I apologize for the late update. My final exams have been happening, so I've been really busy. But here's chapter 13! Hope you enjoy!

Note: The sequel I have planned out is very different from the current one. So, I might delete the current one as well.

Chapter 13- Ariadne

(Agiel's POV)

"Are you sure this is okay, Agiel?" Furuichi asks me as we approach the metro station.

"What if it's a trap?" Lamia asks.

"If it's a trap, then I've come prepared," I tell him. I turn to Izuma, who's holding a letter in his hands. "This is where we were told to come?"

"Yes," he replies. "The metro station. This is the one with an abandoned outdoor platform. That's where we're supposed to meet him."

A few days ago, Izuma had gotten a letter from a Demon Maidservant who is apparently an undercover spy and is spying on the Kagirinai Kumori. However, the three of us are rather suspicious of this person's true intentions. In the letter, she told us to meet her on this abandoned platform at night. Fortunately, Furuichi's family isn't in the house right now.

We managed to get Lamia to help us out as well. However, we kind of made her not tell Oga or Hilda, because we don't want to worry them too much about Beelze-sama's safety.

"Is anybody there?" Izuma calls. He suddenly tenses up as we see a figure approaching from the shadows on the railway tracks.

We get into defensive stances, preparing ourselves for the attack. However, to our surprise, the figure fully reveals herself from the shadows, and it turns out to be a woman with olive-coloured skin, her bangs hiding her eyes. The woman has long brown hair tied in a side braid and she wears a long-sleeved black goth-lolita maid uniform with a white frilly apron and a white headpiece. Immediately, I recognize that this woman is a Demon Maidservant.

"I see you've gotten my message," she says, her voice soft and almost weary. "I'm glad you came. I's quite risky for me to be doing this."

"Who are you?" Izuma asks.

"There's no need to be so cold," she replies. "My name is Ariadne, and I am a Demon Maidservant working as an undercover spy." She looks around her. "Where's Tanaka Yumi-san and Hecadoth-san?" Ariadne asks.

"They're training in the Demon World," Furuichi says. "Why?"

"They're in danger," Ariadne suddenly warns. "But before I get to that, let me tell you about the Kagirinai Kumori. I had found some rather shocking facts when I had done a little more investigating."

"What is it?" I ask.

Ariadne looks down. "The Kagirinai Kumori, it was never originally an assassin team,"she starts. "It was actually an elite police force of the Great Demon Lord, that was formed by their former leader Diabolos in order to get rid of any traitors who were looking to overthrow the Great Demon Lord."

My eyes widen in shock. "Really?" I ask.

She nods. "Yes. They had helped put down several of the rebellions, and they were honoured as heroes. Their main purpose was to eliminate traitors and traitors only. However, this whole disaster started after the sudden death of Diabolos sixteen years ago."

"Does it have any connection to the sudden targeting of Izuma-senpai, Yumi, and myself?" Furuichi asks.

"It does, actually," Ariadne replies. "After Diabolos died, a new leader took over. No one knew who he was, but I have a strong suspicion that it was his son that took over."

I raise an eyebrow. "What happened? And why don't you know?"

"His son is a very cruel man, but he had moved away from the main kingdom. No one knew the leader's real name," Ariadne replies. A grim look crosses her face. "However, things took a turn for the worse after this new leader took over. The morals of the Kagirinai Kumori changed and it went from an elite secret police force to nothing more than a group of bloodthirsty assassins who killed for pleasure. Even their M.O. changed."

"What do you mean?" Furuichi asks.

She shakes her head sadly. "It's too much for me to talk about," she says. "I've seen those victims and what they go through and it's absolutely horrifying." A sigh escapes her. "All I can say is that their brutality shocks me to the core. I really don't want to talk about it."

Lamia nods. "But why are they targeting Yumi, Furuichi, and Izuma?" she asks.

"Furuichi is the contractor of the Pillar Division, so killing him would weaken them considerably," Ariadne says. "I do not know about why Tanaka and Izuma have been targeted, but whatever the reason, it all seems to be simply because of their half-breed statuses."

Lamia frowns grimly. "Looks like we're up against something even more evil than what we know of," she says. "We might need all the help that we can get."

I nod. "Tomorrow, let's go and warn Beelze-sama's contract holder and the demon maidservant," I say. "We should also get Yolda, Lord En-sama's main maidservant to help out."

Izuma smirks slightly. "And I'll try and talk Toujou-kun into helping us out," he adds.

"And we'll get the Pillar Division to help us out," Furuichi says. "Thank you, Ariadne-san."

Ariadne nods. "I'm glad to be of help," she says. "Until Hecadoth and Tanaka Yumi return to you, I want you to get rid of the posts of the Kagirinai Kumori that have been placed in the Human World." She disappears in a cloud of demonic aura.

When she disappears, the four of us turn to each other. "Does everyone know what to do?" Furuichi asks.

I nod. "Hell yeah," I say, grinning. "We can do this."

Izuma smirks. "Agreed."
