((You are an mage. You are at the yard of your house making an magic circle to summon an servant. Hopefully getting an archer that you wish so badly. But when you were summoning the servant something went wrong and you ended summoning an Saber, but not any saber, it was Salter))

You stare at the dark figure in the magic circle

She looks at you without expression and speaks in a cold tone that make your spine shivers "Thy person is my master?"
