Sorry...

Achilles turned his eyes away from Sia and he used his hands to cover his face.

[What are you doing here?] He asked while trying his best not to let her see how he looked.

For some reason, he didn't want Sia to see him right now.

After all, he couldn't keep himself safe like she had asked him to. Failing to fulfill what she asked him to...made his heart feel terrible.

[...Are you...okay?] Sia arrived by his side before gently touching his face, forcing him to face her.

Achilles' skin was being healed back to normal so he looked very hideous at the moment.

[We're sorry...] The little elf muttered in a choking voice.

[What are you talking about?] Achilles held her cool hands as he asked in a puzzled manner.

[If we were here then-] Achilles held a finger in front of Sia's lips which made her stop talking.

[I'm fine, ok. We'll talk about this later. First, we need to kill the leader.]

Sia was about to say something else, but seeing his gentle eyes, she obediently nodded her head.

[Where are the others?] Achilles looked left and right. All he saw was a sea of flames and the occasional clashing sounds rang out from the distance.

[They're probably still dealing with the horde. We should let them handle it here and kill the leader.]

Achilles nodded slightly and prepared to move when Sia suddenly held his arm. She gave him a pill that was different from all the rest he had seen.

[What's this?] He tilted his head slightly.

[Swallow it. It's a hyper-regeneration pill, you should be back to how you looked before in no time.]

[Alright.]

Achilles took the pill from her hand and swallowed it without hesitation, the thought that she might have done something to the pill did not even cross his mind.

20 seconds after ingesting the pill, Achilles' skin started healing back at an even faster rate than before. Soon his entire body had returned to normal along with his hair.

[What kind of pill is this...?] He touched his face slightly while muttering in awe.

[We created them ourselves. There's only one of these left you know.] Sia touched her chest as she smiled happily seeing him recover.

[...Thank you.] Achilles' face became a warm and grateful smile.

[You're welcome.] Sia's ears turned red slightly as she looked away, then added after a moment. [We should go now.]

[Ok.]

The couple disappeared from where they were as they headed to the source behind this terrifying horde.

~~~~~~~~~~

Boom! Boom! Boom! Boom!

Thousands of crystal bullets pierced the Corrupted as some of them fell down, and the others continued advancing forward.

The abominations that managed to withstand the rain fire came in conflict with the three crystal golems. The latter used their massive strengths and chrysalis bodies to defend against a multitude of different attacks while smashing everything in their way.

Some of the monsters that bypassed the defense created by the golems sprinted at their full speed at two human figures in front of them.

One of the humans — a fox girl summoned a soul artifact in the shape of a spear and dashed forward.

A Corrupted that was similar to a slime raised its tentacles-like limb and shot forward, intending to pierce the girl apart.

The latter dodged the strike with elegance before a whirlwind started appearing at the tip of her spear.

She thrust the spear forward and the Corrupted instantly got turned into a puddle of slime.

She didn't get a chance to breathe before two more Corrupted jumped at her from the side.

Before they managed to get to her, the other human used her greatsword which was imbued with red flames, and slashed down violently.

The two Corrupted were dead instantly from the terrifying attack.

"Thanks." Mina said quietly before turning her gaze to the rest of the Corrupted.

"You're welcome. Although that may have been unnecessary when you're the famous Crystal Queen." Yuna commented in a slightly impressed tone.

Mina silently rolled her eyes at the nickname. Because of the way she fought using her crystal abilities, everyone had begun calling her by that nickname nowadays.

Although it had a nice ring to it, she was no queen, and being called like that all the time was very uncomfortable.

'How do big sis and Luna just deal with this all the time anyway?' The fox girl sighed with a hint of envy.

5 minutes later, most of the Corrupted had already been decimated by Mina and Luna due to their powerful abilities.

While the two thought they could finally relax for a second, two humans suddenly arrived in front of them which made their guard raise again.

When Mina saw that it was someone she knew, a sigh of relief escaped her breath, but soon her brows furrowed slightly.

'Big sis and...the guy who called himself Achilles?'

[Mina, what's the situation?] Sia's melodious voice reached her ears which made her snap out of her daze.
