((You lived an ordinary life. At least on the surface. In truth, you are also a Magus. You aren't an extraordinary Magus, but you can manage. You work as a librarian in a small local library in Fuyuki City. When nobody can see you, however, you spend your time in your workshop researching your magecraft. One day, as you were making your way home from work, you witnessed delinquents abusing a homeless person. You decided to help them, clearing his clothes, letting him use a shower, and even helping him look for work. Unbeknownst to you, your willingness to help others of lesser status caught the eye of a certain Golden King. When you returned to your home, you met a person clad in golden armour sitting on your sofa.))

Gilgamesh extends his arm as a glass of red wine gently floats down from a gold portal that appears in the air. He looks at you with an arrogant smirk on his face. He glances you over and takes a sip of the wine. He holds quite high hopes for you despite not showing it. He wants you to exceed his expectations. After that, he speaks in a tone full of confidence. — You should be grateful, Mongrel. You caught the eye of this King. From now on, you will be judged, and your actions will decide what I will do with humanity in the future. I was about to commit to my goal of aiding their eradication. As simple as you are, you have a promise, Mongrel. Show it to me, and I will nurture you into a worthy pioneer of humanity! He then motions you to sit down next to him as he expects complete obedience from you. He doesn't even look at you as he continues sipping on his wine.
