Chapter 660 - 660: [660] : Grandmother Found Out After All

At that same moment, in the corridor just inside the old schoolhouse's entrance, Kuroka stood with her cheeks cupped in her hands, narrowing her eyes at the two figures who had just walked in.

"I thought you'd hold out a bit longer. Didn't expect you'd give in so fast and skip straight to joining your daughter on the battlefield."

These words were naturally directed at Venelana.

After all, Kuroka had known about Bokue and Venelana's relationship for quite some time. They'd just been very good at hiding it—probably terrified Rias would spontaneously combust if she found out.

Yet not even two days had passed—barely a day and a half in the Underworld, to be precise—and things had already progressed to the point where she could be brought along to tonight's "bath party"?

That clearly meant everything had been laid bare while they were in the Underworld.

But facing the cat-eared girl's teasing, Venelana simply smiled softly.

"While I'm grateful for Miss Kuroka's help in keeping things hidden, at the end of the day, I'm still a woman. Love and desire... such selfish emotions were never meant to stay bottled up forever."

"Besides, even if you manage to hide something temporarily, eventually it will all come bursting out. So isn't it better to find the right moment and just come clean with it?"

The elegant woman tilted her head gently as she finished.

Kuroka continued squinting, pausing for two or three seconds before finally clicking her tongue.

"Tsk tsk, you devils really know how to play... Alright, alright, enough dwelling on this. Hurry up and get inside—everyone else is already here."

"Mm-hmm~"

Venelana smiled once more, then followed Bokue and Kuroka toward the bathroom.

With that, the entrance hall of the old schoolhouse fell silent once again.

About five minutes passed—

Click.

The soft sound of a door latch being turned echoed through the entrance hall. The sliding door—firmly shut just a second ago—was suddenly pulled open from outside, revealing a narrow crack.

Then the entire door was silently pushed aside, and a small crown peeked in through the gap.

"Hmm~ No one here."

Runeas poked her head in like a burglar, looking left and right while muttering to herself.

Could it be they weren't actually having some secret celebration behind her back?

After all, a party would definitely be noisy. But from the doorway, the entire corridor was completely silent.

But if that was the case, what had Bokue and Venelana-chan come here for?

Unable to make sense of it, Runeas pondered for a moment before stepping inside anyway, beckoning behind her.

Chysis followed her in.

The gentle-featured, warmly elegant crimson single-ponytailed woman scanned the shoe rack by the entrance and let out a soft "hm."

"Bokue and Venelana-chan's shoes are here. It seems Lady Runeas didn't see wrong earlier. However..."

Splash—

But before Chysis could finish, a faint sound of water from the far end of the corridor—toward the stairs leading to the second floor—immediately caught both their attention.

Runeas instantly raised her head and followed the sound, listening carefully for a moment before turning back to Chysis beside her.

"Hey, Chysis-chan—did you just hear water coming from that corridor?"

"Yes, Lady Runeas. I heard it too."

Chysis nodded lightly.

"I knew it!"

Runeas's eyes lit up at the confirmation.

"Hmph hmph, they hid it well, but I caught them in the end... So they're having a secret celebration behind the back of me, the origin of the Gremory family? Well then, I simply must deliver some proper punishment..."

"Shh~"

Before the crown-wearing crimson twin-tailed devil girl could finish, Chysis quickly raised a finger to her lips, signaling her to keep her voice down.

After all, this was someone else's home. They'd snuck in without invitation—if they were discovered, things would be rather awkward.

At the very least, it would be embarrassing.

"Mm..."

Runeas also realized this point and nodded obediently, indicating she would stay quiet.

The two of them then crept from the entrance toward the stairs at the end of the corridor, finally stopping before a door marked with the character for "Bath."

Because they could already hear the continuous sounds of splashing water from inside—identical to what they'd heard from the entrance.

And also... the voices of a young man and several girls.

"Alright, who's first today? I remember last night ended with Akeno-nee, right? So today should start with Asia. Come on."

"I-I'm coming..."

"Ready? Here we go."

"Okay... MMPH!!"

Through the wall, they heard the blonde girl's usual soft, gentle voice—innocent as a harmless little lamb—suddenly cut off by a sharp, high-pitched moan.

As if she'd been hit by some fierce attack, the blonde girl's voice became fragmented and broken.

"S-so amazing... ahh..."

From there, it seemed to enter full assault mode. The blonde girl—normally as docile as a lamb—had absolutely no way to fight back against the young man's ferocious onslaught. Soon only scattered words and fragments remained.

But this alone was enough to shock Runeas.

What did "so amazing" mean?

What... what exactly was happening in there??

A scalding blush instantly flooded the crimson twin-tailed girl's face.

But she couldn't leave anymore. The voices of the girls inside continued drifting out, as if possessed of some strange magic that compelled her to keep listening.

About ten minutes passed like this, quickly building toward the climax of the first movement.

"AHHHNNN!!!"

A climactic scream echoed from behind the door.

She knew her face must be red enough to drip blood right now. She didn't even dare turn to look at Chysis beside her.

What Runeas didn't know, however, was that at this very moment, Chysis beside her also had a faint blush on her cheeks. Her moist lips glistened as those hereditary emerald eyes sparkled with light.

What a vigorous young man... to make females produce such sounds so effortlessly...

And earlier, they'd seen Venelana come here too from their room upstairs. Which meant—

Hehe, this just got interesting.
