Gray finally made a magical girl contract with Ruby.
The reason was that Sapphire was afraid her older sister would harm innocent people on the streets, so she hoped Naoki, the one who could control her, would stay by her side. Sapphire herself went to look for her contractor.
Although Naoki repeatedly said that one magical girl was enough, Sapphire's request was very firm, and plus Naoki also knew who Sapphire would contract with, so in the end, he didn't continue to stop her.
[Oh dear, I thought Young Master would keep refusing Gray-tan to become a magical girl, didn't expect him to agree]
Because Gray was still a child, and children should sleep and wake up early, Gray was now asleep in bed.
While leaning against the glass window, Ruby said to Naoki with quite a surprise.
"You thought I would strongly object?"
[Because you gave off the impression of a foolish older brother, 'Whatever little sister wants to do is definitely not allowed,' 'Leave all matters to big brother,' 'Anyone with bad intentions, don't even think about approaching my little sister'—you gave me that kind of impression]
[That's your misjudgment due to not knowing him well, Red.] Add laughed, [This guy does spoil Gray a lot, but it's not to the point of excessive spoiling at all. When it's time to let go, he lets go. He won't do such brainless things]
[Hoh~~ a very open-minded big brother, then why didn't you agree at first?]
"Are you amnesiac or something?" Naoki flicked his finger at Ruby, "A perverted magic wand like you has wanted Gray to be a magical girl from the start. Even if my brain was kicked, I wouldn't agree to such a thing. Although I respect Gray's wishes, her safety is still the priority."
[Siscon]
"I don't deny it."
Naoki looked towards Gray, who was already asleep in bed.
"Gray's teacher and mother entrusted her to me, so as her older brother and guardian, I must guarantee her safety until she can be independent. Otherwise, I will disappoint their trust in me."
Although he was initially somewhat forced to accept the task of taking care of Gray, since he had accepted it, he had to be responsible to the end. Naoki didn't have the habit of stopping halfway.
[Is that so? Then why do I feel that stupid Gray seems like she will never be independent from you?]
[One's a siscon, the other's a brocon, huh? Truly loving siblings]
Add and Ruby echoed each other in mockery.
His eyebrows twitched slightly, Naoki held up two fingers: "Alright, you two. Toilet or trash can, which one do you choose?"
[Hey hey hey, don't get violent right away, I'm just telling the truth]
[Like a little kid whose secret was exposed and then got angry]
"..."
These two Mystic Codes were really planning on going into the toilet.
"Ah, forget it, Gray is still asleep. If I put you two in the toilet and you scream, she might wake up."
[Truly considerate]
"During the day, you two have to go into the toilet—let's talk about the Class Cards." Naoki changed the topic, "If I remember correctly, there are seven confirmed Class Cards, right? And the Magic Association has already collected two of them."
[I don't even want to question how you know. That's right, as you said, there are still five Class Cards that need to be collected, and the two that have already been collected are in the hands of Rin and Luvia, one Lancer, one Archer]
"Your use of the Class Cards is still limited to limited deployment?"
[Yes, after all, the Class Cards haven't been fully deciphered yet. If you say that... does that mean you know the correct way to use Class Cards?]
Naoki nodded: "Dream Summon—connecting oneself to the Throne of Heroes through the Class Card, layering oneself with the power of the corresponding Heroic Spirit, making oneself an existence similar to a Heroic Spirit."
[A bit similar to Young Master's Fairy Armament, but if you're like adding a plug-in to yourself, then Class Cards are like wearing an outer skin, right?]
"Almost."
As soon as Naoki said that, Ruby understood.
[That means, each Class Card has a corresponding Heroic Spirit]
"Although due to the difference in users, the power of the Heroic Spirit will ultimately manifest in a form different from that Heroic Spirit, broadly speaking, there are these seven Heroic Spirits—King Arthur, Cu Chulainn, Medusa, Hassan-i-Sabbah, Heracles, Medea, and Emiya."
[All very famous heroes—but who is that last one? It doesn't feel like there's a hero named Emiya in any myths. Besides, that's clearly a modern Japanese surname. And you know too much! Although I, Ruby, say I don't care, I actually care a lot—]
Before Ruby finished speaking, Naoki had already grabbed her.
"Gray is sleeping, keep your voice down."
[(Nods nods)]
Releasing Ruby, Naoki whispered: "The Throne of Heroes has no concept of time. Since people from the past can become Heroic Spirits, there's no reason why people from the present and future can't become Heroic Spirits. Emiya is someone with the surname Emiya who becomes a Heroic Spirit in the future."
"—No, calling him a Heroic Spirit isn't quite right either. He's just someone who made a contract with the Counter Force, becoming a guardian used by the Counter Force to keep human history normal."
"As for why I know so much... I went to the Root once. Although I didn't actually enter, just touched the outside a little, but because of that, I gained a lot of knowledge, and coincidentally, some of it is related to the current situation."
[Oh I see, oh I see, the Root... you think—]
"Hmm?!"
Ruby's voice, which was about to rise again, was directly suppressed by Naoki's gaze.
[Sorry... But having gone to the Root, even Old Man Jewel hasn't been there. How could you go?]
Reaching the Root, this was the ultimate goal of every Magus. To achieve this goal, countless Magus spent their entire lives, countless families inherited it from generation to generation.
But such an ultimate goal, in Naoki's mouth, was spoken as lightly as buying vegetables.
"It was just the result of various situations and coincidences coming together, just like a miracle that only happens once in a lifetime." Naoki chuckled softly, "It's fine if you share this information with Tohsaka Rin and the others too. Although I said just leave it to me, they will definitely interfere later. Telling them the enemy's information so they can prepare earlier is also good."
[Then, when do you plan to collect the Class Cards?]
"Tomorrow night."
"Just tomorrow night, I will collect all the Class Cards."
