A boy at the age of 17 exits the video he is watching on his phone as he keeps walking towards the school. He can hear the hushed whisper from the students as he reaches the campus. He sighs as he enters the school.

Kuoh Academy

He is 6 ft. tall, slim but toned. His most noticeable features are his green eye color and his scarlet spiky hair. It is clearly shown the mixture of his parents.

" Oh my God! It's Ryu-senpai"

" He is so handsome!"

" Kyaaa!! Senpai! Notice me!"

'Great. Another boring day' Ryu mutter to himself as he enters the campus.

Time skip

Ryu is leaning against the railings on the rooftop observing everything from the ground. He watches as two members of the churches are fighting against Kiba and Issei. And the two are completely lost in the battle.

" I can't believe that the Excalibur is reduced into this kind of weapon. What do you think? Eileen?" Ryu asks the girl at his side. The girl is the same age as Ryu but has light blue hair, brown eyes, and a tattoo on her right eye. She is also observing the fight beside Ryu.

" No wonder mother wants me to retrieve the fragments. She is pissed when the legendary sword was made into this. And more furious when she read the report regarding the experiment made. The church knows how to hide the incident" Eileen answers her 'uncle' as they watch the match end.

" Hmm. So nee-chan sends you here. Are they also here in Japan or you just went here alone?"

" I came with them though they told me to meet you here while they meet grandma and grandpa to the base." Eileen answer. Ryu still feels weird that Eileen is the same age as him but she is his nephew. Sometimes, he doesn't question his heritage anymore.

" Good luck retrieving the fragments. It will be very hard since both sides are very stubborn. What is your plan? since it's your mission."

" I plan to observe them. The fragments are still not complete. According to the report, Kokabiel is planning to merge the fragments, which means that he will need to collect the fragments. I will be waiting for the right moment to take it."

" Agh. I'm so fired up to fight. I thought we are gonna take it by force." Ryu pout.

" Why don't you train with your father. From what I heard, you two always spar." Eileen smirks seeing her uncle pout more.

" He is busy right. And besides, I always lose. I can't wait for the family gathering so we can fight each other." Ryu grin as Eileen just shakes her head and smiles at him.

" Me too uncle"

" Don't call me Uncle! We are the same age!" Ryu shouts glaring at Eileen who is smirking at him.


During Kokabiel's Battle

" God is dead! It wasn't the only four satan that perished in the great war. God was also killed!"

Everyone on the battlefield stares in shock at Kokabiel's declaration. They can't believe it, even the devils are in shock by the news as Kokabiel declares his desire to start another great war.

" I will take your head and show Lucifer and Michael that the fallen angel reign is supreme.!" Kokabiel declares laughing madly.

" You've got to be kidding me," Issei said stepping forward. "

Your spouting nonsense about the war when you just interfering in my dreams to become Harem King!" Issei declares shocking them. Rias reprimanded him and offer him a reward if he defeats Kokabiel.

Then suddenly the White Vanishing Dragon came and beat Kokabiel easily that shock the others. Albion and Ddraigg talk before they heard someone clapping stopping them.

They look at the source of the sound when they saw two figures wearing a cloak and mask. One of them is holding a staff while one of them is the one who is clapping.

" What a great show." A female voice heard from them as she approaches them. "Congratulations. You stop another war from starting" She spoke.

" Who are you?!" Issei shouts in shock.

" Just no one. I'm just here to retrieve an item." She answers as she stares at Kokabiel's state with approval.

The White Vanishing Dragon looks at the new arrival and grin feeling their aura. He dashes at them to attack but the one holding staff just defeats it with his staff. He tried to use Divide but a shock when it didn't work.

" Your power won't work on us so don't even try it," The woman said at Albion host's side. The man decides to kick Albion's host sending him away.

'Strong' Albion's host thought as he stares in shock at the two arrivals. And it also causes the devils and two members of the church to stare in shock witnessing how he handle him easily.

" Who are you?" A voice can be heard from Albion's host.

" It is not time for you to know yet."

The woman took the Excalibur fragment re-equip it. Irina and Xenovia stare in shock seeing the Excalibur vanish from the woman's hand.

" Where is the Excalibur?! It belongs to the church!" Xenovia argued as the woman look at her.

" Excalibur does not belong to the church. And it's not supposed to use in vile ways like this. The Guardian sent us here to retrieve the Excalibur" Irina and Xenovia almost choke hearing her explanation.

" The Guardian? What does she mean by that?" Issei asks confused seeing them looking in shock.

" The guardian is the one who chooses the rightful owner of the Excalibur. It is said that God gave the Excalibur to them so they can choose and train the next owner of Excalibur. It is said that they are the one who trains King Arthur." Irina explained.

