is just bullshit. There are no useless martial souls, only useless soul masters? Are you talking about yourself?

He was Minato Namikaze's classmate, but the class's quietest member. He had no particular skills, and his lazy chakra prevented him from learning any ninjutsu. If nothing unexpected happened, he would become cannon fodder on the battlefield.

But—he has a cheat code! His chakra increases by 0.5% every day, and now he has one-tenth of a chakra, so the future looks promising!

I'll just focus on wielding my sword; the rest is up to the chakra!

When the Ten-Tails was born, he carried an invincible chakra and slowly raised his sword—Do you also want to dance?

Under my chakra, all ninjutsu is just flashy nonsense.

Mai Shiranui: I will definitely kill you with my own hands!

Mai Shiranui: Gu... Kill... Kill me.

Mai Shiranui: You, you, you, you are not allowed to die in the hands of others! I am the only one in the world who can kill you!

Mai Shiranui: ...It's not that I can't do it, I will definitely defeat you fairly when you get better!

Mai Shiranui: Wu Ji! You bring another woman back again, I must kill you!

...

Wu Ji, the male Sanda with toxic milk powder, the hidden BOSS of King of Fighters, the victim maker, the lifelong enemy of female fighters...

His philosophy is that the CGs that can be unlocked should be unlocked in advance, and the CGs that cannot be unlocked should be unlocked by force.

Pure love is love that comes from pure movement!

As long as you move more, hatred will turn into love, making this world full of love.

There were no victims in this world, but

after he came, victims were everywhere.

This is my first time writing a novel, so the writing is a bit watery. Don't blame me, I've gotten used to it. After about 100 chapters, the watery writing doesn't appear anymore. Sigh! The first time is always difficult.

The young man Ao Qing accidentally came to the Douluo Continent and became the son of a true dragon. He was born with the strength of a one-star Douluo Saint.

In Yunlan Sect, as soon as Ao Qing arrived, Yunshan Yunyun expressed their welcome to the master!

Medusa: "This guy is not a good person. He looks cold on the surface, but he has many tricks up his sleeve!"

Xiao Xun'er: "I was doing fine in the Xiao family, but this guy came and I said goodbye to Brother Xiao Yan."

Emperor Hun Tian: "Ao Qing has the potential to be a great emperor, I am not as good as him!"

Gu Yuan: "I wonder if Brother Ao Qing wants a beautiful woman? My daughter is so beautiful!"

Xiao Yan: "Why is the world so cruel? Where are my strange fire and my thighs?"
