The Magic Guild of Female Supremacy: Contracted as an SSS-Rank Mage's 'Mana Battery' - Chapter 13 & 14
Chapter 13
As payment for saving Silvia from her rampage, I fell unconscious and sank into a comatose state for several days.
During that time, Silvia apparently cared for me devotedly. When Fiona told me that the normally arrogant Silvia had fussed over me so diligently, I honestly couldn’t believe it.
When I awoke, the first thing I saw was Lunaria’s gentle jade eyes peering down at me with worry.
“Yuuto-san! Thank goodness… truly, thank goodness…!”
Lunaria squeezed my hand tightly, tears brimming in her eyes.
Silvia watched from a short distance away, her expression one of relief. The slight redness around her eyes was probably from lack of sleep.
According to Lunaria’s diagnosis, my magical power had undergone a qualitative change.
“Yuuto-san’s magical power has increased in purity and… there’s a possibility that a new characteristic has manifested—one that amplifies the abilities of others.”
(Amplifies… others’ abilities? What does that even mean?)
As I tilted my head in confusion, Lunaria made a serious proposal.
“To awaken you fully and stabilize this new power, might I employ my special healing technique? It would require… that is… quite an intense kiss and deep physical contact.”
Lunaria’s face flushed as she gazed up at me with hopeful eyes.
At her words, I saw Silvia’s eyebrow twitch.
(Intense kiss and deep physical contact… gulp…)
There was no reason to refuse.
With Silvia watching—or rather, glaring—Lunaria’s “special treatment” began.
She leaned softly against me, releasing a sweet fragrance, pressing her ample bosom against my chest.
Then, gently yet deeply, she kissed my lips.
Unlike Silvia’s kisses, this one enveloped me in warmth while carrying an undeniably sensual sweetness.
Lunaria’s tongue gently explored the inside of my mouth, and I felt her magical power resonate with mine.
A sensation like new strength welling up from the depths of my being.
I felt it become far more stable and powerful than before.
After that long, long kiss ended, I was completely revitalized.
“Yuuto-san, how do you feel? Your magical flow should be much improved.”
Lunaria smiled contentedly, a thin sheen of sweat on her forehead.
“Thank you, Lunaria. I feel incredibly good.”
As I expressed my gratitude, Silvia interjected sharply.
“Tch. How long do you plan to stay tangled together? Yuuto, we’re testing your new power.”
Silvia sounded irritable, though she clearly felt relief at my recovery.
The verification of my new magical characteristic began immediately.
Fiona and Eleanor joined in, and I took turns supplying magical power to each heroine via kiss.
Then something remarkable occurred.
The heroines who received my magical power experienced dramatic temporary enhancements to their signature magic and techniques.
Fiona’s short-sword work became too fast to track. Eleanor’s sword strikes gained enough force to shatter stone. Lunaria’s healing magic displayed miracles—instantly mending even grievous, near-fatal wounds. And Silvia’s offensive spells reached a level of destruction that resembled natural disasters.
“This is… an incredible power…!”
Even Silvia couldn’t hide her excitement.
My magical power had acquired a new characteristic—not merely supplying power, but “amplifying” others’ abilities.
This elevated my strategic value even further.
But it also meant I’d become an easier target for those seeking to exploit this power.
Then one day, Fiona pulled me aside with a proposal.
“Yuuto, I picked up some pretty risky intel. The rival guild seems to be plotting something again. So, um… wanna do some dangerous undercover investigation with me? Just the two of us—like a secret date!”
Fiona’s aquamarine eyes glimmered mischievously.
Chapter 14
The emergence of my magical power’s “amplification” characteristic was kept as top-secret within the guild.
Yet somehow—whether through information leaks or mere coincidence—the rival guild began showing suspicious activity once more.
It was Fiona Bergamot, the guild’s information broker, who uncovered this intel.
She asked me to cooperate in an undercover investigation of that rival guild. Naturally, just the two of us.
“This undercover mission is pretty high-risk. I think with your new power and my information-gathering ability, we can pull it off… what do you say?”
Fiona’s expression showed slight anxiety, but curiosity and a sense of adventure burned in her eyes.
I wanted to protect her. I wanted to prevent the rival guild’s scheme. I agreed to her request.
Silvia and the others… would remain in the dark, of course. I didn’t even want to imagine what they’d say if they found out.
On the day of the infiltration, Fiona and I met out of sight and prepared our disguises carefully.
Fiona wore the quiet, refined appearance of a traveling performer rather than her usual energetic look. I dressed as an ordinary peddler.
(Is this really going to work…?)
Despite some anxiety, I followed Fiona’s lead to a seedy bar where rival guild associates were said to frequent often.
The bar was filled with rough-looking characters, and my throat went dry with tension.
“It’s okay, Yuuto. I’m here with you.”
Fiona gently squeezed my hand and smiled reassuringly.
She wielded her natural communication skills and information-gathering expertise to expertly extract intel from the bar patrons.
I focused on guarding her, and occasionally—hidden behind her glass—I’d steal a kiss to supply her magical power, sharpening her senses.
With each kiss, Fiona’s ears flushed red, though her expression showed wonder at the effect.
(This really feels like a date… thrilling, but still…)
Fortunately, our disguises held. Fiona successfully obtained several crucial pieces of information.
Apparently, the rival guild had acquired designs for an ancient, powerful weapon and planned to restore it.
But we nearly got caught by what appeared to be an enemy executive.
A desperate pinch.
Yet Fiona’s quick thinking, combined with the physical enhancement from the magical power I immediately supplied, allowed us to slip away.
After completing the undercover operation, Fiona and I decided to celebrate quietly in a back alley on our way back to the hideout.
She offered me a sweet pastry she’d bought from a nearby shop.
“Yuuto, thank you so much for today. I definitely would’ve failed without you.”
Fiona conveyed heartfelt gratitude.
Her sincere words warmed my chest.
“And, um… today, you were really cool.”
Fiona’s face reddened as she gazed at me with glistening eyes.
Then she nestled her face against my chest and whispered in a small voice.
“I… I like you, Yuuto.”
A straightforward confession.
I wanted to answer her feelings.
I wrapped my arm around her shoulders and pressed my lips to her small mouth—pouring in gratitude and something deeper than friendship.
Fiona’s eyes widened in surprise, but she quickly closed them with a dreamy expression, accepting my kiss.
Sweet, slightly bittersweet—our secret kiss shared by no one else.
From that night onward, our relationship grew more intimate.
However, the information about the rival guild’s ancient weapon would soon develop into a crisis that shook the entire guild.
Several days later, the Magical Guild Federation announced the year’s “Guild Warfare Tournament”—a major event where guilds competed, risking their honor and rewards.
And my “magical amplification ability” would become the tournament’s greatest point of interest.
