Chapter 317 The Nonaka Sisters
Edited by: Kanaa-senpai
Aki’s change from “Weapon Apprentice” to “Weapon Master” was entirely thanks to Kiba Yuhime.
The so-called Holy Swords and Magic Swords often took on strange forms. Not only were their shapes bizarre, but they each possessed unique [abilities]—some didn’t even qualify as swords at all. The Holy Sword technique she had mastered, [Sword Birth], was essentially the ability to wield all kinds of unusual weapons. Naturally, this [Talent] combined with [Weapon Apprentice], raising it into [Weapon Master] and quickly boosting Aki’s skill with various weapons by a large amount.
”Hmm, still missing a [Barrier]-type [Talent].” Aki rubbed his chin. “Lady Grayfia seems quite skilled with barriers. During the [Three Factions Talk], she was responsible for all related matters, and she was even the one who finally broke the sealed space…”
After thinking it over for a while, he ultimately dropped the thought.
He couldn’t read Sirzechs—not his intentions, nor his true strength. It wasn’t worth the risk for an uncertain [Talent], and actively stealing someone else’s subordinate wasn’t Aki’s style.
But if the silver-haired beauty were to take the initiative herself, then…
Aki had intended to provide first treatment for Xue and Isabella during the last two days of summer break; after all, it had been put off for quite some time. However, Ravel requested they wait until she reached [Breaching], so the three of them could [Dual Cultivation] with Aki together. The blonde-drilled [Devils] heiress had been quite matter-of-fact about it: “Within a [Peerage], it’s perfectly normal for maids to serve the male [Master] alongside a female [Master], especially since Xue and Isabella are already destined for [Dual Cultivation] with Aki. Sometimes, if the female [Master] is feeling unwell, it’s even expected for the maids to take charge of the male [Master]’s physical needs.”1
It was somewhat like the personal maids of noblewomen in ancient Chinese history.
Since Xue and Isabella naturally had no complaints, the matter was temporarily set aside.
In early September, Kuoh Academy welcomed its second semester. Although summer break had ended, the weather had yet to turn cool, and the girls’ JK uniforms stayed light and breezy.
In Class 2-A, Aki sat at his desk, chatting idly with Basara Toujou.
Despite it being the first day of school, he was spared the trouble of dealing with the girls in the class, as Yuuto had already changed into Kiba Yuhime. Aside from the members of the Occult Research Club, the Naruse sisters living in the mansion had also known about this for some time. Basara Toujou had naturally heard of it from his cousin, so he didn’t pay much attention to the situation.
”Hey, Aki. Can yer body handle all this?” Basara Toujou leaned over, resting an arm on Aki’s desk, and teased, “Mio and Maria told me ya haven’t had a single day off.”
Aki glanced at him sideways. “What? Jealous?”
”A little.” Basara Toujou admitted honestly, “But I don’t intend to get a girlfriend until I rescue my mother.”
Since learning his family line and knowing that enemies were watching from the shadows, Basara Toujou had stopped running. He had been training actively during this period, striving to overcome his inner conflicts. As a [Mixed-blood] child of destiny among the four clans, his strength had risen rapidly once he got serious. At this point, his combat skill alone was at the [SS-Rank], and with the [ability] of [Banishing Shift], he could even hold his ground against a weaker [Demon King-class] opponent like Kokabiel.
However, this level of power was still a bit short for taking down Zolgear, let alone rescuing his mother from the [God-faction], Aeva.
Riiiing…
The class bell rang. The girls who had been surrounding Kiba Yuhime returned to their seats. After a brief period of noise, the classroom fell quiet.
But this quiet only lasted a moment. When Kalawarner walked into the classroom with two fresh, lively schoolgirls in tow, a stir swept through the room. Aki and Basara Toujou reacted the most strongly, though both managed to control themselves well.
On the podium, the tall, short-haired girl with sky-blue hair bowed slightly with a rather cold expression. “I am Nonaka Yuki. Please treat me well from here on out.”

”I am Nonaka Kurumi. Please take care of me.”
The other girl, slightly smaller with a light [Purple Ponytail], was more spirited, though her gaze would sweep toward Aki’s direction on purpose while she spoke.
”Hey, hey, judging by your names, are you sisters?” A bubbly girl in the class couldn’t hold back her curiosity and asked.
”Yes, Kurumi is my younger sister.”
