  Having decided to rescue Mio Naruse, Roy immediately set his pn in motion.

  But first, he informed Rias and the others, even though he would be ba a fsh. He didn't want them to worry.

  Rias and Sona readily agreed and didn't ask to e with him.

  They khat if Roy wahem to e, he would have said so.

  There was no need for them to apany him to the world of—Shinmai Maou ament.

  And so, Roy vanished from the room.

  ....

  Uhe bright night sky, Roy appeared above a bustling city.

  "So this is the world of Shinmai Maou ament..." he mused, a smirk pying on his lips.

  He sed the city with his senses, instantly pinpointing the current time and location.

  He found Mio Naruse and Maria Naruse fleeing through a dark alley.

  Mio was one of the main heroines of this world.

  And Maria was a succubus who had been threatened int as Mio's guardian.

  They were being chased by a group of Stray Demons.

  Mio had ied immense power from her father—the previous Demon Lord, making her a target for both Stray Demons and Demons from the Demon Realm.

  But she couldn't trol her ied power yet.

  Although she has great potential—her own power was being suppressed by her father's flig energy.

  She couldn't eve a few Stray Demons.

  And Maria—tasked with watg over Mio, was essentially useless in battle.

  So, they had no choice but to run.

  Roy, the se—stroked his thoughtfully.

  He teleported to a location ahead of Mio and Maria.

  There was an old, abandoned house.

  Roy waved his hand, and the dipidated house instantly transformed into a beautiful two-story mansion with a small garden filled with flowers and trees.

  It wasn't a grand castle, but it was cozy and fortable.

  Roy nodded in satisfa.

  He ehe house. It was fully furnished, with everything they might need.

  He then cast a subtle suggestion spell on Mio and Maria.

  When they reached this pce, they would ehe house and hide.

  And he had pced a barrier around the house, preventing the Stray Demons from entering.

  Having made all the necessary arras, Roy bre of tea—turned oV, and waited for the two girls to arrive.

  ....

  "Mio-sama, be careful!" Maria excimed.

  Mio and Maria were still running. These Stray Demons were different from the ones in the world of High School DxD.

  They were more like ghosts, appearing and disappearing without warning.

  A Stray Demon suddenly materialized behind Mio, and Maria cried out in arm.

  "Haa!" Mio also noticed the attacker.

  She leaped forward, narrowly dodging the attack.

  Then, she spun around and faced the Stray Demon, summoning a magic circle that unleashed a torrent of crimson fmes.

  Boom!

  The Stray Demon was instantly ied.

  Mio sighed in relief, exhausted from the stant running and fighting. She colpsed to the ground.

  "Mio-sama, we have to keep moving," Maria urged, helping her up.

  Mio khey couldn't stay here, so she forced herself to stand.

  "Let's go."

  They tinued running, supported by Maria.

  After a while, they realized that there were no more Stray Demons pursuing them.

  "It seems they've given up for now. Let's rest for a bit," Mio said, her face grimy and exhausted.

  "Yes, Mio-sama. That house over there looks nice. Let's go there," Maria suggested, pointing towards the beautiful mansion.

  "But... isn't that inappropriate? There might be someone living there," Mio hesitated.

  "Don't worry, Mio-sama. We'll just stay for one night and leave tomorrow. The owner won't even knoere here," Maria reassured her.

  She had dohis many times before. They would leave before the owner woke up, and she would cast a spell to erase their memories.

  "Alright." Mio agreed.

  They ehe courtyard and admired the beautiful garden. Mio wondered what kind of person lived here.

  Ding-dong!

  The doorbell rang.

  Roy, knowing they had arrived, opehe door.

  "May I help you?" he asked with a smile, looking at the two girls.

  On the left was Mio Naruse, who looked almost identical to Rias, especially with her long red hair.

  And on the right was Maria Naruse, a petite silver-haired succubus.

  Mio and Maria were stunned by Roy's appearance.

  They had seen many handsome men, and this wasn't a world where looks mattered.

  But they had never met anyone as naturally handsome and charming as Roy.

  Their first impression of him was excellent.

  "Um..." Mio blushed and looked down, flustered.

  Maria, oher hand, grinned mischievously. "From today onwards, we're your little sisters!" she decred.

  She then cast a Charm spell on Roy.

  An ordinary person would instantly accept them as his sisters uhe influence of this spell.

  Of course, Roy wasn't affected by such a low-level spell, but he decided to py along.

  "Wele home, my dear little sisters," he said with a warm smile, inviting them inside.

  "Maria, is this really okay? I don't want to lie to him anymore," Mio said, her sce b her.

  She didn't want to manipute this kind man.

