Riser felt a chill down his spine upon hearing about the pajama party at the Sitri household. He knew Levia-tan's reputation and didn't anticipate anything good.

Still, he tried to maintain composure. "Alright, Dad. I'll behave properly," he said, forcing a smile.

Internally, however, a thousand thoughts bubbled in his mind. Riser could already envision Serafall's bright and seductive eyes, her smile full of malicious intentions.

"It can't be that bad, right? She wouldn't break me, right?" he thought, sighing. He knew he would return from that party traumatized, for sure. Maybe even violated, who knows? Violated in a way no one had thought of, perhaps humiliated, forced to wear magical boy clothes.

"Who are we kidding... she'll probably dress me up as a magical girl," thought Riser, with metaphorical tears falling from his face.

And so, Riser spent the next few weeks; every day, he fought his brother in the morning for a period of 4 hours. After all, with his Phenex body, as long as he had demonic energy, he could stay at the peak. In the afternoon, he studied magic, mechanics, computing, engineering, and lastly, mythologies.

With each passing day, Riser improved, but it was also a day closer to his sacrifice. He had no doubt that his world would undoubtedly be shaken. Riser always wondered why Serafall behaved this way, but no one knew or wanted to talk about it. All that is known is that it has to do with the devil's civil war.

This led Riser to speculate that perhaps she had loved someone once in her life, just like Tsunade in Naruto's natural history. And then she was forced to watch them die. In Tsunade's case, she fled. She fled Konoha to avoid facing her failures, and even closed herself off from love.

In Serafall's case, her personality would be a way of facing reality. She subconsciously forced herself this way. Or what he believed most was that it was all an act, and she was a viper just waiting to strike.

He could only truly speculate about her peculiarities. Perhaps in the future, she would tire of the magical girl act, or maybe not. There are stories that Levia-tan was able to convert some of the oldest devils on the council of the 32 devil houses to use a magical girl wand. In other words, never underestimate the chaos that a Levia-tan can cause.

"Riser, everything ready? I'll just take you to the entrance. After we introduce you to Lord and Lady Sitri, I'll leave you with the other kids," said Razer, who seemed happy. With his son approaching the other children, he might be able to secure many marriage contracts. And in his contract with Gremory, there is no clause against a harem; so he really hoped his son could seduce more of these girls. Although he didn't say anything to Riser.

Riser just nodded in acceptance. A magic circle of the Phenex appeared, and with a flash of light, Razer and Riser disappeared.

(Sitri Palace)

The main entrance of the Sitri palace was imposing, reflecting the power and prestige of the family. Tall columns of white marble flanked a majestic wrought-iron gate, with intricate designs representing the clan's history. The family crest, an intricate blue symbol, was prominently stamped at the top of the gate.

On the other side, a wide path of gray stones meandered through meticulously maintained symmetrical gardens. Beds of exotic flowers and bubbling fountains gave an air of refinement to the place. In the background, the palace itself stood imposing, its light stone walls contrasting with the blue sky.

It was a scene that conveyed power, wealth, and tradition. Riser couldn't help but be impressed by the opulence of the Sitri family as he entered those gates. At the same time, a chill ran down his spine at the thought of what awaited him inside, in the hands of the dreaded Levia-tan.

"We're here, son. Now behave yourself, okay? No funny business," said Razer, patting Riser on the back.

The boy swallowed hard and nodded. Inside, his heart was racing. Today was the fateful day, the dreaded pajama party with Serafall.

They were greeted by Sona's parents, who greeted Riser politely. The boy forced a smile and shook the hands that were extended to him.

"Enjoy, Riser," said his father. "I'll be back to pick you up tomorrow."

Riser looked in panic as his father disappeared in a flash, leaving him to his own devices. Swallowing his fear, he followed a butler to the party venue.

There, he found a group of children chatting animatedly, all wearing cute pajamas. Except for Serafall, who wore a tiny pink babydoll full of frills.

Riser froze immediately; he knew he was witnessing the dream of many guys in the underworld. But he wondered, ["Where's Sairaorg?"]

"Ris-Chan!" exclaimed Serafall, drawing attention to the new guest and the last to arrive.

"So-Tan was waiting for you!" she said with bubbly joy and a smile that promised mischief.

All the girls who were chatting turned to see Riser, who had just arrived. He was waving to them. Since decorum wasn't needed, the first to run and give him a "hug" was Rias. A red meteor crashed into the stationary Phenex. Serafall also took the opportunity to approach Riser.

Once close enough, she crushed them in her magical girl packages, leaving Riser breathless. After a few moments, both Rias and Serafall stepped back.

"So-tan wants to see you," whispered Serafall in Riser's ear, with a smile that was anything but "sweet."

Grabbing Riser by the arms, Serafall dragged him to where So-tan, Rias-Chan, Seek-chan, and La-chan were.

"Hello, Sona, Seekvaira, Latia."

Sona was blushing and could hardly start the conversation, Seekvaira was still being formal with a slight smile, Latia was maintaining a noble posture, and for some reason, they were all watching something with a smile on their faces.

"For you who just arrived! Ris-Chan! We're watching a marathon of the wonderful Miracle Levia-Tan show; we're watching all the seasons!" cooed Serafall, embarrassing her little sister. Now Riser knew why Sona was embarrassed, but she wasn't angry; she even had a magical girl wand in one hand.

"Serafall..."

"Sera-tan or Levia-tan," Riser was interrupted.

"Sera-tan. I even thought about taking photos and stuff. To put in an album. After all, it's a memorable moment?" Riser asked, for which Sona sent an expressionless look to Riser.

"Oh Ris-chan! I already have magically installed cameras to take the best photos. You can relax. Ris-chan, Miracle Levia-T

an has thought of everything," said Serafall, giving a "Okay" sign, while sticking her tongue slightly out and winking.

Riser sat in his chair, and magically on the small table appeared a glass with a drink and some cookies.

["Phew! I thought something bad was going to happen to me. This is completely normal, I would say. Normal too much. Only Serafall is dressing a bit provocatively. But she's older and everything. So I think nothing bad will happen."] Riser thought he had won this battle, little did he know he had just started a war.
