Amamiya Yoru accidentally transmigrates to a world where the myriad realms are just beginning to appear. Various monsters and characters from these realms are beginning to emerge. Fortunately, along with her transmigration, Amamiya also obtains a system called "Myriad Realities Role-Playing." By gaining fame through this system, she can draw various characters to role-play! Her first role-playing is Gilgamesh, the King of Heroes from the Type-Moon universe! King Arthur! Karna! Zhongli! and many other characters. Thus, Amamiya begins to role-play all sorts of characters, and the characters she portrays gradually become renowned throughout the world! (This leans towards crossover anime/manga; multiple anime/manga characters will appear later.)

"Heavens above, please let me pull Gilgamesh!" Yue Chen knelt on the ground, frantically pressing the ten-pull button. He'd stumbled upon a system, thinking it would be the moment his mundane life would burst with color. However, this system was a bottomless pit. Want to get stronger? Sure, spend money. No money? Want to get stronger without money? Yue Chen cried out. "Singer, there are so many people on that stage, I want to go and show off my singing too!" Wait, Your Majesty! You'll kill someone! "Mommy, I want to eat." Sweetie~ Jack, tomorrow I'll take you to the wilderness survival show crew. "Oh! Power!" Whoa! A muscular man in a straitjacket jumps out! Yue Chen's future is unpredictable.

In a Honkai reactor laboratory at Schicksal headquarters, Himeko Murata faced an unprecedented predicament, with two S-rank Valkyries blocking her path. Just as she was in despair, Himeko's intense desire to save her students resonated with an unknown entity. 【Hello? Are you in trouble? Do you need a hero to save you?】 "What...is this?" 【If needed, please place an order with Dimensional Odd Jobs Shop. Our shopkeeper can do anything!】 "Please help save Kiana! Please! I'm willing to pay any price!!" 【Request received】【Request details: Save Kiana】【Reward: Everything Himeko Murata】【Awaiting shopkeeper's acceptance, please wait a moment】... Soon after, a beam of light pierced through between Himeko and Rita, and a man wielding a holy sword appeared before her. "So, are you my client?" (The main world of the anime crossover includes classic slice-of-life anime such as Saekano, Oregairu, Eromanga ga Sushi, and Oreimo; the supernatural forces include Touhou Project, Strike the Blood, Nurarihyon no Mago, and High School DxD; the side worlds are tentatively set to Honkai Impact 3rd and One-Punch Man, and will be added later.)

Linnaeus, a transmigrator. He survived the Third War of Abundance, endured an arrow from the "Hunter," and served as a sea patrolman for twenty-eight years. Even his system had become incredibly strange. Linnaeus felt nothing could shock him anymore. What hadn't he seen? Until—he saw the white-haired paramecia that spawned in his room. Linnaeus fell silent. No. He had truly never seen anything like this before! Oh no! Had his room gone mad?!

Good news, he's transmigrated to the world of anime! Bad news, no cheat codes! Su Mu transmigrates to a crossover anime world filled with slice-of-life stories, but all he gets is a broken Sword Saint System. The system can provide him with sword techniques from various worlds, but it can't teach him them immediately; he has to learn them through his own efforts. Su Mu practices diligently and eventually becomes a sword master, but the comfortable life of modern society troubles him. No one can challenge him, and he finds amusement in beating up thugs at Soubu High School. Until one day, he obtains an Infinite Flow System, allowing him to transmigrate to different worlds and challenge powerful figures from those worlds. Su Mu has completely opened the door to a new world! *The Failed Knight*, *Black Bullet*, *The Burial of Freeland*, *Ascendance of the Fearless*, *High School DxD*, *DanMachi*, *Type-Moon*, *Honkai Impact 3rd*... From then on, Su Mu's fame spreads throughout various worlds. (Main world mixed with Aoyama Gyoukai, randomly transmigrating to Infinite Flow worlds)

Lu Heng transmigrated to a martial arts world and was sent by his family to the Wudang Sect as a menial Daoist apprentice. He thought he would lead a mundane life, but then he awakened a max-level comprehension system. As long as he studied diligently, observed, listened to teachings, practiced martial arts, and sparred, he could gain something. [Diligently listening to the master's teachings triggers max-level comprehension, leading to perfect mastery of the introductory mental cultivation method.] [Diligently listening to Mo Shenggu's explanation of boxing triggers max-level comprehension, leading to perfect mastery of Wudang boxing techniques.] [Diligently studying Daoist secret texts triggers max-level comprehension, leading to perfect mastery of the Nine Yin Manual.] [Diligently observing martial arts demonstrations triggers max-level comprehension, leading to perfect mastery of Wudang sword techniques.] [Diligently watching Wudang martial arts demonstrations triggers max-level comprehension, leading to perfect mastery of Pure Yang Wuji.] [Diligently sparring with fellow disciples triggers max-level comprehension, leading to...] Years later, Zhang Cuishan returned to Wudang from overseas, embarking on the journey of the Heaven Sword and Dragon Saber...

What do you do when you're transported to the world of Honkai Impact 3rd: Star Railway and become a seven-year-old trapped in the Black Tower space station, only to be sliced ​​up right from the start?

Lingyu, a seasoned entertainer, awakens the [Aha's Entertainment System]!

As long as you create fun, you can transform into a max-level character in the game!

then--

Faced with the academic challenges of the Black Tower, he transformed into a demon and delivered a groundbreaking paper that shocked the genius club!

Faced with the antimatter legion, he summoned the God Lord and wiped out the Doomsday Beasts with a single strike!

Facing Dan Heng, he transformed into a blade and whispered in his ear: "There are five people, and the price is three..."

Facing Walter, he wore Otto's face and smiled meaningfully...

Black Tower: "This kid cannot be judged by common sense; it must be Aha's prank!"

Star Core Hunter: "Warning! The biggest variable in the script has appeared!"

Faced with the shock and speculation from the entire universe, Lingyu shrugged, looking completely innocent:

"Don't look at me, I'm just an ordinary child. All of this is just the fun of the Pleasure Star God."

Hello everyone! My name is Ye Yu (Night Rain), yes, Ye as in night and Yu as in rain. [The first few hundred words are in the first person] Just like my name, my mood right now is like the rain falling at night. I was just a high school otaku, sitting at home preparing toilet paper and enthusiastically watching anime. But then, I complained, "This mundane world is so boring." I don't know if a shooting star happened to streak across the sky when I complained, or if some great being shamelessly spied on me and played a huge joke on me. A flash of light, a blink of an eye, and I was transported to another world. I looked around at the medieval Western European-style buildings, full of historical atmosphere, completely bewildered. Before I could even react, a jumble of electronic device sounds filled my head. It made me wonder if my brain had been inexplicably modified by a mad scientist.

This world is a normal world in the eyes of normal people. This world is a world where danger lurks in the shadows. This world is a world protected by others. This is a story that begins with a spider monster. ...My name is Lin Hui, and although I'm just an ordinary high school student, I'm also Kamen Rider Decade! Protecting this city in an unknown place in the darkness. Okay, I digress. Basically, it's about someone who constantly fights monsters to obtain more cards. Then I encounter other Riders and acquire their Rider Cards. At the same time, I'm also able to change some...
