  [High School DxD World, Rias Mansion]

  "We're finally back!"

  "This trip was quite fruitful!"

  "Yes, everyone caught amazing Familiars!"

  "Roy-sama is really incredible!"

  ...

  The girls chattered excitedly as they returo the mansion.

  They released their Pokémon, filling the mansion with even more energy and activity.

  After a while, they went to rest. After all, they had been camping outdoors for the past few days, and nothihe fort of home.

  Roy and Rias were the only ones left in the spacious living room.

  "Rias, you must have many questions," Roy said softly, sipping the tea Akeno had prepared.

  Their trip to the Pokémon world had revealed many unbelievable things.

  But Roy khe girls wouldn't pry if he didn't offer an expnation. That was one of the things he appreciated about them.

  "Yes, I do have many questions," Rias admitted, setting doweacup and sitting beside Roy.

  She ed her arms around his neck, her bright eyes gazing into his.

  "If you want to tell me, I'll listen."

  Seeing her uanding and supportive demeanor, Roy couldn't resist any longer. He leaned in and kissed her.

  "Mm!" Rias was momentarily surprised but quickly respoo his kiss.

  Suddenly, a burst of fmes erupted in the room.

  A fiery magic circle appeared, embzoned with a fme-like crest.

  Rias seemed to sense who was arriving. She gently pushed Roy away.

  Roy also knew who it was: Riser Phenex.

  But he didn't care. He was focused on Rias.

  The magic circle fred, bathing the room in a crimson light.

  Fmes surged from the circle, and a wave of heat washed over them.

  A figure emerged from the magic circle.

  "Yo, Rias, I've e to get you!" the figure annouhen froze, his eyes widening at the sight of Roy and Rias locked in an embrace.

  His fastantly darkened, and his aura fred with rage.

  Roy finally released Rias, having savored her kiss.

  Rias, her face flushed, caught her breath and turo the newer.

  "Riser Phehis is the Gremory territory," she warned.

  The newer, dressed in a red suit with his jacket casually unbuttoned, was indeed Riser Phenex.

  "Rias, You're a High-Css Devil. How you associate with this trash?" he scoffed, seemingly unfazed by what he had just witnessed.

  "It's none of your business who I associate with! And Roy is not trash!" Rias retorted coldly.

  "Rias, don't fet, I'm your fiancé. I've e to take you back to the Underworld with me," Riser decred, approag her with a smug grin. He reached out to caress her cheek, pletely ign Roy.

  "Callirash? I 't let that slide," Roy said, his voice low and dangerous.

  The room, previously filled with the heat from Riser's fmes, suddenly turned icy cold.

  Roy vanished from his spot and reappeared before Riser, pung him squarely in the face.

  Bam!

  Riser, caught off guard, was sent flying, crashing through several walls before being buried uhe rubble.

  Roy hadn't held back.

  "How dare you y a hand on my woman!" Roy snarled, returning to Rias and pulling her close.

  His possessiveness stunned Rias.

  She looked at Roy with adoration, her eyes filled with warmth.

  "What's going on?"

  "What happened?"

  "Roy-onii-, are you okay?"

  ...

  The otiohe irls to the room.

  "It's nothing. Just an unwele guest," Roy said dismissively.

  Boom!

  The rubble where Riser had nded exploded outwards.

  Riser emerged, engulfed in fmes.

  "You lowly Devil..." he roared, his face torted with rage. "I'll ie yht here!"

  As the third son of the Phenex family, he had never been so humiliated.

  With a wave of his hand, a crimson magic circle appeared, and over a dozeiful girls of various appearances materialized behind him.

  These were Riser's servants.

  Riser, with his harem of beautiful Devils, was the envy of many male Devils in the Underworld.

  "Riser Phenex, I won't let you do as you please!" Rias decred, stepping in front of Roy.

  "Hmph! If you want to hurt Roy, you'll have to gh us first!" Saya retorted, taking out a Poké Ball.

  "Koi, e out!"

  "Roar!"

  A beam of light shot out from the Poké Ball, and the massive Gyarados appeared.

  Its intimidating aura terrified Riser's Low-Css Devil servants.

  Even Yubelluna, Riser's Queen and an High-Css Devil, looked apprehensive.

  Only Riser remained unfazed by Gyarados.

  "Hmph! It's just a beast," he scoffed.

  Indeed, although Gyarados owerful intermediate High-Css with Ultimate-Css Potential, it couldn't harm the immortal Riser.

  Just as the tension reached its peak, a silver magic circle appeared betweewo groups.

  A woman with beautiful silver hair and dressed in a maid outfit emerged. It was Grayfia, Roy's elder sister.

  Grayfia's arrival brought with it an overwhelming aura that pressed down on Riser and his peerage.

  Riser's Low-Css Devil servants, already terrified by Gyarados, colpsed to the ground.

  Even Riser and Yubelluna were intimidated by her power and couldn't help but lower their heads.

  Roy silently praised his sister. She was truly a protective older sibling.

  Without even asking for an expnation, she had asserted her dominance, making Roy feel a bit sorry for Riser.

  He had already been punched by Roy and now had to ehe oppressive aura of a Maou-css Devil. Riser felt utterly humiliated.

  "Riser Phenex," Grayfia said calmly, "the Phenex and Gremory families have decided that Rias e will be determined by a Rating Game between you and Roy."

