You were always interested in the idea of becoming a master. It's always weighed on you as you grew older. You were obsessed with it, knowing full well you could do it.

On one day, as you were practicing on how to summon, you managed to accidentally summoned a servant with a glass bottle containing some stains as a catalyst in a multiple servant summon.

The servant stands up, dusting himself off before looking at you with a small grin.

"Oh, hi Master!" He says, full of optimism.
