They all gathered at a discreet underground train station beneath Kuoh Academy. After descending several levels, they reached the platform where a sleek, elegant train waited.
Its design blended modern technology with demonic artistry dark crimson and black metal with glowing runes along its sides.
The group boarded without much fanfare. Silas took a seat near the window, Rias settling on one side of him and Akeno on the other. The rest of the peerage filled the surrounding seats, chatting quietly with a mix of excitement and nerves.
The train began to move. It accelerated rapidly along the tracks, yet none of them felt any jolt or turbulence. The ride was perfectly smooth, almost unnaturally so.
Silas looked out the window, watching the underground scenery blur past glowing crystal veins, vast caverns, and strange demonic flora flashing by in seconds.
' I was about to ask myself how nobody has ever seen this,' he thought, 'then I remembered how dumb all the NPCs are in this world.'
They soon entered a long, pitch-black tunnel. The lights inside the train dimmed slightly as everything outside went completely dark.
A few moments later, they emerged on the other side. The view had changed entirely. They had successfully entered the Underworld.
The sky above was a deep, eternal crimson, with no sun but a strange, ambient red glow illuminating everything. Massive floating islands drifted in the distance, and enormous demonic structures ancient castles, towering spires, and sprawling cities dotted the landscape. The air felt thicker, heavier with raw demonic energy.
Rias smiled softly, squeezing Silas's hand. "Welcome to the Underworld," she whispered.
The train continued its smooth journey toward the Gremory territory, the vast and powerful domain of Rias's family. Silas leaned back in his seat, taking in the new world around him with a small, intrigued smile.
'This should be interesting. Can't wait to see her mother again 'he thought.
They arrived at the grand Gremory Residence, the massive mansion sprawling out like a palace under the crimson sky of the Underworld. A long line of servants stood in perfect formation along the entrance path, all dressed in crisp black-and-red uniforms, bowing deeply in unison as the group approached.
"Welcome home, Lady Rias," they chorused smoothly.
"Woah, so many maids…" Issei muttered, eyes wide and practically sparkling as he stared at the beautiful women in uniform. A thin trail of blood started dripping from his nose. "This is a dream come true…"
The maids, of course, ignored the perverted dragon entirely, their expressions remaining perfectly professional.
Silas casually slung an arm around Issei's shoulder as they walked forward, smirking.
"Maybe if you asked nice enough, they'll let you crack one," he said.
Issei's nosebleed intensified instantly. "Y-Yeah… I should ask one of them to visit me tonight…"
Silas chuckled. "Good. Maybe this will finally cleanse you from your perverted nature."
"Doubt it," Koneko muttered as she paused for a second, having overheard them.
Silas turned to the small Nekoshou girl and placed a hand on the back of her head, gently pushing her forward as they kept walking.
"Did you pass?" he asked.
"Of course I did," Koneko replied, puffing her chest out a little.
"Really? Guess I'll have to reward you then," he said, smirking.
Suddenly, everyone up ahead stopped. Silas lifted his gaze and saw Grayfia standing there elegantly, followed by a young boy with deep red hair — Millicas Gremory.
"Hello, Auntie Rias!" the boy called out cheerfully, running over and hugging her tightly.
Rias's face lit up as she hugged him back, lifting him slightly.
"Oh, you've gotten so big now! What is Grayfia feeding you?"
"Veggies," Millicas replied proudly.
Silas shook his head slightly, thinking back. 'My mom used to force me to eat veggies. I didn't really like them… until she threatened to tell Goku and I began feasting.'
Rias then introduced the boy to the group. Issei and Asia looked shocked, both of them staring with wide eyes at the young heir. Silas and Xenovia, on the other hand, watched silently, neither particularly impressed by the whole scene.
Grayfia stepped forward with her usual graceful poise, though her cheeks still carried the faintest trace of pink.
"We have supper prepared for your arrival," she announced smoothly. "Please follow me."
Before anyone could move, a soft, elegant voice drifted down from above.
"It's nice to see you all again."
Everyone looked up. There, leaning casually against the curved staircase railing, stood Venelana Gremory. Rias's mother descended the stairs with effortless elegance, her long crimson hair swaying like silk, her mature figure accentuated by a form-fitting dark red dress that clung to her curves in all the right places. Her violet eyes sparkled with amusement as she took in the group.
