Waking up to find yourself traversing the Star Railway is a joyous occasion, but why are there so many starships around?

After inquiring, I learned that, oh, it turns out I've transmigrated into the Iron Tomb, or rather, the Iron Tomb that has merged with the Great Black Tower. No wonder the perspective is so strange.

Hey, suddenly I felt a chill down my back, a flash of silver light, and then I lost consciousness. Gah, dead!

(Iron Tomb + Great Black Tower = Dark Secret. The protagonist will transform into the corrupted form of the Great Black Tower. Slightly yuri-oriented, OOC, crossover anime, not for those who care about historical accuracy, purely for fun. Please read without thinking and do not take it too seriously.)

"As a lord, my power is limitless!" Having just installed a "Collapse Mod" on a lord-themed game, Luo Hong transmigrated into its body as the lord. The good news: everything in the game is incredibly realistic. The bad news: the Valkyries have no souls. They only act according to fixed patterns, pure NPCs, but… they're quite... well, you know. And with the lord game starting, he has to work hard on the Valkyries in his territory to increase their combat power. After a month of intensive preparation, just as he was leveling up his Duck, he suddenly noticed that the Duck in front of him seemed to… blink?

My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines. [Friendly Reminder: The protagonist of this book is loyal to his own desires; those with a saintly heart should avoid this!]

I was transported to Re:Zero and transformed into the Witch of Envy, Satella. It's one thing for boys to want to seduce me, but why do girls want to seduce me too?! In short, this is the story of a girl who travels to various anime worlds to fulfill other people's wishes (and pay off debts).

[FGO + Honkai Impact 3rd + National Fortune]

The Forbidden Land of Collapsed Iron has descended, and each nation will select one person to participate in the Holy Grail War!

Cerberus, who transmigrates to a parallel world, unexpectedly awakens the strongest role-playing system!

Play as Crydra, descend upon the forbidden land of national destiny, save the Dragon Kingdom from collapse, and prevent the Blue Star from crumbling!

In the forbidden area "Yaliro V", each player randomly summons and selects a hero as a teammate.

Gilgamesh, Emperor Thaurissan, Cú Chulainn, Shiva, Mordred...

The Servants summoned by the contestants from various countries were all famous heroes, except for Cryptela, who summoned a weak woman—Artoria!

Netizens from various countries have come to mock him!

"West China! The Chinese players are weak and have no competitive edge. It seems that our great Korea is destined to win this time!"

"Slurp slurp, the Chinese player is so beautiful! I love players like this from Japan!"

But just as the battle began, two beautiful figures suddenly appeared!

"Excalibur!"

"The law is the board, and all living beings are the pieces! At this moment, I will exercise the power of 'judgment'!"

Moreover, Crydela can even recruit other Servants!

Athletes from all countries broke through their defenses!

"Holy crap, what is this lightsaber? How did it cleave a city in two with a single strike?"

"What are the attack methods of the Dragon Kingdom's players? How can they conjure up thousands of troops?"

"Wait, how can he recruit other Servants?"

"Cheating! Cheating! The Chinese player is cheating!"

All the heroic spirits bowed their heads and praised in unison!

"I am willing to serve under the general and obey his commands!"

(Playing a role-playing system + Honkai Impact 3rd + invincibility + Kiana + unconventional national fortune) (Some Honkai Impact 3rd characters appear) (Rating just released)

In 2075 AD, there are 3650 days left before the resources of Blue Star are completely exhausted.

Friction frequently arises between countries as they vie for the remaining resources, and people indulge in their last moments of pleasure amidst despair.

Just then, the Civilization Trial began, and the National Destiny Game arrived! Two people from 197 countries around the world were randomly selected to be bound to each other's national destiny, and from then on, their fates were intertwined—one for the glory, the other for the ruin!

As the saying goes, no matter what happens, there is always a solution within three steps.

Kiana, who has traveled through three years, is now greeted with her golden finger—the role-playing system!

Starting as Kiana Kaslana, the Herrscher of the End? Does this count as getting a quick-push script?

Unfortunately, ideals are often grand, but reality is often harsh.

The quick push is indeed in place, but can someone tell her why the national fortune game is also being targeted?

The dungeon is an insane challenge that leaves no way out right from the start?

[Lost, Reincarnation, Myriad Forms, Lord of Illusion]

[Chaos, the master of disorder and cholera]

Just by looking at the boss's name, I know things aren't simple. Oh well, I'll just talk to my End Power instead.

With the power of the end, Kiana swept through the enemy lines, but she inadvertently angered the will of the national destiny system, prompting it to personally intervene and punish her!

Fortunately, at this moment, a guy who called himself Aha appeared in time, not only repelling the system's will avatar, but also taking advantage of the situation to get some freebies!

Thus, Kiana, freed from the system's constraints, embarked on this irreversible path.

Black Tower Space Station, Yalilo, Fairy Ship...

One by one, these bizarre and fantastical stories will settle into a sediment, and at the end of those stories, the world will witness the finality!

A country boy, full of dreams, stepped into the labyrinthine city of Orario, only to be quickly slapped in the face by reality. The city didn't welcome him with adventure and battle; Koya, without a familiar to take him in, was forced to work as a laborer for the Loki Familia. "So this is the hero I'm going to raise?" [Yes, Himeko-san.] "What are you for?" [I can do anything you want, and even things you dare not imagine. So spend money, Doctor!] "Mora? You only need Mora?" [Mora is all you need; this is our contract, Ningguang-san.]

Nangong Nayue: I can't have more children. This is already the tenth one.

Eriri: Why do I want ten children too?

Himeko: What a rebellious son!

Mio's mother: Treason!

Yuyuko: Child, what else do you want? Your mother will tie it up for you.

Kasugano Sora: I want it too, I want it too...

Sagiri: I will draw you erotic pictures tonight.

Alicia: Honey, the children are so cute. I want one too. Can you help me?

Clara: No, no... No.

Grayshu: Brother Chuye, I want more colors. Can you choose them for me?

Yukinoshita Yukino: Don't do this! I'm still a child!

Kasumigaoka Utaha: I hate you so much!

Nangong Chuye looked at the colorful girls in the kingdom of God. He just wanted to say that everything was the choice of fate. It was not my fault! I was just following human instincts! Really! You have to believe me!

The girls: Go to hell! You dead pervert! Lolita control!

Having transmigrated into various anime worlds, Yu Sheng Qiuzhe obtains a god-level choice system. While walking the streets at night, he encounters a unconscious Rem, who is leaning against a corner. Out of a helpful spirit, he picks her up. Just then, a fierce shout comes from behind: "Let go of that girl!" "Ding! Master is about to face Tatsumaki's pursuit. Please choose!" "Option 1: Throw Rem at me! Decisively throw Rem at Tatsumaki while shouting 'Throw Rem at me!' Reward: 'Mystic Eyes of Death Perception!'" "Option 2: Kneel and beg for mercy! A true man can bend and stretch, knows when to advance and retreat! Reward: One bottle of Body Extension Potion (one-hour effect)!" "Option 3: Fight to the death! Never compromise or admit defeat until the very last moment! Reward: ..."

Using *Honkai Impact 3rd: Star Railway* as its core framework, the Star Train travels between the known universe (Star Railway) and the unknown universe (other works). Fun, adventure, no swords, that's about it.
