Reincarnated into a Multiverse, but High School DxD

When Ren heard Asia's name, he finally remembered this part of the plot.

Asia had originally been a Church saintess, bearing the healing Sacred Gear, "Twilight Healing."

Because she could heal wounds, the Church regarded her as a gift from heaven. Diodora, a devil who had a fetish for nuns despite being a devil himself, had set his sights on Asia as well. He deliberately disguised himself as an injured, kind-hearted devil, allowing Asia to treat him before having other Church members catch her in the act.

Once it was exposed that a Church saintess could even save devils, Asia's reputation would be utterly ruined.

After that, Diodora would take away those nuns who had been expelled by the Church.

Not every nun had a Sacred Gear, but the process was similar, and it worked remarkably well.

"So the plot is about to begin?"

Ren pondered.

He had previously made a trip to Kuoh Town.

But nothing had been triggered.

What surprised him was that Issei Hyoudou, the original protagonist, had vanished. Although it was strange, Ren had temporarily left because he had failed to trigger any new missions.

Ren figured that after completing this mission, he could take another trip to Kuoh Town.

Maybe he could trigger some of the major plotlines from the original story. The rewards would surely be quite generous.

"Who? Who's outside?!"

Diodora had been smugly reveling in his scheme when he heard a sound by the window and suddenly turned around.

He saw a half-body silhouette reflected on the window.

"A thief?"

Diodora did not sense the aura of a holy official or an Exorcist, so he relaxed slightly. Still, the other party had likely heard his muttering just now. To be safe, it would be better to get rid of them.

Diodora lunged toward the window and reached for the shadow.

He was, after all, a pure-blooded high-class devil, with physical abilities and strength far beyond those of ordinary humans.

But what greeted Diodora was a silver bullet.

The supersonic bullet exploded against Diodora's forehead in a burst of sparks. His body jerked, and he staggered back a few steps without falling.

"As expected, once you run into stronger devils, firearms and weapons like that become hard to use effectively."

Ren felt a little helpless.

He was still quite interested in modern weapons.

Unfortunately, in a mythological world, power without special supernatural reinforcement could hardly inflict effective damage on mid- to high-level beings.

Otherwise, the various mythological factions would not bother with melee weapons. They could just blast each other with guns, artillery, and missiles.

Diodora recovered and felt the sharp pain radiating from his forehead. His previously gentle expression immediately twisted into something monstrous.

The moment his lips tasted his own blood, his rage ignited.

"You dare hurt me! Not even my uncle has ever hit me!"

Purple demonic power rose from Diodora's body. With his speed surging again, he unleashed a powerful blast of energy from his right hand.

The outer wall was instantly blown apart, and the remaining force destroyed several unoccupied buildings nearby.

"You really can't keep your cool, can you? This is the Vatican. Exorcists, maybe even angels, will be coming for you soon."

"You motherfucker...!"

Diodora was nearly driven mad by Ren's calm demeanor.

You had the nerve to say that.

You had no honor at all—pulling a gun the moment you showed up, deceiving him, launching a sneak attack!

If he had not been injured, why would he have chosen to make a move here?!

Still, the guy was right. Diodora had already begun to consider retreating.

He only wanted to bring the saintess home to play with, not provoke those fanatical angels. If a high-ranking angel came, he would be in serious trouble.

Diodora began thinking of running.

But once the thought of retreat took root, his fighting spirit immediately ebbed.

Seizing that opening, Ren abruptly vanished before Diodora's eyes.

[Skill: ClockUp]

[Effect: Upon activation, grants Super Acceleration, greatly speeding up the particles flowing around the user and allowing free movement within the flow of time.]

Excalibur

Chapter 5

Before Diodora had time to react, both his hands and feet were severed.

The Super Acceleration stopped.

The world in Ren's eyes returned to normal, and Ren, who had vanished from everyone else's sight, appeared again.

"AAAAAHHHH! My hands! My feet!"

Reduced to a limbless wreck, Diodora crashed heavily onto the ground. The instant Ren's Super Acceleration ended, excruciating pain swept through his entire body.

The pain turned his face pale, covered him in sweat, and made his eyes bloodshot.

Blood beneath him stained the floor red.

Diodora, who had been pampered since childhood, had never experienced such agony. He lay on the floor howling endlessly.

An ordinary person would have fainted from that level of pain long ago. But as a devil, Diodora possessed immense vitality, which instead became a burden at this moment.

He was not like the pure-blooded devils of the Phenex family, who possessed powerful regenerative abilities and could recover instantly even if their heads were blown apart.

Still, with proper treatment, his limbs could be reattached without affecting his daily life or combat ability.

But this was not the Underworld.

