Sona was known for always being calm and collected, praised for her intellect.
She was currently playing chess with her Queen Tsubaki. Tsubaki had her hair parted in the front and the rest of the hair was tied into a high ponytail.
Her most unique feature was her beautiful heterochromatic eyes.
Currently, she had a frustrated expression as she wondered what to do. Every move she could imagine lead her to a single conclusion!
Defeat!
"What's wrong Sona? You usually never bully me like this."
Sona neither agreed nor denied the accusation, She calmly sipped her tea. "I'm just trying to sharpen your skills Tsubaki."
"Yeah, right." She rolled her eyes, "Now tell me the real reason."
Sona pushed her glasses up as her face turned serious, "I can't contact Reya... She isn't answering me and I can't even locate her location using the devil piece."
Tsubaki who was placing her chess piece down suddenly paused and gasped in shock, "Then why are you just sitting here!?" She slammed her hand on the table and stood up.
The chessboard fell and the pieces scattered on the floor.
"Calm down, I've already contacted my sister." The chessboard flew back to its original place and the pieces flew back onto it one by one.
To her, it was better to call for immediate support rather than go on a fruitless goose chase. The longer she delayed the more the chances of Reya being harmed.
This was the difference between her and Rias, had this happened to one of Rias's peerage members she would be searching around aimlessly.
That was who Sona was, A decisive leader!
This calmed Tsubaki, "Do the others know yet?"
"No, but I'll inform them when the Maou arrives." She was just like that, not even casually addressing her own sister unless alone with her.
Tsubaki shook her head and sat down but her anxiety was revealed by her constant tapping on the floor using her foot.
An uncomfortable silence ensued before finally a blue magic circle appeared. Out of it, a figure showed up in a green dress, her hair was styled into twin-tails with pink ribbons.
She was short in height and looked cute but her current expression was solemn. This even caused Sona to be slightly nervous on the inside, she would never admit it but whenever she saw Serafall like that, she would truly admire her.
Her current demeanor was that of a true Maou.
When Serafall heard what Sona said her face immediately sank and she came here on short notice.
If a Peerage Master suddenly loses contact with their members it could only be due to two reasons.
First, The member was in a different dimension or an isolated space.
Second... The member was dead.
Serafall didn't immediately talk to Sona but closed her eyes and spread her senses throughout the whole city. It took her less than a second to do so.
She stayed like that for 10 minutes.
She opened her eyes and said to Sona who had already called her peerage, "Follow me, I've found her."
Sona couldn't help but nod shakily, Serafall, Her Sister, one of the four Maou's, had a grim voice, unlike her usual bubbly self.
A large magic circle appeared and all of them disappeared from there.
If anyone walked into the empty student council room they would be able to feel the heavy atmosphere.
***
Ryu's House.
In the living room, a magic circle appeared and the empty house was now filled with a crowd.
"REYAAAAA!" Tsubaki's scream cut through everyone's ears and they looked in the direction her trembling finger pointed.
In the living room was a coffee table and on it was head. Blood was constantly dripping down the edge of the table.
Reya had a weird but confusing expression as if she too was confused by what had happened.
Sona's legs started shaking and she dropped to the ground, "...Reya." She muttered soundlessly.
Her peerage members looked at the scene in anger and shock, for some, it was too much to handle, and went outside the door. A few vomited after leaving.
Serafall silently watched all of this happen. Her gaze then turned to her precious little sister who was on the ground on her knees, her hands were trembling and tears dripped down her cheeks.
Serafall's eyes turned bloodshot and she gritted her teeth, endless killing intent radiated from her body.
SHE WOULD ABSOLUTELY KILL WHOEVER DID THIS!
***
The Occult Research club had a serious but heavy atmosphere.
On the couch was a blonde man, he was Riser, the fiance of Rias Gremory.
Rias was sitting next to him and Riser's hand rested on her thigh which caused disgust and anger to flash through her eyes.
Just like that Issei and Riser got into an argument as the situation started heating up, Suddenly a silver magical circle appeared and a busty silver-haired maid appeared from within it.
Her beauty was a sight to behold.
She was Grayfia Lucifige.
She started soothing the situation and came out with a solution.
"Rias-sama, How about we hold the Rating Game after a week?" Riser was demanding for it to be tomorrow and this was the best she could do for her husband's sister.
Rias readily agreed and hyped her peerage up.
Grayfia nodded and turned towards Riser, "It has been decided then. The Rating Game shall be held a wee-" Suddenly her expression changed and sweat dripped down her forehead.
Heavy pressure descended from noticeably nowhere.
Most of Rias's peerage was on the ground on their knees including Rias and Riser had an expression of disbelief as he struggled on one knee.
Grayfia knew whose aura this was and this caused her worry to grow infinitely.
Who could have caused the lively bubbly magical girl to rage like this!?
'Did something happen to Sona?' Raising her aura she canceled the pressure in the air which allowed the rest of the people to sigh in relief.
"...W-what just h-happened?" Issei stuttered and looked around.
Everyone was silent and looked at Grayfia.
Grayfia looked at them and slowly said, "Maou Serafall Leviathan..."
Everyone's expression changed besides Issei who was still perplexed by the situation.
Grayfia disappeared from there immediately and an awkward silence permeated the Occult Research Club.
Riser got up and coughed awkwardly, he dusted the side of his collar and said, "Riser shall come at another time, for Riser believes you have more important stuff to do at the moment."
With that, an orange magic circle appeared and he disappeared.
Riad got out of her stupor and yelled worriedly, "Sona!" She dashed to the Student Council Room but found out that it was empty.
She could only return and walk in circles in the Occult Research Club nervously. Issei was still confused about everything.
"B-Buchou." He called out meekly and Rias turned her head towards him and explained.
"Sona's sister, Serafall Leviathan is one of the four Maou's of the Underworld and also known as the strongest female devil," Rias sat down and held her head with her hand. "There can only be one reason for her to grow so mad and that is... Something has happened to Sona!"
The situation's seriousness finally settled in Issei's mind. Unknowingly he called out to Ddraig, The Heavenly Dragon sealed in his arm.
But Ddraig's response only caused his head to spin more.
[Be careful from now on Partner... I feel an ominous premonition arise in my heart.]
