The Mysterious Servant

Gudako, the female Master of Chaldea is a lonely woman. She is bullied by Gudao and his Servants as well as most of her servants. The only ones by her side are Salter, Jalter, Mordred, and Mashu. They are something more than just Master and Servant though, cause they are in a relationship with each other. Now even though her having a harem full of beautiful girls would be something to celebrate, the bulling completely counters that. But one day during a summoning she summoned something that is not summonable, something that is completely out of reach. Well almost out of reach, the holy grail is the only thing that can somewhat touch this existence. The only reason why she was capable of summoning this existence, was because it pitied her. At least that is the reason it uses but the real reason is only known by said existence. Follow Gudako and her loyal Sevents as they uncover the mysteries of the newest Servant of Chaldea.
