The Enhanced Doomsday Gene!

Fuyuki City.

On the quiet streets at night, at this moment, whoosh—

Crack—

A black hole appeared in the fabric of reality, and then a figure was thrown out of it.

This figure was Rizel.

"Damn, my head hurts. This world travel really feels like I'm being tossed around in a tunnel, it's like being flushed down a toilet," Rizel muttered in frustration.

Rizel looked around. It seemed he had been thrown into a narrow alley, and he noticed there was no one around.

Far away, within an ancient palace, two young girls sat at a round table, watching the scene of Rizel just entering this world.

These two girls were extremely famous figures within the Type-Moon universe: Alaya and Gaia, the two great forces that maintain balance.

Alaya, as the force of restraint, embodied the highest human will, preventing the extinction of humanity.

Meanwhile, Gaia's will was tied to the Earth itself— as long as Earth existed, everything could be negotiated. Therefore, Alaya's role was considered more active compared to Gaia's.

"Gaia, it looks like a person from another world has arrived," Alaya said, taking a sip of tea with a hint of interest.

"Oh, so you want to destroy him?" Gaia replied emotionlessly.

"Hmph, let's leave that for now. We'll see how things play out. We'll observe him here and gather information. Once we know more, we can determine if he poses a threat," Alaya said with a mischievous tone.

"Alaya, you're peeping too much," Gaia responded without changing her expression.

"Hey, hey, how can you say that? I'm doing this for the good of this world. What if someone comes to destroy the world? What will we do then?" Alaya said, flustered. "We're close friends, how could you say that about me?"

At this moment, Rizel was communicating with the system.

[ Ding! Master has successfully arrived in the Type-Moon world. You have received a mysterious new player gift package.

Would you like to open it? ]

A mechanical, insect-like voice echoed inside Rizel's mind.

Rizel, filled with excitement, said, "As expected, there's still a new player gift package!" This familiar routine was exactly what he expected, and indeed, there was a new player gift.

"Open it," Rizel muttered.

[ Ding! Opening the mysterious new player gift package….

Congratulations, master!

You've obtained "Perfectly Enhanced Ancient Doomsday Gene." ]

Tzzzz—

Rizel stared blankly for a moment, unable to believe what he was hearing.

What did he just hear? Doomsday? Could it be the Doomsday he was imagining?

[ Ding! Yes, master, it is exactly the one you're thinking of. Through system improvement and enhancement, this Doomsday gene is far stronger than the original.

It is truly immortal, indestructible, and evolves infinitely. No matter what it is—whether it's the sun or any energy source—it can promote evolution. ]

Rizel's eyes burned with excitement. What was this? This was truly Doomsday!

Not the weak version from the movies. This was the ancient Doomsday from the manga, one that wasn't afraid of Kryptonite or any attack, with any further attacks losing their effectiveness. It was stronger than even a saint fighter.

An infinitely evolving monster. Even DC would have a hard time imagining the kind of monster he would turn into.

Based on the manga's portrayal, as long as the conceptual ability wasn't altered, it couldn't be killed. Perhaps only the original boundary could restrain it.

And now, with this enhancement through the system, its abilities were far beyond the original. If it continued to evolve, it seemed even the supreme gods of DC would be unable to erase it.

This was it. This was his time to rise.

With this power, tearing Servants apart with his hands and kicking 'Beasts' would be as easy as flipping a coin.

After a period of evolution, playing around with Akai Tsuki wouldn't be impossible either.

At the moment Rizel was overwhelmed with excitement, he didn't realize that this event had caught the attention of a figure above.

Ryougi Shiki, born in the Ryougi family, one of the four main families of the demon world. She possessed the ability to see the death line and cut it (Mystic Eyes of Death Perception). She also had multiple personalities.

One personality was her true self, representing the negative aspect, and was the primary personality of Ryougi Shiki.

The other was a secondary personality, representing the positive aspect, and was called Ryougi SHIKI.

The last one is the origin, also known as the Origin or Void Shiki.

She walked toward the alley rooftop where Rizel had arrived through the portal.

Following the instructions of the Origin Shiki, she came to this place, curious about what would happen.

As a result, she witnessed Rizel emerging from the black hole.

Ryougi Shiki observed Rizel's appearance with a mix of shock and confusion, remaining silent for a moment.

Is this person mentally ill? One moment he's startled, the next he's calm. Could his mind be broken?

At that moment, Ryougi Shiki's personality switched to Origin Shiki. Due to the connection with the Root, at this moment, Origin Shiki looked unusually beautiful.

There was a family in the Clock Tower, and their method of pursuit towards the Root was beauty itself.

Every era would cultivate a Koganehime and Shiroganehime, helping them become ever more beautiful, all the way to the origin.

Therefore, as long as Origin Shiki wished, she could radiate an absolutely superior beauty.

At this moment, Origin Shiki indeed did so, exuding this unparalleled beauty.

Origin Shiki, uninterested in anything else, usually relinquished control of the body to Ryougi Shiki.

However, this time, she was captivated, observing Rizel's figure and feeling a soul-stirring attraction.

She was intrigued, wondering what could cause such a reaction in her.

She meticulously examined Rizel and couldn't help but acknowledge that he was indeed handsome. The charm emanating from him exceeded even the beauty of her origin.

On the other hand, Rizel, unaware that he was being watched from above, was preparing to merge his Doomsday gene.

"System, merge it for me," Rizel muttered.

[ Ding! Starting the fusion…. ]

Boom—

A powerful aura radiated from Rizel's body, and the surrounding floor was torn apart.

Above him, Origin Shiki furrowed her brow. "I can't see through him; this aura is incredibly strong."

At this moment, Rizel felt extremely uncomfortable. His blood was boiling, as if it were about to erupt, and his cells were wildly dying and regenerating. The pain relentlessly struck Rizel's nerves, and his skin began to ooze with blood.

"A a a a a a a!" Rizel's face twisted in agony as he screamed.

Origin Shiki, observing Rizel's life force rapidly dropping and then rising, felt confused.

Several minutes later, Rizel's blood no longer leaked out, and his cells felt extremely comfortable, as if years of pent-up energy had been released. He felt an overwhelming surge of strength within him.

At this point, his clothes had already fallen apart, revealing his body, which had been enhanced by the gene modification. His muscles were powerful yet still maintained an aesthetic form.

[ Ding! Fusion successful! ]

Rizel could feel an endless power coursing through him, transforming from a mere weakling into a monstrous being of limitless strength.

Finally, he had the power to participate in the Holy Grail War. Now, he needed to confirm the time and check how much time was left before the Holy Grail War began.

He must free Irisviel and Illya from the Holy Grail, which held their fates inside.

As for Emiya Kiritsugu, he could go find Kotomine Kirei and duel him with swords.

"System, check the status!"