" We thought the guardian is a myth. Some of the church records, they alter the origin of Excalibur since no one saw the guardian. But if they were sent by the guardian here to retrieve the fragments means they learn of the true state of Excalibur" Xenovia answer. After all, no one knew of the real state of Excalibur aside from the church.

" That is true. Imagine our surprise when the most legendary sword for humanity is reduced into this" The cloaked woman said as she turns around.

"Goodbye Devils and members of the church. Till we meet each other again."


Parents Day Commences

Ryu is glad that his parents are now busy nowadays. Don't get him wrong, he loves his parents but they will surely embarrass him especially when people will mistake her for his siblings seeing how young they look even in their old age though Ryu keeps it himself since he is afraid of his mom's wrath.

Ryu is walking towards the school when he caught a figure of a woman wearing some kind of a little girl. No. the presence he felt is not like normal humans. She is a devil, a powerful devil considering her presence.

" Are you lost?" Ryu asks startling the woman dress as a little girl. Her eyes widen seeing Ryu more specifically his hair.

" Wow! You have the same hair color as my best friend Sirzech-chan!" The little girl exclaimed.

" Um. I don't know this Sirzech-san. So can I ask again if you are lost?" Ryu asks

" Oh right! I'm looking for my little sister So-tan! I don't know where she is" She exclaimed.

" Oh. And this So-tan? Does she have a full name? I will help you find her." Ryu offered.

" Really?!"

" Yeah."

" Yay! Her name is Sona Shitori" She said making Ryu nod.

" Okay. She may be in her classroom or the student council room. I can take you to her." Ryu said.

" Thank you! Etoo... What is your name?" The little girl asking making Ryu facepalm.

" My name is Ryu Belserion. Nice to meet you... Shitori-san" Ryu said not knowing her name but since she's Sona's sister then she called her by her last name.

" My name is Serafall... But call me Levi-tan" Serafall makes a magical post making Ryu sweat drops.

"Oh... Okay L-Levi-tan" He said hesitantly as he was attacked by a sudden hug from Serafall.

" Yay! Levi-tan makes a new friend" She makes a V sign as she drags Ryu inside the school.

Ryu can hear the whisper from the students mistaking Serafall as his girlfriend and her outfit which they know as a magical girl. They stare in awe as the duo walk in the hallway with Ryu leading her to the student council room when they catch a glimpse of Sona along with Rias, Akeno, Issei, and another 3 unfamiliar people in the hallway.

" So-tan!" Serafall shout running towards Sona who has a look of shock. Ryu who is being held by Serafall in his arm is being dragged along with her.

" O-Oi!" Ryu shouts in protest as he releases himself before Serafall can include him in hugging Sona.

" Nee-san!" Sona yelp as Serafall hugs her sister closer to her. Ryu can hear the devils introduce Serafall silently since they saw him in the vicinity.

" So-tan. Meet my new friend Ryu-tan" Serafall introduce making Ryu look at her in shock

" R-Ryu-tan?" He asks in shock. He is not the only one in shock, even the devils around him are in shock.

" N-Nee-sama. Where did you and Ryu meet?" Sona asks in shock...

" I met her outside the school. She is lost so I help to look for her sister which is you" Ryu explained. Sona nods at his explanation. But still, shock since even if Serafall is friendly, she is not this kind of close to humans.

" Look! He has the same hair as Rias-tan and Sirzech" Serafall said appearing once again beside Ryu.

" Yeah. He kinda has the same hair color as us. Haha. Perhaps we are related to each other." Sirzech laughs as he looks at Ryu. He offers his hand and introduces himself and his father.

But what caught Ryu is when the silver hair woman named Grayfia introduces herself to him. Grayfia's aura seems familiar. And it reminds him of someone he knows very well. Ryu was snap out from his thoughts when Issei called him.

" Ryu-senpai. Are your parents not gonna come in Parents day commence?" Issei asks not seeing Ryu's parents.

" Don't worry. I told them not to. I'm glad that they listen since sometimes they embarrassed me" Ryu said sheepishly, knowing his parents, they will surely try to embarrass him. He also doesn't want to explain to everyone why his parents look the same age as him. Ryu heard a whisper from Sona and Rias how lucky he is.

" That's okay. Ryu-tan have me" Serafall said making Ryu look at her in disbelief.

" Eh? Aren't you here for Kaicho?" Ryu asks in shock.

" Don't worry. I will be with So-tan" Serafall said.

" B-But... It's-" Ryu felt a shiver when he heard a shot coming from the hallway. He looks behind him seeing two people he didn't expect.

" Ryu-chan!!!!" A shout can be exclaimed in the hallway. Ryu steps back but was hold back when Serafall didn't let go of his arm.

