Re:Zero All Sins

Subaru was sleeping, as his mind dripted as he arrived in the hanging garden as he looked at all the witch waiting for him

Subaru walked up too the table, as he sat down. "I guess we will start the training".

Echidna smiles looking at him as he spoke. "I was already going to tech you the 6 Elements before this, but now todys we will learn the basics".

Daphne then spoke her golden eyes meet Subaru. "Also Darling You got New skill or will in 3 2 1".

Ding!

[Skill Acquired: Witch Lie]

Subaru raised an eyebrow at the notification as he read through the skill description in his mind.

[Witch Lie – Allows the user to weave perfect falsehoods that even high-level detection abilities cannot perceive. However, if the lie is contradicted by reality too soon, it will backlash against the user.]

Subaru gulped. "Oh great, a skill that turns me into a walking scam artist. Just what I needed."

Pandora giggled in his mind. "Oh Subaru, you already deceive so well~ Consider this a little upgrade."

Carmilla whispered. "P-please don't use it too much, lies can hurt..."

Subaru shook his head and focused back on Echidna. "Alright, let's start with magic training. I'd rather not get scammed by my own skill."

Echidna smirked. "Good. We will begin with an advanced understanding of the six elements. You already have a natural affinity for all of them, but control and application are entirely different matters."

She snapped her fingers, and suddenly, six glowing orbs appeared in front of Subaru, each representing Fire, Water, Earth, Wind, Yin, and Yang.

Echidna continued, "Since your affinity is universal, you need to train each element separately before we move on to fusion techniques."

Subaru sighed. "Why do I feel like this is going to hurt?"

Sekhmet yawned. "Mmm… probably."

Minerva crossed her arms. "Pain is just proof of growth. Now, let's begin!"

The next moment, Subaru felt his body get pulled into a magic simulation—he was standing in the middle of a battlefield, with a massive golem made of stone towering over him.

Echidna's voice rang out. "Lesson One: Adapt or Die."

Subaru groaned. "Yeah, of course it is."

The golem roared and swung its massive fist down at Subaru. His training had officially begun.

Sekhmet then looked at Echidna as she spoke. "Go easy on him ok, just because he can't die here, doesn't you can do Anything".

Carmilla then spoke. "Y-yes don't hurt Subaru".

Minerva then spoke. "Don't worry Me, Satella and Pandora can heal him".

Typhon then spoke looking at Subaru. "Good luck Big Brother".

Subaru moved out of the way from Golem, as he used [Invisible Providence] he grabbed a tree and moved out the way, as he jumped away as he looked at the other.

Subaru spoke too them. "Um can get a spell".

Pandora looked at him as he spoke. "Use your Video Game Knowledge Love~".

Subaru blinked at Pandora's words. "Video game knowledge…? Oh, I see where this is going."

He quickly sorted through his options. If this was a game-like scenario, then elemental weaknesses should apply. The golem was made of earth, which meant—

"Water or Wind magic should be effective!" Subaru realized.

He stretched out his hand and focused on the water element, feeling the energy flow through him. A small water sphere formed in his palm.

Daphne giggled. "Darling, that's cute, but you need more."

Minerva sighed. "Just throw it already, we'll fix you if you mess up!"

With no other choice, Subaru hurled the water sphere at the golem. The result? A small splash on its rocky surface.

Subaru groaned. "Yeah, figured that wouldn't work."

Echidna smirked. "You're thinking too small. Expand the spell."

Taking her advice, Subaru tried again, pouring more mana into the spell. This time, instead of a small water ball, a bursting wave of water surged forth, slamming into the golem's body and causing its rocky exterior to soften and crack.

Typhon cheered. "Nice one, Big Bro!"

Pandora clapped. "Oh~ You're learning quickly, Love!"

Echidna nodded approvingly. "Not bad. Now, combine it with Wind."

Subaru grinned. "Oh, I love this game."

As the golem recovered, Subaru switched his focus to Wind magic, generating a sharp gust around his arm. He then merged it with the lingering water spell, creating a slicing torrent of pressurized air and water.

"Take this! Aqua Slash!" Subaru shouted as he sent the combined spell hurtling toward the golem. The high-speed, water-infused wind blade tore through the golem's weakened form, causing it to collapse into rubble.

Subaru exhaled in relief. "Damn, that actually worked."

Echidna clapped her hands. "Well done. You're a fast learner, but this is only the beginning."

Subaru sighed, already feeling exhausted. "Yeah… I had a feeling you'd say that."

The witches all smiled as they prepared the next phase of his training.

Echidna then summoned a stronger Golum this ones made of steak, as Subaru's looked at the Golum

Subaru looked at Golem, as he pulled out his Knight Killer Dagger and Assassin Killer Dagger. "If the spells in this world are similar to spells in game I know them".

He charged a fire spell and charged at the Golum with a roar

Few minutes later.

Minerva, was healing him with the help of Satella and Pandora. As Sakhmet looked as she spoke lazy but kinda angry. "How did you manage to break 7 of your bones".