  "Mio-sama, we 't be piow. Besides, wouldn't it be o have this handsome man as our older brother?" Maria asked with a pyful grin.

  Mio was flicted. She couldn't deny that the idea was tempting.

  It would be wonderful to have a g older brother...

  ....

  "My dear little sisters, you must be hungry. I'll prepare dinner for you," Roy said, leading them into the house.

  "Wow! It's so here!" Maria excimed, impressed by the tidy living room.

  "It seems our new brother really cares about us," Mio ented with a smile.

  After running for so long, she was indeed quite hungry.

  "Yes, he's so kind..." Maria agreed.

  Soon, a delicious aroma wafted from the kit.

  Mio and Maria couldn't help but salivate. They wondered what he was cooking.

  They tiptoed towards the kit and peeked inside.

  "Onii-, what are you making? It smells so good!" Maria asked, sniffing the air.

  Roy turned around with a smile. "It's ramen. It'll be ready soon."

  "I 't wait!" Mio excimed, her eyes sparkling with anticipation.

  The ramen was soon ready.

  Rht the bowls to the dining table.

  Maria was about to dig in, but Roy stopped her.

  "You have to wash your hands before eating."

  "Ugh..." Maria pouted, clearly unhappy.

  "Yes, Onii-," Mio said, taking Maria to the bathroom to wash their hands.

  "This is so troublesome," Maria grumbled ihroom.

  "Washing hands before meals is important. You're just zy," Mio scolded pyfully.

  "Fine. But this brother is different from the other humans we've charmed before. He's actually taking care of us," Maria ented, recalling their past experiences with the Charm spell.

  Those who were charmed usually became a bit dull and unresponsive, not this attentive.

  "Maybe he really does have a little sister," Mio suggested.

  She didn't find anything strange about Roy's behavior. She simply felt safe and fortable around him.

  They finished washing their hands auro the dining table.

  "Here you go," Roy said, pg the bowls and utensils before them.

  They eagerly took a bite.

  "Mmm... This is delicious!" Maria excimed, her eyes widening in surprise.

  This was the best ramen she had ever tasted.

  Mio also nodded in agreement. The fvor was incredible.

  "Eat as much as you want. There's plenty more," Roy said with a chuckle.

  He was amused by their reas. His cooking skills were top-notch, of course.

  "Another bowl!" Maria finished her bowl in record time and held it out for more.

  Roy smiled and refilled her bowl.

  "Onii-, please!" Mio also requested a refill, her face slightly red.

  Roy filled her bowl as well.

  Both of them—had quite the appetite. They ate several bowls before finally feeling full.

  They leaned ba their chairs, satisfied.

  But when they saw Roy clearing the table, Mio immediately stood up.

  "Onii-, let us do that," she offered, taking the dishes from him.

  They felt bad for havien so much delicious food without doing anything iurn.

  "Alright, then I'll leave it to you," Roy said with a smile.

  The two girls started ing up.

  ....

  I...

  "Mio-sama, why are we doing this? It's s," Maria pined as she washed the dishes.

  "Onii- made such delicious food for us. It's the least we do," Mio replied.

  "But we're leaving tomorrow, aren't we?" Maria asked, realizing that Mio wasn't pnning on leaving.

  Mio fell silent. She had started to see Roy as her real brother.

  After their adoptive parents were killed by Zolgear, they had been on the run stantly.

  They had finally found a warm and weling home, and a kind older brother. She didn't want to leave.

  Maria, seeing her expression, uood her thoughts.

  "If you don't want to leave, Mio-sama, the's stay," she said.

  "But..." Mio was tempted, but she was also hesitant.

  There were Stray Demons stantly trying to attack her. She didn't want t dao her new brother.

  "Don't worry, Mio-sama. There's no danger now. If there is, we always leave," Maria reassured her.

  "Alright." Mio finally agreed.

  They decided to stay.

  Roy, in the living room, overheard their versation and smirked. Everything was going acc to pn.

  ...

  "Here's your room, Mio," Roy said, showio a guest room.

  The room was fully furnished and decorated with femiouches.

  Mio instantly fell in love with it.

  "Thank you, Onii-!"

  "You're wele. Get some rest," Roy said, patting her head gently.

  Mio blushed, enjoying his touch.

  "Onii-, where's my room?" Maria asked.

  "It's door. I'll show you."

  "No need. I'll stay in Mio-sama's room," Maria decided.

  It was better to stay with Mio and protect her in case of a Stray Demon attack.

  "Maria, you should go to your own room," Mio suggested.

  "But Mio-sama..."

  "It's fine. I'll be okay."

  "Alright." Maria relutly agreed.

  "Good night," Roy said with a smile, thehe room.
