"R-Riser-Kun, this way, please," Rias stammered as she tried to compose herself. Riser, with an innocent smile, followed her to where the young demons were. After a brief analysis, regardless of Riser's control, it happened automatically when he was under direct observation, a peculiar feature of the Archmage Essence.

Rias, the Gremory heir, with a gentle smile and a curious expression, approached Riser.

"Hello, Riser-kun. Welcome to the Gremory mansion. I hope you feel comfortable here," greeted Rias, maintaining an elegant posture.

"Thank you, Rias-chan. I'm looking forward to getting to know all of you," replied Riser, displaying his innocent smile.

The room designated for the children was decorated with vibrant colors and filled with demonic games. Rias led Riser through the area, introducing him to the other young ones, while trying to ignore the strange feeling that still hung in the air.

The young demons looked at Riser with curiosity. Some whispered among themselves, while others tried to strike up a conversation. Riser, with his charismatic nature and the ability to read people's emotions, quickly connected with them.

Rias led Riser to the group of young demons, where other heirs of noble houses were gathered. The atmosphere was a bit formal, but Riser was determined to break the ice.

"Hey, everyone! I'm Riser, from the Phenex family. Looks like we'll be spending a lot of time together, so let's get along, alright?" said Riser, trying to create a relaxed atmosphere.

The other heirs responded politely but still a bit reserved. However, Riser wasn't discouraged and began asking about them, their families, and interests. He used his natural charm, gradually breaking the initial barrier.

Meanwhile, in the background, the leaders of noble families continued their political discussions and strategic alliances. Riser, in turn, seized the opportunity to observe and absorb information about power dynamics and relationships between houses.

"Hey, you're new here, right? What's it like being a Phenex?" asked a blue-haired demon with yellow eyes, approaching Riser.

Riser smiled, using his ability to connect with people. "Oh, being a Phenex is interesting. We're known for our regeneration power and fire abilities. But, of course, there's much more to it. And you, what's your name?"

The blue-haired demon introduced himself as Diodora Astaroth, and soon others joined the conversation. Riser, with his social skills and charisma, quickly became the center of attention in the room. Meanwhile, Rias watched from afar, feeling a mix of perplexity and fascination.

"Sort of." A little girl with black hair and purple eyes, more like violets, murmured. Riser thought: ["What did she mean by 'sort of'? Is she some master giving an analysis? And what the hell did she analyze in me? I'll just look at her with a gentle smile."] thought Riser, quickly putting on a gentle smile for the little girl.

It didn't take long for the little girl to break her facade: "Um... and um. I'm Sona Sitri, heir of the Sitri family." Said the girl, now recomposing herself.

However, a shadow loomed over the gathering. A silent presence observed Riser from afar, not revealing itself. The great King couldn't help but see this boy. ["How was he able to enthrall all these little devils? Interesting indeed. There was already a desire from Zeoticus in the boy. If it's what I think it is, I give my approval. But the decision comes from the friendship between Razer Phenex."] The great King who had plans for all his descendants. Seeing even her being a member of another family, like his. After all, she inherited his Bael lineage. He would continue to watch over them regarding the capabilities of the young master, being attentive to the subtle change in his aura.

"Pleasure to meet you, miss. I'm Riser Phenex. And if I may ask, the names of the ladies beside you," said Riser, somewhat guiding the conversation to learn more about the ladies since, for some reason, the male devils gathered on one side while the females were in another area but together.

"Cough." With a slight cough and her little nose wrinkling. "I'm Seekvaira Agares, Heiress of the Agares Family of the remaining Diabolic Clans of the 72 demonic pillars," said Seekvaira. But Riser noticed the grace and subtlety with which Heiress Agares spoke, showing a certain maturity and intelligence. ["Sona is still very green; she must be around 3 years old at most, maybe even younger than that. But Seekvaira, she's 1 to 2 years older than Rias, which puts her 1 to 2 years younger than me."] Riser analyzed the two while still maintaining external appearances with his gentle smile.

"Pleasure to meet you. Heiress Agares." Meanwhile, Riser just looked at another girl. Blonde with supernatural blue tips.

"I'm Latia Astaroth. Member of the Astaroth Family Branch." The girl murmured, still somewhat embarrassed.

While the atmosphere in the children's room became more relaxed, time passed in the Gremory palace. Adult demons continued their political conversations and plans for the future. Riser, in turn, took the opportunity to get to know his future colleagues.

"So, what does everyone like to do?" Riser spoke softly, and using [Desire Exposure], [The Great Tempter], [Book of Lies] to get the information he desires, after all, he could try others as a devil's whisper.

Quickly, someone responded.

"Chess! Um. I like how it can represent things. Um. Like the right strategist can beat even the strongest," said Sona. And with these words, he realized that she didn't feel strong compared to her sister. After all, she was the Maou, while she was just Sona. Riser showed no sadness upon hearing her words but gave a comforting smile, showing that he was open to listening to everyone.

"Anime! And Japan! I love everything in that country. Especially how the Knight of Nin-sama showed me his country," said Rias, who apparently already had her love for Japan and anime. Riser realized that she was probably deceived by him. After all, she has no way of knowing all the countries in the world and what she likes the most. Riser remembered Souji Okita being the Knight of the current Lucifer. So he probably took her to Japan, probably at Sirzechs Lucifer's own hotel, Kyoto Sirzechs Hotel.

Riser still remained happy, especially with the information he had collected. Of course, he already knew the things she liked. But he also discovered Sona's insecurity, just as Rias was easily manipulated.

"Mecha is the best. Hmph! I'll make the biggest Mecha with the best technologies. And I'll have a big business in the underworld," said Seekvaira, with a proud tone, showing that she wants to make her house big. Riser also noticed that during their interactions, she was the one who maintained a proud posture.

And a little girl whispered softly. "I want to become the heir of my house. So that it doesn't fall into disgrace," said Latia Astaroth. Who spoke quietly so that Diodora Astaroth wouldn't hear.

Before Riser spoke. He looked around and saw Sairaorg Bael, with a little girl the same age as him, almost glued to him. ["He's falling for the oldest trick in the book."] Seeing Kuisha Abaddon, almost sandwiching the little boy who didn't know how to react. Riser thought: ["If I were the heir of a house, I'd probably be in the same situation."] going back to the previous conversation.

["I have some dreams I want to fulfill. First, win the young devils' rating game. As well as participate in the real deal between the Rating Game. Being the Champion there too. And lastly, but something I want to study. And create a system Opposite to Heaven's. Something like a demonic system."] Riser thought that if he created an evil system, in which he absorbed all the negative desires like the seven deadly sins, as well as thinking of the Devil as the heavenly system that gives faith. He would give cursed energy. Obviously, he would have to think about it because if it's too negative. It would be similar to a Yokai absorbing too much natural energy without purifying the energy. Going into a frenzy.
