Chapter 305 Cooperation
Edited by: Kanaa-senpai
After looking through the materials from Himejima Akeno, Irina shrugged. “Even if the Fallen Angels aren’t here anymore, that doesn’t mean the Holy Swords aren’t.”
The chestnut-haired, busty schoolgirl handed the documents back, hinting, “Besides, the dates recorded by the higher-ups are from several months ago. Can you guarantee no new Fallen Angels have infiltrated since then?”
Himejima Akeno fell silent. If they were simply focused on infiltrating without causing trouble, it was true—they wouldn’t have been able to detect them.
As for why they had brought the Holy Swords into this territory? Naturally, it was because the biological younger sisters of Demon King Sirzechs Lucifer and Demon King Leviathan were both here.
The Fallen Angels stealing the Holy Swords was clearly the work of the pro-war faction dissatisfied with the peace contract. By dragging Rias and Sona Sitri into it…
If there were any casualties, the newly signed peace contract would be rendered effectively void.
Even knowing it was a conspiracy didn’t help; with three factions intermingled, the situation was impossible to untangle, and the already fragile peace could not withstand any suspicion.
”I understand. We will assist you in retrieving the Holy Swords.”
Rias looked toward the two Holy Sword-wielding schoolgirls. “However, I hope you can share the intelligence you already possess with us.”
”No problem.”
This time, it was Xenovia who spoke. Unlike the playful Irina, she was the primary force of this operation. Moreover, her special status meant that, regarding the Holy Swords, she could often make the final decision.
”If we can reclaim the Holy Swords, that is for the best. If not, I would rather see them destroyed than let them remain in the hands of the Fallen Angels.”
Xenovia said in a deep voice, “Peace is not easily won. We cannot allow those madmen to destroy it.”
The restraint Holy Swords held over Devils was absurd; even if divided into seven, a single slash was enough to render a mid-level Devil combat-incapable.
The Holy Swords were also symbols of the church, or rather, the Angel faction.
If the Fallen Angels used the Holy Swords to kill Devils everywhere, it would easily incite conflict between the Angel and Devil factions.
Upon hearing the words “destroy the Holy Swords,” Yuuto’s eyes instantly lit up. The slight trace of hostility hidden in the depths of her gaze dissolved entirely at this statement.
As long as they were willing to destroy the Holy Swords, they were her good partners.
Xenovia untied the white cloth that had been wrapping her wide-bladed greatsword. “First, allow me to introduce myself. I possess the destruction Holy Sword, specialized in attack and annihilation.”
”Mine is the mimicry Holy Sword.”
Irina then unwrapped a thin white cord from her arm, demonstrating the so-called mimicry Holy Sword for everyone to see.
Put simply, it was a weapon that could change into various forms. She typically used a whip or a katana—the two forms she favored.
Of course, regardless of which form it took, it possessed the restraint against Devils.
”Um… I have a question.” Aki looked curiously at the mimicry Holy Sword as the girl tied it back around her fair, slender arm. “Does it turn into anything? Like clothes or pants?”
Irina looked at Aki strangely. She wanted to hold it in, but couldn’t help but retort, “I mean, it can, but why would you want it to become clothes or pants? You wouldn’t be able to use it for battle that way, would you?”
”Why wouldn’t it be able to fight?”
”Huh? Do you want me to fight the enemy while naked?”
Aki spread his hands. “You guys usually have your clothes shredded during battle anyway. Turning into clothes or pants might actually catch the enemy off guard.”
Irina’s face flushed red, and she said indignantly, “Who gets their clothes shredded? You’re the one who does that!”
”I do get my clothes shredded, but I have armor.”
As he spoke, Aki was instantly enveloped in a handsome red dragon armor, though it dispersed the very next moment.
Irina fell silent, stunned by the powerful aura that had flashed from Aki just now.
Xenovia stared at Aki intently, hesitating before saying, “So, you are the Red Dragon Emperor. Have you already fully mastered the Balance Breaker mode?”
”Just address me normally.”
Aki waved his hand. “I specifically sought you two out today not for anything else, but for the matter of the Holy Swords.”
”As Holy Sword wielders of the church, you should have heard of the Holy Sword Project, right?”
”Hmm…”
”Good that you know. This person beside me is the sole survivor of the Holy Sword Project.”
Aki pulled Yuuto over. “Her goal is also to destroy the Holy Swords—or rather, she has always been obsessed with destroying them. Since you have expressed that the Holy Swords can be destroyed, we will give this mission our all.”
