Renner Lebrious heard the tremors surging from beneath the room where she slept.

As a member of the Middle Class’ Elite Ten, she was privileged to have her room on the topmost floor of the female dorm. Since there were only two girls among their ranks, they had the entire area to themselves, even though eight rooms remained untouched.

She wasn’t on good terms with her colleague, though, so they stayed at opposite sides—divided by the hallway that existed between them.

Usually, the night would be silent. Renner loved these moments when she got her beauty sleep. That was why she was so shaken by the commotion that abruptly knocked her awake.

‘What could that be…?’ Her mind trailed, and she grumbled internally.

The girl plopped herself out of bed and sluggishly moved to the door, smacking her lips. Since she was used to enjoying her sleep every night, Renner wasn’t completely awake.

Until—

BOOOOOOMMMM

—The grounds rumbled once more! The entire building trembled, and she was knocked off balance, falling on her butt.

“O-owww…” She groaned in a cute manner as she rubbed her behind.

Tiny sobs came out as she stood, wondering who could be so cruel as to cause her to suffer such shock in the middle of the night.

The rumble was enough to drive her completely awake though. Now, she simply wanted to figure out what was going on.

Renner was in her pajamas, so she had no qualms marching downstairs to reprimand whoever was responsible for her discomfort. Moving according to her instincts, she put on her flip-flops and swung her door open.

In front of her—yes, directly opposite her door—another door was open. It was that of another girl, one who shared a form of rivalry with her.

“Sia…?” Renner managed to mutter, seeing the more mature-looking lady in a negligee.The soft wooly fabric was lined in thin lace that subtly showed her body—her finely accentuated body—the opposite of Renner.

Sia gave a slight scoff as she stood at the entrance of her room, glaring at the plain pajamas Renner donned. Compared to her sultry outfit, the sight of the nightwear was nothing short of pathetic.

“W-what are you doing out here… wearing that…?” Renner added the last part as an afterthought.

Sia’s curves and ample bosoms oppressed her to the point that the Elite girl had to turn her eyes away. Sia noticed this and flashed a confident grin.

“Why else, those tremors… you felt them too, right?” Her voice was icy cold.

“As for my attire… we’re the only ones here, so it’s fine.”

As the only females in the Elite Ten, no one else was permitted to reach their floor. The vast, empty hallway was a testament to that fact.

“I-I see…” Renner mumbled.

BOOOOMMMMM!!!

The tremor occurred again, nearly pushing both girls to the floor, but they quickly regained their stance—refusing to be caught off guard again.

“What the heck is that? I swear, which retard is doing that?!” Sia hissed in frustration.

‘You’re speaking vulgarly…’ Renner wanted to correct her, but quickly cautioned herself, keeping those sentiments to herself.

She couldn’t say she wasn’t upset, though. The annoying tremors were getting on both their nerves, and before they knew it… both girls were walking side by side to check out the cause.

They made sure to carefully tread down the stairs, picking up their pace and reducing it as they deemed necessary.

As they descended the floors, Renner could see many slightly opened doors, and a bunch of students poking their heads out.

“R-Renner Lebrious and Sia Telmunt…?”

“W-what are they doing on this floor?”

“They’re not the ones at it downstairs?”“If it’s not them, then who?”

The last two sentences made Renner smile wryly, allowing why her juniors would think that to sink in.

Everyone in their Dorm—no, in the entire Middle Class—knew the strained relationship she had with Sia. They were sworn enemies/rivals. Sia previously held the position of Fourth Seat among the Elite Ten before Renner yanked it off after winning in another one of their battles.

Since then, their ranks were swapped. The current fourth-ranked knew that if she didn’t stay on her toes, though, Sia would reclaim her title. This bad blood of theirs made the two infamous for causing a racket, both in class and also within the confines of their Dorm.

They had engaged in several fights in the building and caused commotion which made everyone wary of crossing their paths.

That was why, when the other students felt the violent tremors, they thought the girls were at it again. It was a surprise to see that they weren’t the culprits, though.

The girls peeled their eyes through the little openings they had and watched the Elites walk side by side.

Sia’s appetizing body in her negligee.

Renner’s washboard body in her pajamas.

They headed down, obviously in foul moods, ready to deal with whoever was responsible for their discomfort.

The students silently cheered them on, happy to see that the girls were on the same side for once. Plus, they were going to put an end to a general menace—not constituting a menace themselves.

The hopeful, grateful watched the descent of their champions.

‘They’re looking at me so intently… are they comparing us? Why did Sia wear the negligee down? She could have changed to something more appropriate…’ Renner’s mind flew in multiple directions.

She was prettier than Sia and had a higher rank, but… the flat-chested girl couldn’t simply compete with her rival’s physique.

Perhaps there was hope for her in the far future… maybe…

BOOOOOOMMM!!

This time they felt the tremor surge through their bodies as it vibrated through the air. Renner ceased pointless thoughts, and so did Sia.

Their bodies shook violently, and they found themselves tumbling down the stairs which led to the ground floor.

As they fell, trying to control themselves with Magic, the girls heard something shatter—like glass, but not quite.

It was the noise of barriers breaking.

Renner and Sia, now at the bottom of the stairs, tumbled atop themselves, looked in the direction of the usually sparse ground hall… only to be met with the most unexpected sight ever!

—HORROR!
