And so, every day just keeps looping on like some kind of never-ending grind.

For the first two weeks, Eris has me doing cardio.

All. Day. Long!

But as I get rewarded with daily buffets of wyvern drumsticks and wyvern eggs, I'm not complaining! By the time evening rolls around and I'm limp like a soggy noodle, Eris pulls out this massive massage roller and starts rolling me flat like I'm a fresh catgirl shaped dough!

It feels so good, though. Like, criminally good!

I got addicted. Now it's my favorite evening ritual. Roll me, knead me, turn me into a perfectly tender Felicia-flavored mochi!

By week three, the training gets even crazier. The cardio doesn't go away (unfortunately), but now we start throwing in resistance workouts and weightlifting too.

But at least, our home gym is freaking legendary! Whatever weight I want, it's there. Every dumbbell is enchanted too! Just say the word and—bam!—it adjusts the weight automatically!

Alongside all that, I add swimming and balance training to my daily schedule.

Swimming is amazing, by the way. There's something oddly peaceful about gliding through water…

And on the other hand, those balance drills are totally my jam too! They are super easy to do and not exhausting at all! First, it's standing on one leg. Then handstands. Then walking on tightropes...

They may seems difficult at first, and I thought so too.

But turns out, no!

Because I have an amazing companion! My tail!

Hehe...

Thanks to my long, sleek, perfectly balanced tail, every balance drill is a breeze! These days, I somersault, climb trees, and parkour like a total beast! I don't even need Eris to hoist me onto the roof for stargazing anymore.

And now… exactly one month since training began...

It's time to check my stats!

"OH YEAAAAAAAAHHH!!!"

I leap into the air, both hands shooting skyward in pure ecstasy!

"Eris! 5.59 for real?! Is that legit?!"

"Hehe, totally real~" Eris grins, her smile brimming with pride. She even wipes a tear from her eye with her hand!

"Felicia, congrats. You're officially a D-rank adventurer now!"

"Haha! Oh yeahhh!!" My whole body vibrates with joy. My tail curls up stiff as an iron broom!

"We're celebrating tonight! We're eating tons of wyvern and cake!"

"Haha, four weeks of wyvern nonstop and you're still not sick of it?"

"Nope! Never! Wyvern is the best thing in the universe!"

Seriously.

Ever since I first tasted wyvern meat, I haven't craved any other kind!

It's just too damn delicious!

I swear, I could eat wyvern for life and never get bored!

Seeing me so hyped, Eris just laughs and gently pats my head.

"Hehe, Eris, I know you're hooked on wyvern too~"

"Obviously!" Eris nods with proud confidence.

"Alright," she continues, her tone turning serious. "Now it's time to test your physical prowess under your Demonic power!"

"Nn!"

I close my eyes, focus my mind, and start awakening the massive power slumbering in my mana core.

A while later, after a whole series of physical tests...

"Holy—!" Eris gasps, her face showing pure shock.

"What? How much? How much?!" I jump up, rushing toward Eris to peek at the results.

But Eris pushes me back, not letting me see!

Hmph!

Mean Eris! Always keeping secrets!

Then, she takes a deep breath, like she's trying to calm herself.

"Okay... Felicia, your new test results are…"

I fall silent, listening intently. My ears and tail stand straight up with anticipation.

"Oh my gosh…"

I hear the results and nearly topple backward.

31.25…

That's straight-up B-rank adventurer territory!

All it takes is a score above 20 to qualify for B-rank!

"This is unbelievable!" Eris exclaims. "This growth rate… are you even human anymore?! At first, I thought it'd take you at least a year to break past 20 points, even with the Devouring Core's help. But… just one month…"

"Hehe~!" I flash a wide, toothy grin.

By the way, it's time for a bold declaration!

"Eris! I'm catching up to you soon! Just you wait!"

After all… Eris is still an A-rank adventurer nyahahaha!

If I push just a bit harder and get my total score to 50, I'll hit A-rank too! And if I can achieve that, my original goal and dream—to be able to fight side by side with her—will finally come true!

"Alright," Eris nods. "No cardio today!"

"HECKKKKK YEAHHHHH!!!" I shout, bursting with excitement.

No cardio?! This is paradise!

I owe cardio for getting me this far… but, ugh, it still sucks ass! Time to move on to a fresher training program!

"So, what's on the menu today? Weights? Balance training?"

"Nope," Eris replies, her lips curling into a sly, mischievous grin. "Today, we're training in swordsmanship!"

___________________

With that, Eris rubs her storage ring.

Instantly, a cascade of wooden swords flies out from the ring—every shape, every size!

Rapiers? Check

Longswords? Check

Short swords? Check

Greatswords? Check

Even a massive Behemoth sword is in the mix!!

Thwack! Thwack! Thwack! Thwack!

One by one, the swords plunge into the ground in front of me, lining up in a perfect row like a military salute!

"Ooooh, swordsmanship training?!"

OHHHHH YEAAAAAAHHH!!!

Today is hands-down the best day ever! Because finally, I get to start doing some combat related exercises with Eris!

I eagerly grab a wooden rapier, gently gripping the hilt and lifting it.

This rapier is about a meter long, with a slender, slightly pointed blade. The leather-wrapped hilt feels light but sturdy. Though it's made of wood, the surface is polished smooth,complete with intricate grain patterns that make it look almost real.

I twirl it a few times in my hand, testing its balance.

It probably weighs around 2 kilograms!

The old me would've strained just to hold a 2-kilo sword. But the Felicia of today? This thing feels as light as a toothpick in my hand!

"Felicia," Eris says, "if I remember right, Alter already taught you some swordsmanship basics, didn't she?"

"Yup, totally!" I nod enthusiastically.

Alter had passed down three super-cool sword techniques to me!

First up: Di Ventara Sword art.

Second: Chaos Tempest Sword skills.