Subaru groaned as Minerva finished healing his ribs, still feeling the phantom pain of his failed attack. "Listen… I thought I had it under control!"

Echidna smirked, sipping her tea. "Oh? Please, do explain how setting yourself on fire was part of your master strategy."

Subaru sighed. "In RPGs, fire magic usually works well against flesh-based enemies, right? So, I figured if I infused my daggers with fire and went in close, I'd cut through it easily!"

Typhon tilted her head. "And?"

Subaru looked away. "And… I may have accidentally overcharged the fire spell… causing an explosion… while I was still holding my daggers."

Carmilla gasped. "Y-you made yourself explode?"

Satella shook her head, smiling softly. "Subaru, you need to pace yourself."

Minerva flicked his forehead. "Idiot! You can't just brute force magic!"

Pandora giggled. "At least you're entertaining, Love~"

Sekhmet yawned. "So? Gonna try again, or do we have to pick up your bones later?"

Subaru sat up, cracking his knuckles. "Oh, I'm definitely trying again. But this time… no explosions."

Echidna smirked. "We'll see about that."

The steak golem loomed over them once again, and Subaru prepared himself for round two.

Echidna then stopped then Steak Golem, as Carmilla went too him with a book that said Magic Basic. "I-i well help here".

Subaru took the book from Carmilla, giving her a grateful smile. "Thanks, Carmilla. I could really use some proper guidance instead of just winging it."

Carmilla blushed slightly, fidgeting with her hands. "Y-you need t-to learn the basics first… b-before trying anything advanced."

Echidna crossed her arms. "She's right, Subaru. No amount of video game knowledge will help if you don't understand how magic works here."

Subaru sighed and opened the book, skimming through the introduction. "Alright, alright. Let's see…"

Magic Basics:

Mana Flow: Understanding the movement of magic within the body.

Elemental Affinity: The strengths and weaknesses of the six elements.

Chanting & Intent: The balance between spoken incantations and sheer willpower.

Subaru frowned. "So, I actually do need to chant some spells?"

Pandora smiled, resting her chin on her hand. "Not necessarily, Love~. You can cast spells without chants if you master intent and visualization. But that takes time."

Sekhmet lazily waved a hand. "For now, just do it properly, yeah?"

Subaru grumbled but nodded. "Fine. I'll do it step by step."

Echidna smirked. "Good. Then let's start with the most fundamental part—controlling your mana flow."

Satella then spoke looking at him. "Technically you don't have A Mana core you have witch core like us, that is how your ability gets there energy from".

Subaru blinked in surprise. "Wait, what? I have a Witch Core instead of a Mana Core?"

Echidna nodded, adjusting her glasses. "Indeed. While most people have a standard Mana Core that acts as a reservoir for magical energy, you, my dear Subaru, possess something far more unique—a Witch Core."

Satella's voice was soft but firm. "Your Witch Core functions differently. Instead of simply storing mana, it directly connects to the Authority you wield and fuels it using your emotions, desires, and instincts."

Minerva crossed her arms, frowning. "That's why you break your bones so easily! Your magic is more instinctual, but you don't know how to regulate it!"

Subaru scratched his head. "Okay… so basically, my magic is powered by emotions and instincts, but I don't have the proper control over it yet?"

Pandora giggled. "Exactly, Love~. If you don't manage your emotions properly, your power might go wild."

Sekhmet yawned. "You need to learn how to circulate your energy properly. Otherwise, you're just gonna burn out."

Carmilla shyly held up the book again. "T-this has meditation techniques t-to help w-with that…"

Subaru sighed, flipping through the pages. "Alright, I guess I have to start from square one."

Echidna smirked. "Don't worry, Subaru. By the time we're done, you'll be wielding your magic as easily as breathing."

Subaru was going to speak about how it didn't make sense but then he stopped. "Yeah that makes sense, stupidly large amount of sense".

Carmilla then spoke Looking at him. "We will help you control it".

Subaru looked at Carmilla as he patted her head. "You spoke with out stuttering this time, your getting better".

Carmilla's face turned bright red as she lowered her head shyly. "I-I didn't even notice…" she mumbled.

Minerva smirked, crossing her arms. "Looks like being around Subaru is actually helping you get more confident."

Satella gently placed a hand on Subaru's shoulder. "We'll all help you control your Witch Core. You're one of us now, after all."

Echidna flipped open another book. "Then let's begin. First, you need to feel your Witch Core and direct its energy properly."

Subaru sighed, stretching. "Alright, let's do this! Time to figure out how not to break my bones every time I use magic."

Pandora giggled. "Good luck, Love~."

With that, Subaru sat down and closed his eyes, ready to begin his training in earnest.

As Subaru closed his eyes, he focused inward, trying to sense this so-called "Witch Core." At first, all he felt was the usual flow of mana within him, but then, deeper within, there was something different—something vast and chaotic, yet oddly familiar.

Echidna's voice guided him. "Your Witch Core doesn't work like a normal mana core. It doesn't just generate energy—it connects you to the very concept of Authority itself."

