Understanding Riser and Sirzechs!!!

(First person, POV Riser Phenex)

The loud bang and screeching voice of Levia-tan interrupted our intimate moment, making me shudder. I raised an eyebrow in her direction, my lips twisting into a grumpy grimace.

SCREECH! The doors of the main hall were ripped from their hinges as the hyperactive figure of Levia-tan burst in, her long black hair flying behind her like a silk cape.

"Sera...?" Rias murmured, blinking a few times as if struggling to process the noisy interruption.

"Kyaaaaa!! My Rias-chan and my beautiful Riser-tan!" The little devil shot towards us like a missile, her eyes wide with manic joy.

THUMP! Before we could react, Levia-tan launched into a crushing hug, her tiny arms wrapping around us like frenetic tentacles. (A/N: have you noticed how thin her arms are, though. She could probably level a building with a punch.)

"Ack! Sera... can't... breathe..." I gasped as she squeezed us like a constrictor snake, practically crushing the air from my lungs.

"Oooh, but I missed you sooo much!" Levia-tan whined, her angelic face twisted into an exaggerated pout. "You two barely visit me lately! Levia-tan gets so lonely without her favorite toys!"

CRUNCH! A worrying sound of bones cracking filled the air as she intensified her grip.

"Toys...?" Rias coughed, her face starting to turn red from the effort. "We're not...ugh... toys, Sera..."

A disappointed grunt escaped from the little devil's lips as she finally relaxed her suffocating embrace. Shaking her head frenetically, her hair flew around us like a black silk curtain.

"Awwww, but it's so fun to play with you!" Levia-tan hummed, her large bright eyes blinking innocently. "Rias-chan is always so badass, and Riser-tan is sooooo baaaaad!"

A warm blush crept up my neck as she emphasized the last word, stretching the syllables with a teasing tone. I cleared my throat, trying to regain some of my composure after the suffocating hug.

"Sera, how many times do we have to tell you not to call us that?" Rias pursed her delicate lips, although her eyes shone with resigned indulgence.

"Awwwww, but you love when Levia-tan calls you that!" The little devil purred, leaning forward to flutter her eyelashes in an exaggerated gesture of false innocence. "Don't you, Riser-tan? You love it when I emphasize the 'baaaaad' in you."

GULP! I choked, struggling to control the blush now burning my cheeks.

"I-I don't know what you're talking about," I managed to grunt, clearing my throat again in a desperate attempt to seem indifferent.

A mischievous smile curved Levia-tan's lips as she cast me a complicit glance from beneath those thick lashes. A mischievous spark danced in her amber eyes as she turned to Rias.

"Nee, nee, Rias-chan! Do you think your Riser-tan is also 'baaaaad' in bed?"

PFFFTTT! Rias spit out a small cloud of air, blushing furiously at Sera's bold insinuation. A choked sound escaped my throat as I arched my back, swallowing hard.

"S-Sera!" I gasped, shocked by her audacity. "You can't just..."

But my attempt to scold her was cut off when the little devil burst into crystalline laughter, almost doubling over with the intensity of her mirth. A reluctant smile curved my lips as Rias shot me an exasperated look over her shoulder, rolling her eyes.

"You... You're terrible," Rias finally managed to say, shaking her head in feigned mockery.

BOING! Levia-tan did a little somersault backward, landing gracefully on her tiny feet like an experienced gymnast.

"I know you love it, Rias-chan!" She hummed, winking naughtily. "That's why Levia-tan is always here to spice things up!"

A deep chuckle escaped my throat as I looked at the little mischievous creature. As exasperating as Levia-tan could be at times, her presence injected a vibe of chaotic joy into the mansion. A breath of fresh air that blew through the austere, decorated rooms, leaving a trail of frenetic laughter in its wake.

"I'll admit, Sera, you certainly keep things... interesting," I teased, raising an eyebrow as she cast me a sly, feigned look.

A loud crack of thunder suddenly boomed, making all of us shudder. A blinding brightness flooded the tall windows for a brief moment before dissipating.

"Oooh, look! A storm is coming!" Levia-tan squealed, her eyes sparkling with excitement. "Let's go outside and dance in the rain, Riser-tan and Rias-chan! It'll be so much fun!"

With a dramatic spin, she darted toward the torn-off doors, her hair flying behind her like a black silk cape. A bemused sigh escaped my lips as I stepped forward to follow her.