" Ek! What are they doing here?" Before anyone can ask what he meant, he was tackled into a hug by a woman with orange hair.

" J-Juliet! What are doing here?" Ryu said in shock. Ryu grew a tick mark when he heard Issei speak.

" Ryu-senpai! You didn't tell me you already have a girlfriend!" Issei said pointing at Ryu in accusation.

" Shut up Issei" Ryu growl as he tries to remove Juliet from hugging him.

" Let go of Ryu-tan!" Serafall shouts clinging to his arm as she pulls him closer to him.

" Who are you?!" Juliet glare at Serafall she glares back.

" I'm the great Levi-tan and Ryu is my friend," Serafall said as she presses her chest in Ryu's arm. Issei can be heard crying at the side.

" Juliet. What are doing with Ryu-sama? Release him at once." Heine said appearing behind them. She is the opposite of Juliet and has dark blue hair.

" What a bummer" Juliet whine as she releases Ryu from her hug. Ryu sigh in relief forgetting to breathe again.

" Heine. What are you doing here? Wait... Did mom and dad came?" Ryu suddenly becomes alert. The two watch him amused.

" You don't need to worry Ryu-sama. Your parents didn't come through my lady asks us to come instead and pick you up after your class." Heine said.

" Oh. Okay... J-Just you two don't embarrass me." Ryu mumble as he introduces Juliet and Heine who are working for them. The two know they are the devil and keep their guard up. They look at Grayfia and has a contemplative look on their face but nod at her as they lead their master back to his classroom leaving a shock, confused and pouting devils.


Time skip

Ryu and Eileen walk inside the large building and went to the highest floor. They enter the room and saw their parents inside talking to each other. When they saw each perspective kids. They hug them much to the embarrassment of the said children.

" So? How did your observation go?" The salmon hair man asks wearing a business suit.

" The meeting is a success. The 3 factions are now united though they face some problem" Ryu reported.

" Problem?" a woman with scarlet hair ask with a confused look on her face.

" Yes. Some terrorist named Khaos Bridge interrupts the meeting. But they are not successful. Albion and Ddraigg fight each other with Albion's host betraying Azazel" Ryu answer.

The man shook his head hearing the report. " I wonder how she's gonna react if she heard about this"

" She will be devastated"

" Mother. Can I ask a question? What will happen to the Excalibur?" Eileen ask her mother who smiles at her daughter

" We retrieve one of the fragments from my student's descendants. And we plan to bring Excalibur back to its original form."

" Ohhh... Then, who will it be its new owner?" Eileen ask.

" I'm still looking for it... We will see in the future"

" And what are your opinions regarding the treaty?" The scarlet hair woman asks the children.

" We think they manage to work together despite their difference. Though the balance is more at advantage of devils. They have a powerful human that they reincarnated into their kind." Eileen answered.

" They are powerful but their mindset is still for a selfish reason. Though I have some concern regarding their reincarnating humans" Ryu added since he's been observing them since he started going to school.

" What is it, Ryu?"

" I observe 2 devil reincarnating humans into devils. One of them is being offered which is no problem for me. But the other one is letting someone die and save him by reincarnating into the devil."

" What? Did she assassinate one of the humans so she can reincarnate them into the devil?" Eileen asks angered at the prospect of someone letting a person die.

" No... She knows that there are fallen angels that lurking in their territory but she let them interact with humans and be killed." Ryu clenches his fist remembering the death of the humans. Ryu felt his father hand calming him down.

" I'm not that surprised. Even if they are a new generation of the devil, they still have greed inside them. That's why we will not let them do as they please with our kingdom." Ryu stare in shock at his father's implication

" W-What do you mean? Dad"

" Now that the 3 factions are united... It is time for the Alvarez Empire to rise"


Thank you for reading my story. I will try to update as soon as possible.

DxDLordKing: Thank you for reading and leaving a review.

The reason why I didn't put any details like the perverted old man because I want it to be a mystery. Hehe...

My first draft was supposed to show what happens during the war but I change it since it will ruin the surprise when the faction discovers the Alvarez Empire.

That is also the reason why the time skip has a huge gap cause I want to insert their experience through flashback.

It's fun when the reader has to guess who is part.of the Spriggan 12 and who the child is base on a little clue.

And In regards to Irene and Natsu's relationship. The two develop a student-teacher relationship that evolves. And the flashback will be in the future chapters.

I appreciate the review!

I will try my best to improve the story more.

I think anyone already knows who owns AE Tech. The history of AE tech will be in future chapters.

You can guess who's Ryu and Eileen's parents are. Hehe.

Thanks for reading!

Till the next chapters!
