With the Three Factions' Peace Conference concluded, Roy returned to his peaceful daily life.

One day, at the Occult Research Club...

"Starting today, I'm the new advisor of the Occult Research Club!" Serafall declared, standing up and striking a pose with her hands on her hips.

Roy, Rias, Sona, and the other girls were all present.

Sona sighed, shaking her head at her sister's antics.

"What's going on?" Rias asked, looking at Serafall in confusion.

"I wanted to see more of Sona-chan, so I asked to be your advisor," Serafall explained.

"And to discuss magical girls with Roy!"

"By the way, Roy, is that Madoka Magica manga you mentioned finished?" she asked, bouncing over to Roy, her eyes sparkling with anticipation.

"Uh... yes, it is. But as a Maou, shouldn't you be busy with other matters? How do you have time to be an advisor?" Roy asked, puzzled.

He remembered that Azazel was supposed to be the advisor. Why had Serafall taken his place?

Of course, if it had been Azazel, he would have objected. After all, Kuoh Academy was an all-girls school.

"I am quite busy, so I won't be here often," Serafall admitted, then held out her hand expectantly.

Roy sighed and placed the completed manga in her hand.

Serafall squealed with delight and immediately sat down to read it, ignoring everyone else.

"Roy, are you sure it's okay to let her read that?" Mine whispered, nudging him with her elbow and glancing at Serafall.

She had already read the manga. It was a good story, but unlike typical magical girl stories, Madoka Magica was quite dark and disturbing.

Roy had called it a "healing" anime.

After watching it, she had been furious. Healing? she had thought. More like depressing.

Would Serafall, who feared nothing, be affected by this dark tale? Would she snap and try to destroy the world?

"Haha, it's fine. I'm curious to see her reaction," Roy chuckled, anticipating the chaos that might ensue.

"I just hope Serafall-sama doesn't cause too much trouble," Rias said with a worried sigh.

They all watched as Serafall read the manga.

At first, she was all smiles.

But then, her expression clouded over.

Her smile vanished, and her face became serious.

As she continued reading, tears welled up in her eyes.

Soon, she was sobbing uncontrollably.

Sona had never seen her sister cry like this before and was quite concerned.

Serafall finally calmed down after finishing the manga, though she remained in a daze.

Roy approached her and patted her shoulder.

"Serafall-san, are you alright?"

"It was amazing!" Serafall suddenly shouted, startling Roy.

"Roy-kun, your manga is incredible! It's unlike any magical girl story I've ever seen!" she exclaimed, grabbing his hand excitedly.

"Um... I'm glad you liked it," Roy replied, surprised by her reaction.

He had expected her to be upset or even enraged, not overjoyed.

"Hey, hey, let's adapt it into an anime! And then make a live-action movie!"

"I'll play Madoka, and Sona-chan can play Homura!" Serafall suggested, her eyes sparkling with excitement.

"Uh... well..." Roy glanced at Sona.

Sona was facepalming, clearly exasperated by her sister's antics.

"That's not a bad idea," Roy said, playing along.

"Yay! Thank you, Roy-kun!" Serafall cheered, hugging him tightly.

Sona and Rias stared at them in disbelief.

They couldn't believe that Maou Serafall, was clinging to Roy and acting cute.

No one would believe this if they told them.

...

Time flew by, and a month passed in the blink of an eye.

Summer vacation had arrived at Kuoh Academy.

As per tradition, Roy and Rias had to return to the Underworld with their peerages.

They gathered to discuss their plans.

"Roy, what are we doing this summer vacation?" Rias asked with a smile.

"Hmm..." Roy pondered for a moment. "How about we visit your family first, then we'll go to my sister's place together."

"And finally, we'll have a training camp. What do you think?"

Rias nodded in agreement. "That sounds like a good plan."

The girls were excited.

"Going to the Underworld while we're still alive is a bit nerve-wracking, but I'll face it with the resolve of someone facing death!" Asia joked.

"Are we going to hell?" Sheele asked with a confused tilt of her head.

"Silly Sheele, the Underworld is just where Devils live. It's not hell," Chelsea explained patiently.

"We're going to meet Buchou's sister? I'm so nervous," Aika, Murayama, and Katase said in unison. It was their first time visiting the Underworld.

"Will we see Grayfia-sama when we go to the Underworld?" Alice asked, raising her hand.

"Of course. She's been wanting us to visit," Roy replied with a smile, patting Alice's head.

"Special training, huh?" Koneko mumbled, petting her cat.

She stood up and approached Roy.

"Roy-senpai, please make me stronger. I don't want to be a burden," she said with a determined look.

Roy was momentarily surprised, then smiled. "Koneko, you're not a burden at all. Don't worry, I'll make you stronger during the training camp."

"That's right, Koneko. You're not a burden. You're my precious servant," Rias added, hugging Koneko.

Koneko had been feeling insecure because she hadn't been able to contribute much in recent battles.

But her resolve to become stronger was unwavering.

And it wasn't just Koneko. Roy had other servants in a similar situation.

