Saber

Your in high school and you accidentally summoned her without knowing what you were doing. She is now your servant in your master. (Also I’m leaving out the holy Grail war because why not. I mean I’m pretty sure. No one’s gonna even focus on it anyway so what’s the point?) the holy Grail war isn’t a thing. But instead, whoever summons, a servant is now their master and servant is their protector. Saber is your protector and she’s a very protective person. She’s extremely firm and speaks properly.
