As time went on, that initial admiration deepened, eventually becoming what she mistook for love.
In truth, the feelings between them had only truly begun to blossom when they met in person—when they supported each other and grew closer through shared struggles.
However, since Kaori Miyazono had long admired Kousei Arima, she never noticed that this feeling had subtly changed. She simply assumed that she had always been in love with him.
"Eriri-nee, what should I do now? I... I'm so confused."
Kaori lifted her gaze toward Eriri, her face filled with uncertainty and inner conflict.
In the original story, she knew her life was short, so she wanted to use her final days to help Kousei Arima step out of his trauma and return to the piano.
But now, Kousei Arima had already overcome his pain—and even given up on music altogether.
That realization left Kaori utterly lost.
She had fallen in love with him because of his music, yet now he had abandoned the piano so easily. It was as if her years of devotion had turned into a joke.
"That's something only you can decide," Eriri said gently. "No matter what choice you make, I'll support you—as long as you don't let yourself down."
Hearing that, Kaori lowered her head again, falling silent.
It wasn't until some time passed that she finally spoke once more.
"Then... I think I'll give up. I don't have much time left anyway. The Kousei Arima who gave up on piano isn't the one I fell for anymore. Besides... I don't want to ruin what he has with his childhood friend."
Kaori chose to face reality. The once radiant image of Kousei Arima that lived in her heart dimmed into a faint shadow.
Wiping away the tears that had unknowingly slipped down her cheeks, Kaori forced a faint smile and looked at Eriri.
"By the way, I still don't know why you came to find me, Eriri-nee."
When Eriri had first approached her, she'd only introduced herself and briefly mentioned that she had come specifically for Kaori's sake, but hadn't elaborated further.
At first, Kaori had been struck by Eriri's beauty. Her bright, energetic personality made it easy for the two to get along quickly, and before long, Kaori was calling her "Eriri-nee" affectionately.
Later, Eriri had added Kaori to the Multiverse Chat Group and explained what the group was.
At first, Kaori had been full of curiosity about this mysterious chat, but when she saw the conversation between Eriri and Kousei Arima... the smile that had been on her face quietly disappeared.
Since then, she had remained trapped in confusion and sorrow.
"It's nothing much," Eriri said softly, reaching out to stroke Kaori's hair with a gentle smile. "I just thought you were a poor little thing... so I decided to heal your body and let you live happily."
"R-really...?"
Kaori's eyes widened in disbelief. The sudden good news snapped her out of her gloomy thoughts.
Ever since she had learned of her terminal illness, what pained her most wasn't the thought of dying—but the sorrow her parents would endure because of her death.
So if there was even a chance she could be cured, she would grasp it with everything she had.
As for whether Eriri truly had that power—Kaori never doubted it for a second.
After all, she had witnessed Eriri appear out of thin air and invite her into that miraculous chat group.
Everything about her presence radiated power—and Kaori knew Eriri had no reason to deceive her.
"Of course I can," Eriri said with a confident nod.
Without another word, she pressed her palm lightly to Kaori's forehead, channeling a thread of cosmic energy into the girl's body.
In an instant, under the nourishment of that boundless energy, all traces of illness within Kaori vanished completely. Even her mild nearsightedness disappeared.
"There we go," Eriri said, withdrawing her hand and the energy that had been flowing through Kaori. "Your body's back to normal. You'll be able to leave the hospital soon."
Feeling the surge of strength returning to her limbs, Kaori's face lit up with uncontrollable joy.
Moments later, she clambered up from the hospital bed with both hands and feet.
"I'm really healed!"
Standing atop the bed, Kaori stretched out her arms and legs, relishing the powerful, energetic sensation coursing through her body.
After a while of joyful movement, she finally calmed down.
Then, without warning, she sat back on the bed and burst into tears—tears that ignored Eriri's gentle gaze from the side.
But unlike the sorrowful tears she had shed before, these were tears of joy.
They marked the beginning of Kaori Miyazono's rebirth.
The shadow of Kousei Arima's fading figure in her heart vanished completely, replaced by Eriri's ethereal beauty.
...
"Eriri-nee, thank you so much!"
Kaori bowed deeply before Eriri, her expression filled with heartfelt gratitude.
"No need for thanks. Since your body's already healed, it's about time for me to leave."
Eriri smiled softly as she helped Kaori back up, then playfully pinched her cheeks.
"Huh? Leave?"
Kaori, whose cheeks were still warm from Eriri's touch, froze upon hearing those words.
"Eriri-nee, can you please not go yet...?" she pleaded, her small face showing an expression of deep reluctance.
"And stay for what? Do you plan to make me stay for dinner?" Eriri teased with a mischievous smile, ruffling Kaori's golden hair.
"Of course! You cured me, after all! Once my parents find out, they'll definitely want to thank you properly!"
Seeing Kaori's serious and earnest face, Eriri couldn't help but laugh softly and ruffle her hair again.
"Alright, alright, I was only joking. There's no need for any thanks. Who knows if we'll even get the chance to meet again~"
Kaori's expression immediately changed at those words, her heart tightening with unease.
"Eriri-nee, why would you say that? Does that mean... you don't plan on ever visiting me again?"
Kaori looked up at her with tearful eyes, terrified of hearing an answer she couldn't bear.
"Perhaps not," Eriri said with a faint smile.
"No!"
Kaori shook her head violently, refusing to accept that.
"I don't want to never see Eriri-nee again!"
She reached out and grabbed tightly onto Eriri's clothes, afraid that she might vanish from the room just like when she appeared.