  "Therefore, until then, please refrain from any unnecessary as."

  "The Silver-Haired Annihition Queen! Damn it!" Riser cursed under his breath, reizing Grayfia.

  He didn't act rashly anymore.

  After all, this was the woman who had challenged Serafall Leviathan, for the title of the stro female Devil.

  "You challenge me to a Rating Game? Hmph! Just you wait. I'll crush you!" Riser threatened before telep away with his peerage.

  Although cocky, Riser was a formidable fighter, ranked among the top ten newers in Rating Games.

  He had only lost once, and that was iional, to maintain good retions with his oppo.

  Roy, oher hand, was known as a failure in the Underworld and had never participated in a Rating Game.

  Whether he even had a peerage was unknown.

  That's why Riser had uimated him.

  After Riser left, Grayfia turo Roy. "e with me."

  "Yes, Sister" Roy replied, instrug the girls to rest, then followed his sister.

  Ohey were gohe girls erupted in chatter.

  "Ara ara, so that's the Silver-Haired Annihition Queen!"

  "Roy-kun's sister is so cool!"

  "She's amazing!"

  "I wonder what she wants to talk to Roy about."

  ...

  Meanwhile, Roy followed Grayfia to a private room.

  His sister was elegant aiful, though her maid outfit seemed a bit out of pce.

  He wasn't sure when she had developed a fondness for maid outfits.

  Of course, Roy didn't mind.

  "Roy, you don't have a Queen in your peerage yet, do you?" Grayfia asked.

  "Uh, no" Roy admitted, surprised by her question.

  He hadn't introduced the girls' ranks when he brought them to the Underworld st time.

  "The me be your Queen," Grayfia decred calmly.

  "What?" Roy's eyes widened in disbelief.

  He had sidered asking Grayfia to be his Queen, but it was just a fleeting thought.

  He wouldn't actually ask her..

  He didn't expected her to offer herself.

  "Of course, Sis!" Roy excimed excitedly.

  He took out the Queen pied ha to her.

  He had long envied Riser Phenex.

  Not only did Riser have a peerage full of beautiful girls, but he had even made his own sister his servant, adding a "little sister" attribute to his team.

  It was a feat that many Devils envied.

  But Roy was no different now. He was about to make his own sister his Queen. The thought thrilled him.

  Grayfia was surprised by Roy's immediate acceptance.

  She found his excitement both amusing and endearing.

  She took the Queen pied merged it with her body.

  A powerful aura erupted, enveloping the entire mansion.

  The girls and their Pokémon were stunned into stillness.

  And this was just Grayfia's uional release of power.

  Then, another powerful aura emerged, rivaling Grayfia's.

  This was Roy's aura.

  Having made Grayfia his Queen, he received a tremendous power boost.

  His strength surged from the mid-level of High-Css > Ultimate-Css > Maou-Css!!

  ...

  After a long moment, they both retracted their auras.

  Grayfia was the first to recover. She immediately noticed the ge in her power.

  Her strength had increased signifitly, almost reag the peak of a Maou-css Devil.

  If she could break through, she would bee a Super Devil.

  Super Devils were at least a level above Maou-Css Devils.

  An ordinary Queen piece wouldn't have boosted her power this much.

  Grayfia looked at her brother curiously, but she couldn't see through his strength anymore.

  Her curiosity about her little brrew.

  "What's going on?" she finally asked.

  "Sister, the Evil Pieces I gave you are mutated pieces I obtained by ce. Every time I gain a servant, my strength increases. Now, I also have the power of a Maou-Css Devil," Roy expined with a smile.

  He attributed the system-granted Evil Pieces to ce, making it seem less unusual.

  He wasn't ready to reveal the system's existe.

  Even so, Grayfia was astonished.

  She had never heard of such powerful and unique Evil Pieces.

  And she was touched by Roy's trust in her.

  "Sister, although you're now my Queen, I won't let you participate iing Game against Riser Phenex," Roy decred.

  "After all, it would be unfair to him if you fought."

  Roy knew why Grayfia had offered to bee his Queen.

  She was worried he would lose against Riser.

  Now that his strength surpassed Riser's, there was no need frayfia to participate.

  Even with his previous High-Css Devil strength, Roy was fident in his victory.

  "Very well," Grayfia agreed.

  Now that Roy was a Maou-css Devil, she had no reason to worry.

  No matter how powerful Riser's immortality was, he was still just an High-Css Devil. He couldn't defeat a Maou.

  Roy and Grayfia returo the living room.

  The damaged walls had been repaired, a testament to the venienagic.

  Roy addressed the girls with a smile. "I have an annouo make."

  The girls looked at him expetly.

  "Sister has bey Queen!"

  The girls were stunned.

  They hadn't expected the aloof and serious Grayfia to bee Roy's Queen.

  "That's great! Now we'll definitely wiing Game against Riser," Asia excimed, relieved.

  She had been worried about the uping match.

  "Yes! Grayfia-sama is as strong as a Maou! She easily defeat that Riser chi!" Alice chimed in.

  "No, Sister won't be participating iing Game," Roy corrected them.

  "After all, It would be bullying to have her fight Riser."

  "And even without Sister, I'm fident we win."

  "Yes, we've been training hard for this. We've all beuch stronger," Saeko added with a smile.