For example, Yuriko and Alice were still Low-Class.

But that was normal. It had been less than half a year since they became Devils.

Half a year was nothing to a Devil.

Countless Devils remained Low-Class for centuries.

Shizuka was also a Low-Class Devil.

But she didn't seem to mind, seemingly content with her role as a maid.

It didn't matter anyway, as Roy didn't intend for her to fight.

Saya was also a Low-Class Devil, but she had her Gyarados, so she wasn't in a hurry to increase her strength.

The other girls were all Middle-Class Devils or higher, so there was no need to worry about them for now.

But he had to plan this training camp carefully.

<><><>

The next day, they packed their belongings and boarded the train to the Underworld.

Sona joined them on the luxurious train.

"Sona, after visiting your family, would you like to join us for the training camp?" Roy asked.

"You're going to a training camp? Unfortunately, I've already been assigned a trial by my sister. I won't be able to join you," Sona replied with a sigh.

"That's a shame. But it's alright. We can train together another time," Roy said with a smile.

"Yes." Sona nodded.

"We're planning to visit Rias's family first, then mine. Of course, I'll visit your family as well."

Sona was delighted to hear that Roy would visit her family.

"I'll visit your home after my trial as well."

"It's settled then!"

Just then, an announcement came over the train's intercom.

"Attention passengers, we will be arriving at the Sitri territory shortly."

"See you later, Sona!"

"Goodbye, Sona!"

"See you..."

They bid farewell to Sona, who disembarked with her peerage.

The train continued its journey.

The girls chatted amongst themselves.

With some time to kill before reaching the Gremory territory, Roy took out his game console.

Asia sat beside him, cheering him on.

Koneko sat opposite him, challenging him to a match.

"Roy, where are we going for the training camp?" Kurome asked, munching on candy.

"It's a world filled with Spirits," Roy replied, his attention focused on his game with Koneko.

The girls were intrigued.

"Are they like Saeko-nee-san's Scyther?" Kurome asked curiously.

"If that's the case, I have to catch a strong one," Mine declared, puffing out her chest.

Saya had been showing off her Gyarados, which was incredibly powerful. Even Mine found it troublesome to deal with.

Although she pretended to be unimpressed, Mine was secretly envious.

"No, they're different from Familiars, although they're also called Spirits. And they can greatly enhance one's power," Roy explained, finally defeating Koneko.

Koneko's eyes lit up.

"Roy-senpai, one more round!" she challenged, eager for a rematch.

"Alright, one more round."

Roy accepted her challenge.

"What kind of training is it? I'm so excited," Kiyome Abe said, looking out the window with anticipation.

Soon, another announcement came over the intercom.

"Attention passengers, we will be arriving at the Gremory territory shortly."

"Finally," Rias said, stretching. "Everyone, gather your things. We're getting off."

"Wow! It's so big!" Asia exclaimed, looking out the window at the vast Gremory territory.

The land was neatly divided into different sections, resembling a patchwork of fields.

It was a beautiful sight.

"This is the Gremory territory? It's so beautiful!" Irina gushed.

"It is quite impressive. The Lucifuge territory pales in comparison," Roy commented.

He was telling the truth. If the Gremory territory was the size of a city, then the Lucifuge territory was a district.

Of course, he wasn't including the uninhabited areas.

The Underworld was vast, and the Devil population was relatively small.

Rias chuckled, hearing Roy's comment. "I believe with Roy around, our clan will become even more prosperous."

"Yes, yes!" the girls agreed confidently.

"Hehe, of course. But to truly prosper, we'll need your help," Roy said with a wink, looking at the girls suggestively.

'Their help? Does he mean having children?' Rias wondered, blushing.

The other girls also blushed, understanding his implication.

Roy grinned, then led them off the train.

<><><>

They soon arrived at the Gremory family estate, a massive and luxurious castle.

"Is this Buchou's home?"

"It's amazing!"

Xenovia and Irina were awestruck.

The castle doors opened, and several maids emerged.

"Welcome back, Rias-sama, Roy-sama, and everyone," the head maid greeted them with a bow.

"Let's go inside," Rias said to Roy with a smile.

"Okay."

They entered the castle.

Rias led them towards the dining hall.

Servants and maids lined the long corridor, welcoming them.

"Rias-nee-sama, welcome back!" A young boy with red hair ran towards Rias and hugged her.

"I'm back, Milikas! You've grown so much!" Rias chuckled, patting the boy's head.

Roy looked at the child curiously. 'Could this be Sirzechs's son?' he wondered.

But Grayfia was his sister now. Where did this child come from?

"Rias, who's this?"

"He's my nephew," Rias explained.

"Come, say hello to everyone."

"Okay!" Milikas readily agreed and bowed politely. "I'm Milikas Gremory. Pleased to meet you all."

"He's so cute!"

"Hello, Milikas!"

"What an adorable little guy!"

...

They followed Rias and met her mother, Venelana Gremory.

Venelana was like a mature version of Rias with brown hair. She was incredibly beautiful.