"We'd better go. You know how she gets when denied her fun."

Rias nodded in agreement, her soft smile lighting up her face as she linked her arm with mine. A glittering lightning bolt sliced the sky in a shimmering fractal, accompanied by a deep rumble of thunder that echoed through the mansion walls.

In that moment, there was nowhere else I'd rather be...

...

(Some hours later.)

After entertaining Serafall enough, Rias had fallen asleep, receiving a lap pillow. And with that, we could finally get to my question. It was something very simple. Why was she here? After all, it should have been her younger sister visiting me. Given the fact that I am engaged to her. But it was she who visited, meaning she is here because of her job as Maou.

"Riser-tan." Whispered the voice, Serafall. "Where did you go and why did you disappear? We all looked for you. For weeks. You know saying that testing a new magic module wouldn't work." Stated Serafall, shedding her magical girl facade.

"I'll be honest. And I don't intend to hide it from you. The Maous I mean. Even the other girls anyway. I traveled to another dimension. It was something I used in a test, Which didn't go so well, I even face-planted as soon as I got there. The world I went to. Was an alternative version of our world. Basically the events of this world with some differences. The biggest proof will be when I introduce the other girls I brought. Some of them are historical beings. Who will probably cause problems for the faction. If they know about them." I spoke to Serafall, about Medusa, Medea, as well as the current state of Sakura. Because I didn't talk about Rin and Illya. Well, the Mesopotamian gods, kind of no longer exist. And Illya, a minor goddess. That isn't so relevant.

deep breath

Serafall stared at me with her eyes wide open, her jaw slightly dropped. For a long moment, silence reigned between us, only the occasional distant rumble of thunder breaking the quiet.

"Another dimension?", she finally managed to say, her voice lower than usual. "Riser, that's... well, I don't even know where to start."

A contrite smile curved my lips as I nodded, my expression serious. I knew it would be hard for her to accept the truth, but Serafall deserved to know. After all, we had been allies for a long time, our lives intertwined in ways deeper than most could imagine.

"I know it sounds crazy," I admitted softly. "But it's the pure truth. I was sucked into a parallel universe, a place where the events we know unfolded in slightly different ways."

CRACKLE! A sudden lightning illuminated Serafall's perplexed features, outlining her angelic features with a supernatural glow. Her eyes sparkled with a mix of confusion and skepticism as she let out a long trembling breath.

"But... how? How is it possible to travel between dimensions like that?" She shook her head lightly, her long black locks flying around her face. "And what kind of differences are you talking about, exactly?"

I leaned forward, my elbows resting on my knees as I carefully chose my next words. Explaining something so extraordinary would require delicate care, each detail distilled with surgical precision.

"Well, for starters, the historical events we know here occurred slightly differently in the other world. Some of the figures and mythological entities we've studied were real there, living and breathing just like you and I."

Serafall's eyes widened even more when the implications of my words hit her. A flash of shock crossed her perfect face before she calmed her features again.

"You mean... beings like those from ancient Mesopotamia and Sumerian? Or the deities from the Norse pantheon?" She stuttered, her voice faltering a bit.

I nodded slowly, letting the idea sink in. "Exactly. I met famous figures like Medusa and Medea. They were as real as us."

RUMBLE! A low roll of thunder roared outside, almost overshadowing my next words as I continued.

"And those weren't the only ones... there were others. Individuals of great power that we could never imagine existing in our world."

I paused, allowing Serafall to process the full meaning of what I had just shared. Her eyes remained fixed on me, a spark ignited in those amber depths. I could see the gears furiously turning in her mind as she considered the vast ramifications of this revelation.

Finally, after what seemed an eternity, she let out a long, trembling sigh, as if bracing herself to dive into unknown and perilous waters.

"So... what else can I expect, Riser?", she asked softly, her voice nearly muffled by the rumble of the approaching storm. "What else did you bring back from that... parallel universe? Besides, of course, goddesses and demigoddesses from another pantheon?"

My lips curled into a slow smile as I tilted my head in a solemn gesture. Yes, she was ready to face the truths I was about to reveal. Truths that would shake the very foundations of the world she knew.

"Much more than you can imagine, my dear Levia-tan," I murmured, my eyes shining with an inner fire. "Much, much more."

