UNDERWORLD

"Are we there yet" whine a white haired little girl to her Grandfather siting next to her in their own car en route to Lord Beelzebub's Castle.

"Patience Sirius, we will get there in time to get your Evil Pieces" Said the elderly man to his granddauther. The said granddauther is currently bored in her mind.

'Why cant we just teleport to the Castle already. Instead we get to ride a train. Who needs tradition you old man' Glares Sirius to her Grandfather.'

Sigh"We cant just teleport to Beelzebub's Castle Sirius because riding the train to get something from a Maou is a tradition of ours so lets be patient and wait our time before we arrive" The Grandfather told her granddauther with a tired expression.'

'What the hell. Old man are you a mind reader. Maybe I'll train mind defense after we get my evil pieces' thought Sirius with a shocked expression.'

"No you silly girl I am not reading your mind, its just your expressionis telling me that much. And you should be better to hide your expression" the old man told Sirius with an amuse smile in his face.'

"Whatever Grandfather" Sirius said, and turns to the window of the train.

Currently both Zekram and Sirius is inside a train in a luxurios cabin on the way to Ajuka Beelzebub's Laboratory or his castle where Evil Pieces are given to young devils.

"Shhhhhhh" The train stops "Lord Bael we are now at Lord Beelzebub's Castle, thank you for your patronage." The speaker in the cabin stated.

"See Sirius just a bit of patience now that we are here to get your Evil Pieces." The old man told the girl.

"Lets go lets go quickly" exclaims the young girl to her grandfather to quickly steps up her old man's pace.

"Yes yes" mused the old man in the behaviour of his granddauther. 'Eager to get your Evil Pieces ahhh youth' thought the old man.

"Quite the child are you young one, such a large amount of mana in a child." Said a green haired man then the said man proced to face Zekram. "Lord Zekram how are you?" Greet the man.

"I am quite fine Lord Beelzebub. My granddauther here is quite the surprise isnt she." Zekram greet and told the other man.

"Yes, certeinly she is. She has an abnormal amount of mana for someone so young, and the reports of the accident is accurate to say at least. But alas I also see untaped potential is someone so young" said Lord Beelzebub with a face worthy of a Maou.

"She is quite the child prodigy of the Bael Clan" Zekram told the other man, and then turned to his grandfauther. "Go on intruduce yourself" continue Zekram.

"Nice to meet you Lord Beelzebub. I am Sirius Esther Bael" Sirius intriduce herself to the man.

"Yes nice to meet you too Sirius. I am Ajuka Beelzebub, today I will give you your Evil Pieces for you to recruit a peerage for yourself" inform Beelzebub to the Grandfather-granddauther duo.

"Now then lets procced to my laboratory where Young Siruis here will get her Evil Pieces." Lord Beelzebub told his company.

"Pls. follow me to my lab." guide the man.

-----

Ajuka's Laboratory

"Here we are this is my laboratory" Lord Beelzebub hosts his guest to his laboratory.

"Thank you for having us in Lord Beelzebub"

Thank Zekram to the other man.

"Thank you Lord Beelzebub we are in your care." followed Sirius to thank the Maou.

"Nonsense, pls go on we are here to get Sirius here her Evil Pieces" the Mauo told the Bael.

"Otherwise Thank you pls. we are in you care as you are to us" Zekram told the Maou.

"Yes, now then Sirius pls procced to the pedestal and put your hand to the pedestal while feeding it mana inside" the Maou told Sirius.

"Yes" Sirius did what is instructed to her. And put out her hand to the pedestal and feed it with her mana.

The pedestal then glow in an abnormal folor then after a few second the color shifted to a lavander colored energy, after a while feeding the pedestal with energy the pedestal then no longer accept mana from Sirius and the lavander colored glow died down.

"That is unexpected!" mused the Maou out loud.

"What is unexpected Lord Beelzebub?" Zekram ask the Maou.

"Lord Zekram the radiance that we saw is mostly the result of a mutated Evil Pieces. But to see the radaince that shine after feeding it with mana" the Maou told the grandfather.

"So it means that Sirius will get a mutated Evil Pieces." Answer Zekram his own question. With a shocked expression.

"Yes, mutated Evil Pieces is definetly present in her pieces" the Maou told Lord Bael in an amuse tone

The pedestal then release a light that hits Sirius in the chest. Then she glow violet and her Power of Destruction lash out for a second before the light died down.

"Woah" Sirius exclaims in schock "what was that light?" question Sirius to both the man.

"That is the king piece that flew to you Sirius, the king piece lets you connect the pieces you have and its abbilities you give to your peerage. Like promotion in a pawn."the Mauo answers the Question.

"Ok. Lets see my pieces" muse Sirius as she opens the box where her Evil Pieces resides.

As Sirius opens the box a light shine out then she procced to see her pieces. Both Zekram and The Maou watch her in anticipation of her pieces.

"Woah" exclaims Sirius again. "Half of my Evil Pieces is mutated" Sirius told both man in the laboratory.

"As expected of my granddauther, you truly lives up to the Child Prodigy of the Bael. Good Job Sirius."The old man praises Sirius.

"The queen is mutates along with a bishop a rook a knight and four of the pawns. Amazing so much potential"exclaims the Maou with glee.

"It is as expected to Sirius, she is a Prodigy after all" boast the old man.

After the event that transpire in the laboratory both of the Bael told the Maou their goodbye and procced to go back to their home.

"This is not reassuring at all. A prodigy in the Bael clan after a failure deemed by Zekram. I hope she can see through the schemes and plots made by her own granfather."Mused the Maou to the horizon.

"I hope that too Ajuka" a voice replied to the green haired Maou.

A crimson haired young man with green eyes with an arocratic clothes he patted the green haired Maou in the shoulders.

"Sirzechs your here" he replied to his freind.

"Yes Ajuka, I am quite afraid of what Zekram may do to her granddauther. More importantly the talent she posses, the power she have." Mused the crimson Maou.

"Yes she has the potential. A genius in one on thousand years. But power what are you talking about Sirzech?" Ask the green haired Maou to his freind.

"Power as it is Ajuka. Remember the Familiar Forest Incident before?" The crimson Maou ask the green haired Maou.

"Yes quite the destruction on a part of the forest, but isnt it expected of the Bael's Bloodline limit. The Power of Destruction like yours and rias." Answers the green haired Maou at his freinds question.

"Yes that is as expected of the Power of Destruction. But the time that it happend I felt the Power from when I was still sleeping. Ajuka I felt it, It woke me up."

The crimson Maou told his freind and continue."Then after I woke up I did an Investigation and what I saw and felt in the aftermath was terrifiying." Laces with serius tone the Crimson Maou rold his freind.

"What did you felt?" Asked the green haired Maou feeling the seriousness in atmosphere where the conversation is heading at.

"The Power is potent. Just like mine and Rias our Power of Destruction is a bit watered down. And when I compare our potency to Zekram's granddauther, it would be like comparing to Shiva's of the Hindu its as potent as one of the primordial chaos. I am quite afraid of the future right now." The crimson Maou stated before his freind.

"I see......And i get it that you have a plan or a backup plan set in motion before this time?" the green haired Maou hopefully asks if there is a plan.

"To be honest no. I dont have a plan right now. And I think you and I will have to talk it out ourselves" answer the crimson Maou.

"I Hope she can see thru the scheme and plot of that old devil" Ajuka Beelzebub stated again.
