The Strongest Eriri in History

Within the depths of the Orcus labyrinth, a blond-haired youth around 17 or 18 years old was engaged in combat with a serpentine monster. However, the youth clearly had the upper hand. Wielding a massive greatsword, he cut through the serpent with splashes of blood staining the stone floor.

Before long, the serpent was vanquished, collapsing lifelessly under the youth's blade. Its body dissolved into light, granting the youth 10 points of "Enhancement Points."

"Another hundred Enhancement Points, not bad." Surveying the ten serpent corpses strewn around him, the youth grinned with satisfaction. He made his way to a protruding rock and sat down, exhaustion apparent after half an hour of relentless combat.

With a flick of his wrist, a water bottle appeared out of thin air. Unscrewing the cap, he took a large gulp before sighing in contentment. "This world was made for me."

Indeed, this blond youth was a transmigrator. In his previous life, he had been a 300-pound otaku whose days were spent consuming endless media, and whose life tragically ended due to sleep apnea caused by his morbid obesity.

When he woke again, he found himself in a body that felt inexplicably light, in a luxurious bedroom clearly not of his old world. He quickly realized he had been reborn, and instead of mourning his past life, he felt sheer ecstasy.

As a lifelong fan of light novels, anime, and games, the idea of transmigration filled him with joy. The room's opulence suggested that his new identity was not ordinary, which only added to his excitement.

Soon after, his transmigrator's "cheat" revealed itself—a system known as the "God-Level Enhancement System."

The system did exactly what its name implied: it could enhance anything—physical strength, abilities, weapons, or equipment. All it required were Enhancement Points, which he could acquire by defeating monsters.

The system wasn't limited to just enhancing the user either; it could strengthen others as well.

Being well-versed in countless fantasy tropes, it didn't take him long to realize he had landed in the world of Arifureta: From Commonplace to World's Strongest.

As for his identity in this world? He was now a member of the Heiligh Kingdom's royal family—a cousin to Liliana S.B. Heiligh, one of the original heroines.

However, this specific cousin did not appear in the original story, suggesting he had lived a low-profile existence before. His life had abruptly ended about a month prior, and it was into this body that the transmigrator had now awakened.

Strangely enough, the boy discovered that the world he was now in had diverged significantly from the original story he knew. The ultimate antagonist, Ehit, had been defeated by an unfamiliar character—a girl named Eri Kashiwagi.

Hearing this name sent him reeling. He recognized it immediately: Eri Kashiwagi was the "blonde loser" from a popular romantic comedy in his previous life. But why was her name being spoken here, in Arifureta's world? How could a mundane high school girl become a divine existence powerful enough to slay a god?

Initially, he dismissed it as a coincidence, assuming this was a case of two unrelated people sharing a name. Still, every time he heard references to the "Kashiwagi Eri Church," unease churned in his gut.

"Seriously, what kind of ero-doujin parody is this supposed to be?"

Despite his misgivings, the transmigrator had no time to waste. Over the course of a month, he had leveraged the God-Level Enhancement System to become one of the strongest individuals in this world.

Now, he felt confident that his destiny was to dominate everything.

In his previous life, he had been a fat loser with no prospects, let alone romantic ones. He had never even held hands with a girl his age.

But now, armed with a handsome face, royal status, and unrivaled power, he had set his sights on building the ultimate harem.

He envisioned a massive crystal palace filled with heroines from every world he planned to conquer.

His immediate targets included Arifureta's heroines: Yue, Shea, Kaori Shirasaki, Tio Klarus, Shizuku Yaegashi, and Aiko Hatayama.

Even Liliana, his supposed cousin, was part of his plans, as was this enigmatic Eri Kashiwagi goddess.

He even considered targeting Myu, justifying it as a "loli-raising" opportunity.

Of course, before making any moves, he needed to eliminate Hajime Nagumo, the protagonist of this world. Though Hajime had already grown strong by this point in the timeline, the transmigrator believed he could now overwhelm him.

For the past month, he had been relentlessly grinding monsters in the Orcus Labyrinth, waiting until he was certain of his superiority before revealing himself.

At last, after slaying ten serpentine monsters, he finally accumulated enough Enhancement Points for another boost.

Spending all his points, he powered himself up to a new level.

"Haha, incredible! A single full-power attack could wipe out an entire city. Aside from gods, I must be the strongest being in this world now!"

Convinced of his invincibility, the blond youth began ascending the labyrinth, eager to finally set his plans into motion.

Meanwhile, in a distant part of the Arifureta world, Eriri was alerted by Little Skirt's voice:

"Onee-sama, should I issue a group task? A hostile transmigrator has appeared."

"Yes, issue the task," Eriri replied without hesitation. Her expression grew sharper as she pondered the situation. "It's surprising—after Arifureta, there's already another transmigrator here? Seems like this world is a magnet for anomalies."

Moments later, the system's notification echoed in the minds of every group member:

[Ding! A group task has been issued in the world of Arifureta: From Commonplace to World's Strongest.]

[Task Details]

• Objective: Eliminate the hostile transmigrator.

• Target Identity: A member of the Heiligh Kingdom's royal family.

• Target Strength: Extraordinary Level/Stage 2 Rank 9.

• Completion Reward: 10,000 points.

• Participant Limit: Three members (excluding the group leader and the mission initiator).

Eager to respond, group members immediately began discussing their plans to take on this new challenge. Eriri, on the other hand, remained calm, confident in her group's abilities to crush the new threat before it could upset the balance of this world.

