Cloverless

A young man finds himself in the world of 'Black Clover' one day.
What did he do next? Did he make the heavens tremble? Did he make the story's every heroine his bitch?
No. No, he didn't.
Instead, he... did an oath...
"I promise, I will safeguard the original story of the anime I loved. I will protect it, I will watch over it, and I will treasure it. No matter at what cost, as this world's singularity, I will take responsibility for my own 'existing' here... I do solemnly swear."
Yes, that is what he exactly did.
Keeping the oath close to his heart, he wishes for the story to continue without hindrance.
Will this vow stand the test of time? Can he, a singularity, will be able to keep a check on himself throughout all of this? Will his tale have a happy ending?
