"I've become smarter..."
Takumi looked at his hand, his gaze calm.
It seemed like thirteen years had passed in the dream, but it was thirteen days of martial arts practice in his heart.
The ignition of the [Heart of Fire] was like he had finally achieved enlightenment. Various knowledge that was originally obscure and difficult to understand could now be comprehended thoroughly. It even gave Takumi a feeling that he could learn and understand anything.
During the thirteen days, the Servants who once lent him power, or the Servants he once encountered, all became opponents in his heart, fighting with him again and again, displaying their respective martial arts in his heart.
And Takumi was like a sponge, absorbing all this intelligence and integrating it into himself.
'The current me, in terms of martial arts, won't be afraid of anyone I encountered before!'
Naturally, during this time, besides achieving enlightenment, Takumi also figured out the effects of the [Heart of Fire].
First.
"Power that changes constantly and follows one's heart."
Its manifestation was the different usages of Noble Phantasms belonging to Jeanne, Siegfried, Romulus, and others in Takumi's hands compared to their original forms.
No matter whose Noble Phantasm it was, as long as it reached Takumi's hands, it would become Takumi's shape.
Its usage form would transform into a state more suitable for him according to Takumi's mind and traits.
That was why there was the chant-less [Mon Coeur], the [Balmung] that charged while slashing, the towering tree, the mobile labyrinth...
It was precisely because of this that Takumi could quickly master the power of various Noble Phantasms and use them.
Second.
Reforging oneself.
The Servant power in Takumi's body was spiritual information intercepted by the [Heart of Fire] after the Servant's Spirit Origin shattered.
Although it made Takumi's stats look quite good, various information was too mixed and couldn't be fully used by Takumi.
But under the reforging of the [Heart of Fire].
Strength: A → A+
Endurance: A → A+
Mana: B → A
The stats changed. Besides this—
Personal Skill Change/Upgrade:
[Rune Magecraft (A)] → [Primordial Rune (—)]
[Revelation of the Heart (D)] → [Revelation of the Heart (C)]
[Dragon's Core (E)] → [Breath of the Planet (A)]
[Dragon Slayer (D)] → [Dragon Slayer (C)]
[Riding (C)] → [Riding (B)]
...
Almost all skills advanced one step closer to the ranks the Servants who once gave Takumi power should have.
Some even mutated.
And Takumi, who re-burned and consumed all the borrowed Servant power, had nothing to do with the concept of Servant itself anymore.
Like Mordred analyzing Takumi's power before; if asked to do it again now, she couldn't do it either.
"So my class shouldn't be like borrowing Cú Chulainn's before, but should be—Foreigner!"
After reforging, Takumi had found the class truly belonging to and suitable for him.
Third.
"Did I seem to have unknowingly spread my emotions and heart to others before?"
Perhaps precisely because of this, friendly Servants along the way would have high favorability towards Takumi upon first meeting.
Because Takumi could be said to be exchanging sincerity for sincerity. The trust and love for Servants when playing games and watching anime were unconsciously transmitted into their hearts.
So much so that Servants probably had a vague but inexplicably real understanding of Takumi himself as soon as they met.
So Nero and others treated Takumi so well. So Drake and others felt Takumi always looked worried because Takumi at that time never thought he could solve Goetia.
So at the end of the Third Singularity, obviously having just met David and Atalanta, they ran over to fight with Takumi and others as if there was no gap, wills unifying instantly.
However, precisely because this was exchanging sincerity for sincerity, Takumi possessing the [Heart of Fire] seemed to have more intense and sensitive emotions than ordinary people.
Leading to Takumi, who finally left the sickbed, caring so much about Jeanne whom he met first and pulled up himself, and being so sad about the departure of Jeanne and others.
Presumably because of this, the somewhat heavy-hearted Takumi gave Jeanne and others the setting of disappearing as soon as he turned his head in the subconsciously constructed "Prison Tower."
After all, as long as conquering Singularities, no matter how well they got along before, they would part, wouldn't they?
Besides this, Takumi also had no room to lie. As long as he lied, the other party would definitely be able to detect it.
Even if Takumi himself were a villain, relatively righteous Servants might not beat Takumi up, but how could they help Takumi?
Fortunately, it seemed that before the [Heart of Fire] ignited, although Takumi wasn't clear about what happened, Servants didn't reach the level of reading Takumi's mind.
As for now after ignition, this mental diffusion was just stronger than before. Even Takumi himself could continuously and consciously touch other Servants' moods.
Instead of detecting Jeanne Alter's crying, Nero's love, and the final heart-to-heart conversation with Asterios only under mental agitation like before.
Fourth.
"Two Noble Phantasms are being forged in the [Heart of Fire]. They are armaments truly belonging to me."
Takumi muttered to himself clutching his heart.
Clang—clang—clang...
He could hear the slow but powerful sound of hammer strikes in the flames.
Along the way, Takumi's sights and hearings, the giving of Servants' Spirit Origins, every mental agitation... all seemed to be adding fuel to the [Heart of Fire], adding raw materials for "forging."
Just for today's ignition and forging.
And although a bit unkind, the residual Spirit Origin information of Servants, except for those completely fused by himself, the remaining residues and dregs indeed all became one of the raw materials for the two Noble Phantasms, being beaten continuously now.
"Phew..."
Sorting out his harvest, Takumi exhaled deeply.
The breath was long, like a giant beast entrenched between heaven and earth. The sound of breathing echoed faintly in the empty Chaldea.
Accompanied by Takumi's breathing, a large amount of magical energy surged from the heart, circulating everywhere in the body along the blood.
Speaking of which, it was wondrous, and this was also the reason Takumi would define the [Heart of Fire] as "power capable of causing miracles."
In the previous few Singularities, Takumi used magical energy through "Magic Circuits."
Including using Rune Magecraft was the same.
But funnily enough, as a Foreigner, Takumi didn't have this Type-Moon specialty in his body at all.
Then why could Takumi use "Magic Circuits"?
Because under Takumi's persistence for more than a month, the [Heart of Fire] forcibly simulated "Magic Circuits" in his body!
Thus making Takumi only able to use magical energy to start a fire before obtaining [Rune Magecraft].
Realizing this, Takumi didn't want to say "turns out I limited my potential" anymore.
Who could know that I didn't need those low-level Magic Circuits at all?
Chaldea's magic books didn't mention it to me either!!
