[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?

...

When Yi Chen stepped into the world of "Godslayer", a new ironclad rule was added to the world.

"In the magic world, I'm the one in charge. Who agrees? Who disagrees?"

The Silver Hand of the Sword King is nothing more than a slightly thicker Qilin arm, and the wolf kept by the Norse Marquis is actually no different from a husky found on the street.

A disobedient god? He'll smash you with an elbow!

The Last King? He'll elbow the other gods first, then you.

But before that, the white-haired loli named Athena came over and bowed her head, saying, "I have some delicious food here."

Yi Chen: "Sigh, whose card should I choose today?"

Main story: Godslayer (Completed) — Re:Zero -Starting Life in Another World- (Ongoing) —

[Not a wish-fulfillment novel + Collapsed new world + Happy ending + Cinematic viewing experience + Multiple female leads (Kiana is the main heroine) + Only the protagonist has a substitute]

Thanks for the invitation. I just woke up and found myself transmigrated to the world of Honkai Impact 3rd, but it's a world that hasn't collapsed yet, and my identity is the apprentice of the God of Cookery.

Well, anyway, it's good that they're alright.

But just when Dongfang Yan thought he would grow old with Kiana, he was suddenly pulled into the viewing experience along with the main characters of Honkai Impact 3.

And the protagonist in the movie is actually himself!

Is this something that happened in another world?

Wait! Why is that version of myself starting to glow?

His cheat is a substitute!

What Stand could it be? Star Platinum, The World, or Crazy Diamond?

But when the stand-in appeared on the screen, Dongfang Yan was dumbfounded.

"What the hell is this pearl jam?!"

If you were transported to the world of Mingchao and unexpectedly gained alchemy from another game as a cheat code, would you choose to drift with the tide and watch the rise and fall of civilizations? Or would you choose to join the wanderers and save this world struggling in despair?

Faced with this choice, most people would probably choose to save the world with the Wanderer. After all, the Wanderer has no shortage of beautiful girls around him. But what if the Wanderer breaks your multi-million dollar alchemical golem right from the start? Chen Fan says: I don't care if you're the emperor of Jinzhou or the leader of Black Coast, if you break my stuff, you have to pay for it!

So, in order to collect her debts, Chen Fan chose to drift with the drifters for a while. However, after a while, Chen Fan's smile vanished: "Hey sis, I didn't ask you to pay it back like this!"

In short, faced with such a disastrous start, what changes will Chen Fan make to the world?

[2.3 million words completed] Mingyu, possessing the power to rewind time and traveling through a world of collapse, embarks on a journey of endless reincarnation and salvation. "After entering Saint Freya, you made many trustworthy friends." "You attempted to save many girls who should have died young, and in return, received their gifts." "A Certain Scientific Railgun, Mokopotmo, Infinite Space..." "Facing Kevin, you began to chant, summoning a barrier constructed entirely of the Holy Judge of Heavenly Fire." "Facing Alicia, you promised her that humanity would defeat the collapse, but without sacrificing everything." "Facing the Cocoon of the End, you gradually understood everything about that man. You knew you could defeat it, but it would be a long process, lasting eternity." "Traveling through the endless future, you finally transformed this imperfect world into a place of hope."

[No serious training, all about technology.] Qin Xuan, a scientific researcher in his previous life, traveled to the Fuyuki Three Houses, and from then on, the world line gradually collapsed... "The Twenty-Seventh Ancestor of the Dead Apostles? Try my Five Elements Fusion Array!" "The Clock Tower at the Center of the Western Magic World? Mathers and Aleister don't even take it seriously!" "Ainsworth wants to rewrite the planet's mythology? Has he asked the old man Chaos next to me?" "The Templar Church launched the Third World War? Mobius and Velvet flipped the table and switched to the scientific phase!" "The next world line is in a crisis of humanity? You've come just in time to see what the Fourth Calamity is!" "The Beast of Disaster? It's not even half as good as my final trial as a human!"... Qin Xuan, carrying the Cave Heaven World Tree on his back and holding Mooncell in his hand, faced the kings of the Lostbelts, the Predator Planets, the Blue Glitter Galaxy, and powerful enemies from the multiverse. "Who else refuses to surrender?"

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Even better news is that you can travel to the world of anime by train.

What pioneering and interesting things did you do after becoming a navigator?

She was paired with Kirito.

Adopting Lolis from All Over the World

Discussing the relationship between monarch and subjects with a famous queen

The birth of the king was celebrated with a cannon salute; God was lured onto a train; and Shiori almost fell in love with him.

Do these count?

Worlds experienced: Sword Art Online, Black Bullet, Akame ga Kill!, Date A Live, High School DxD, Guilty Crown, Academy Battle, Accel World...

(P.S.: The world-building is mostly from older anime series, with fewer newer ones.)

(Limited-time bounty now open, see details) The deceased Ren Wei has accepted a commission from the World Will. Due to an invasion by outsiders, he must protect the world of comics spawned by the World Will. The popular heroines have become the targets of the Lord Gods and the Reincarnators!

Witch's Journey + Undead Civil War with Ainz Ooal Gown + Re:Zero + Fate + A Certain Magical Index + One-Punch Man. I love Misaka Mikoto's corpse, a body that witnessed darkness yet remained unyielding, radiating youthful vigor. I love Natsuki Subaru's corpse, the thousand-faced remains torn apart by reincarnation, each piece of flesh recording 486 kinds of despair's fragrance. I love the corpse of the witch Elaina, the traveler's corpse recording information about measuring the world. I love Kamijou Touma's corpse, the savior boy falling into eternal slumber, and I will never let you disturb his death! I love the emotions that living beings show in the face of death, and I hate those undead who walk on the earth with twisted souls. Facing the Undead King of the Great Tomb of Nazarick before him, Ron pointed his spear and glared angrily, saying from the bottom of his heart: "Skull, I will bury the soul within you, and finally, send you into the embrace of death!" The undead civil war between necromancer and the Undead King has begun! My name is Ron, a necromancer who occasionally travels through worlds. Are you trying to say I'm overestimating myself? Sorry, in a necromancer's dictionary, there's only whether I want to do it, not whether I dare to do it!

A mysterious calamity, "Honkai," has eroded the world. Humans infected by the Honkai have become mindless, destructive "zombies," posing a tremendous threat to the world alongside the colossal monsters born from it, the "Honkai Beasts." In the city where this stage play has been repeated hundreds and thousands of times, Hua Yi reaches out to Kallen Kaslana, who has sacrificed herself for the cause. "Would you come with me?" "Yes, I would." He receives a firm reply from the girl, and a smile as radiant as a blooming flower. Standing at the pinnacle of human power...
