Author's Note – The fan fiction takes place after Shin High School DXD Volume 29 chapter when Issei was fighting against Angra Mainyu and in fan fiction he was saved by Rias. His condition was caused by the Alphecca Tyrant shooting a Holy Nail on Issei and striking Issei in canon and so in canon, Issei could no longer power his Sacred Gear by lewd thoughts. He could no longer use Dress Break and Pailingual in canon after the attack and he is embarrassed to think about breasts as he feels that those are not what high school students should think of in canon after the attack.


Issei thought about what happened before and the circumstances when he was expelled.

Flashback

Issei and others were gathered in the Occult Research Club hall and they were discussing what should be done about Issei.

"Issei would be a liability in matches if we continue to have him battle in Rating Games like Azazel Cup." Asia said.

"I think we could no longer use Issei well. We have tried everything but Issei has changed and his condition looks like he could be unrecoverable." Xenovia said.

"Issei, you say you can no longer think about lewd thoughts until the right age. We could wait for you to reach the right age and then since you might feel such lewd thought could be thought after marriage, we could marry later and then you can think in any way about me. Till then we need to let Issei focus on other things like studies." Rias smiled and said.

"Yes, till then I will try to be the best student!" Issei said with a smile.

"Polygamy is illegal in Japan." Koneko said.

"So the curse could be lifted after Issei marries Rias." Akeno said.

"Till then Issei would have to be kept from fighting. Since Issei does not enjoy lewd things anymore, the delusions inside his brain does not reach the realm of activation anymore and so he cannot use Dress Break or other techniques. Those techniques are important. So from now on, Issei would be retired from fighting in Rating Games unless we were almost going to lose and then we could try using him. When fighting against enemies, Issei should not fight unless all of us were down. We would call Issei only when it is necessary." Xenovia said.

"Issei would now be a decent man. So he might even not be able to do some Occult Research Club activities." Irina said.

"I never imagined that Issei would ever be decent. Since the Longinus shot a Holy Nail on Issei, Issei speaks like a decent man. No one is able to change Issei back to his original state. So we would have to wait till Issei marries Rias for the curse to be lifted." Koneko said.

"So just like how I was barred from participating in Occult Research Club, Issei would also be barred." Gasper said.

"Yes, club activities could distract me from studying. I need to study and be the best student! Ddraig, lend me your power for me to study!" Issei said.

"Yes, I will help you. Your name is no longer Breast Dragon Emperor, you are Red Dragon Emperor!" Ddraig said.

"This will cause fans to be sad and for my family to no longer make money! But this would have to be in a hiatus as Issei is no longer interested in Breast Dragon." Rias said.

"A hooded female Magician attacked Ise-kun's Boosted Gear with a nail made of holy aura. At that time, we could not confirm any injuries or effects on Ise-kun or the Boosted Gear itself... ...Well, as we all could see, the effect was huge. Ise-kun rejected obscenities." Asia said.

"Issei, you are the best!" Koneko smiled and said.

"The entire school is surprised that the Issei they knew is no more like that and now Issei is so different!" Akeno said.

"So it is decided. Issei would no longer take part unless it is necessary." Xenovia said.

Flashback End


Rias was thinking about Issei's situation while sitting in a chair next to the table in University.

Flashback

Rias asked Ravel.

"Ravel...I want to hear your opinion on this."

Ravel nodded and began to speak.

"...An attack which erased Issei's perversion... It was definitely the enemy's intentional goal. I think the reason for erasing Issei's perversion is to seal off his true power. To cut off the source of the Breast Dragon, which has made many miracles happen."

Ravel continued on while everyone was listening to her.

"I know that there are Alliance of Hell spies and Hidden Khaos Brigade supporters who have invaded our territory. They invaded us so they could attack at some point... They must have gathered some information that was beneficial to them, but they realized they wouldn't be able to defeat the D×D team. In such a situation, they chose to obtain information on a broader level, as if they were grasping at straws. And incidentally, they found information that was interesting to them."

"...Azazel's playfulness."

Rias said while narrowing her eyes.

In response to her words, Ravel-san nodded.

Rossweisse-san had her lips covered by her hand and her eyes were rigid.

"So...the hidden ones knew they could erase Ise-kun's source of miracles. Even Azazel-sensei's mischief could erase it only temporarily. But in the case of a Longinus with the ability to change the perception and concept of others..."

"They figured it must have been possible. Of course, I'm sure they also analysed the research left in this city by Azazel-sensei."

