Chapter 128 – Kuroka and Koneko: Reunion of Two Sisters
With a graceful leap like that of a feline, Kuroka dropped down from the tree branch and landed lightly beside Shin Akira.
Her gaze was sharp, yet laced with curiosity. Without warning, she gently licked his cheek—almost like she was marking her territory.
But the moment her tongue made contact, her expression instantly shifted.
"…You've already had a woman, haven't you?"
As a Nekoshou, a rare species of Youkai, Kuroka could sense the flow of energy and lingering pheromones just from a light touch. In an instant, she had read him like a book.
"I'm not like Vali. While I do seek strength, I've never been one to suppress my desires," Akira replied calmly.
"Hmph… your appetite sure doesn't match your elegant appearance," she snorted, flipping back to Vali's side with a slightly colder attitude.
"This form?" Akira smiled faintly. "You've misunderstood. This isn't my real body."
"…What do you mean by that?"
"It's a side effect of the power I've inherited."
"…Don't tell me… so the rumors are true? You really inherited the spirit of Enkidu, that extinct entity from Mesopotamian mythology?"
"You could say that."
In this world, it wasn't unusual for someone to inherit the soul of a legendary hero or a divine aspect.
The Khaos Brigade had plenty of examples—giants wielding Heracles' strength, or a blonde girl carrying the soul of Jeanne d'Arc.
So it wasn't that surprising for someone like Akira to emerge, carrying the living spirit of Enkidu within him.
"…So you came here… for Koneko?"
"That's right. You helped me resolve things with my own little sister. Because of that, I owe you. And now… I'm here to ensure peace remains between you and the Underworld."
Kuroka's voice softened.
In the past, she might have tried to abduct her sister by force. But that time had passed.
Since the reunion orchestrated by Akira, Shirone—better known as Koneko—had forgiven her. The rift between the sisters had finally healed. And that… wasn't something to repay with conflict.
Kuroka had no intention of bringing chaos into the Underworld. She knew well that storming into Gremory territory or Devil Castle would only bring trouble—especially since she was still considered a fugitive by Underworld authorities.
So, she turned to Vali and asked him to summon Akira in secret.
"…So you came just to say thanks?"
"Partly. But more than that… I want to see Shirone. I've put it off long enough."
"You might be disappointed."
"…Why?"
"She's been taken by Rias for special training."
"Training?"
"In the last fight, her control over Senjutsu was still a bit rough. So Rias brought her to refine her skills."
"Hmph. I should be the one training her. No one understands Senjutsu better than me."
"Alright. I'll contact Rias now."
Akira pulled out his Underworld-exclusive phone and sent a short message.
While he tapped away, Bikou just stared at Kuroka, completely speechless. Whenever it came to her little sister, the usually sharp and cunning Kuroka turned into an easily flustered mess.
But he understood. That kind of softness was natural—for an older sister.
"So?" Akira said, shifting his gaze toward Vali, who had been watching him silently. "Do you want to fight again?"
"…Not today. I don't stand a chance right now. Especially now that you've mastered Juggernaut Drive. At the moment… I'm no match for you."
"That doesn't sound like the Vali I know. Backing down so easily?"
"This isn't surrender. Just awareness. But once I break through to Maou-class, I'll be back to challenge you."
"…So you've leveled up again?"
"Mid Ultimate-Class. I broke through a few weeks ago."
"…Impressive. As expected from a true-born Lucifer."
Becoming an Ultimate-Class Devil at seventeen was an achievement matched by only a handful.
In the entire Underworld, only Sairaorg Bael might be able to rival that feat.
But Vali held a decisive advantage—Juggernaut Drive, the pinnacle evolution of Divine Dividing.
Even with his Regulus Nemea Sacred Gear, Sairaorg had only reached Balance Breaker. That alone couldn't match Vali.
Akira's eyes shifted toward Arthur and Kuroka. Both of them possessed power on par with Ultimate-Class Devils.
Unfortunately, that wasn't enough. If only they were stronger, he would've challenged them. After all, he only needed 2% more to complete his inheritance.
A little under thirty minutes later, Rias arrived—with Koneko at her side.
The moment she saw Vali and his group, Rias instinctively grew more alert.
She knew who they were: the Lucifer bloodline, members of the Khaos Brigade—potential enemies of the Underworld.
But at the same time, Koneko's eyes welled up with emotion.
"…Onee-sama…"
"…Shirone…"
The two long-separated sisters finally stood face to face.
"You've grown up so much, Shirone…"
Kuroka smiled gently, her gaze fixed on her little sister, now blossoming into a beautiful young girl.
"And… Onee-sama, you've… also…"
Koneko glanced up and down at her older sister—particularly at her well-developed figure. Her voice trailed off, her cheeks turning red.
Kuroka caught her sister's look and glanced at Akira. Then back at Koneko. She understood immediately. Her sister's stare had been… embarrassingly honest.
"I'm sure you'll grow even more charming than me one day, Shirone. We're sisters, after all. There's no way you'd lose to your big sister, nya~."
"O-Onee-sama…"
Koneko's face turned crimson like a ripe apple.
"…Koneko-chan, you don't have to worry," Akira added with a soft smile. "You're already wonderful just the way you are."
His words weren't empty praise—they were spoken straight from the heart.
He was constantly surrounded by mature, alluring women. Precisely because of that, Koneko's innocence and petite charm were so rare… and precious.
Especially if Akeno and Asia eventually matured into equally curvy bombshells… then a pairing like Kuroka and Koneko—older sister seductive, little sister sweet—would be an irresistible contrast.
"Akira-senpai… Y-You pervert!"
Koneko lowered her head, blushing furiously.
"No way! Shirone's still a kid! It's way too early for that!"
Kuroka immediately pulled her sister behind her and stepped forward like a protective cat ready to pounce.
Her eyes narrowed with sharp wariness as she stared down Akira.
She knew her little sister's Youkai blood could awaken early—and if anything happened before she was ready, it'd be a serious problem.
"…Don't you dare try anything funny with my little sister, got it?"
Her voice was cold—but it was the voice of a sister fiercely guarding something precious.
Akira simply let out a quiet laugh… and didn't deny it.
