The moment he finished the sentence, I immediately started firing at Azrael hundreds of Dark Light Weapons as I opened the Gate of Babylon to the maximum. With the new addition of a new part of my TThe rue Name, Isaiah, as I was fighting in the Underworld, I significantly boosted my Demonic Energy regeneration.

Though, Azrael had the same advantage, as we were fighting in an environment that was rich in Death Energy, so he could effortlessly recover what he used.

'Architect, scan him. Use detection of Laws.'

I said in my head. After I reached Super-Devil Class, then I could barely sense the presence of Laws, due to my low Energy Reserves, as I am just a newly advanced Super Devil, I cannot sense them more, not to mention comprehend, but when I am close to somebody I had some tricks to know if someone had started comprehending Laws.

[It shall be done.]

Said Architect; as soon enough, I had analysis on Azrael before my eyes, as he was busy dodging the Dark Light weaponry that was constantly being shot at him.

[Race: Fiend / Angel Hybrid

Class: Archangel

Laws: Death, Darkness, Light

Abyssal Energy: 15,000

Holy Power: 15,000

Strength: 5,890

Agility: 5,156

Vitality: 6,054]

'Damm... he is strong. Even his physical body is already in the same rank as his Class. And he combined Abyssal Energy and Holy Power inside his body... fascinating.'

I thought in my head.

Abyssal Energy was native to Fiends living in the Abyss. It was even more negative and more aggressive than Demonic Energy, not just more harmful but even wilder and more destructive.

Demonic Energy was just a sub-type of Abyssal Energy, that was calmer, more versatile, and easier to control.

Each one had its advantages and disadvantages.

What shocked me was how he managed to find equilibrium, but not only that, he had already started comprehending Laws. One needs to know that Angels didn't need to comprehend Laws to reach the next level, not even Fiends required; they just needed to evolve.

But yet, Azrael already started comprehending the three Laws of Death, Darkness, and Light. If he reached the Angel Emperor stage, he would be invincible among those of the same level. One needs to know, aside from Arcanists, almost none of Power Systems required comprehension of Laws, so it was easier to reach, for example, Warlock Monarch than Arch-Arcanist Level.

'He isn't going to evolve before comprehending those Laws... he is searching for his own path. This is interesting.'

"Have you finished checking me?"

Asked Azrael as I grinned; of course, he managed to evade every attack flawlessly I threw at him.

"Yes, and I must admit, this is getting interesting!"

I shouted with a grin as I materialized Rosenkreutz in my hand and conjured several Ultra-Order Tier Spells, such as [Dimensional Slash] and [Black Hole], and sent everything at Azrael.

A case of literary theft: this tale is not rightfully on Amazon; if you see it, report the violation.

Even though I have right now used around half of my energy reserves, within several minutes, I will be at my peak, as my regeneration speed is tremendous right now thanks to my True Name Isaiah.

This time, Azrael looked at the incoming attacks warily as he took out some unnamed sword that I didn't recognize and coated it entirely with Holy Power and slashed through incoming spells with ease, which made me smile.

"It would be too easy that way, right?"

When he saw me smile, it was too late, as several [Black Hole] spells that were near him imploded out of nothing and started sucking into themselves every once of Abyssal Energy and Holy Power he had.

In an instant, I sensed that his energy reserves were cut to half.

[Black Hole] was a spell that I devised; it had two functions. It could draw objects to itself, and everything that would enter the [Black Hole] would be eroded to death by its power. Second, I could switch it to energy-devouring mode, and it could absorb enormous amounts of energy in a short time.

This was the first time I have used the [Black Hole], so it was like a trial test. And the results were even better than what I had expected.

I knew that Azrael was many times stronger than me, so my primary strategy was not to allow him to come close, as that would be my death warrant.

I successfully implemented my strategy until Azrael started ignoring incoming attacks and started getting closer and closer, with a sword in his hands, cutting down my attacks with ease while suffering one injury after another.

"Ts."

I frowned as I cast a teleportation spell and teleported tens of kilometers away while barraging Azrael with even more magical attacks.

When I appeared several kilometers away, I sensed that somebody was standing behind me and aimed a sword at my throat.

"While you are strong for your age, and even among your Class, you are top; you still lack experience."

Azrael was standing there with a smirk as he said that.

"You copied my teleportation spell and calculated the way where I would appear, right?"

I asked as I deduced how he makes it here at the same time.

"Yes, you need to mask the intent of your moves during battle better, or it would cost you more than lost spar."

He said as he stored the sword away.

"So, what now?"

I ask as I have fulfilled his condition for a fight and wasn't that away from defeating him, even though it was mainly due to elements of surprise over my magic.

"I pledge my allegiance and that of my Legion to follow the Emperor of Baator. From now on, through Eternity, till Death."

He said as he dropped on one knee, and Soul-Geass Scroll appeared between us.

"And I accept your pledge and that of your Legion; I promise to lead you to glory and victory, Azrael, Archangel of Death and Leader of Death Guard Legion."

I said as I gripped the Soul-Geass Scroll as the contract between us was now completed.
