Castor watched Medea's blank expression silently, waiting for her reaction.
Medea had realized that she lost their little bet and her pride demanded her to follow through their deal. If you ask her opinion, she was extremely unwilling. Deep down, she was afraid that she would truly fall for him and be betrayed after she fell in love.
There was the Ephemeral Romance that slowly encroached her mind to be taken into an account.
Soon, Medea released a morose sigh and then formed a bitter smile. Despite her unwilling expression, her beauty was still there. In fact, it presented a unique charm due to her melancholy.
"I lose, huh?" She mumbled sulkily.
"It looks like it," Castor replied carelessly, eliciting a glare from the Elvin Servant.
Medea was aware of it, and Castor didn't need to rub it on her. It was only normal that she wasn't amused by Castor's careless retort.
"So, what's now? Are you going to start chasing skirts?" asked Medea coolly.
Castor raised his brow in bemusement at her cool and apathetic expression. Then, he shook his head in a silent denial, surprising Medea, though she hid her surprise well.
"Nah," he stated, "I have my standard. Well, after spending time fucking you, my standard has gone up. I'm going to take a woman that can match your beauty or someone unique, I suppose."
Medea blinked her eyes slowly, befuddled. She never expected that.
"I see…" she replied, "Well, do what you want. I lose our bet. I'm going to play the role of your obedient and supportive wife to honor our agreement."
Medea paused and gave Castor a terrifyingly blank expression.
"But, remember this well. If you dare to betray me, I will make you pay even if it kills me."
Castor smirked silently in response to Medea's threat. He wasn't scared of her threat. Not after creating a bunch of ridiculous magicks that would ensure his survival.
"Don't worry. If you play your role well and not bore me, I am going to keep you as my favorite forever."
"Hmph! A frivolous man like you usually can't keep his words, but I'm going to play along. Be grateful that I put aside my pride to play this ridiculous farce," said Medea.
Castor didn't respond to her exclaim and opted to squeeze Medea's soft and bouncy butt cheeks. Medea rolled her eyes at his perverted antics.
Silence enveloped the room until Medea broke the silence, saying: "So, do you have the intention to win this Holy Grail War? Obtaining a wish-granting device seems interesting."
Castor stopped playing Medea's buttocks and met her curious gaze. He pondered for a little and then replied: "Well, I have no interest in this Holy Grail War except for Saber and her fake Master."
"Would you kindly explain your interest to them?"
"You see, Saber's real identity is King Arthur. And the King of Knights is actually a girl…"
"Excuse me?" Medea abruptly cut him off, apparently incredulous, "The King of Knights is a girl? You're kidding, right?"
Castor swiveled his head to left and right and then said: "No. I was not joking. If you don't believe me…"
He paused and used the Scrying Magic to get a glimpse of Artoria. He then created Illusion Magic to project what he'd seen into space in front of them.
Medea blinked her eyes, apparently curious by the magic that Castor cast. But, she put aside her curiosity for the time being and focused on the image projected by Castor's illusion.
"Is that King Arthur?" Medea watched the image of a young girl in a royal blue robe with braided golden hair styled in bun and green eyes. There was also a woman with snow-white hair, red eyes, and beauty that felt artificial. She easily deduced the true nature of the red-eyed woman. A homunculus.
When she got no answer, she turned in Castor's direction and saw him looking at the homunculi and Saber intensely. Passion, greed, lust, and desire were there.
Annoyed, Medea pinched his nipple, getting his attention.
"What?" Castor asked with a furious scowl. Although it wasn't painful, he felt annoyed by Medea's interruption.
Medea presented an unamused expression, but her heart palpitated in fear and anxiety, scared of incurring the wrath of an absurd existence like him.
After recovering from the short burst of fear and anxiety, she presented a thin smile and spoke up in a bland tone.
"You're drooling at them, dear."
Castor blinked and then rubbed his mouth and lower jaw to clean his drool but found nothing there. He frowned when he realized that Medea had pulled his legs. He was about to snap at her but stopped when he saw her amused, sultry grin.
He decided to let her teasing go unpunished. At the very least, for the time being. But, he silently promised to fuck her silly until she fell unconscious later. If he used one of his latest created magicks to read her thoughts, he wouldn't have missed the fact that she really wanted to laugh at his foolishness and gullibility, but she hid it well.
"So, is that girl the Legendary King of Knights?" Medea repeated her question and received a silent nod from Castor. Her eyebrow twitched slightly when she found Castor ogling Saber and the homunculi.
"Do you want to take those two?" She asked with a neutral tone and expression.
Inwardly, Medea felt unwell because it truly hit home that she would share her man with many women whom he fancied. It hurt her pride. Moreover, she wondered if this was how Hera felt about her husband's cheating habits.
It was when she felt empathy and pity to the Queen of Olympian Gods, something of which she wouldn't even entertain in the past due to her disdain and hatred for Gods.
"Yeah. I'm gonna get those two."
"I can understand King Arthur. She's a legendary figure and quite cute, after all. But, why do you want that doll too? Don't tell me you will fuck anyone with a pretty face? Never mind. I think I know your answer."
Castor rolled his eyes at Medea before shifting his attention to Saber and Irisviel. Inwardly, he fantasized himself fucking the virgin King of Knights, deflowering her, and cuckolding the infamous Magus Killer and ravishing his gorgeous wife.
Imagining such immoral acts, Castor felt excitement and arousal. He wanted to go there and drag them to his bed. But, he decided to wait until they arrived in Japan. It was when he recalled the fight in the dock that was attended by all Servants except Bluebeard.
"I guess I'm going to kill Gilgamesh, Diarmuid, Iskandar, and Lancelot when they are in the same place later…"
"What?"
Medea gazed at him, surprised after she heard his carefree words. It wasn't hard for her to get the information about those legendary heroes from Grail and make a conclusion that they were likely Servants in this war if her Master's words were correct.