”Eh? If that’s the case, why are your hair colors different, and why are you in the same grade?”
Nonaka Yuki’s eyes stayed cold, and she tossed out a few excuses to brush it off. They hadn’t come here to attend school, nor were they there to make friends; they were there to complete the village’s mission.
Kalawarner didn’t rush the lesson, giving everyone ten minutes to get to know the new [classmates] before pointing to the empty space to Aki’s right. “You two sit there for now. Uesugi and Toujou, you go move two sets of desks and chairs from the empty classroom.”
”Yes.” Aki and Basara replied together.
Aki stood up, suddenly noticing the serious and heavy expression on Basara Toujou’s face.
Hm? Is that really the look one gives upon seeing a childhood friend?
Puzzled, he turned his focus back to the Nonaka sisters and realized something seemed off. Basara Toujou was sitting in front of Aki; he had previously assumed the two sisters’ gazes were directed at him. Now, as he moved, he realized they seemed to have been watching him the entire time.
At the same time, Basara Toujou also noticed this. While he felt a sense of relief, he also grew curious about why Aki had caught the attention of the [Hero Clan].
Once the desks and chairs were set up, Aki returned to his seat amidst the Nonaka sisters’ contrasting expressions—one cold, the other lively. As he sat down, his gaze crossed with Basara Toujou’s, and the two nodded at each other in silent understanding. It didn’t matter if they didn’t know the Nonaka sisters’ true motives yet; they could share information later. Aki was curious why the sisters’ relationship with Basara Toujou differed from his memories, while Basara Toujou was curious why the [Hero Clan] had suddenly appeared.
Breezing in the wind from the window, Aki spent a pleasant morning. During that time, he and Basara Toujou kept watching the Nonaka sisters, while the pair of beautiful and cute [Sister Flowers] from the [Hero Clan] also sought every chance to observe Aki while dealing with their eager [classmates].
”Basara, let’s go. It’s the first day of school, let’s grab lunch together.”
”Mm. I didn’t bring a bento today, so I was going to the cafeteria. How about you?”
”I didn’t bring one either. Let’s go.”
Lunch break began, and Aki and Basara Toujou left the classroom together. Seeing this, the girls who had wanted to bother Aki during the break could only give up. The Nonaka sisters exchanged a glance and were just about to follow when Kiba Yuhime and Asia’s group blocked their path.
”Nonaka-classmate, our [Buchou] has requested your presence.”
”Rias Gremory?” Nonaka Yuki’s voice remained cold and clear. [Spiritual Power] flowed faintly within her body, and the pretty, sky-blue bangs on her forehead stirred without a breeze. “Apologies, we have more important matters at the moment.”
”Don’t misunderstand.” Kiba Yuhime smiled slightly, her long, platinum-blonde hair waving as well. An aura no weaker than the sisters’ [Mana] began to show.
The crash of their auras kicked up a sudden gust of wind in the classroom. There were no ordinary people in Class 2-A; the girls remaining in the room realized something was wrong and quickly stepped back. Nonaka Kurumi had wanted to help, but found a familiar figure standing before her—it was the [White-haired loli] who had helped her move the desks earlier. She had been curious at the time why such a delicate [loli] was sent to do manual labor, but now, facing Koneko’s strong aura head-on, she finally understood the reason.
Nonaka Kurumi was a [magic] user. At this distance, facing Koneko—who excelled in close-quarters combat, she had almost no chance of winning, even if their strength levels weren’t far apart, not to mention her own power was even lower.
After a moment of standoff, with the arrival of Mittelt and the others, Nonaka Yuki finally chose to give in.
The waves of [Spiritual Power] and [Mana] faded. Kiba Yuhime’s gentle, beautiful smile remained unchanged as she stepped aside to clear a path.
”Please, follow me.”
The Nonaka sisters didn’t speak, silently following behind.
After the girls left, the [Other girls] in the classroom began to whisper, but quickly chose to forget the incident. Hamazaki Reina and the others weren’t stupid; they knew what to say and what not to say.
While the Nonaka sisters were being called by Rias, Aki and Basara Toujou had already ordered their lunch at the cafeteria, eating and chatting. Aki rarely ate at Kuoh Academy, but every time he did, he felt the taste was quite good. As expected of a private academy managed by the [Gremory household], the food in the cafeteria was not much worse than what you’d find at a small restaurant outside.
