In the forest around the abandoned Church, Grayfia Lucifuge is standing at the starting point where Kisuke casts his Kidou. The terrain already returned to its former appearance with the help of magic. Grayfia has been coming to this place multiple times to inspect it because she wants to look something else other than her initial findings.

Grayfia is checking the lingering mana that the beam left. She has done this already several times but still can't believe the result of her investigation, "The attack composes two types of energies, half is mana and the other half is soul power... Who the hell is insane enough to use his or her own soul to fuel a magic attack. I can only think of it as a suicidal spell that brings down the opponent with him."

Just after inspecting the place again, Grayfia suddenly heard a heartbeat. It is soft but very clear, then a sudden wave of oppressive dragon aura came from nowhere and disappeared just as fast, "What!?"

Grayfia exclaimed and looked around to find its source but failed. She flew up to get a vantage view of the whole town. There she saw all sorts of beings flying up and looked around the town, 'Did they also hear that heartbeat? So it encompasses the whole town? How strange, I felt that it's only beside me. And that aura... A dragon's? but the only thing qualified as a dragon in this town is the Boosted Gear... I have to check him...'

Grayfia flew across the sky while hiding her aura. She landed on the roof of the Hyoudou residence and took a peek inside using magic. Grayfia saw that Issei Hyoudou and Asia Argento are looking around confused. She focuses her attention on Issei's left arm where the Boosted Gear resides. She didn't notice anything out of place but just to make sure, she scanned it with her Demonic Power.

Grayfia still couldn't find anything, but after a few more seconds of inspecting, something tugged on her Demonic Power and an archaic voice entered her mind, "Little Devil, what is your purpose?"

Grayfia was shocked and was about to disconnect her power, but before that happens, the voice resounded in her mind again, "Don't panic. I meant no harm. Something came up that's why I decided to talk to you."

Grayfia stopped her intended action but still stayed vigilant. She didn't speak out loud but she replied using her thoughts, "Are you one of the two legendary Heavenly Dragons?"

"...Yes."

"Excuses me for my rudeness. A very brief dragon's aura spread throughout the town and you and your host are the only ones I know capable of producing something like that. So I inspected it immediately. I'm sorry if I disturbed your rest." Grayfia spoke formally after the voice confirmed its identity.

"...Were you able to hear the heartbeat?"

"Yes. It came just before I felt the aura."

"So it really wasn't my imagination..." The archaic voice softly muttered.

"It wasn't you, sir?" Grayfia asks.

"Haahh... I guess I can tell you about it." It let out a huge sigh and then continued speaking, "There were actually two heartbeats that resounded at the same time, and the aura that followed it signifies the birth of two dragons."

"Two dragons... but shouldn't be any other dragon present here."

"That's also one of the mysteries as too should have felt something if a dragon is nearby."

Grayfia didn't speak further and just waited for the archaic voice to continue.

"But really... how strange... Little Devil, do you know how dragons are born?"

Grayfia tried to recall the information from the books about the dragons and now also find it strange, "There should be a beat every one minute with a total of three beats. The first beat is the weakest and the last beat is the strongest. A few minutes has already passed, but there is only a single beat."

"And the aura suddenly disappeared. Someone must have blocked it after it spreads for the first time."

"Fuuhh... Such a shame. Witnessing the birth of a dragon should be a fine experience." Grayfia sighed, not understanding the archaic voice's dilemma.

"You're making light of this situation."

"What do you mean, sir?"

"A dragon's birth is accompanied by their first three heartbeats but how loud it determines its natural potential. A normal dragon's beats can't be heard without listening to it intently. A superior dragon's first beat can be heard one meter around it and the third beat can be heard ten meters around it. Now imagine the potential of these two dragon's first heartbeat. If my guesses are right, the second beat would resound throughout the whole country and the last one would be heard throughout the Human world."

Grayfia was speechless at its words. It took one whole minute before she could respond again, "... How strong are those dragons when fully mature?" In her mind, she's calculating how would the current Underworld be disrupted by these dragons, 'From the way he speaks about it, these two dragons should be on the same level as them, the Heavenly Dragons... A birth of Heavenly Dragons in flesh and blood, how will it affect the current thread of the world?'

The archaic voice guessed what she is thinking and said, "No. Those two aren't on the same level as both Albion and me."

After hearing this, Grayfia sighed in relief as she and her husband don't want additional variables to these turbulent times where war can easily break out.

Seeing her reaction, the archaic voice laughed out loud, "Ahahahaha!!!"

Grayfia was shocked at his laugh and thinking if she did something worth laughing, 'Dragons are really strange, especially the strong ones.'

The archaic voice is still snickering at her but Grayfia didn't mind it, because, even though it's currently sealed, this dragon is a lot stronger than her in its heyday.

"Little Devil, I forgot to tell you something." The voice calmed itself and spoke again.

"What is it, sir?"

"The auras that accompanied those heartbeats can only remind of both Great Red and Ouroboros Dragon. I don't know if they are their spawn or what, but a thousand years or less to the future, we may have two additional overlords of this world. How mysterious, someone would actually hide the birth of these two." The archaic voice then released Grayfia's Demonic Power and went back to inactivity.

"... ... ... ...W-WHAT!!!?" Grayfia then notices that she was already disconnected from the voice. She tried inserting her Demonic Power to Issei's left arm again, 'Please, please answer. Sir!... Dammit!' She gave up after a few minutes because she knew that the dragon won't answer any further questions.

Grayfia took off and flew around the town while hiding her aura. She kept scanning every building she could find to at least get some clues to the new dragons' whereabouts and the mysterious guy who actually went and tried hiding it, 'What is this guy planning? Why would he hide those two dragons that can be on par with those legendary beings? Is he trying to take over the world?' Such questions kept rising up from her mind as she searches the whole town.

She eventually reached the Urahara Household and Candy Shop. Grayfia noticed that Sona, her servants, Rias servants, the boy she encountered earlier and two other humans. One of the human women is somewhat familiar to her but she couldn't think about it now, 'What are they doing here? They are just having a lively conversation? I can ask Rias about it later. This isn't the time to observe them. I have to look for more clues.'

Grayfia then scanned the whole house and shop one time before moving to the next one.

After searching for the whole night, she found nothing and felt frustrated. She immediately returned to Underworld and report to her husband what just happened and the dragon within the Boosted Gear's words.
