[Crossover] I Really Don't Know You!

Kishinami Hakuno once jokingly complained that her birth was practically straight out of a novel. Her father was a mage, and her mother was a miko. That's what people say, anyway. In reality, her father was a mage from Britain's Clock Tower, while her mother was a medium who had once been targeted by a demon. The two met and married, then divorced over their vastly different ideals, leaving behind Kishinami Hakuno, who supposedly had excellent magic circuits but was forced to study the spiritualism she wasn't very good at. It wasn't as though she'd never gone to the Clock Tower out of curiosity about her father. There, one of her late father's friends eyed her as a potential experimental subject, and she had to flee back to Japan with the help of Lord El-Melloi II. She even came face-to-face with the millennia-old demon who had once hunted her mother, and had a pleasant chat with it. Her past had been a bit turbulent, but surely things would go smoothly from here on out... Then, at Lord El-Melloi II's request, Kishinami Hakuno went to Fuyuki to find out why Bazett, who had gone there to take part in the Fifth Holy Grail War, had gone missing. She ended up being forced to participate in the Fifth Holy Grail War herself. "My Praetor! I've missed you so much!" Help! Can Servants really be this familiar? Why is Nero a woman? Why does she act like she knows me so well? And what kind of title is "Praetor"? "Hey! You homewrecker! I've been guarding my master for more than ten years! I'm his true childhood friend, and now I've appeared out of nowhere to save him in his hour of need. In other words, I'm the childhood friend who came out of nowhere! Whoever this emperor is, she can stay away from my husband! Shoo, shoo!" No! I don't know you at all! Who are you? Don't suddenly call me master or husband. This is way too much pressure... "W-what? This little piggy is my manager! You two should be the ones to back off!" Gilgamesh, next door, laughed loudly over his wine. "Not bad, Hakuno! Two beauties in your arms, one on each side. This is the joy of a king! Wahahahaha!" "Oh, no, Master. If you want to keep several boats afloat at once, I'll have no choice but to let you experience my One Husband, Many Wives Castration Fist!" ○ The blurb makes it sound like the protagonist is a playboy, but at heart he's a fox-loving man. ○ The side couples are the golden girl next door and the male Saber from FEX. ○ Even though the blurb spells it out, the male lead doesn't know about it. Until he truly falls for Tamamo, he'll only grow more and more eager to become a monk... It's a one-on-one romance, and he won't return anyone else's feelings. Nero doesn't like him, either. She just thinks, "The Praetor and I are a couple, so every Praetor in the world belongs to me." Theme: For the cutest Tamamo!