Since he had snuck out without telling anyone, no one in Diodora's family knew where he had gone.

"Stop screaming. You're hurting my ears."

Ren dug at his ear. That bastard's voice was even shriller than a woman's.

Someone would probably be here before long.

"I... I'll kill you!!!"

Diodora temporarily regained his senses and stared at Ren with bloodshot eyes.

If looks could kill, Ren would already have died billions of times over.

"Enough nonsense. Time is short. I ask, you answer. If you answer well, maybe I'll let you go."

Hearing that, the other black-robed girls in the room wanted to speak, but Ren looked like a god of slaughter, scaring them into silence.

Hearing that there was a chance to live, Diodora calmed down slightly. Yet his eyes still held intense hatred and terror.

He was clearly a pure-blooded high-class devil. Why had he been defeated by some insignificant Exorcist?

"Where are the nuns you captured?"

"They're all here."

"What is the name of the saintess you lured tonight? Did she use a Sacred Gear to heal your injuries?"

Diodora's eyes lit up when he heard that.

Right!

He could wait for this guy to release him, then find the saintess and have her use her Sacred Gear to heal his wounds!

"Yes, her name is Asia Argento. But it was my first time seeing a Sacred Gear that could heal devils."

When Diodora had received treatment, he could clearly feel that it was holy light.

But holy light was supposed to be poison to devils. Yet the wounds he had inflicted on himself had indeed been healed by that holy light.

It was incredibly miraculous.

However, Diodora had not thought much about it at the time. After being discovered by other Church members, he had taken advantage of the chaos to leave.

"Can you let me go now? I'm a pure-blooded high-class devil of the Underworld, the current heir to the Astaroth Family. Let me go, and I'll give you many benefits!"

Diodora said through the pain.

"You can, but you still need to answer one final question."

"What question?"

The light of hope rose in Diodora's eyes.

He decided that once he returned to the Underworld, he would immediately use all the power at his disposal to hunt down this damned bastard!

But first, he had to survive!

"It's simple. You just need to prove Goldbach's Conjecture."

"???"

What the hell was Goldbach's Conjecture?

Diodora looked utterly dumbfounded. He had no idea!

"Sorry, since you can't answer, you can only die."

Ren raised his Nichirin Sword.

Though its effect targeted dark creatures, the system-produced version was far more useful than the original. At the very least, it was tougher than ordinary weapons. Otherwise, it really would not have been able to cut through a high-class devil's body.

"Wait! My blood relative is the current Beelzebub Demon King of the Underworld! Ajuka Astaroth is my uncle! You can't kill me! If you kill me, he'll definitely avenge me!"

"Are you done?"

Ren gave him an indifferent glance. Just as he was about to strike, he pulled out his pistol and emptied an entire magazine into Diodora's lower body.

A scream of pain so miserable it seemed capable of piercing the whole world rang out.

After that, Ren pierced Diodora's forehead with a single thrust.

[Mission: "Saintess Disqualified" settlement complete]

[Reward obtained: Church Reputation +10, Holy Sword—Sword in the Lake]

[Holy Sword—Sword in the Lake, also known as EXcalibur. This sword was forged by fairies in Avalon. Its guard is made of gold, its hilt is embedded with gemstones, and its blade cuts through iron like mud. Comes with the Noble Phantasm (Excalibur), which consumes the user's magical power, converts it into light, and releases it.]

"EXcalibur?"

Ren raised an eyebrow.

Wasn't that the Blanket King's exclusive weapon? How had it ended up with him?

It even came with the Noble Phantasm function. It just required magical power to activate, and he had no idea how much it consumed.

If the cost was too high, he could only use it as a trump card.

Still, he could replace the Nichirin Sword with it for everyday use. After all, using a Nichirin Sword against enemies above the high-class devil level was somewhat inadequate.

If Ren's stats had not been high enough, he probably would not even have been able to break through Diodora's defenses.

After checking the system map and confirming that no red dots had appeared for the moment, Ren placed the newly acquired equipment back into his personal space.

He then looked toward the black-robed women in the room.

By then, they had removed their veils and headscarves, revealing faces with all manner of exotic beauty.

Even in a two-dimensional world overflowing with beauties, every one of them would rank above average in appearance.

With the distinctive blonde curls of anime girls, soft Eastern features, and the simplicity and elegance of nuns, it was no wonder a devil like Diodora would develop such peculiar thoughts.

Well, devils having lower moral standards was perfectly normal.

"Thank you for saving us."

One of the nuns clasped her hands together and spoke.

Ren had thought they would next say, "I have no way to repay such a great kindness, so I can only offer myself to you," but reality clearly would not proceed in such a pleasing direction.
