Lorelei looked curiously at the unfamiliar street. Under the bright starry sky, a row of massive windmills stood beside the empty modern street.
Lorelei turned around to see Rin, who had suddenly appeared behind her.
"An Inherent Reality? Is this your trump card? I'm quite curious how you, a human, can use magecraft of this level."
After saying that, Lorelei focused magical energy into her eyes and immediately saw through the mirage obscuring the command spells on Rin's left hand.
"Remote magical energy transmission! Is it a Servant from the Holy Grail War? Then those on your hand must be command spells. Although I don't know how you did it, it's meaningless—Wail!"
"As expected, it's this move again."
The violent storm reappeared, completely swallowing Rin.
Lorelei watched Rin being swallowed by the storm, then stopped her magecraft in confusion. She looked around warily, muttering to herself.
"What exactly is the effect of Tohsaka Rin's Inherent Reality?"
"The effect is, of course—Divine Punishment!"
A girl dressed strangely with a cross hanging from her tongue jumped down from a nearby building holding a massive hammer, landing in front of Lorelei. The newcomer was Tohsaka Rin, who had transformed into Vento of the Front with the help of the Inherent Reality.
Through the new 'Memory' function opened by the system in recent years as a mental image, combined with the device Da Vinci researched that could activate the Winter Saintess's soul fragment, Da Vinci was able to feed back a large amount of magical energy to Rin via the contract after obtaining it. Thus, the Inherent Reality 'Infinite Phase - Demon God's Sanctuary' was manifested in this world for the first time.
Ugh!
Lorelei clutched her head in pain, kneeling on one knee as she stared intently at Vento of the Front. Although her appearance had changed, Lorelei could still tell from the expression on Vento's face that this person was indeed Rin.
"Lorelei, admit defeat."
Lorelei endured the intense headache and quickly thought of a strategy. 'What kind of technique is this? Is it the effect of this Inherent Reality? No, if that were the case, I should have been affected the moment I entered it. Wait! This technique only started working after Rin changed into her current form.'
Tohsaka Rin, transformed into Vento of the Front, looked at the weakened Lorelei kneeling before her and raised her hammer, preparing to deliver the final blow.
Just as the hammer was about to strike Lorelei's back, a gust of violent wind erupted from Lorelei, forcing Vento of the Front back.
"I see! You deliberately took on this appearance in this transformation, didn't you? The goal was to make me feel hostility toward you."
Rin looked at Lorelei and curled her lip. 'You think I wanted to look like this? This is just how Vento of the Front dresses. Uh! I guess I am Vento of the Front right now.'
While Rin was distracted, Lorelei took the opportunity to raise her hands, and a massive Magic Circle expanded with her at the center.
"Submit!"
Dozens of massive tornadoes, like docile giant pythons, coiled around Lorelei.
Rin narrowed her eyes, staring at Lorelei floating in the air protected by dozens of tornadoes. She swung her hammer forcefully. With each swing, massive air masses, like blunt instruments, collided with Lorelei's tornadoes.
As Rin attacked, the 'pythons' came to life. Some began to roar and charge at Rin, while others showed their fury, picking up huge amounts of debris to form a wall protecting Lorelei.
Vento of the Front swung her hammer, sending out one "Air Blunt Instrument" after another to constantly knock away the tornadoes. Using the ruined buildings, she charged toward Lorelei in mid-air. 'I'm still too weak. If it were the original Vento of the Front, she would have stripped Lorelei of her consciousness the moment she deployed the Divine Punishment technique.'
The system's so-called Memory function was a feature that manifested battle scenes of magicians from the A Certain Magical Index World, allowing Rin to learn by watching these magicians fight.
Because Rin had been busy traveling the world looking for catalysts and conducting new research, even though she could barely recreate Vento of the Front with the system's help, she lacked a deep understanding of the techniques. Rin could only use these techniques mechanically. Combined with the limitations of her own strength, the Vento of the Front she transformed into couldn't even exert half of her true combat power.
Lorelei watched Vento of the Front rapidly approaching her and also had no way to respond. Although she possessed almost the strongest mage circuits among Magi, after several consecutive large-scale spells, she was now struggling even to control the tornadoes and didn't have enough magical energy for any other countermeasures.
What Rin didn't know was that back in Fuyuki City, Da Vinci was trembling as she watched the pipes around her constantly bursting.
'Rin, I can't hold on anymore! It's going to explode!'
Lorelei looked despairingly at Vento of the Front, who was swinging the hammer toward her. 'Am I going to lose?'
Boom! Da Vinci's equipment could no longer hold out.
Suddenly, the scene shifted instantly from Academy City under the night sky to the sunny El-Melloi Manor.
Tohsaka Rin stood awkwardly with her hand raised, looking at Lorelei in front of her.
"The weather is nice today!"
"Is that so? Go to... Ugh!"
Before Lorelei could activate her magecraft again, Rin acted quickly. She took a step forward, jumped into a scissor kick, and locked Lorelei's neck. As they both fell to the ground, she forcefully pinned Lorelei's right arm.
Lorelei struggled with her left hand against Rin's leg to give herself breathing room. At the same time, she noticed the crowd starting to gather around them from the corner of her eye. In a fit of rage and embarrassment, Lorelei made a decision even she hadn't expected: she opened her mouth and bit down on Rin's smooth thigh at the absolute territory.
"Ah! You're actually biting! Let go!"
"I won't bite, you let go of me firtht."
Feeling the pain from her thigh, Rin's anger also flared up. She bit down on Lorelei's fair forearm in return.
Zelretch, who was the first to approach, held his forehead. He looked with a headache at the two genius girls brawling on the ground like little girls. He took off his cloak and threw it over them to cover their clothes, which had been torn during the battle.
"Alright, separate. Mind your appearances. This duel ends here!"
Rin and Lorelei released each other at the same time, glared at one another, and both huffed, "Hmph!"
The two then separated, lowering their heads in embarrassment as they huddled under Zelretch's cloak. They remained like that until, under the cover of the mercury maids sent by Kayneth, they entered the castle to wash up and change.
In the spacious main bathroom of the castle, Rin leaned comfortably against the edge of the pool, looking up at the ceiling. Nearby, Fujino and Sakura, whose clothes were in tatters from Lorelei's earlier attack, stared hostilely at Lorelei, who was sitting next to Rin.
"Tohsaka Rin, let's call it a draw this time! As someone who fought me to a standstill, I allow you to proudly proclaim your achievement to the magecraft world!"
Rin turned her head and saw Lorelei's fair thigh nearby. She opened her mouth slightly, hesitated for a long time, but ultimately didn't bite.
Lorelei, who had her head lowered, saw Rin staring at her thigh with her mouth opening and closing. She shyly pulled her bath towel down a bit.
"Hey, there's no need to be so petty! I just bit you once! Didn't you bite me back?"
Rin turned her head away and rubbed the aching wound on her thigh, curling her lip. 'If I could beat you, you'd be waiting to be bitten to death by me today! Hmph!'
