Debut 1

Rias and everyone were startled as they saw Kiba as their most reliable comrade to be defeated so early! 

Then, soon, many mirrors seemed to surround them, but—

"HOW DARE YOU?!" 

Rias released her power of destruction, destroying all of the mirrors that appeared, but the voice that she had been waiting for could be heard. 

"Did you defeat that person, Buchou?" While Issei was sad and frustrated as Kiba was easily defeated, he was also happy when he thought Rias had defeated the person who defeated Kiba. 

"No..." 

As she stood in the middle of the ruined room, Rias realized how difficult this match would be. 

However, this sudden defeat of Rias' Knight surprised everyone who watched the Rating Game between Rias and Sona. 

"What's happening?" 

"Why did Rias' Knight suddenly retire?" 

"Mirror? If I am not wrong, something came out from the mirror before." 

At this moment, no one could maintain their calm, and subconsciously, they all looked in the direction of Riser and Serafall. 

Still, Serafall was proud. "Hmph~! So-chan's peerage members are all strong~!" 

"Serafall, can you clarify our doubt?" Even Ajuka was surprised. 

"Er..." Serafall hesitated as she stared at Riser. 

"It's okay. You don't need to worry, as everyone will realize it sooner or later." 

As this match was publicized and watched by everyone, there was no doubt that many people would understand the trick behind the defeat of Kiba. In other words, it was only time for them to know what the secret behind this attack was, but more importantly, even if they knew, could they do something?

"It's a mirror, right?" Odin suddenly said. 

"Yes." Riser nodded. "My wife's Queen's Sacred Gear is Mirror Alice. With that Sacred Gear, she can manipulate the mirror and even enter the world of mirror." 

"Then..." 

"Yes, she came out from the mirror and attacked Rias' Knight swiftly before returning to the world of mirrors." 

"...." 

Everyone fell into silence. 

Mirror Alice might not be a Longinus type of Sacred Gear, which was the strongest type, yet the convenience that was brought by this Sacred Gear was so ridiculous! 

The world of mirrors! 

Then, as long as there was a mirror, wasn't Sona's Queen invincible?

Still, many also thought that this world of mirrors was a good place for them to run away in case they encountered a danger.

In other words, this place could work like a shelter. 

Riser also thought about promoting this ability to everyone and used it as a business, giving them access to the world of mirrors, so in case they encountered a danger, they could enter this world, escaping from that danger. 

With that idea, Riser felt that Tsubaki Shinra could become the wealthiest landlord in the world. 

"Hmph~! It's all because of Riser-chan~! If Riser-chan didn't teach Tsubaki-chan, then her Sacred Gear wouldn't be so strong." 

"Don't say some nonsense, Onee-chan."

"But that's the truth!" 

Hearing Serafall's story, they thought about the school that was opened by Sona. 

If their younger generations could be taught by Riser, then... they didn't mind letting them enter the school opened by Sona. Even if this "Rating Game" school was made for the low-class devils and reincarnated devils, the existence that was at the bottom of the hierarchy didn't matter as long as they could get close to Riser. 

"Can you let me do some research on this world of mirrors, Riser?" Ajuka asked, as he was interested in this type of power. 

"Let's focus on the Rating Game first, as the match hasn't ended yet." 

With those words, everyone focused their attention on the match once again. 

After destroying the whole room, Rias and her group stand in a circle to watch over their surroundings. 

"How did they defeat Kiba?" 

Unlike the audience area, where they knew the secret, Rias and the others were still clueless. 

Still, the loss of Kiba was hurt as Kiba was the one with the calmest mind among Rias' group. Losing him meant that Rias' group lost an element that could cool down their minds, as the only ones left were those hot-headed fools and cowardly ones. 

However—

Akeno took out a paper talisman and threw it into the sky as she murmured some mantras before it turned into several crows. 

"Rias, I will scout the area." 

"Thank you, Akeno." 

Rias took a deep breath and realized that she couldn't lose her cool. "Gasper, help Akeno to scout the area too." 

"Yes, Buchou!" 

Gasper used the power of a vampire and turned himself into swarms of bats. 

With the two powerful scouts, something similar wouldn't happen again, and Sona needed to think twice if she wanted to attack them.

Yet—

"Rias!" 

"Bu-Buchou!" 

At this moment, all of them were dumbfounded as Sona didn't make them wait. Unlike Sona's previous sneak attack, this time, Sona used a frontal battle to attack them, and she used her two most trusted warriors to attack Rias and her group. 

"It seems that Sona really underestimates me." 

Rias frowned as Sona only sent two of her peerage members to attack her group. 

"Don't mess up, Saji."

"I should be the one who said that, you fool!" 

Saji felt like being insulted when Xenovia tried to remind him not to mess up. 

"Saji, focus!" 

"..." 

Saji took a deep breath, trying to control his emotions as he knew talking to this fool was a waste of time. Nevertheless, he wondered how this fool could get the heart of Riser, which still puzzled him. 

Still, Saji knew that he needed to face this battle. 

"Only you two?" Rias asked. 

"Yes." Xenovia nodded. 

"Gremory-senpai, you should give up." 

If it was before, Saji might not be so unrestrained, but to be honest, he really couldn't think of the possibility of them losing. 

"We won't admit defeat!" 

Without a surprise, the one who answered was Issei. 

"I am not talking to you, pervert." Saji looked at Issei with disdain. He knew that Issei was an idiot, so it was a waste of time to talk to him, but it didn't mean he was looking down on Issei as he knew this idiot was the holder of Boosted Gear. 

Even if Issei was an idiot, as long as he held the Boosted Gear, his existence couldn't be ignored. 

"Per-Pervert..." Issei couldn't deny it as he was really a pervert. 

"As he said before, we won't admit defeat. No, we will defeat you." 

"Is that so?" Xenovia felt that talking more was a waste of time, so she just raised her Durandal, and a pillar of golden light pierced through the sky. 

When this pillar appeared, everyone was stunned as it happened so suddenly. 

"You idiot!" Saji screamed before he ran away. 

However, Xenovia didn't care and shouted, "DURANDAL!" 

As those words fell, the enormous pillar of golden light also fell, swinging in the direction of Rias and her group! 

"...." 

Rias and everyone fell in silence as they watched the attack, which was about to fall in their direction, but someone quickly reacted. 

"Forbidden Balor View!" 

Gasper's eyes shone in a strange light before Xenovia's movement suddenly stopped. It was his Sacred Gear, Forbidden Balor View, which could be considered one of the most powerful as it gave him the ability to control time. 

Using this ability, Gasper stopped the time around Xenovia and Durandal, so this attack would stop, but as expected.—

"Buchou, run!" 

Gasper roared for the last time, giving time for Rias and the others to escape, but—

*BOOOOOOOOOOOOOOOMMMMMM!*

[The Bishop of Rias Gremory has retired.]

"GASPEERRRR!!!" 

"How dare you?!" 

Rias was furious, but Sona never gave mercy. 

"This isn't a time for you to lose your emotion, Rias." 

At that moment, at the bottom of Rias and everyone, a mirror appeared, and all of them disappeared. 

Except—

"Hyoudou, let's have a one-on-one battle." 

Saji was going to complete the mission given by Riser.