”Um… if it’s possible, I would still prefer to recover…”
Aki interrupted Xenovia’s words rudely. “That’s settled then. Give me the detailed intelligence. As long as it’s within Kuoh Town, I can track them down within at most three days.”
He already understood the majority of the situation, and he was too lazy to waste any more time.
Besides, for finding people or things within the Kuoh neighborhood/town/street, he had much more convenient channels.
Irina and Xenovia exchanged glances and raised no further objections.
”The Fallen Angel executive who stole the Holy Swords is Kokabiel. The three Holy Swords are… these are photos of the stolen Holy Swords…”
Irina laid out all the intelligence they possessed. With the peace contract already signed, they and Aki’s group were naturally on the same side to maintain that peace.
Aki listened while extracting key information, then sent it to Takamine’s mother and Sakuramachi Touko.
He was a “hands-off” boss who rarely managed the organization, serving only as the “prize” and spiritual symbol, but both organizations had developed quite well.
They were gradually becoming a full-fledged corporate group, encompassing logistics for both the supernatural and normal worlds, as well as security contracts (commissions) and other businesses.
Interestingly, one side leaned toward Chaotic Good, while the other leaned toward Lawful Evil. Sometimes, both companies would receive conflicting tasks.
Well, it was also possible that someone was trying to do something behind the scenes.
However, the upper management of both sides always communicated. Whenever tasks conflicted, whichever side would gain more profit took priority, and the other simply dropped it.
As for the client being dissatisfied… if they didn’t find any issues, that was fine; if they did find issues, there would be no more clients.
”Alright, for now, we just have to wait for news.”
Once Irina finished speaking, Aki distributed the tasks.
Outside the window, the setting sun gradually dipped below the horizon. Aki put away his cell phone and invited them, “It’s getting late. Why don’t the two of you stay for dinner?”
Irina was just about to refuse when Xenovia stepped on her foot under the table without a sound.
The short-haired schoolgirl’s fair, tender face flushed slightly as she said shyly, “All right, then I’ll trouble you. If it’s possible, we would like to borrow a room for the night as well.”
”Of course, no problem.”
Aki said happily, “There are plenty of empty rooms here. You can pick two later.”
”No, no, one is enough. Irina and I will just sleep together.”
”As you wish.”
Aki laughed and took the lead as a guide, touring the two girls through the first to third floors while deciding on their room for the night.
Yuuto had wanted to follow but was sent away by Aki; he still wanted to take the opportunity to cultivate their relationship further.
Rias and Himejima Akeno notified Sona Sitri of the situation, so she could be prepared just in case.
”This is the end of the third floor.”
Aki pointed toward the stairs and said, “If it’s not necessary, you two had best not go up to the fourth floor.”
”Why?” Irina asked curiously.
”Because the entire fourth floor is my room. I’ll be having SEX with Buchou or someone else anywhere on the fourth floor.”
The three major factions had all collected intelligence on Aki. Irina and Xenovia didn’t know the specific details, but they were generally aware of the situation.
The busty girl with chestnut twin-tails instantly blushed, though her eyes held a hidden desire to investigate further.
Xenovia, being more straightforward, was even more blunt, saying with a tone of regret, “SEX? What a pity you’re a Devil, otherwise I’d really like to try it with you.”
She had a very good impression of Aki: handsome, powerful, and unpretentious—perfectly matching her requirements for a spouse.
”Why wouldn’t it work just because I’m a Devil?” Aki smiled slightly. “We’ve already signed a peace contract, after all.”
Xenovia was taken aback and subconsciously began to think about it seriously.
”Hey, Vya!”
Irina grabbed her shoulders and shook her violently. “What are you thinking? Don’t tell me that’s why you wanted to stay the night!”
”That’s not it.” Xenovia retorted instinctively, “If you hadn’t used all of our room and board expenses to buy that useless fake painting, I wouldn’t have been shameless enough to beg for shelter.”
”It’s not a fake painting! It’s a work of art, a tribute to God Akira!”
Irina put her hands together, her eyes sparkling—the spitting image of a pure fanatic.
Her personality was naturally lively and simple, and the environment and educational atmosphere of her household had cultivated her faith from a young age; it was only natural she would end up like this.
Aki wanted to tell her the truth—that God Akira didn’t exist—but after a moment of thought, he decided against it. Irina would absolutely never believe him, and she might even start making a scene.