Subaru furrowed his brows. "So… it's like an engine that fuels my Witch Powers?"

Sekhmet yawned, resting her head on her hand. "Mmm, something like that. But if you lose control… Boom."

Subaru's eye twitched. "That's not reassuring."

Minerva crossed her arms. "Don't worry, if you blow yourself up, we'll just put you back together again."

"Yeah, that doesn't make me feel better either!" Subaru groaned.

Pandora giggled. "Let's start simple. Try circulating your energy without using an ability. Just move it through your body."

Subaru took a deep breath and did as instructed. At first, it felt natural—like moving his own mana—but the moment he tapped into the Witch Core, it was like trying to control a raging river. The power surged unpredictably, nearly slipping from his grasp.

"Whoa, whoa—!" His body tensed as an overwhelming force built up inside him.

"Calm down," Satella said gently, placing a hand on his shoulder. "Don't fight it. Accept it."

Subaru swallowed and tried to ease his grip on the power, letting it flow naturally instead of forcing it. Slowly, the energy settled, spreading evenly throughout his body.

Ding!

[Witch Core Control (5%) – Beginner Level Achieved]

Echidna smiled. "Good. You're learning faster than expected."

Subaru wiped some sweat off his forehead. "That was just step one, wasn't it?"

Typhon grinned. "Yep! Now let's see if you can actually use it in a spell!"

Carmilla shyly handed him another book. "T-this has some basic spells you can t-try."

Subaru sighed, standing up. "Alright, round two. Let's see if I can use magic without breaking my bones this time."

Echidna smirked. "Let's hope so."

And with that, Subaru's real training began.

Few hours has passed

Ding!

[Witch Core Control (100%), skill upgrade - Advanced level Achieved]

Subaru Smirked as the world started too become blur. "So I ma walking up".

Echidna then spoke Looking at him. "I say one more hour so what do you wanna do in this hour".

Subaru though as he spoke. "Will just spend with you girls until I wake up".

Hearing that, the witches all reacted differently. Echidna smirked, pleased with his answer, while Carmilla blushed and fidgeted. Minerva crossed her arms, trying to act indifferent, but there was a small smile on her face. Satella simply looked at him with a warmth in her eyes, while Pandora chuckled playfully.

"Spending time with us, huh?" Echidna leaned in. "You've certainly become more comfortable around us."

Subaru shrugged. "At this point, I don't even question things anymore." He stretched his arms. "Alright, so what do we do? Tea party? Training? Storytime?"

Typhon grinned. "Storytime sounds fun! Tell us something from your world!"

Subaru thought for a moment before nodding. "Alright. How about I tell you all about a hero from my world?"

The witches gathered around as he began. "There was once a man named Iron Man..."

As he told them about the armored hero, they listened with varying levels of interest. Echidna seemed fascinated by the technology, already pondering its magical applications. Minerva scoffed at the idea of a hero relying on machines but admitted he sounded interesting. Typhon and Pandora were thoroughly entertained, while Carmilla clung to every word with awe.

Satella, however, just watched him with a smile, content to simply listen to his voice.

Before long, Subaru felt his body pulling away, reality reclaiming him.

"Looks like I'm waking up," he muttered.

Satella reached out, placing a hand on his cheek. "Come back soon, Subaru."

He gave her a small smile. "I will."

With that, his consciousness faded from the Witch's Tea Party, and he returned to the waking world.

Pandora then spoke seeing him wake up, as she joked. "Why don't you give us a kiss before your leave".

Subaru looked at her as he thought Ans spoke. "Sure".

Pandora, Echidna and Sekhmet was take back, Both Satella and Carmilla then started to blush, Minerva and Daphne just looked at Eachother and smirked.

Typhone then spoke. "And I want a head pat big Brother"?

Subaru chuckled, amused by their reactions. "Alright, alright," he said, ruffling Typhon's hair first. "There's your head pat, little sis."

Typhon grinned happily, leaning into his touch.

Then, he turned toward Pandora, who had made the initial joke. "Well, you asked for it," he said, leaning in.

Pandora, still slightly surprised, kept her confident smirk as she let Subaru plant a small kiss on her cheek. "Ara~ You actually did it."

Echidna, regaining her composure, adjusted her expression. "I suppose I shouldn't be surprised. You're reckless enough to do something like this without hesitation."

Subaru shrugged. "You all mean a lot to me. If a simple kiss or head pat makes you happy, then why not?"

Sekhmet yawned. "Hah... if you're offering, I wouldn't mind one either~"

Subaru rolled his eyes but leaned down and kissed her forehead. "Happy now, lazy witch?"

Sekhmet smirked, satisfied. "Mmm, not bad."

Minerva crossed her arms, still smirking. "You better remember this moment next time you need healing, Subaru."

Satella and Carmilla, still blushing, avoided eye contact, while Daphne chuckled in amusement.

Subaru stretched as he felt reality pulling him away again. "Well, see you all next time."

And with that, he woke up.