KRAAAACCCKKKKK! A thunderous clap shook the walls as a dazzling lightning bolt tore through the night sky, bathing us in a blinding flash of white light. It was as if the cosmos itself was reacting to the magnitude of what I was about to share.

Taking a deep breath, I prepared to start telling Serafall about the wonders and dangers I had encountered beyond. Each word would be carefully chosen, each sentence meticulously crafted to capture the magnitude of this experience beyond normal comprehension.

After all, how could a mere demon describe the mysteries of a world where myths and legends came to life? But I had to try. An alternative version of our world. And with supernatural beings like ours.

"**

(After telling Serafall...#$%#.)

"So what happened in my absence? Didn't the old council get too nervous about the delay in activating my system? Besides, I managed to gain access to a dimension where I can place the system. It will be temporal." I said to Serafall, who was processing everything I had told her before. And the future ramifications that my actions could cause.

"Well, as everyone knows, we devils are a chaotic race. It's not unusual for a young master to challenge someone and 'disappear' suddenly. So the devil council thought you had possibly. Gone to a better place. Then, they wanted to organize Rating games for you. Even in your absence. After all, if you didn't return it would be the right time to acquire some things. And these things would be your brides, of course." Serafall said with a 'sweet' smile on her face. I couldn't help but sweat a little at the sight, remembering that Sona would also be 'offered'.

"And Sirzechs just accepted this? As did Ajuka? Wouldn't they fight for Rias and Latia?" I asked Serafall, seriously interested in what they did.

"Indeed, normally, yes. But in this case, it would directly interfere with the Maou, in the houses of the Pillars. So what we could do was delay as much as possible. The only thing we couldn't do, was the case that whether you appear or not. You will have to fight against any future suitors for the hand of your wives. And currently almost all houses have submitted a request to fight against you. Even the extra demonic pillar houses." Serafall said, twirling a lock of her hair, while swinging her legs. Giving news that would normally shake the relations of the pillars.

I also realized that my 'Father', the current head of the house, did nothing to prevent it. Or at least nothing effective. I also remember that I am a Super devil. But in the house, there are only 2 Satan classes. Being Tsunade and my mother. With my departure, this left them weakened. Even exposing my little sister Ravel.

"Did they try something funny for my sister?" I asked Leviathan, who now had a solemn attitude with my speech. She knew that this would not please me.

"Yes. Among all the houses. One stood out in its foolishness. One of them challenged the hand not just for one of the brides. But, all at the same time, as well as your sister. And it didn't stop there. But also, made an offer to your nobility members. Already, taking your death for certain." Hearing Serafall, for the first time I felt an unusual rage from anything I had ever felt. It was as if the whole world was made of fire. The air was fire, the ground had turned to fire. My hand was fire. My power for the first time in this life. Was out of control.

Serafall's words echoed in my ears like a death sentence. I felt the fury burn through my veins, incandescent and overwhelming, like molten lava running under my skin. How dare they? How dare they threaten what was mine by divine right?

FWOOOSH! A wave of demonic power burst from my body in a scalding explosion. The air around me rippled and distorted, the ground trembling under the raw discharge of my unleashed anger. Through a red mist, I saw Serafall take a few steps back, her eyes wide with shock at the intensity of my reaction. In my rage mist, I did not notice that she had removed Rias from me. How disturbed am I?

"Riser! You need to calm down!" she squealed, her voice almost muffled by the deafening roar that echoed in my ears.

But I barely heard her, consumed by the overwhelming fury that scourged within me. Tearing images filled my mind - my precious Rias, forced to submit to the whims of an unworthy suitor. My beloved Ravel, disrespected and dishonored by those who should protect her.

CRACK! Something broke inside me, the floodgates of my containment bursting in a flood of unrestrained energy. Shards of demonic power crackled around me like furious lightning, marking the ground with smoking grooves.

"Who?" I demanded in a guttural growl, my words barely distinguishable through the waves of force that enveloped me. "Who dared to profane what is mine?"

A frightened glint ran across Serafall's face as she stepped back a few more steps, frantically gesturing with her hands in an effort to calm me down.

"Riser, please, you need to control yourself! Your power is out of control!" KRAKOOM! A thunderclap boomed outside as a dazzling lightning bolt tore through the night sky, briefly illuminating the pleading expression on her angelic face. However, her plea fell on deaf ears - the beast inside me was loose, roaring for blood and vengeance.

