Hah!
Rin landed an Iron Shoulder Bash on Lorelei's chest, but it had no effect on Lorelei, who had activated defensive magecraft, only causing Lorelei to step back slightly.
Rin panted heavily as she looked at Lorelei, who was still breathing steadily. 'Damn it, although this person isn't good at fighting, it's really too difficult to deal with her when combined with magecraft. She truly lives up to being the pinnacle of modern Magi. I must change my strategy.'
Rin launched an attack on Lorelei again, while secretly throwing a ruby onto the ground.
Lorelei looked at Rin, who was pressing her lips together and saying nothing. A mocking smile curled the corner of her lips, and while fighting, she calmly mocked Rin.
"Still not giving up? Is a 'female gorilla' like you, who only knows how to use her fists, really a genius of magecraft?"
"Huh? 'Female gorilla'? You bastard, you're dead. Innocentius, kill her for me!"
Just during the fight, Rin had forced Lorelei to the vicinity of the jewel she had secretly thrown down earlier.
Roar!
A huge fire giant, at Rin's shout, appeared roaring behind Lorelei, raising a huge flaming cross and smashing it down toward Lorelei.
Feeling the high temperature coming from behind, Lorelei turned around without hesitation and drew the riding crop stuck at her side waist.
A huge gust of wind, following the swing of Lorelei's riding crop, converged into a wind bullet and collided with the Innocentius!
Boom!
Rin watched the explosion caused by the collision between the Innocentius and the wind bullets, not daring to be careless as she stood her ground, gathering starlight.
The massive explosion caused the surrounding people to instinctively move further back, giving Rin and Lorelei even more space for their battle.
Kayneth, who had been nervously watching the duel between the two, took this opportunity to ask Zelretch.
"Lord Zelretch, what is your take on this?"
"Rin is no match for that girl Lorelei. Once they enter a battle of magecraft, if Rin doesn't have a trump card, she will soon be defeated by her."
Hearing Zelretch's answer, Kayneth turned his head unwillingly toward Tohsaka Rin, who was gathering starlight on the field. 'Go for it! Rin, I believe that the little girl who played us all for fools back then won't lose like this!'
At this moment, affected by the daylight, Rin's starlight gathering was noticeably slower than usual. Finally, at the last moment as the dust settled, she entered Starlight Mode.
"Starlight Mode, Light Wing Deployment!"
Lorelei emerged from the dust. Seeing Rin floating in the air, she nimbly dodged the starlight and, with the help of wind magecraft, leapt up to the same height in the sky.
"Impressive magecraft, but not enough—Wail!"
A massive storm appeared, with wind power comparable to a Category 17 maritime typhoon, gushing out from the Magic Circle in front of Lorelei. It blew Rin away the instant it made contact.
Fujino, still some distance from the battlefield, saw Rin being knocked away. A rainbow light flashed in her eyes as she activated her Mystic Eyes of Distortion toward Lorelei.
Lorelei, having dodged Fujino's attack, was furious. She never expected anyone would dare to interfere with this duel and let out an angry roar.
"Crush them!—Wailing Wind!"
The gale changed direction and swept toward Sakura and Fujino in the distance.
Rin, blown away by the gale, casually tossed aside the gem dust that had shattered while blocking Lorelei's attack. She anxiously flew toward Sakura and Fujino. Detecting the reaction of distorted air just now, Rin easily recognized that the strike was the Mystic Eyes of Distortion.
While Sakura and Fujino were struggling to resist Lorelei's attack, Rin finally arrived. Realizing she was in the wrong, Rin charged straight into the range of Lorelei's magecraft to tank the attack. Enduring the intense pain, she made a gesture toward Lorelei.
Lorelei stopped her magecraft and approached Tohsaka Rin. Looking at Rin, who was kneeling on the ground clutching her stomach and chest while coughing up blood, she asked with a frown of confusion.
"Why?"
"Cough, these are my sister and disciple. Please forgive their unintentional actions."
Lorelei turned her head away in a tsundere manner.
"Boring emotions. Now that you've taken the Wailing Wind head-on, you've lost the ability to resist. I'll allow you to rest for a day before we fight again."
Rin hadn't expected Lorelei's magecraft to bypass the body's surface and attack the internal organs directly. Feeling that her organs were in tatters and she was only hanging on by a thread through magical energy, Rin stubbornly shook her head.
"No need. It was Fujino who interfered in the duel first, so it's only fair I took a hit from you. I can still fight. water of life!"
A massive amount of magical energy was converted from Rin's mage circuits. A glob of clear water appeared above Rin's head and drenched her.
Lorelei nodded as she watched Rin recover and stand up again, feeling a sense of recognition for her. However, she was somewhat puzzled by the cost of this magecraft.
However, if Lorelei knew the price of Rin's magecraft, it probably wouldn't be recognition, but a full-effort attempt to kill her. The water of life was the technique of Vasilisa, the leader of the Annihilatus in the A Certain Magical Index World. While it was just a mysterious and powerful magic in that world, in the Type-Moon World, due to the distortion of the magecraft base and Rin's modifications, it had not only become a one-time magecraft requiring immense magical energy but also carried a price: with each use, the person drenched in the water of life would gradually become a Dead Apostle, and their heart would be twisted into that of a murderous fiend!
Rin suppressed the bloodlust rising in her heart. Feeling the emptiness in her mage circuits, she spoke to the anxious Sakura and Fujino nearby.
"You two, no matter what happens to me, you are not allowed to interfere again. Do you understand!?"
Sakura and Fujino, who had just exhausted themselves to resist Lorelei's magecraft for a brief moment, supported each other as they stood up. Regretting their weakness, they glared at Lorelei, only nodding unwillingly when they sensed the impatience in Rin's eyes.
"Alright, let's settle this in one strike."
"Hmph. Tohsaka Rin, regardless of the outcome, I, Barthomeloi Lorelei, acknowledge you."
Rin and Lorelei rose into the sky again, facing off once more.
At this moment, Rin used the command spells on her hand to establish a mental link with Da Vinci back in Japan.
"Da Vinci, I need to use the Inherent Reality. Can I use it now?"
"Whoa! Rin, what kind of enemy did you run into that you need to use that!?"
"Stop rambling, Da Vinci. Just tell me if I can use it."
The Zenjou Residence in the suburbs of Fuyuki City—now called the Tohsaka Annex—had been bought from the Zenjō family by Tohsaka Tokiomi after the Fourth Holy Grail War. Rin, Touko, and Da Vinci had converted it into a magecraft workshop over the past few years. Receiving Rin's communication, Da Vinci looked at the massive apparatus beside her, hesitated for a moment, and then replied via the contract.
"Perhaps, should, possibly... no problem."
Rin looked at the increasingly impatient Lorelei across from her and spoke irritably to Da Vinci through the contract.
"Da Vinci—! I need a definite answer!"
"Ah! Rin, it's not like you don't know. After this device was built, it's only been used once and only lasted for three minutes. I don't know either, but it should definitely be fine for a short time."
"Fine for a short time, then? Da Vinci, link!"
"Well, since you've decided, Rin, then of course... OK!"
Da Vinci flipped the switch. Magical energy from the furnace instantly flooded the apparatus. Then, as the machine started up, Da Vinci stepped inside. The soul fragment of the Winter Saintess within the apparatus also emitted a brilliant light.
Feeling the steady stream of magical energy coming through the contract, Rin smiled slightly.'System—cooperate with me, let's begin!'
"Infinite Phase - Demon God's Sanctuary!"