Her little face was filled with determination, and the tears she had just wiped away once again welled up in her eyes.
"Are you really that unwilling to let me go? We've only known each other for a short time, you know~"
Kaori didn't reply. She only nodded firmly, her stubborn gaze locked onto Eriri's.
Seeing her like that, Eriri couldn't bring herself to leave.
"Alright, alright. Since you're so insistent, I'll stay a little longer," she said with a faint chuckle.
Hearing that, Kaori finally let out a relieved sigh, though her hands still clutched Eriri's clothes tightly.
...
After deciding to remain a while longer in the Your Lie in April world, Eriri took Kaori out of the hospital.
To prevent any trouble from the hospital later, she simply erased all memories of Kaori's illness from the minds of the doctors and staff.
Now, aside from her parents and Kousei Arima—who was still part of the Multiverse Chat Group—no one knew that Kaori had ever suffered from a terminal disease.
As for Kousei Arima, who had been declared "out of the game" by Eriri, once he left the chat group, all memories related to Your Lie in April would be erased from his mind as well.
Meanwhile, within the Multiverse Chat Group, even though Eriri hadn't reappeared, the atmosphere remained tense.
After all, Arifureta and the others had no intention of letting Adam off the hook for verbally humiliating Eriri.
Even knowing that his death was inevitable, they were determined to make sure his final moments would be anything but peaceful.
Thus, during this period, Arifureta and several others continued to relentlessly mock, ridicule, and verbally attack Adam in the chat.
They had joined the group as mere bystanders, yet somehow became the main driving force behind his downfall.
After enduring relentless mockery and verbal attacks for so long, Adam finally gave up trying to pretend anymore.
[Adam: Keep barking, you wretched women. Once the system of this chat group recovers, I'll personally kick every single one of you out!]
[Kaguya Shinomiya: So that's why you've been hiding like a turtle all this time—you lost the permission to kick people out! And here I thought you were being magnanimous. How laughable.]
[Arifureta: Exactly. Even the chat system can't stand you anymore, disgusting group leader. Why don't you just hand over your position before the group itself decides to kill you?]
[Adam: Hmph, keep talking. None of you will be laughing for long.]
[Adam: You should all be grateful that the Cross-Realm Teleportation is restricted. Otherwise, I'd already be in your worlds, making you wish for death!]
[Million-Word Author: Oh, stop talking tough. Do you believe I can't cross over and smash your skull right now?]
[Adam: Oh, I'm so scared~ Go ahead, try it! You're nothing but a Level 1, Stage 2 mortal trash acting like a big shot.]
[Kashiwagi Eri: Very well. Since you're so eager to die, I'll gladly grant your wish.]
By this point, Eriri had lost all interest in continuing the game. She decided it was time to put an end to the Multiverse Chat & Friendship Group itself.
After sending that message, Eriri quietly muted Adam from seeing any further chat messages.
However, she didn't let him realize it. To Adam, it simply appeared as though everyone had gone silent.
Then, Eriri activated a new feature within the chat group—a live broadcast, despite the fact that such a function had never existed before.
[Chika Fujiwara: Oooh! Looks like something exciting's about to happen!]
[Muscle God: Live broadcast? Since when did we have that function?]
[Phone Hero: I don't think we ever did.]
[Uchiha Dance King: Live... broadcast? What is that supposed to mean?]
[Mirror Flower Moon Shadow: Interesting.]
[2.5 Satoru: Opening a live stream now? I want to see what you're planning to show us.]
Because of the broadcast's sudden start, even members who hadn't spoken for a long time due to Arifureta's earlier dominance reappeared, all curious about what Eriri was about to reveal.
Whether it was those familiar with livestreams—like Satoru—or those who had no idea what one was—like Madara—they all entered the stream immediately.
However, what appeared on the screen wasn't Eriri as they expected—but rather, a scene that made their eyes sting.
The broadcast displayed a luxurious living room. On the sofa sat a shirtless black-haired young man, arrogantly lounging with two scantily dressed girls in his arms.
The boy's face was plastered with a smug, disdainful grin, his hands shamelessly roaming across the girls' bodies.
Seeing the indecent display, the female members in the stream instantly frowned in disgust.
[Elf Sister: Disgusting!]
[Female Shogi Player: Shameful!]
[Part-Time Warrior: Gross!]
[Kousei Arima: That's... Adam-bro?]
Blushing furiously, Kousei immediately recognized the man in the video.
And not just him—the other veteran members recognized Adam too, as he had once shared pictures and videos of himself in the chat.
Meanwhile, Adam, oblivious to the fact that he was being livestreamed, continued his debauchery—groping the girls beside him to vent his frustration.
[2.5 Satoru: Hah, so this is what he's been up to.]
[Muscle God: Looks like this is Adam's true nature.]
[Phone Hero: Wait... what's that?]
Following Touya Mochizuki's message, everyone's attention shifted away from the obscene scene to the background.
There, just a few meters behind Adam, a strange and intricate spatial rift had formed in the air.
Naturally, this sudden anomaly caught Adam's attention. His expression grew tense as he sat up straight, withdrawing his hands from the two girls' clothes.
The next moment, a small figure stepped out of the glowing rift—a petite girl with long golden hair, dressed in a pink Gothic Lolita outfit, her appearance both adorable and elegant.
The girl who emerged was none other than Elf Yamada, who had just crossed the universe from the Oreimo world.
And the one who had opened that dimensional portal for her—was none other than Eriri, watching from the Your Lie in April world.
