Sixteen years ago, he had suddenly transmigrated into this world.
His originally adult body had reverted into that of an infant, and he became the child of a minor branch family belonging to the Himejima Clan, one of the Five Great Noble Houses.
He was given the name Himejima Shinki.
Coincidentally, his name in his previous life had also been Shinki.
But a name wasn’t important.
Although his body had become that of a baby, his consciousness and memories remained those of an adult.
He remembered everything from his previous life clearly.
Then, when he was five years old, his parents in this world died together during an exorcism mission, leaving behind only him and a modest inheritance.
Fortunately, his parents were distantly related to the Himejima main family, so as an orphan, Shinki was brought into the clan’s main household.
At the same time, once he was finally old enough to access various records and documents, he realized something shocking.
This was the world of High School DxD.
He had been reborn as a member of the Himejima Clan, one of the Five Great Noble Houses.
The very same family that Himejima Akeno, one of Rias’s peerage members in the original story, had come from.
However, after learning all this, Shinki didn’t feel excited.
Instead, he developed a massive headache.
Sure, the protagonist Hyoudou Issei ended up surrounded by beautiful girls after becoming Rias’s servant, but this world was incredibly dangerous.
Yokai, evil spirits, demons, gods, fallen angels, angels—every kind of mythical being actually existed here.
Every day, people vanished without explanation.
For all anyone knew, they had been dragged away by demons or monsters and turned into someone’s lunch.
Because of that, Shinki never relied on his supposed advantage as someone who knew the plot.
He certainly wasn’t reckless enough to wander around outside.
Instead, he obediently stayed within the Himejima Clan and kept a low profile.
The outside world was dangerous, but the headquarters of one of the Five Great Noble Houses was relatively safe.
He had no interest in walking out the door and immediately running into a monster.
This world was simply too terrifying.
Even the weakest Lower-Class Fallen Angel could flatten a small mountain.
Middle-Class Fallen Angels, the backbone of their forces, could easily destroy an entire mountain village.
A High-Class Devil could wipe out a small town without difficulty.
As for an Ultimate-Class Devil, destroying a major city was as easy as eating and drinking.
And a Demon King?
A Demon King could probably erase the island nation beneath his feet in less than twenty minutes.
Way too dangerous.
Absolutely not something he wanted to mess with.
And above the Demon Kings were even more absurd existences—Transcenders, the Two Heavenly Dragons, the Infinite Dragon God Ophis, and Great Red.
Then above even Great Red were Outer Gods from other dimensions capable of casually killing beings on the level of Dragon Gods.
Even worse, several decades later, the Mechanical Evil Gods from another world would invade Earth and bring about the destruction of the entire planet.
Damn it!
Back when he watched the anime, he had been too busy looking at boobs.
Who would’ve thought the world itself was this terrifying?
Fortunately, the place he had transmigrated into wasn’t bad.
At the very least, he wasn’t going to get randomly kidnapped and eaten by a stray demon during childhood.
Then, when he turned twelve, the standard transmigrator cheat finally awakened.
Actually, it had activated the moment he arrived in this world.
The problem was that it had remained in a loading state the entire time.
And that loading process had lasted twelve years.
Twelve years!
A whole twelve years!
Did anyone know how he had survived those twelve years?
Shinki had spent all that time lying low within the main family, studying the Shinto Arts used for exorcism alongside others his age.
Unfortunately, perhaps due to some kind of incompatibility between soul and body, he never displayed much talent.
Even after training for over a decade, he remained mediocre at best.
As a result, he had no choice but to focus on physical conditioning and hand-to-hand combat instead.
The whole thing felt suspiciously similar to those stories where a magical ring containing an old grandpa secretly absorbs energy for years.
Regardless, his cheat had finally awakened on his twelfth birthday.
The system possessed no real intelligence and contained only a single function.
Its name was…
“Holy Spirit Summoning.” This ability allowed the host to consume summoning attempts and, with or without offerings, summon any living being or item from both physical and fictional worlds.
The downside was its extreme randomness.
It was basically like a gacha system from an online game.
If your luck was good, you could obtain incredible treasures.
If you were cursed with terrible luck, no amount of money would save you.
Still, his cheat didn’t seem nearly as predatory as game companies.
The reason was simple.
It appeared to have both a pity system and exceptionally high randomness.
The chances of drawing junk weren’t low, but the chances of obtaining something amazing weren’t low either.
After all, during his very first summon, Shinki had thrown in several talismans issued by the main family as offerings.
After consuming one summoning attempt, he received the first special item of his life.
To be more precise, it was almost like a Sacred Gear.
But it definitely wasn’t a Sacred Gear that had ever existed in the world of High School DxD.
What Shinki obtained was a card.
—The Egg of The Winged Dragon of Ra.
It originated from the world of Yu-Gi-Oh!, belonging to the strongest of the Three Egyptian God Cards that served the Pharaoh.
When all three Egyptian Gods gathered together, they could even summon the Creator God of Light.
If fully manifested, such a being would possess power on at least a universal scale.
And even the Three Egyptian Gods themselves would never be weaker than the Infinite Dragon God Ophis.
In fact, as sacrifices capable of summoning the Creator God of Light, the divine status of The Ra was undoubtedly countless times higher than that of the gods in the High School DxD universe.
But…
What did any of that have to do with an egg?
No matter how powerful The Ra was, the item Shinki had obtained was merely The Ra’s Egg.
