Quadratic Element from Zero

The next day, after school in the afternoon, members of the Occult Research Department gathered in the department room.

However, it is a little different from before. There are still some people in this department today. They are people from the Kuo Academy Student Council, and Gemmon, where Rias is located.

The eponymous Sidi family.

The leader is the student council president Sona Sidi, who, like Rias, has a demon king brother, Sona's sister is also one of the four major demon kings, so the two

There is something special about the relationship between people...

"Cang Na, are all your people here?"

Looking at the members of the student council, Rias said, "If you miss it, then there will be no way for this competition..."

"Rias, you should worry about your side..."

Cang Na gave Rias a white look and said, "It seems that your chariots haven't arrived yet, what about that guy called Jiuzhong Qiye?"

"Seven nights...he will come soon..."

The corners of Rias' eyes twitched twice. She originally wanted to find an excuse to prolong her time, but she was seen through at a glance.

"yes……?"

Cang Na looked at Rias strangely. As a friend, she didn't know what Rias was thinking. She just said it casually, but it seemed that

Received some unexpected gains...

"Tick...tick..."

Time passed by second by second, and after ten minutes, the figure of Qiye appeared in the department.

"Ah, sorry Rias, I forgot to hand in yesterday's homework, and the teacher stayed for a long time to train..."

Qiye scratched the back of his head, swept everyone's eyes and stopped at Cana, and said, "Oh, this is the Canna that Rias often said, thank you very much.

Your help to Rias in the past, the first time we met, I was her chariot—Kuou Qiye..."

"Ah hello……"

Cang Na nodded, looked at Rias and said: "Everyone is here, let's go quickly, there is not much time until the start of the game..."

"I see……"

Rias nodded, and the magic power poured into the transfer circle in the room.

Following the Gremory family crest, the student council and the paranormal research department disappeared into the room.

What will greet them will be a new round of fierce battles, a grand event that belongs to the devil...

Chapter [-]: The Appearance of the Old Demon Sect

"Reached……?"

After the dazzling magic light disappeared, Qiye opened his squinted eyes.

In front of you is a wide space, thick pillars stand on the ground at a fixed distance, and the ground below... is also paved with slate...

Behind Qiye and others, there is a huge temple entrance. This temple, which is not damaged in the slightest, looks like it has just been built...

"Um...? Is this our position?"

Kiba Yuto frowned and said, "Why hasn't the referee announced the start yet?"

"It's weird..."

Rias frowned and said, "Everyone be careful..."

"Om..."

At this time, a magic circle appeared opposite the temple. It seems that this battle will be a close encounter... However, unlike what we imagined, there is not only one magic circle, and the sky is almost filled with magic circles in an instant. Surround Qiye and others in the center.

"...That's not the drawing of the Astati family!"

Hearing Rias's words, the long sword in Kiba Yuto's hand was unsheathed instantly, and the thunder and lightning in Himejima Akeno's hand also began to sizzle.

"...Although there is no complete commonality between each magic circle, but..."

Looking at the magic circle unfolding in the sky, Rias frowned and said, "...These guys are all demons...and if I remember correctly—"

Rias's body burst out with red arrogance, and her sharp gaze swept all around.

Immediately afterwards, a large group of demons appeared from the magic circle, and all of them exuded strong killing intent and hostility!

There is only one target, and that is Nanye and the others who are surrounded by...

The number of demons is astonishing, more than a hundred in just a few tens of seconds, and the number is still increasing...

Rias looked at these demons with sharp eyes and said, "From the perspective of the magic circle, these guys are some old demon kings who are loyal to the 'Bang of Calamities'..."

"I'm really curious, Rias... Could it be that you accidentally sinned against others before? Ah, no... These guys seem to be terrorists in human terms, and they actually broke into the ranking game... Among them But there are a lot of things that are puzzling..."

Qiye shrugged his shoulders. Among the people who were waiting for him, he was the only one who still had a relaxed expression. Those who didn’t know, thought that these demons were all called by him…

"Hateful fake blood relatives! Gremory! You will die here!"

One of the demons who surrounded Qiye and others provoked Rias. Although the other demons didn't say anything, it could be seen from the expressions on their faces that for these guys who supported the old demon king faction, the current demon king and them The people involved are annoying.

"Boom...!"