Ravel-san continued on.

Rias put her hand on her chin.

"...The new Longinus, [Alphecca Tyrant], is one of the Holy Relics...and its ability is based on the Holy Nail. It can generate power to control people in a particular area, and with the aura shaped in the form of a holy nail, this crown can be used to attack."

Rossweisse followed up to the conversation.

"...A crown made of sacred nails... You mean it's similar to one of the Holy Relics from Christianity, [The Iron Crown of Lombardy], but in the form of a control-type Sacred Gear...?"

Located in Italy, [The Iron Crown of Lombardy] was both a reliquary and one of the oldest royal insignias of Christendom. It's made with sacred nails, which were used when Jesus Christ was crucified. The emperor was said to have worn an iron crown like the famous Charles and Otto.

Ravel added.

"Researchers say that the real [The Iron Crown of Lombardy] has disappeared from history...but it may have been rebuilt by the Sacred Gear system...and incorporated into our current world."

It seems that the current replica of [The Iron Crown of Lombardy], after being modified a few times, was kept in the Cathedral of Monza.

Akeno then asked Rias.

"If I'm not mistaken, I heard that the first researchers of the Three Factions that confirmed the possessor of the crown Sacred Gear died."

Rias nodded.

"Yes, because it was an undiscovered Sacred Gear, they tried to negotiate carefully, but they lost control of themselves and committed suicide."

...I had also heard that information.

It was also said that there was a Sacred Gear possessor in a certain city in a region of Europe who ruled over all the people in the city. When researchers approached the possessor, it developed into a dispute, and in the end, it was said that they killed themselves.

Ravel said.

"At that time, only the crown seemed to remain. They tried to recover the crown...but it was shrouded in a holy aura and then disappeared somewhere. The next time, the energy signature of the crown was found in–"

Kiba jumped into the conversation.

"The British Royal Family?"

Usually, when the possessor died, Sacred Gears tended to disappear and return to the Sacred Gear system.

The same goes for any Longinus as well. It was then inherited by the next possessor, chosen at random.

This included cases like Issei, Vali and many Longinus possessors.

However, in some rare cases, the power of the Sacred Gear remained after the possessor died. Examples included the 'Holy Cross', which was a Longinus titled Chief Mourner's Crucified Stand of Purple FlameIncinerate Anthem.

Even if the possessor died, this Longinus would begin to move spontaneously, and it would then choose the newest possessor. Incinerate Anthem had changed possessors many times before, and now, Lint currently wielded it.

"It's just like mine."

Lint waved a purple flame from her fingertip.

A Sacred Gear which liked changing possessors...

Indeed, The Iron Crown of Lombardy seemed to be that case.

Rias responded with,

"But the ability of Alphecca Tyrant is different from the description... The ability to change the perception and concept of the person who was attacked by its sacred nail... Does that mean that the power has altered due to the change of the particular person?"

Koneko said.

"...It could be a sub-species, or maybe it is the ability of the Balance Breaker."

"Well, for Issei, Oppai Dragon was extremely important and, above all, it was his pride as well. And now, he just wants to give it all up... This goes beyond abnormal levels... I believe it shows how strong this ability is."

Rossweisse-san spoke.

"Yes, Ise-kun cares for the children of the Underworld. No, he started to care deeply for the children from all factions. He declared himself as [Oppai Dragon] and he took part in countless battles. Wanting to change that...it's just something he wouldn't think about."

"...'Do you like your current self?' That girl asked this question to Issei."

Ingvild-san quietly stated.

...I think that maybe she asked this with the intention of changing Ise-kun's perception from the beginning.

Then, Ravel added in.

"It seems that Grigori will soon report on the Holy Nail. Apparently, in the case of Ise-sama, they were almost able to identify the capabilities of [Alphecca Tyrant]."

I see. So we'd have to wait for Grigori's report.

After that, Rias spoke to organise our current information.

"To sum it up...individuals from the [Alliance of Hell] and the [Hidden Khaos Brigade] invaded the town, discovered Azazel's research and formed a plan to remove Ise's source of power. They also found somebody who had the power to carry out such a plan–"

"The wielder of [Alphecca Tyrant] who's currently in England?"

Saying that was the one who entered the room, Le Fay-san.

She came up to us and then continued with,

"I know the wielder's name. It's Meredith Ordinton, a former mage from the Magician Association called Golden Dawn... She was a colleague of mine."

...It seemed this case involving the [Alliance of Hell] again was really complicated...
