''Oh... this Sirzechs really knows how to make things more interesting...'' Altair rambled to himself as he looked at the landscape around him.

Was it a forest? No... it was the occult club.

Just as Altair imagined, they are in the space dimension created specifically for the Rating Game. And how did he know this? Just by looking up at the sky, where there was a greenish aurora borealis...

A beautiful setting, that Altair could not deny.

"Master, can you hear me? Artoria's voice sounded in his head, waking him from his thoughts.

''I hear you, Artoria.'' He said mentally, but still looking at the surrounding landscape.

''Good. What should we do now?'' Artoria inquired, causing Altair to raise an eyebrow.

''What is your situation?''

"At the moment, we are surrounded.

This answer from Artoria caused him to widen his eyes slightly.

''How many?'' He asked as he looked even more intensely around him for enemies.

''More or less ten people...'' Artoria answered in an indifferent tone, as if these ten people were just ants, and well... She wasn't wrong.

''I see... you mentioned 'we are', is Jeanne with you?'' He asked as he jumped on a branch of a tree to conceal his presence, and also to get out of sight of the audience.

''Yes...'' She answered simply.

Master... your permission...'' Artoria asked.

After that speech of hers, sounds of explosions could be heard, they were probably being attacked by Riser's minions.

''No need to hold back, it's impossible for anyone to die here, so you can attack with everything.'' Altair said smiling.

And he knew one thing, even if he wasn't seeing the situation of his two servants, he had one certainty... The two are laughing because he could finally fight with all his strength.

''Understood.'' As she said that, the mental connection was cut off by her, probably because she wanted to focus on the battle.

''Well... now it's my turn to have fun...'' Altair commented to himself as he jumped from tree to tree in a specified direction.

...

...

Meanwhile, in an arena located in the center of the forest. Two people were staring at each other in a hostile manner.

Riser was dressed in something resembling a battle suit, but which covered only his arms and shoulders.

"Buchou, just wait. I will end this quickly.'' Declared Issei summoning his gauntlet on his left arm.

Boost!

''Does he really think he can defeat Onii-sama?'' Ravel inquired with a smug smile on his face.

She was in the stands watching the battle, because even though she was part of Riser's peerage, she couldn't do much, so she preferred to just watch.

''Hmph, in that case, I will close that mouth of yours in just five seconds, in a way that it will never open again.'' Having said that, Riser made wings of fire appear on his back to take off at the next moment.

''Buchou! I require permission for a promotion!'' Issei asked seriously.

''Issei... what are you trying to do?'' She mentally inquired.

''Promotion, Queen!'' As she shouted those words, Issei felt her magic power being increased exponentially.

''That's useless.'' Riser commented as he launched a fireball in Issei's direction.

''Buchou, I want you to listen to me!'' Issei shouted as she jumped to the side to dodge Riser's attack.

Rias who heard this began to pay attention to what Issei was going to say.

''I'm not a swordsman like Kiba. And I am not a genius in magic like Akeno-san. I don't have superhuman strength like Koneko-chan. And even less do I have wonderful healing powers like Asia.''

Those quoted by Issei turned a little red as they realized that the devils began to pay attention to you.

''Still... I want to become your most powerful pawn, no... I will be the most powerful devil in the underworld.''

The devils who heard that statement widened their eyes.

Because this goal of Issei's was not something simple to accomplish, quite the contrary, it was extremely difficult not to say impossible.

''And for you... I would even destroy God, even if it cost my life in exchange for it!''

Rias was very flushed at this statement from Issei.

''Master of all your power! Over-Boost!'' As he said those words, the center jewel of his Boosted Gear began to glow in an intense greenish color.

Welsh Dragon Over-Booster!

Just like that, a red-colored draconic armor with green jewels all over its structure with a pair of rocket thrusters on the back of it appeared, covering its entire body.

''That...'' Rias muttered perplexed at the image in front of her.

''That's the power of the Sekiryuutei! Balance Breaker: Boosted Gear Scale-mail!'' Sounded Issei's voice mixed with ddraig's voice at the end of his statement.

Most of the devils in the place widened their eyes in shock as they recognized the armor Issei was wearing.

''The legendary Balance Breaker?!'' Rias exclaimed in surprise.

''And to think he already reached that level...'' Grayfia commented to herself.

''True... that's a really annoying power.'' Sirzechs commented smiling.

''But, you don't look annoyed, Sirzechs-sama.'' Said Grayfia glaring at Maou who felt a bit ungracious at her intense gaze.

''You think so?'' He inquired with a dull laugh.

...

...

''I want to make a deal with you.'' Issei asked seriously while looking at his left arm.

''Interesting. You know the consequences don't you?'' An imposing voice sounded through Issei's room.

''That doesn't matter. If I want to win something, I'll have to give something else of equivalent value, won't I?'' Issei inquired, but it sounded more like an affirmation as it elicited a light laugh from that being on his arm.

''Indeed, you are quite interesting. But, are you ready for this?'' Ddraig's voice sounded, but this time you could hear a malicious tone in his voice.

I won't change my decision... so will you do it or not? Issei was already starting to get annoyed with all this procrastination, all he wanted was the power and not to keep talking.

