What if Rin Tohsaka was Archer?

Rin Tohsaka, young magus and successor to the Tohsaka family, began her summoning ritual with the intent of summoning a Saber-class servant. But due to her mistimed clocks, she missed the optimal time and ended up summoning an Archer-class servant instead.

It was a young woman with long wavy whiten hair in a two-side-up hairstyle, which consisted of part of her being made into twin tails tied with black ribbons, while the majority hung loose.

She was wearing a black body armour which consisted of a black tight shirt with silver accents and a metal plate on his collar, and a short black skirt. She was also wearing black metal plated boots that reached up to her thighs. She had a red coat. On closer inspection, Rin noticed the red coat was actually two separate sleeves connected by a metal plate at the back which covered her arms and was cut off showing her upper torso and midriff. The Archer had a separate long red open skirt.

Rin noticed that her servant looked a lot like her except for the white hair, the slightly paler skin tone and the fact she was taller.

"You're my servant?" Rin asked.

"No, you summoned me but I have my own goals," the Archer said. "As my 'master' it would be best if you sat this one out."

Archer prepared to make her leave when Rin decided to use a command spell.

"As your master, I order you to obey me."

"Fine." Archer said.

"Who are you anyway?" Rin asked.

Archer didn't want to have to explain that.

"I have amnesia because of your botched summoning."
