"Oh that sounds nice." Sirzechs said coming down the stairs.

"Onii-sama." Rias said.

(Hyoudou Residence)

"Oh it looks like you've outdone yourself Jin!" Red says.

"Looks exquisite." Zeoticus says.

"Made the finest in the neighborhood." Jin said.

"Cheers!" The four men shouted. Asia and Tiamat were washing dishes while Rias and Issei were sitting at the table drinking some punch. And said men were watching Jin's recording of Issei and Asia in their class.

"Asia Issei, you both look so good on camera!" A druk Jin said.

"How embarrassing." Issei and Asia said.

"Now let's watch the recordings of Rias." Zeoticus said.

"Oh you have recordings of her as well?" Jin asked. Just then he played his recordings of Rias in her class.

"Oh why me?" Rias said solemnly.

"Oh and Rias, you can now release the bishop from that room." Sirzechs said.

"Rias, you have a bishop?" Issei asked.

"Yes, but we sealed her away because her power was not able to be kept under control." Rias said.

(Time skip)

After Rias, Issei, Asia and Tiamat went to sleep. The four men downstairs were discussing something.

"So Jin, your nephew is something else as are you." Zeoticus said.

"Oh?" Jin said.

"Yes we know that he holds back a significant amount of power, and as do you." Sirzechs says.

Flashback

(10 years ago)

"Alright." Issei said. "Ahhhh!" Issei screamed as the gauntlet shind.

{Class up: Vanguard!} Ddraig announced, just then Jin was covered in a bright green light, then it faded a few seconds later.

"Ddraig, what was that?" Jin asked.

{It's a new ability that my host unknowingly created. It's called "Class up" and it's similar to the evil piece system the devils use. Just like their system it gives them certain roles, and the role I gave you was (Vanguard).} Ddraig explained.

"So what did this role do?" Jin asked.

{It gave you a tremendous power boost as well as some other things. Your full power now rivals Shiva the hindu god of destruction, you're Immune to any human diseases and your resistance is off the charts! And as a bonus you can heal wounds no matter how grave and even with the highest of curses inflicted on them! But your overall ability, which is dragon-god class, is the exclusive ability to calm down Issei. I gave you the power to do that because of that little display he had with the evie earlier.} Ddraig explained.

"I see… Well I assure you that I will adhere to this role you've given me Ddraig." Jin says

(Flashback end)

"Well you're right about that, we do but we will not talk about them given that there are greater things that we worry about." Jin said.

"I see, but I must ask this, are you or Issei a threat to any of us? And I'm not just referring to devils, but I mean everyone, any of the other factions, religions or pantheons?" Zeoticus asked.

"Well what I will tell you is that we're completely neutral in that regard with a few other things. I myself am exceedingly powerful but I come out as not a hostile threat, Issei however…." Jin said.

"Yes?" Sirzechs said.

"Well he's initially neutral but, there are times when he can explode if he's pushed far enough, this is due to both his power struggle and his mental struggle which he gained 10 years ago when he was still a child." Jin revealed.

"I see. But the question is what usually triggers this?" Sirzechs asked.

"Well, back then but rarely now, a mental condition from what happened to him all those years ago. Another one would be that power struggle I mentioned earlier but that only happens when he uses a lot of power. And finally when he encounters certain people as well as a certain species, irrational people like Riser would fit that description of people I mentioned. As for the certain species….I won't tell you about them yet, but what I will tell you is that they're none that any of you are familiar with." Jin revealed.

"Alright then, we shall be on our way now." Zeoticus says.

"Good, I hope we meet again soon." Jin says. Just then they open a magic circle and teleport away.

"Well Jin Ima hit the road now. I hope you're taking good care of Issei right up there. He's really a good guy but I don't want his experiences or his trauma to change him." Red said as he teleports back to the dimensional gap.

(Evie Etoulde)

"My lord we got the data back from Riser's fight with the boy, Issei he won however when Riser revealed that we were the one's one gave him the power Issei fought him in another world, but we were still able to calculate through the aftermath as you can see here." The evie explained showing Regalzeva the data.

"Fascinating! At least now I know that this battle I'm setting myself up for will not be a waste of time. Also prepare the army for an attack on another planet, then after that we shall go to draconic deus." Regalzeva said.

"Yes my lord." The evie said.

"Extraordinary. He even surpassed the expectations of the experts, I'm going to enjoy this. But for now I'll tell my sister that the power she gave him was no match for that boy and I will send Melvazoa the data of the boy." Regalzeva said.

Earth

(Next day)

Asia Issei and the rest of the ORC were at a chained up door in the old school building that Issei and Asia hadn't noticed before.

"Well it's time to break the seal. Issei do you want to do the honors?" Rias asked. Issei compiled by breaking the seal with his own magic.