She stopped right in front of Rias, cupping her daughter's face with both hands and smiling warmly.
"You look spoiled," she said, her tone playful yet knowing. "I'm assuming my son-in-law has been 'taking care of your needs.'"
Rias turned bright red instantly.
"Mom! Not in front of my peerage!" she complained, though she made no effort to deny it.
Venelana's gaze shifted to Akeno next, noticing the same satisfied glow on the black-haired beauty. Her smirk deepened. "You as well. I'm impressed~"
Akeno bowed her head slightly with a small, respectful smile. "Greetings, Madame."
"Please, call me Mom," Venelana said warmly. "Since you'll be my daughter's sister-wife."
The casual declaration made Akeno's cheeks flush just a little, but she accepted it with graceful poise.
Venelana then turned her attention to Silas. He was standing slightly apart from the group, glancing out one of the tall windows, seemingly lost in thought.
'He really does have the aura of a powerful man,' Venelana thought, her eyes tracing his relaxed but confident stance. 'No wonder my daughter and the others are so attached. Devils do have a strong attraction to power, after all.'
She smiled softly and clapped her hands once.
"Let me not make you wait any longer. Please, follow us to the dining hall. We've prepared a wonderful supper for everyone."
Grayfia and Venelana led the way, the two elegant women walking side by side with natural authority.
The group followed them through the grand hallways, the sound of their footsteps echoing softly against the polished floors.
Rias stayed close to Silas, slipping her hand into his as they walked. Akeno stayed on his other side, while the rest of the peerage trailed behind, chatting quietly among themselves.
The dining hall was breathtaking a long, ornate table set with fine silverware, crystal glasses, and an array of delicious-smelling dishes already laid out. Servants stood ready to attend to every need.
As everyone took their seats, Venelana sat at the head of the table with Grayfia beside her, while Rias pulled Silas down to sit between her and Akeno.
The meal began with light conversation, but the undercurrent of tension and excitement was impossible to ignore.
After dinner, Venelana personally gave them a short but informative tour of the massive Gremory Residence.
She led the way with graceful confidence, pointing out key areas, the grand library filled with ancient tomes, the training grounds used by past generations, the beautiful indoor garden with glowing Underworld flowers, and several ornate sitting rooms meant for receiving important guests.
Silas listened quietly, hands in his pockets, taking in the details without much comment. The others asked occasional questions, but his attention was mostly on the layout itself.
When the tour ended, servants showed everyone to their assigned rooms. Silas was given the largest suite a spacious master bedroom with a massive four-poster bed that could easily fit five or six people comfortably, complete with its own sitting area and private balcony.
He stared at the enormous bed for a second.
'Did I gain weight?' he thought, genuinely confused for a moment.
Since it was already quite late, everyone eventually retired to their rooms. Rias and Akeno, of course, followed Silas into his.
The moment the door closed, the three of them wasted no time.
Clothes came off in a heated rush. Silas took them both on the huge bed, railing them thoroughly in the soundproof room.
Their moans and cries stayed contained as he fucked them senseless first Rias on her back, legs over his shoulders, then Akeno from behind while she ate Rias out.
He switched between them multiple times, filling them both with load after load until they were trembling, covered in sweat and cum, and completely passed out in a satisfied heap on the bed.
Silas stood there for a moment, breathing steady, looking at the two beautiful, exhausted girls tangled in the sheets with a small smirk. He cleaned himself up quickly, threw on a pair of loose pants, and left the room.
'I should check out the manor by myself,' he thought. 'It's nice to memorize the layout.'
He wandered the quiet halls for a while, noting corridors, staircases, and key rooms without making a sound.
The mansion was even larger than it seemed during the tour, endless hallways, hidden passages, and luxurious spaces that spoke of centuries of Gremory power.
Eventually, he stepped out onto a wide balcony overlooking the vast Gremory lands. The view was mesmerizing rolling crimson hills, glowing forests, and distant spires under the eternal red-tinted sky of the Underworld.
The temperature around him suddenly dropped.
Silas didn't turn around.
"Grayfia," he said calmly. "What brings you here?"
The night air grew colder as Grayfia's presence filled the balcony behind him.
