Fate/Gacha Fate

Neo is a cripple, a disgrace to his mage family, and hated by everyone, his father, his mother, and even his siblings.
They hate him as he is a disgrace to his family, thinking of him as mediocre. However, what they didn't know he is a person who had reincarnated from a world where the current things can be said to a fiction that he read, saw, and watched with enjoyment.
He knows how the future will play out, and he also has a golden finger, born with a cliche protagonist start let's see how his life plays out.

Note: I know the start is a bit cliche and I have done a lot of mistakes for the Fate World, I was quite new to fate at that time, but it has been improved with chapters, and I have learned many things that an Anime or even a Manga Fate fan doesn't know.
