As Ethan--no, Aengus--descended from the dark mountain, MANAS projected his system panel before him. From now on, he didn't need to give commands; MANAS would execute them with just his thoughts.

Aengus took a brief glance at the screen but said nothing. His focus was singular, his mission clear: to grow powerful, no matter the cost.

"Master Zero, I will now enter standby mode to conserve Mana. You just need to gather the materials I asked for. Once you have them, I'll help you complete the process. Only then can we solve our Mana shortage. Until then, use your demonic skills to grow stronger."

Aengus still didn't know why she insisted on calling him 'Zero.' When he asked, she simply replied that 'Zero' was the name registered in her system, though even she didn't know how or why. The name itself was a mystery.

Aengus just nodded without a word and continued along the hollow, elongated path. His duty as a Demon Slave of the Incubus Demon Duke's mansion awaited. Succubus Bella had granted him shelter in exchange for his service, and for now, he was bound to her command, like a Servant.

The change in occupation was more than just a title; Aengus had indeed become Bella's servant, though her treatment of him was unexpectedly kind. There was a strange, unspoken understanding between them, despite the nature of their relationship.

What gnawed at Aengus, however, was the bitter irony of his situation. Through a twist of fate and the powerful synthesis with the demonic core of the Dreadnaught Colossus, Aengus now carried the bloodline of his greatest enemy--Beelzebub.

His level, which had previously been 21, had dropped to 20 due to the damage inflicted by the Dreadnaught Colossus, and the fusion.

After the synthesis, Aengus's body had gained the unique ability to hold two opposing energies--Mana and Nether energy--each contained within a newly added created space, where his demonic Core and Mana Reserve pool floated --opposite to each other .

These energy storages existed in a precarious state of harmony, as if compelled to coexist. However, if they ever fully embraced each other, it could be catastrophic, potentially destroying his already weakened body entirely.

The idea of synthesizing these energies storages into something greater had crossed MANAS's mind, but she knew his current body couldn't withstand the process.

So, she devised another plan to create an energy converter within him, allowing Nether energy to be transformed into Mana and vice versa. This innovation will solve their immediate Mana problem, providing a temporary yet vital solution to keep Aengus alive and growing stronger..

Comimg to his newly obtained demonic abilities, he had recived 4 from the Dreadnaught Colossus, and the heart of darkness had been formed inside within him because of the despair and hatred he felt due to the recent incidents.

1. Gluttony of Darkness (Basic):A dark, consuming force that allows Aengus to absorb energy, life force, or even objects to increase his own physical stats and recover power in time of need. It's both offensive / defensive ability--the most powerful one.

2. Darkness Pulse (Basic): A pulse of dark energy that emanates from Aengus, disorienting and weakening those around him.

3. Darkness Veil (Basic): A shroud of darkness that cloaks Aengus, making him nearly invisible and allowing him to move unnoticed.

4. Darkness Haki (Basic): An intimidation aura that exudes from Aengus, allowing him to command lower-ranked demons and beasts, even against their will. This ability bends weaker minds to his will, making them submit to his authority.

5. Heart of Darkness (Peak):The most profound change within Aengus. This ability represents the embodiment of his despair, hatred, and resolve.

- The Heart of Darkness grants him heightened control over dark energy, a near-immunity to lower-tier darkness attacks.

- An increased capacity for regeneration and endurance.

It is the core of his darkness power, constantly feeding on the emotions that brought it into existence. This power has a passive ability to keep his mind calm, no matter the situation. However, as a side effect, he can no longer feel any emotions within him.

And lastly he had lost his precious sword, the last equipment, that had the memory of his old self--Bright and cheerful self.

.....

Soon, Aengus arrived at the imposing mansion of the Demon Duke, an Incubus Lord who wielded considerable control over the region. This grand estate, reflection of his power, was the residence of the Incubus Duke--a figure renowned for embodying lust and charm. As it happened, he was also Bella's father.

The Incubus Duke's influence extended over millions of demons within his vast dukedom. His domain included several marquis states, each governed under his strict authority.

His political power was far-reaching, while his military prowess was equally formidable, with an army numbering nearly 1,000,000 demon soldiers.

His force contains different kind of demonic species and creatures, their ranks ranging from Lesser Demons to Elder Demons, each bringing their unique strengths to his need.

The Incubus Duke's individual might was unmatched, marking him as a Demon General Rank powerhouse. His abilities were legendary, with a reputation for both his strategic acumen and sheer combat prowess, making him a central figure in the demon world's power structure..

There are far more powerful demons out there. The demon Lords and Primordial Seven Deadly Demons, each representing their their sin.

A Demon General could just be said placed at the third stage in the hierarchy.