"I already told you. The more you sacrifice for me, the more power I will give you in return. But remember this: ten minutes.'' Ddraig said seriously.

''I know. Unfortunately, my body won't be able to take more than that.'' Issei said as he clenched his fists somewhat hard. But still he was somewhat happy, at least they were not mere seconds.

It seems that the insane training he had done with his Kouhai was the right choice.

''Do you think you can handle it?'' Ddraig inquired with a sarcastic tone in his voice. He knew that if Issei reached an extreme point in his battle with Riser, he was likely to unleash that forbidden power of Boosted Gear.

''That's enough!'' He replied simply.

...

...

''Here I come, Riser!'' Exclaimed Issei as he activated the thrusters on his armor and advanced at high speed towards Riser.

He was fast...

But not fast enough that Riser couldn't keep up.

*Four Pawn of Riser Phenex have been eliminated!

''What? Riser exclaimed in surprise.

And that was a mistake on his part.

Because of this moment of his distraction, Issei managed to punch him in the face with a powerful punch, sending him flying towards the forest.

...

...

''Well... this is the fourth.'' Altair commented as he stored a golden sword back into his treasure using his skill.

On the way, Altair had run into Marion and Burrent, Riser's maids, along with Shuriya and Mira.

And since they were unaware of his presence, all it took was a sneak attack by summoning his sword, which contained a certain amount of the sacred element, and using his speed, it was not difficult.

And best of all... It consumed almost none of his mana this attack.

But there was still something poking Altair's head.

And it is that he felt it as he touched the hilt of the sword... The knowledge of how to wield it, the maximum amount of mana that can imbue the blade, its durability...

Everything...

The only thing that was missing in himself now, was experience.

''Hm? What's that?'' She inquired to herself as she noticed something flying towards her.

He couldn't see it due to the darkness of the forest, but it was something humanoid, at least he thinks. But his instincts said he should dodge it.

And so he did, jumping to the side, he managed to get a better view of what passed near him.

Actually, it was two people.

These two people kept going in a straight line until they brutally hit a rock, destroying it in the process.

''You...'' Altair commented a bit surprised to see the two figures getting up from the ground.

''My head, I have to control these impulses better.'' Issei muttered with his voice a little muffled because of the helmet he was wearing.

"You damned worm..." Riser muttered angrily as he slowly stood up.

But as they stood up, they realized that they were not alone.

''What a thing, huh?'' Altair inquired with a sarcastic smile on his face.

''YOU!'' They both shouted in surprise as he pointed at Altair who was leaning against a tree.

''Wow, you look like you've seen a ghost. Screaming is not good for the throat, even if you are devils.'' Altair said smiling cynically.

This caused a vein to pulsate in the foreheads of both of them, but they both took a deep breath to calm themselves down.

''Tell me, Altair...'' Issei said catching the attention of the two present on the scene.

''Did you really sleep with Buchou? Be honest...'' He asked Altair, who only sighed.

''No. She who appeared out of nowhere in my room, but it only took one blow from Avenger to get her out of the picture and then, Grayfia showed up and took her away.'' Altair explained calmly while earning a confused nod from them.

Of course, there were still some doubts in their heads. Like for example, who was this 'Avenger'? But this was no time for that...

''I see. In that case, after I'm done with you, I'll go after this 'Avenger'.''' Riser stated seriously, making Altair laugh, as if mocking that statement.

''What's so funny?'' Riser clearly irritated by Altair's laughter.

''You just said you will fight her, how is that not funny?'' Altair inquired rhetorically with a sneering smile.

''How dare you...'' Riser muttered furious that he was being made a fool of by a mere human.

''He thinks he doesn't stand a chance?!

''And another thing, you said 'when you defeat me', isn't the right one 'if you defeat me'? Altair asked, smiling.

"IT DOESN'T MATTER. I, RISER PHENEX, WILL SHOW YOU THE TRUE MEANING OF HELL FOR BOTH OF YOU! Shouted the completely angry Phenex as a yellowish aura began to surround his body, imposing a great pressure on the air around him.

[The skill King's Domain was activated!]

[Riser Phenex had a 50% increase in his status points]

''Great...'' Altair thought rolling his eyes.

[The skill Red Emperor Dragon's Fury was activated]]

[Sekiryuutei had a 150% increase in his status points]

''What?'' Altair mentally inquired in surprise.

Looking at the young man in armor, he saw that greenish aura surrounding his body.

''Don't tell me, that he has mastered this ability?'' He thought.

[Quest Alert!]

''I thought you would never show up...'' Altair thought sighing with relief.

He didn't want to fight for nothing, that's why he was waiting for a system Quest related to this battle to appear.

[Two formidable enemies appeared in front of him!]

- Requirements: Defeat the Sekiryuutei and the Phenex Heir.

- Rewards: 14,000P, Upgrade Pearl x10, and 10,000 Exp.

- If you lose: You will be in a coma for 2 months and will suffer a 50% reduction of your status, permanently.

''Time to have some fun...'' Altair thought as he gave a big smile to the two opponents in front of him.
