Riser Phenex? DXD SI. Multicross?

[Batman – DC Comics New 52 - 87%]

Couldn't maximize this Template because Batman knows many martial arts. He also has a lot of knowledge in administration. Cough, cough, delegation. Batman is also known as the world's greatest detective, as well as a liar. Cough, cough, I mean actor. He is very capable of acting and deceiving everyone.

Finally, he was ready and grateful for everything; Tsunade had prepared him for the journey. But she wouldn't participate or go. Only my parents, and apparently, I, for some reason, neither baby Ravel nor my other siblings apparently want to go.

There probably must be a story behind this. I'm not sure if my older brother is part of the faction of the great king or not. I just hope this time it's good. So I was ready to leave with Dad at this moment.

Moving through the intricate hall of the Phenex Palace. My father and mother gaze at me. And soon, my mother moves to fix something on me.

"All right. Riser. You're ready. I hope you maintain the proper decorum of the Phenex family. I want you to introduce yourself to young devils and try to make some friends your age. And remember, be careful not to bow. Okay?" Razer Phenex, vulgarly known as my father, an old devil over 1000 years old, who fought in the period of the great war. He's asking me to stay proud. This even seems like some trauma, especially with my mother holding his hand.

"Yes, father."

Riser just nodded and absorbed everything his father just said.

"Before we go. We would give you this when you turned 7. But now, we've been invited to attend this underworld meeting. Give me your hand." Said my mother. Soon, I comply and stretch out my hand, which gains a magical mark. Riser absorbs the part. "Invited to Attend." And just him appearing clearly means they were "ordered."

With this crest, I can finally use the family's magic circle. Although I could do it using natural Archmage. Now I can show that I can do all the nonsense I can do. Without worrying. Obviously, I won't show any of this to them.

"Thank you, mother." Giving the best of my radiant smiles, giving a slight blur on her cheeks.

"That's my little and lovely Riser-Chan!"

"Gasp!" sounds of Riser being deprived of his air source, between the breasts of Rumix Phenex, Lady Phenex. ["Does my mother only do this to me by any chance? I might really end up dying like this."] thought Riser, almost losing consciousness. After all, she was at the peak of the Ultimate class, so she was very strong for Riser at this moment.

Uff! * Uff! * Uff! *

"All right. Stay within the magic circle, or we will be late." Spoke the father, while he looked slightly with a smile at his son. A magic circle of the Phenex family.

Swish! Whoosh! Spark!

A strong glow from the magic circle, and then they were at the entrance of the Gremory mansion. In the room in question, there was a woman waiting. The maid bowed. And then she spoke:

"Lord Phenex, Lady Phenex, Young Master Phenex. Follow me." said the maid. Turning and quickly moving to the next room, almost as if it were a choreographed movement or already done this very often.

Moving to a door intricately coated with gold, similar to a golden hall. There was an announcer for entry into the hall. On the other side of the door, nothing could be heard. The maid and the family entrance announcer were waiting until:

The announcer put two fingers on his neck. On the finger was a small magic circle, and then he whispered.

"RECEIVE THE MOST NOBLE FAMILY OF MARQUESS PHENEX."

As if my parents had fire lit under their butts, they both assumed stiff postures and adopted a "formal" stance. I quickly assume a noble attitude. Just before the doors open.

Upon opening, I see many demons of all ages and genders; I see separate groups, a group of old demons, and one of the most prominent was the Ancestor of the Bael family. Riser imagined he would never leave his castle; he was probably wrong.

Another group with "Young demons," the current Satans, talking in their own circle. And finally, another smaller group than the other two. If we were to compare it to the world of Harry Potter, they would be the gray faction.

After seeing memories from a third-person perspective, he gained the abilities of his Template; through his acquired memory, he felt his Lucifer side, just like Batman, asking him to plan and do something. Fortunately, he didn't gain his personality. But watching all the memories and feeling them, even from an external perspective, would change a person. (A/N: As you came, I put Aang, precisely to balance his spiritual side. As mentioned before, he won't be a saint or good. He has his desires and will do anything to fulfill those dreams.)

At one point, after a short walk, we were in front of 3. 2 redheads and one with shorter brown hair and violet eyes.

"Welcome, Lord Phenex, Lady Phenex, and young Riser Phenex." Said Zeoticus Gremory, with a "kind" smile, just like his wife cast "maternal" glances.

"Lord Gremory, Lady Gremory. And Heiress Gremory." said my father with a smile, almost as if he were speaking to a "friend."

Before the elders could continue talking, Zeoticus Gremory abruptly interrupted the conversation and asked his daughter.

"Rias-chan, could you take Riser-Kun to where the children are? So that everyone can interact." Said Zeoticus, who now had an extremely perceptive look. Assessing Riser. Riser just looked and gave a smile. With this smile, Lady and Lord Gremory, they felt a shiver running down their backs. Just like that lovely little child for a moment, assumed a reddish skin color almost as if her skin had melted in the flames, pointed horns and bat wings appearing.

When they blinked to see if their eyes were deceiving them, the child returned to being adorable. What Riser didn't know is that his ability was always active when his instinct felt that he was being seen as inferior. Being Lucifer, his subconscious pride exploded and activated [First Devil Supremacy].

Unaware of everything that happened, Rias with red cheeks, breaking the decorum completely. She simply grabbed Riser's arm, then pulled him to a group of demonic children.

[Sona Sitri]; [Seekvaira Agares]; [Sairaorg Bael]; [Zephyrdor Glasya-Labolas]; [Latia Astaroth]; [Diodora Astaroth]; [Gandoma Balam]; [Beluga Furcas]; [Kuisha Abaddon] as well as || [Misteeta Sabnock]; [Coriana Andrealphus]; as well as many other members of noble houses, as well as extra and "Extinct" houses. Riser knew that if he played the right things here, he might even gain noble members.
