Growth

"Fuck, that shit was painful," Klaus said, struggling to stand up.

"Yeah, but do you feel that the energy that flows through us," Virgil said, releasing his cursed energy

"You're right; this does feel good. I feel like I have limitless energy," Klaus replied

"Uhm, Klaus...Virgil, is that you boys?" a voice asked them.

Looking up, they both saw their parents: their mother, who was filled with concern, and their father, who had a straight look on his face.

"Ah, Mother and Father, I guess you have a lot of questions, but even I don't know why our bodies grew like this," Klaus replied

"Honey, look at their wings; I have never seen such wings before," their mother said

Looking behind them, both boys saw that they had two pairs of wings, but unlike most wings, these ones looked like dragon wings, and the inside flesh glowed like a wild flame.

"...I have seen them before, but only from a picture my father showed me. They are the Demonic Vampiric wings, the wings of Lord Lucifer and his wife," Their father said

"Demonic vampiric, I never heard of that in the show," Virgil said to Klaus.

"That's because they were from the novel; they are the most powerful devil wings one can have," Klaus explained.

"I see; well, it seems like luck is smiling on us," Virgil said with a grin.

"Boys' I don't know how this happened, but you must never show those wings to anyone until you learn magic, or else your lives will forever be in danger," their father said, placing a hand on each of their shoulders.

" We understand, Father We won't show our wings to anyone," Klaus said before Virgil could say anything.

"Thank you for understanding; you boys' relax for the night; we will deal with the questions for that energy you released," Their mother said as both of them left the room

"What the hell, Klaus? We have the power to protect ourselves. Why should we hide it?" Virgil asked Klaus 

"Because we already are an abnormality, using our skill right away without any training would bring unnecessary trouble," Klaus explained, sitting on a chair.

"Fine," Virgil said, taking a seat next to him.

Both sitting down, the boys opened their systems and began to look over their stats.

"That's a lot of skills," Virgil said with a grin on his face.

"Funny you have all those skills yet neither of them can get past my room or barrier," Klaus replied

"Do you really think that I can't get past your barrier with dismantle," Virgil said, holding his hand up.

"I don't think you can; and plus, if I activate the room, you won't be able to do shit," 

"Do you think you could activate room before I use dismantle," Virgil said, standing up.

"I do," Klaus said, opening his inventory and pulling out his weapon, which was Law's sword. The only difference was that it was infused with Ema and increased the radius of the room.

With a grin, Virgil pulled out Hiten, a cursed tool that allows him to use cleave without making contact with the person or object.

As they both held their weapons, the air became thin. If anyone were to walk into the room, they would most likely pass out from the tension. 

...

CLANK!!!

As both weapons made contact, the wall behind Klaus was cut into dust, and the hallway behind Virgil had a long slash that reached the other side of the estate.

Taking a step, Virgil used dismantle, sending three invisible slashes at Klaus. With a grin, Klaus activated his room. With complete command of the area around him, he stopped the invisible cuts. 

"Chambre," Saying those words, Virgil was teleported in front of his attack.

Allowing the cuts to move, they hit Virgil, but to Klaus's surprise, the attacks stopped, and only the walls around him.

"Did you forget about my infinity," Virgil laughed, standing up.

"I didn't. I just wanted to see if your attack could break through it," Klaus said, putting his sword away.

"Ok, okay, and what happened to not using any skills," Virgil teased, looking at the mess around them. 

"...Fuck, you did that on purpose, didn't you," Klaus said 

"I didn't do anything; you were the one who took out your weapon first," Virgil said, holding his hands up.

As the two boys were arguing, their mother and father barged into the room again after hearing the commotion.

"What happened? Are you two alright," their father asked.

"Who did this? Did someone attack you," their mother asked, checking their bodies for any wounds.

"No, Mother, we got a little too carried away testing out the strength; please forgive us," Klaus said with a small bow.

"I see; maybe we should call your father," their mother said, looking at her husband.

"I think your right," Alexander laughed.
