1- The Witcher: Heir of Fire:
The story follows Sebastian, a boy who never truly lived in his first life. Confined to a hospital bed and unable to walk, the only places he could explore were the worlds inside the stories he loved. After death, he is given a second chance by a mysterious goddess and makes a simple wish: to live.
That wish leads him to the Continent, where he is reborn as a Nilfgaardian noble child. After a certain incident, his path leads him to Kaer Morhen, where his memories of his past life return… along with something unexpected.
A system.
And the power of the Flame-Flame Fruit.
2- Shadow Monarch in One Piece:
The story follows Adam, a guy whose terrible power-scaling takes were so unbelievably bad that a literal god decided to punish him for it. His crime? Constantly claiming certain abilities were so broken they could solo entire universes.
Instead of arguing back… the god gives him a chance to prove it.
Adam is reincarnated into the world of One Piece, forced to live there with a power he once claimed was unbeatable. But there's a catch: the power must obey the rules of that world. Strengths, weaknesses, and limitations included.
Adam wakes up as a young Marine who survived the Marineford War, carrying memories from both his old life and his new one. Soon after, fate, or the god's twisted sense of humor leads him to a strange Devil Fruit.
One that grants him the powers of the Shadow Monarch.
But the power turns out to be not exactly how he remembers.
