In the next half hour, because Rin and Luvia agreed very quickly and unexpectedly, Naoki kept his promise, telling everyone present about the "knowledge he gained from the Root."
Parallel worlds, the Ainsworths Family, Miyu's background, Emiya Shirou's fight, and the origins of the Class Cards.
"Well, that's roughly it. The Ainsworths Family want to save the world through the Class Cards and sacrifice Miyu, but Miyu's older brother only wants to save his sister, ending the Holy Grail War in one night and granting the wish for Miyu to be happy."
[So, the Holy Grail's way of granting the wish was to send Miyu to our world, and the Class Cards were sent along with her]
Ruby fully understood Naoki's words.
[Because the content is really too shocking, I don't even know what to say for the time being.]
"Agreed." Rin massaged her aching temples, "I didn't expect it to actually come from a parallel world... then? Most importantly, how could you have ever touched the Root?"
"After hearing about Miyu, you didn't feel anything at all?"
"Of course I did, this child is truly too pitiful—but compared to this issue, the Root is clearly much more important! How could you say you touched the Root?!"
Truly typical Magus thinking. Although not like those old fogeys, Rin was undoubtedly a standard Magus. Once the Root was involved, she wouldn't care about anything else.
Luvia was the same. Although she didn't speak, her gaze explained everything.
Picking his nose, Naoki said casually, "As for the Root, it's just because I died once before, and coincidentally touched the Root for a moment."
"A moment?! What do you mean by a moment! Do you know what the Root means to a Magus—"
"I know, but I touched the Root, what does it have to do with you?" Naoki retorted, "After I reached the Root, I didn't gain anything, nor did I lose anything, just saw a portion of the countless parallel worlds. And this has nothing to do with you. Even if you know, you won't directly reach the Root, nor will you gain a way to reach the Root."
"So that's why I said, it's not a big deal."
After saying that, Naoki ignored the two who still wanted to say something and turned to look at Miyu: "Sorry, I have to apologize to you, Miyu. That must be a past you don't want to remember, but I just told everything as I pleased."
"No, it's alright. On the contrary, I'm very grateful that you told me so much." Miyu shook her head, then looked at Naoki earnestly, "Can I ask you for one request? Naoki-san."
"What is it?"
"Please teach me how to use power." Miyu said, "Onii-chan sacrificed himself to save me, and now he's imprisoned by the Ainsworth family. I want to save Onii-chan."
"Sapphire gave me power, made me a magical girl, but I still don't know how to use this power. If it's okay, please teach me."
Emiya Shirou prayed for Miyu to be happy, but for Miyu, the happiness she knew now was living with her brother.
After a moment of silence, Naoki sighed softly: "Back and forth, you siblings... going back and forth like this? You saved me, I save you."
"Is it not allowed, Big Brother?" Gray asked unconsciously.
"I didn't say it's not allowed, don't look at me with that kind of gaze."
Resignedly scratching his head, Naoki said, "Miyu, teaching you how to use power is fine, but that's for tomorrow. Today we still have business to attend to."
"Business? What business?"
"Collecting the Class Cards, just like your brother ended the Holy Grail War in one night, we also have to quickly complete the collection task in one night. That way, we can train you as much as possible before the Ainsworth family comes."
Actually, the best way was still the same as before, letting Miyu fight each Shadow Servant one by one, increasing her strength through actual combat, but since it was all through actual combat, wouldn't it be the same if Naoki became her opponent? At most, it would just be more suffering.
◆━⊰✧⊱━◆
Mystery must be concealed—based on the Clock Tower's rules, which had been violated countless times, the time for collecting the Class Cards was finally set for the night.
When the time showed twelve midnight, in the middle of Homurahara High School's field—
"Here? The location of the Class Card."
Naoki looked around the empty area, then looked at Gray and Miyu.
"Then let's begin, please send me to the Mirror World."
"Yes."
The two children, who had been transformed into magical girls from the beginning, raised the magic wands in their respective hands. The next moment, a large, complex magic circle spread out from Miyu and Gray as its center in all directions, encompassing the five people present.
[Adding an imaginary axis to the fifth measurement variable, preparing for inversion]
[Confirming the existence of a complex space, the central coordinates have been set, forming a reflection path within a two-meter radius, inverting a portion of the mirror world corridor]
Along with Sapphire and Ruby's voices and the rotation of the magic circle, the Mana in the surrounding environment clearly underwent a certain change. Then, as if all objects suddenly shifted for a moment, Naoki only felt a quick flash before his eyes, and when he regained consciousness, he found himself already in a world slightly different from before.
The surrounding environment had basically not changed much from before, but all objects looked like inverted reflections, and the sky also looked like a curtain made of pieces of mirrors.
"Is this the Mirror World?" Gray looked at the mirror-like sky curiously, "It feels like something's different, but I can't explain it..."
[The details will be explained later, the Class Card has manifested, Gray-tan, Miyu, prepare to fight]
As soon as Ruby finished speaking, in the empty ground not far from them, Mana like black mud suddenly gathered, and the powerful shockwave released simultaneously lifted thick dust.
And in the center of that dark red shockwave, a graceful figure with a ruby-studded eyepatch gradually appeared.
"It's here! The manifestation of the Class Card! In terms of Mana quantity, it's already equivalent to a Servant, and can even use a portion of the Servant's power. Gray, Miyu, you two—"
Before Rin's warning could finish, Naoki, who was standing beside them, had already shot forward, and in the blink of an eye, he was in front of Pseudo-Medusa.
Even without using Summoning Magecraft, just using Reinforcement Magecraft, with a body emitting a faint blue light, Naoki directly swung his fist towards Pseudo-Medusa in front of him.
*BANG!*
Without using any techniques, just a simple punch, but for Rin and the others, and even for Pseudo-Medusa, this punch came too fast, so fast that Pseudo-Medusa had just realized and prepared to raise the chains and broken sword in her hands to attack, Naoki's fist had already pierced through her body.
*THUD!*
One punch, a kill.
Pseudo-Medusa fell to her knees powerlessly on the ground, turning into a collection of light spots and disappearing.
Reaching out and catching the bronze card that appeared in front of him, Naoki turned around: "Okay, collected, next location—why are your gazes like that? Like you're looking at a monster."
Because they were indeed looking at a monster!
