Prologue

It was peaceful in the town of Kuoh. The town is devil's territory of Gremory Clan. An ususal and not normal group of people at a certain place on great importance.

(Hyoudou Residence)

Rias Gremory (High-class devil, King) and her peerage (Kiba Yuuto: Knight, Koneko Toujou: Rook and Akeno Himejima: Queen), Tiamat (Dragon King) and Mina Tepes (Queen of all vampires) and Akira Kaburagi Regendorf (Werewolf Protector) sitting on the couch. Mrs. Hyoudou placed on the coffee table, a teapot and several cups as she sits on another couch across of them.

"Thank you all to come and please help yourself some tea" said Mr. Hyoudou as he gets some tea and sits down next to his wife on another couch.

"You called all of us here. You are very worried or concerned about your son right, Mr. Hyoudou" said Mina Tepes as Akira gave her some stigma (food source for vampires).

"I'm very worried because Issei is born with one of thirteen Longinus mid-tier sacred gear, Boosted Gear that contains the soul of one of two Heavenly Dragons, Welsh Dragon - Red Dragon Emperor, Ddraig. Issei my son please show them" said Mr. Hyoudou as he takes another sip of tea.

"Ok, dad" said Issei as he summons the Boosted Gear on his left arm.

[Boost]

Rias sees the beautiful red spiked with green jewel gauntlet.

"Someone is trying to get their hands on the Boosted Gear from my son" said worried as he try to stay calm as he drinks his tea.

Rias feels drawn to Issei like love in first sight. Issei is captivated by Rias's beautiful blue-green eyes and her crimson-red hair like the color of royalty and color of blood. Rias beckons Issei to sit next to her. Issei got up and sits next to Rias. She hugs him as he hugs her back. Rias gave Issei a leaflet with Gremory Clan seal with something written by her. She whispered in his ear that he keeps the leaflet close to his heart.

"I know who is trying to get the Boosted Gear. It is the Fallen Angels Faction. They entered my territory and disrupted my business that they deserves a million deaths" said Rias as she hugs Issei tightly. She lightly kissed Issei on the forehead.

"That's why I called all of you here. If the Fallen Angels remove the Boosted Gear from my son, Issei will die. I want Issei to continue to live with the person he loves" said as he and his wife sees Issei is liking Rias.

Akira who was outside for fresh air hears footsteps far away and takes a look at a group that turns around the corner. He smelled the scent of Fallen Angels. Akira rush inside to Mina Tepes and whispered into her ear that a group of Fallen Angels in disguise is heading this way.

"Akira, are you sure the group is Fallen Angels?" said Mina Tepes as she is talking to Akira.

"Hime-san, I can smell their scent strongly and definitely it is the Fallen Angels" said Akira standing behind Mina Tepes.

"Akira here has informed me a group of Fallen Angels are heading this way as I speak" said Mina Tepes got up.

Rias lets go of Issei and placed her hands on his shoulders.

"Be strong and powerful for me, Issei my love. We will meet again someday in the future" said Rias as she hugs him lightly and got up.

"I will, Rias my dear. I will come back to you and be together with you" Issei responded as Rias smiled.

Mr. Hyoudou got up, went up to Issei and placed his hands on Issei's shoulders as Mrs. Hyoudou stands beside him.

"Issei my son, go with Mina Tepes, Akira and Tiamat. They will train you to be strong and powerful" said Mr. Hyoudou as he hugs his son and lightly kissed him on the cheek.

"Come Akira, Issei, Tiamat. We better go now. Rias Gremory we will meet again" said Mina Tepes as a transportation magic circle appears under them and then disappears.

"See you all. Come my lovely servants, lets help Issei's parents fight Fallen Angels as Gremory Clan" said Rias as she and her peerage goes to the front yard joining Mr. and Mrs. Hyoudou.

(Front Yard)

Mr. and Mrs. Hyoudou standing firm and ready to fight to the end with Rias and her peerage.

The group of Fallen Angels led by long black hair down to her hips and violet eyes with large bust named Raynare.

"We came for the sacred gear" said Raynare under disguise.

"How dare you, Fallen Angels going after my son" said Mr. Hyoudou with anger that mass of power and aura surrounds him. He and his wife start transforming into their true forms.A large Western flame dragon with large red wings on his back and Eastern lightning/ice dragon.

'Issei's parents are humanoid dragons of Dragon Clan' Rias thought after seeing the first time.

(Vampire Bund - Palace)

A transportation magic circle appears, Mina Tepes, Akira, Issei Hyoudou and Tiamat arrives. Issei place the leaflet to his heart and thought 'Rias my dear please be safe for me.'

"Issei Hyoudou, Vampire Bund will be your new home. I will educate and train you to be fine gentleman with strength and power. Issei think of me and Akira as your mom and dad" said Mina Tepes with her hands on his shoulders.

"Ok, mommy Mina and daddy Akira. I want to be strong and powerful for Rias Gremory the one I love and in memories of my parents who protected me. Dragon King Tiamat train me to use Boosted Gear/Ddraig's power fully" said Issei with strong conviction.

"Issei, I'll be gladly train you the powers of Boosted Gear/Ddraig and the abilities of the dragon fully plus I will teach you one or two of my powers. Also I can be your familar if you want me to, so I can protect you and Ddraig" said Tiamat as she hugs him.

"Thanks Mina Tepes, Tiamat. When we start my training?" said Issei with determination in his eyes.

Mina Tepes, Akira and Tiamat sees Issei as special and with lots of potential. They all agreed Issei is ready.

(Front yard - Hyoudou Residence)

The battle was furious both sides have suffered losses. Fallen Angels lost 3 of their own. Raynare seriously injured and retreated for now but she will be back again. Mr. and Mrs. Hyoudou died but not in vain they know that Issei lives on. Rias and her peerage survived with little injuries. Rias thought 'Issei my love, please be strong and powerful for me. Come back to me someday that we can be together again and forever.'

A blue magic circle appeared and out is Tiamat. She looks around and sees two dragon bodies. The dragon bodies of Issei's parents. She went inside of Issei's house to gather Issei's belongings and other things into boxes. She put Issei's belongings and boxes into pocket dimension for safe keeping. Last thing she picked up both dragon's bodies and teleported to a unknown location. She created a wooden structure, placed both dragon's bodies, and lastly using her blue flame to light the wooden structure to burn dragon's bodies. (A/N: This is the way to honor both Issei's parents like Viking way to honor the dead warriors)

Issei's new life begins with Mina Tepes, Akira and Tiamat with lots of hard work and sweat to become what he wants to be.

That's the end of the Prologue. I try to recreate a scene from Vampire Knight Guilty episode 'Spiral of Collection'. It is like it closely. Please comment and favorite this story or me (OutstandAce170). I'm working on the next chapter. See you all.