[Chika Fujiwara (Level 5, Stage 2): It's here! The group task is finally here again!]

[Ruri Gokou (Level 5, Stage 1): Yay!]

[Elaina (Level 5, Stage 3): Time to earn some more points, I'm so happy.]

[Milim (Level 6, Stage 9 ~ Level 7, Stage 1): A group task? Sounds super fun! I'm in, I'm in!]

[Fubuki (Level 5, Stage 1): Why doesn't this one have any bonus rewards? Confused.jpg]

[Fumino Furuhashi (Level 2, Stage 1): This task's reward is so small! It's not even as much as what I got from the red envelope the other day.]

Fumino Furuhashi's understanding of the chat group's point system had already been skewed. With no rare treasures to exchange for points, she couldn't grasp their true value.

Red envelopes casually sent by Eriri contained tens of thousands of points, and the veteran members frequently handed out such gifts or flaunted their results from one-point-per-draw lotteries.

At 10,000 points per draw, they pulled gacha in ten-shot batches like it was a game, giving Fumino Furuhashi the mistaken impression that earning points was easy.

In any other group, this assumption would have been met with harsh reality.

But in this group, it happened to be true.

With someone like Eriri—a peerless powerhouse who didn't need points and could achieve almost anything through sheer strength—earning points really was effortless for everyone else.

[Chika Fujiwara (Level 5, Stage 2): You don't get it, do you? Who cares about the task's reward? The real prize is the transmigrator's system—that's the actual source of points!]

[Ruri Gokou (Level 5, Stage 1): Exactly! Even the most garbage Low-Level system is worth 100,000 points. Mid-level systems? 10 million. High-level systems are on another level entirely.]

[Fumino Furuhashi (Level 2, Stage 1): But what if this transmigrator doesn't have a system?]

[Ruri Gokou (Level 5, Stage 1): Transmigrator plus system is practically standard issue, isn't it?!]

[Eriri (Level 8, Stage 7): Whether it's standard or not, I can confirm that this task's target does have a system.]

[Nakiri Erina (Level 3, Stage 8): That's great news—I'm fresh out of points.]

[Arche (Level 5, Stage 4): What kind of system is it? Anticipation.jpg.]

[Yuuki Asuna (Level 5, Stage 2): Let's hope it's at least Mid-Level.]

[Chika Fujiwara (Level 5, Stage 2): Fingers crossed for a high-level one. Aside from that Villains Chat Group, I haven't seen a High-Level system yet.]

[Arifureta (Level 5, Stage 5 / Group Leader): We've only encountered a few systems total…]

[Kanae Kocho (Level 5, Stage 3): Eriri, Yue-chan, does this mean a world must have a member present for the group to detect the presence of transmigrators or reincarnators?]

[Eriri (Level 8, Stage 7): Exactly. Every group member carries a sub-system of the chat group, which is what scans their respective worlds. Once a member leaves a world, the monitoring sub-system leaves too.]

[Kanae Kocho (Level 5, Stage 3): That makes sense. Looks like I'll need to return to my world regularly to check for any disturbances. It'd be bad if some transmigrator or reincarnator caused chaos while I was away—it's still my birthplace, after all.]

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): Ah, it's been two months since I last went back. I wonder if there's been any trouble…]

[Gabriel (Level 5, Stage 1): …]

[Chika Fujiwara (Level 5, Stage 2): Don't worry so much! It's not like problems pop up that easily.]

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): No, I can't relax. I'll go back right now to check things out. My father's strong, but he's only Level 7—there are plenty of people in the multiverse stronger than him.]

Though Lala had initially fled to the Saekano world to avoid marriage proposals and had no intention of returning, she still cared deeply about her home world.

After typing her message, Lala immediately spent 1,000 points to purchase a Cross-Boundary Talisman, teleporting back to the To Love-Ru world and returning to Deviluke.

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): I'm back on Deviluke! Little Skirt, could you check for anomalies here?]

[Ding! No anomalies detected.]

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): Phew, that's a relief. Heading back to the Saekano world now.]

The entire process—from Lala teleporting back to her world to returning—took less than 30 seconds.

The other group members were stunned by her swift and efficient approach.

[Chika Fujiwara (Level 5, Stage 2): Uh, wow…]

[Kanae Kocho (Level 5, Stage 3): Lala, seriously? You didn't even stop to see your parents?]

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): Eh-heh, there's no need. If I did, my dad would just try to set me up with more suitors. No thanks!]

[Ruri Gokou (Level 5, Stage 1): Isn't there a better way to handle that? Getting ambushed while world-hopping would be disastrous.]

[Eriri (Level 8, Stage 7): That's easy to solve. Little Skirt, just keep monitoring all group members' worlds, even when they're away.]

[Ding! Understood, Onee-sama! Little Skirt will begin multi-world monitoring now.]

[Lala (Level 6, Stage 9 ~ Level 7, Stage 1): That's fantastic—no need for constant check-ins anymore!]

[Elaina (Level 5, Stage 3): This is perfect. Once I finish traveling through this world, I plan to visit others. This way, I won't have to worry about leaving my home world unattended.]

Eriri's decision brought immense relief to the group members. None of them could guarantee they'd remain in their own universes forever.

With Little Skirt's expanded monitoring, they could now freely travel wherever they wished without fear of leaving their worlds vulnerable.