A deep growl vibrated from my depths as I turned towards the wide-open door. I felt a burning and primitive need to hunt, to pursue those who had threatened what was most precious to me. My fists clenched so hard that my nails sank into the flesh, releasing a slow flow of blood that evaporated in the air with a hiss.

"I will find them," I growled, my voice low and dangerous. "Each one of them. And when I am done, not a stone will stand on stone of their accursed Houses." Then I headed towards the demonic forest. Where I could unload this anger, without anyone succumbing to my power.

In an instant, a trail of light darted toward the forest. Serafall, although capable of moving at FTL, was momentarily stuck. After all, Riser is capable of making an Adora Burst, to use his Severed Universe ability. By cooling space, he is able to slow down time. So to speak. Besides the fact that Riser is capable of reaching FTL, and now with his new Big Will, which has granted him even greater abilities.

Booooooooom!

** (Pov. Rumix Phenex.) I see my son depart in the distance, as he moves. It was as if space itself bent in his presence. In the instant of his anger, he had turned into the very primordial flame. His aura was violent enough, to even push away a Maou, experienced from the civil war.

"See. He cares about his Sister." I say to the Orchestrator of this meeting. Turning to see the Crimson Lucifer. With a sheepish smile, followed by his wife-maid.

"Lucifer-sama, to what do I owe your presence?" I went straight to the point, to know why he was coming here. Assuming a serious stance.

"We will be in conflict, very soon with the old Satan faction. We have received information that they are interested in your son." Maou Lucifer said, and then I immediately understand. why he gave my son a test. Probably to see if he is reliable to protect his sister.

"I understand. So am I to assume that the test was more to see if Riser was reliable? And see how he would react?" I make one of my doubts. After all, there must still be something missing.

"No." Stated simply the Crimson Devil. "Of course, you could say about that. But also wanted to know about his power. Now I could feel. Even if maybe not in its entirety. But, I know he is strong to hold his new position." Asserted the Crimson Devil. As if it were no surprise. Riser a Maou, but I remember my son didn't want that. Because that would mean more paperwork for him to do. "I know he doesn't want the position because of the paperwork. And thus, also has the fact of him being young. But, he shows a high degree of maturity. And I am fully sure that in case of necessity, he would not abandon the devils, as well as friends, family. The main reason is that I cannot guarantee that all Maou came out of this encounter. So..." Sirzechs made a grave pause, for me to respond accordingly.

"A backup plan. In case one falls, you will have a substitute for the Maous." I affirm to him. And am answered with an almost sign.

"Not for the Maous. But for the True." He affirmed again more vehemently. My eyes widen in shock. I never expected that he would want to relinquish his position. Or even he believes he could die. Besides the fact that, from the beginning of the conversation, he has been directing where it should go. Indeed, a Lucifer.

"But, you becoming the Lucifer. What about you?" I asked him, once again. Starting to understand this complex character we call Lucifer.

"You know. This reminds me of how it all started. I never really wanted to be the Maou, or become the head of the faction. I was born at a time, in which a devil like me, from the house of pillars being born with more power, was a crime. Just like your case, right? You and I. We would probably be summarily executed. All in the prerogative of maintaining the status Co. so we hid. And we continued our lives. All I wanted was to continue in my own world. And make a choir. Actively participated in playing instruments for the orphans, as well as I taught them. We sang and performed for the public. I knew that the society of the Devil was cruel. Where the stronger dominated the weaker. Upon returning one day to the Orphanage I saw the children whom I had helped raise, as well as teach. I saw them. All dead. Dead in all the most horrible ways I could describe. The Satan group, not only had attacked the Orphanage. But destroyed the entire village. Tens of thousands dead. It was the turning point. It was the moment something I had held back was released. And then we are here." Asserted Sirzechs. And then I understood. Sirzechs was not telling a fictitious story, but rather what could happen to Riser. While he pursues his dream in projects. The world moves towards war and chaos. If something bad happened to his family or friends. What would he do?

Both Sirzechs and Riser are the same coin, in a way. Both at a moment were equal. I didn't need to say anything else. He even expected that if something bad happened to Riser, he would force himself into a position of power, just to prevent something like that from happening again. I imagined Riser was more like Ajuka. Now I see that I was mistaken.
