Devil and their troublesome request

My Servant and I walk toward Kuoh Academy to meet the devil. I know the topic the devil faction wants to ask me. They want to know about Chaldea (I keep Chaldea name for myself) and my servant identity, but I'm just guessing so I don't know the real reason why they want to meet me in Kuoh.

The one that accompanies me in their human form is Artoria, Jacky, and Lily. I didn't bring Ophis and Valerie because of their identity, and I also let Asia stay at our Mansion with them. As for the rest, I made them come with me but stay in their Spiritual Form. While walking, I start to think about the meeting. While I know, I can support all my servants all at once, even if they use their Noble Phantasm, but I can't support them for a long fight. However, if they didn't use their Noble Phantasm, then I can support them indefinitely. Ophis says that My mana is almost the same as the Dragon King she met before. So I'm proud of my mana reserve, and I guess I should thank Kirei for his Steel Training, which is very useful. Not only does it make my body more durable, but it also increases my Mana Pool quite a bit. The same with Before Awakening Craft Essence.

Anyway, I snap from my thoughts as we arrive in front of Kuoh Academy, where Grafiya is already waiting for us.

"Pleased to meet you, Fujimaru-Sama. My name is Grafiya, the maid to the Gremory Clan. Please follow me."

We then follow Grafiya toward the room where Sirzech is waiting for us. After arriving at the meeting room, I can see that all four Maou, Michael, and Azazel, are already inside the room.

"Yo, Gudako. Please take a seat."

I then took a seat that was already prepared for me.

"So, What is this about?"

Before Azazel can answer my question, Sirzech beat him first by saying.

"I'm sorry if this sounds rude, but who are you, Fujimaru-San? And which organization are you from?"

I look at Sirzech before saying.

"My name is Fujimaru Ritsuka, and I'm the leader of the Chaldea Organization."

"Chaldea Organization?"

"Yes, Chaldea's goal is to secure any harm that will happen to the human race."

"Really?"

"Yes, We are an Organization that protects humans from the harm of the Supernatural World. For example, We hunt Stray Devil that threaten and kill humans for their gain."

"...Are we also a threat to your Organization?"

"Pardon?"

"We, Devils in general. You know that we devil's search for our peerage member in the human world, right?"

"Ahhh, Yes, I know. You could say that I'm annoyed by the peerage system, but I know that you guys create it for your race survival. I can ignore it, but I still hate the Slave system you guys put in the peerage system."

"But…"

"No, no, no, You know yourself that you guys create a slave system for Peerage. So please don't try to justify it with your words."

"Very Well"

The entire room then becomes silent before Azazel breaks the silence.

*Cough*

"Gudako, We also have other reasons to call you here."

"Yes, Fujimaru-San, we need your help when the war is coming."

I look at Michael in a shocked expression. This time Ajuka Beelzebub is the one that says.

"Yes, Fujimaru Ritsuka, we need you and your allies to help defend the underworld on the incoming war against The Khaos Brigade."

"What? How do you know this?"

"We know about this information after we 'interrogate' Diodora Astaroth and get some bad news about The Khaos Brigade."

Sirzech says it while giving me a folder filled with a member of the Khaos Brigade. The first one is Rizevim Lucifer or the leader of Khaos Brigade and all the descendants of the original Satan. What surprised me, however, is Loki is inside the listed member of Khaos Brigade.

"Why Loki inside the listed member? I thought I already beat him so he can get imprisoned inside Asgard?"

"About that, we don't know how but somehow someway Loki is free."

I then look at the list once more. I look at the name and see some Evil Dragon is on the list as well. Somehow Rizevim was able to resurrect some Evil Dragon from the dead. Inside the folder also has the name of the Hero of Old. Like Heracles, Jeanne, and Cao Cao. If Heracles and Jeanne I can understand but for Cao Cao also inside the list is the one that makes me suspicious that the hero is not the one Rizevim summons with the Grail but the real person from Hero Faction.

"We, the devil's faction, will deploy our army."

"The same with Heaven."

"Fallen Angel will also send their army and finish this conflict once for all. That's why Gudako, please help us in this war."

I take a long breath as I can feel my Servant that waits for my answer. I know my Servant will follow me even though I go to the deepest of hell itself. After a few seconds, I said.

"First thing first, Why do you involve us? We are the defenders of Humanity, so why should we help you guys?"

"Because if Rizevim Lucifer is not stopped right now, then he will cause chaos to the Human world and result in the death of billions of humans around the world."

"And also we able to call Yokai Faction to help us in the war because Yasaka tells us about your help against the Shadow Servant, The same enemy that Diodora says about the Khaos Brigade Army."

"Haaaa, Very Well, we will help you guys."

What they didn't know is that my goal is to kill Rizevim in the first place and destroy the corrupted Grail from him.

"Thank you, and for the payment, we Bible Faction will give you this."

Michael then takes out a box and then opens it, revealing a Silver Cross that has a purple jewel in the middle of it.

"This is Incinerate Anthem. One of the 13 Longinus. We able to take back this Sacred Gear from Walburga, The leader of Hexennacht, a group of Stray Magician when they were attacking the Vatican to take the Holy Grail."

I look at the box in front of me with a shocked expression. How could I not be surprised? Here in front of me is one of the 13 Original Longinus that God has created.

"Are you guys sure of giving this to me? My Organization is not big, you know? We are not strong than the other Organization you guys can hire."

The entire room became silent, but suddenly Sirzech and Azazel burst into laughter.

"What?"

"Not strong, she said… Pfft hahaha"

I can see that my previous statement is amusing to all people inside the room, and after waiting for a few seconds Azazel and Sirzechs stop laughing and say.

"Fujimaru-San, your Organization is one of the strongest I ever see."

"What?"

"Yes, You have the descendant of CuChulainn on your team. You also have a descendant of Heracles. Wielder of Caliburn, and don't forget your group also has Caladbolg and Hrunting as well, and don't forget the one that wields that Caladbolg and Hrunting also has a spell that able to rewrite reality."

"Also, don't forget they have ANOTHER Ascalon."

"Ahh yeah, you guys also somehow have ANOTHER Ascalon. So, will you accept the deal?"

I take a deep breath before I say.

"Yeah, We will join the War between the Alliance and the Khaos Brigade."
