Lin Shi, who initially thought he'd just transmigrated into a slice-of-life anime world, was somewhat unable to hold back. Luckily, as a transmigrator, he had a built-in cheat code! This isn't random—wait, why is the game starting to display garbled text? (...An infinite flow anime crossover, but the player is a two-dimensional character!)

(Multiple women, multiple women, multiple women—I'll say it three times because it's important!) He traveled through Viserys and even gained Ghidorah's favor. Is this still Game of Thrones? No, I'm invincible, do as you please.

Fatti, transmigrated to the world of DanMachi, starts with a fully-equipped arsenal of three magic spells and seven skills. Unfortunately, his potential is extremely limited, preventing him from seeing further. It's only after accidentally discovering a hidden treasure chest function that his life takes a dramatic turn. He opens invitations to recruit familiars from other worlds, acquiring various magic books and transforming himself from a mage into a noble sorcerer. With the goddess Demeter as his backer, he secretly accumulates strength, manages his familiar, and quietly develops his power. From then on, he cautiously and steadily begins his fantastical life in this other world.

What's it like to be a prince? Excellent looks, extraordinary talent, absolute power... Great, this must be my script for conquering the world! Hehe, I'm going to dominate the world! But when Faust picked up his dance partner's lost shoe, he suddenly realized... This is still a fairy tale world! But can anyone tell me... what does it mean to bring winter with beauty and give madness with song like "Snow White"?

What does it mean to be the "Little Mermaid" who leads the deep blue flock and judges all living beings on land? .................. This fairy tale world seems too extreme. Dude, with these world-destroying monsters around, how am I supposed to dominate the world?! (Annoyed)

Transmigrating into the world of Naruto, and reborn in the Hidden Cloud Village?

Novell looked at Rin Tohsaka across from him, whose eyes were filled with deep suspicion.

"Huh? You're asking me why I'm so skilled at rune magic?"

"Of course, it's all about practice, cough, practice makes perfect."