"Ahhhhh!" Someone screamed from inside the room.

"Alright now. It's time to come out." Akeno said, lifting a coffin, revealing a girl inside.

"But I don't want to!" The girl said. She had platinum blond hair and pinkish-violet eyes. Her hair is styled in a short bob cut with several small fringes over her forehead, and she has pointed ears. And she is wearing the girls uniform of the school.

"Her name is Gasper Vladi, she is part of my peerage and my bishop. She is a freshman at Kuoh academy. And she was half vampire, half human before she was reborn.

"Well hello there Gasper my name is Issei hyoudou. Nice to meet you!" Issei said.

"H-Hi Issei-senpai." Gasper said.

"So what is your sacred gear? You smell like you have great potential." Issei asked, somehow calming down the bashful little girl.

"I-It's called… the Forbidden Balor View." Gasper said to Issei.

(Club room)

"So I probably owe you two an explanation, since Gasper can't control her power. It was ordered by onii-sama to seal her away, but it turns out her power naturally refines itself over time, giving it the potential to be a balance breaker." Rias explained.

"So that's what I sensed." Issei said with both Gasper and Koneko on his lap.

"Oh and Yuuto, come with me. Onii-sama wants to know more about your balance breaker." Rias said which Kiba complies by coming with her. "Oh and Issei, can you train Gasper while I'm gone?" Rias asked.

"You can count on me Rias." Issei replied as Rias disappeared.

(Outside)

Koneko was first at training Gasper, she chased her around the old school building with garlic.

"Well this looks like it's uh…Going well." Issei says awkwardly.

"Ah, it seems the satan's family is playing games out here. Nice sight." A man in a robe says. "Hello devils, and the red dragon emperor." The man said.

"Azazel." Koneko said, now on guard.

"Relax, and besides even the rest of your peerage were here you wouldn't stand a chance." Azazel said.

"Yeah stand down, I can sense his power, he's not lying." Issei said.

"But Issei, what about you? He might attack us." Koneko says.

"It's fine he won't do that in devil territory. Plus even if he does attack I'll deal with him." Issei says.

"Well I know you're strong and you're right about the term of me being here. However, are you sure you surpass me?" Azazel asked.

"Do you want to have a friendly spar in my barrier to prove it?" Issei asked innocently.

"Fine by me, plus I get to personally see you in action." Azazel says in interest. Just then Issei surrounded the old school building in a barrier, the ground and other structures looked completely black while the skies looked green. "So are you ready?" Issei asked.

"Yes, now come at me." Azazel said. But at a speed that not even Azazel could read, Issei punched him instantly, knocking him out to everyone's surprise. Then Issei dissipated his barrier and woke up Azazel. "Alright, I have to admit I didn't see that coming." Azazel admitted.

(Inside)

After Azazel left Gasper went back inside her now unsealed room. While Asia and Koneko walked home. They asked Issei if he wanted to come as well but he said he's not giving up on Gasper.

"Hey Gasper, are you scared of your gear? I'm scared too, everytime I use too much of Ddraigs power I begin to lose myself. I feel like I deserve all I'm about to do even though I'm doing bad things, but I continue on so that I don't witness the horrible things that I've witnessed before." Issei says.

"But that power can take everything away from you, so why do you use it?" Gasper asks.

"Well before I even unlocked that power I already lost something dear to me, but I want to utilize this power of mine so I can make sure they never do it again." Issei said then Gasper opened the door.

"They?" Gasper said.

"Oh well….That's a tale for another time, but you're going to be with us from now on.

"But I'll just hold everyone back." Gasper said.

"No you wont and besides, you're my friend, and I'll help you!" Issei says.

"Issei-senpai." Gasper says

(Scene skip)

Issei and Gasper were discussing their goals when Kiba walked in.

"Well done Issei-kun." Kiba said.

"Oh hi Kiba, we were just now discussing training." Issei said.

"That's very nice, tell me the results after you're done!" Kiba said.

"Alright Yuuto-sempai!" Gasper said.

Scene skip

(Shrine)

After Issei gave Gasper a few rounds of training which were going well for her. Rias came back and told Issei to follow Akeno to a shine. After they reached the top an angel appeared out of a flash of light

"Nice to meet you Issei, I am the leader of the angels." The man introduce but Issei quickly figured out that it was Michael. Then the group found themselves in the shrine building. "Hyoudou Issei-kun, this is a holy sword meant for killing dragons, Ascalon. I would like to give this to you. I hear that you're very powerful, so I'd like to give you this sword to help you out." Michael said.

"Ddraig you ready?" Issei asked the dragon.

{Yes, just hold your hand out.} Ddraig instructed. Just then as Issei compiled the sword merged with the gauntlet.

That's it for this one guys, see ya!
