[Demon Slayer + System + Isakuza + Single Female Lead + Exciting Battles]

Fan Ma Lingyun unexpectedly transmigrated to the Demon Slayer world, was taken in by the Kamado family, and was bound to the "Heaven Rewards Diligence" system, which allows him to infinitely increase his physical strength as long as he trains hard!

To prevent the tragedy of the Kamado family, Hanma Ryoun began arduous training, constantly climbing towards the throne of the strongest.

Just as Muzan was about to attack the Kamado family, Hanma Ryoun intervened in time, defeating Muzan in one blow and posing three soul-searching questions.

"What's so interesting about it? What's so funny about it? What do you take your life for?"

Muzan's expression instantly cracked upon hearing this!

He then joined the Demon Slayer Corps and began his journey to slay demons.

Fan Ma Lingyun: "Huh? What's a breathing technique? I'm all about raw power! There's no mechanics, it's all about numbers!"

He was transported to the Naruto world by accident and discovered that he had gained the ability to absorb energy. So he went further and further down the path of searching for and absorbing others.

[A random female protagonist + a changing doll + a loser female protagonist + my little sister + ...]

The moment I close my eyes and open them again, a non-existent memory suddenly appears in my mind.

Rebirth or reincarnation?

Kazama Tetsuya doesn't want to think about those things right now. After his parents' divorce, he became self-destructive and had no source of income.

And those works that popped into my memory are completely absent in this world!

Kazama Tetsuya went completely mad, determined to use the works from his memories to make money and support his family, resulting in: "Saekano: How to Raise a Boring Girlfriend", "My Youth Romantic Comedy Is Wrong As Expected"...

As a result, just three days after submitting the first volume of the light novel, there was a sudden knock on the door of Tetsuya Kazama's house.

Are editors these days so dedicated? They're actually going door-to-door to sign contracts?

...

Reincarnated as the final boss hidden in the far north, the million-year-old soul beast, the Xuan Shuang Ice Phoenix, Chu Han took the art of survival to its extreme, to the point that even the God Realm was almost forgetting about him.

The Douluo God Realm persecutes soul beasts too severely. Even if a soul beast has cultivated for a million years, it can become a god at any time. However, Chu Han has always suppressed his cultivation level.

His long and arduous life of hiding and fleeing finally came to an end when he received the inheritance from the Chinese phoenix.

He abandoned everything, transformed himself, and started anew, but was entangled with the Snow Empress and the Ice Empress, who willingly became his spirits.

Having just left the far north, he was forcibly taken to Tianshui Academy by a woman, becoming the only male student in the academy's history.

Qian Renxue: "Such an extraordinary talent should be put to my use."

Zhu Zhuqing: "If only I were as strong as him..."

Tang San broke down in his guard: "How can the difference between people be so huge!"

In the Star Dou Great Forest, Silver Dragon King Gu Yuena falls head over heels for him; in the Heaven Dou Imperial Palace, Qian Renxue confesses her love several times; Zhu Zhuqing wants to ask him for advice on how to become stronger; Xiao Wu is ashamed of betraying her soul beast clan…

On the day Chu Han became a god, the Asura God, who had been waiting for a long time with the Asura Divine Sword in hand, exclaimed in disbelief, "Impossible! How can a soul beast become a god without being bound by the divine realm! And how come your divine power is more advanced than my Asura divine power..."

Ye Hao has transmigrated!

However, upon discovering that he had become the Sea Heart Flame in the hands of Han Feng, this traitorous disciple, Ye Hao felt a wave of dizziness and a sense of utter ruin.

Fortunately, there's always a way out, and the golden finger, a standard feature for transmigrators, is activated...

"Hmm... Let's set a small goal first: break through to the Dou Di realm within ten years. Isn't that a bit much?"

Tennoji Kaede enrolled in Advanced Nurturing High School and successfully awakened the Gray House Karma System!

The more you are tainted by the 'cause', the more 'effect' he will give back!

"Gray House, add some points!"

Afterwards, Tennoji Kaede was assigned to Class C and formed a partnership with Ryuen Sho.

From this moment on, the unbeatable King Class C was officially born!

......

"Ayanokoji Kiyotaka? The White House is just a masterpiece, but can you beat my Gray House's supreme martial arts?"

"Yamachi Haruki? The Black Room is the supreme masterpiece, but I, Tennoji Kaede, am willing to acknowledge you as the strongest underground!"

"Longyuan, please believe me, I have absolutely no intention of using you as a tool!"

"Besides my little angel Hiyori, are there no decent girls in the actual class?"

......

Time flies, and three years later, it's graduation time.

The ultimate strategy that Tennoji Kaede decided upon entering the university has been achieved!

He ultimately became a legend of practical education and high moral character...

Reborn into Japan, I made tokusatsu films, plagiarized articles, and games, thinking I could live a carefree life. However, on the first day of Sword Art Online's huge success, news of Kayaba Akihiko's imprisonment completely disrupted my life. Shortly after Oregairu's release, a car accident occurred in front of Soubu High School. Three days after Date A Live's release, a spacequake alarm sounded in Tengu City. So, plagiarism is the limit! So I started drawing manga! But just as My Hero Academia, JoJo's Bizarre Adventure, and One-Punch Man were selling like hotcakes, a glowing baby appeared in a hospital, an astronomer discovered a meteorite named Kars, and a bald man appeared on the street... To draw Golden Wind, I went on a trip to Sardinia, Italy, only to be attacked by a rebellious god at the start, followed by a relentless pursuit. "Being a plagiarist is really too hard."

He transmigrates into the world of Kuroko's Basketball, carrying a skill proficiency panel, only to find himself in the world of Prince of Tennis, Akutsu Jin. This time, he will not waste his body's talent and is determined to reach the top.

"Genius? Miracle? Chosen by God? Ha, those are merely the threshold to seeing me." After saying this, Akutsu slowly raised his head, his eyes flashing with electricity, and several phantoms in different poses appeared around him.

Lin Mu unexpectedly transmigrated to Douluo Continent and awakened the Nawa summoning weapon spirit. After ten years of cultivation, he reached level 46 Soul Master and accidentally bumped into Tang San, who was preparing to enroll in school. Just then, the golden finger he had been waiting for for sixteen years finally arrived. It was a very simple interface. [Main Quest: Take Tang San as your disciple, reshape his worldview.
