Over the next two days, Jiang You's routine remained largely unchanged. After work, he would first check the preliminary rounds of the Duel Tournament in Fuyuki during the Fifth Holy Grail War. The number of Magus appearing in Fuyuki had increased significantly, and the quality of their Decks had also improved considerably compared to the first tournament. Having gained some insight, Jiang You's "sweeps" yielded more interesting Cards, though most were more for collection than practical use.
Once the preliminary rounds ended and night fell, it was time for his arranged duels with the Magical Girls. Prisma Illya and Miyu showed remarkable progress; by the second day, they had already learned to control their magical power output. Consider that a certain nameless Heroic Spirit, capable of single-handedly defeating someone called Gilgamesh, had spent years honing his wooden staff before it exploded from overuse.
By the third day, though they still lost, Medusa gained little advantage. In fact, her attempt to unleash her Noble Phantasm was directly interrupted. Miyu and Prisma Illya had realized that without her Noble Phantasm, Medusa lacked a decisive attack. By restricting her Noble Phantasm use, they could significantly reduce the difficulty of the battle. Medusa felt like her entire strategy was being targeted, but if that were the case, dealing with her irrational, corrupted self should pose no further problems.
"I'm sorry I didn't force you to use your full strength, Sister Medusa," Prisma Illya gasped, sprawled on the ground. She had lost again, but she was confident she would win next time, determined to show Jiang You her true power.
"Actually, I was using my full strength," Medusa replied, both pleased and embarrassed. She was pleased to have helped them, but embarrassed that after only three days, she had already taught them everything she knew. This realization left her feeling profoundly inadequate. She could only apologize for being a second-rate Heroic Spirit.
"Dealing with my corrupted self next will be no problem at all. Just use the same tactics against her, and you'll win easily. Good luck with your campaign!"
"Congratulations again, truly," Jiang You emerged from the shadows once more, clapping as he approached the group, radiating the air of a mastermind pulling the strings.
"Stop playing that game already!" Prisma Illya's attitude had become much more casual since discovering Jiang You wasn't so serious after all. "You were just playing on your phone over there! The screen's glow revealed you perfectly. Just stick to being a comedian!"
"But staying there is really boring."
Jiang You idly searched for information about this world on his phone, finding it surprisingly comprehensive—almost too complete to be randomly generated. But if it had been specifically designed, it wasn't entirely impossible. The old game GTA5 had a similar feature on its mobile version, and it was quite thorough.
"I need to kill time somehow. Anyway, since Medusa isn't serving much purpose anymore, she should leave this world."
"...You're saying that on purpose, aren't you?!"
Prisma Illya didn't believe Jiang You was that kind of person. If he really were, how could Medusa be so close to him? Over the past few weeks, Medusa had interacted with them beyond combat, proving to be a gentle and caring sister. Medusa had even mentioned that with Jiang You's help, she and her sisters had acquired a house far from the crowds, where they could live freely together.
She must be quite the reliable Big Sister to her sisters, Prisma Illya thought.
"Your routine is outdated. Can you try speaking normally for once?"
"Tch... How boring."
Prisma Illya was far too perceptive, which took much of the fun out of things.
"In any case, the Medusa combat simulation is essentially unnecessary now. You've already familiarized yourselves with her fighting style. Since it wasn't a death match, Medusa couldn't fully demonstrate the terror she inspires as a legendary monster. I'll give you a score of 90 for this round."
"90? Not 100?"
Prisma Illya stood up, hands on her hips. "I demand an appeal! Your scoring system is opaque and lacks transparency! It has no credibility whatsoever!"
"Where did you even learn all this strange nonsense...? Besides, another word and we're switching to a thousand-point scale. Still want that dessert reward?"
Dirty adults are masters of appealing to self-interest.
"There's a reward? Then I wholeheartedly endorse the esteemed Mr. Jiang You's scoring system!"
Prisma Illya's sudden shift in demeanor was truly remarkable. Once she warmed up, she proved to be quite lively.
"Alright, we'll be starting live combat in three days. Medusa and I will be providing backup, so you can fight without holding back. We've got your backs."
Jiang You felt it was about time for a practical test. This scenario wasn't part of the original storyline, so he figured that Prisma Illya and Miyu, whose Level Up abilities were restricted, would easily handle this battle.
"Three days from now... Perfect! That's the weekend, no problem!" Prisma Illya counted on her fingers to confirm the date.
"Although I've enrolled in school, I haven't officially registered yet, so I'm free whenever. Even after school starts, Mr. Jiang You, I'll rush over whenever you need me," Miyu reaffirmed her commitment.
"So, you're saying you can take three days off, right?" Prisma Illya looked at Jiang You expectantly. The recent intense battles had left her feeling rather tired, and she was eager to use this time to rest and recover.
"What are you daydreaming about?" Jiang You snapped his fingers, and a popular character clad in purple magic robes appeared before them.
"Miss Medea, she's your second-wave opponent. By the way, the second round is a consecutive battle. After defeating Caster Medea, the legendary King Arthur—Artoria—will immediately join the fray!"
"Tell me, what is it this time?"
Medea was already accustomed to being bossed around by Jiang You. After all, the compensation he paid her was enough to keep her employed for centuries.
"You're telling me these two kids plan to defeat me in battle? Are you serious?"
"When have I ever lied to you?" Jiang You retorted.
Next, Jiang You summoned White Lancer Artoria. Though he possessed the other King Card, his Bond with it was insufficient for direct summoning. Thus, he settled for White Lancer Artoria as a substitute.
"Ehh?! King Arthur is such a mature woman?!"
Prisma Illya's eyes remained fixed on White Lancer Artoria's figure, completely transfixed. Originally, her goal had been to become a mature woman like her mother, but now she seemed to have set her sights on an even grander aspiration.
"What's so strange about that?" Medea asked, assuming Illya was her original self. She shot Jiang You a curious glance, thinking to herself, Letting your Master dress like this? You two are really getting wild with your Master-Servant games. "It's not like you haven't seen a female Flying Dragon servant named Lancelot before."
