After helping collect the bounty on Toxic Chainsaw, Nagato and Konan take Kakuzu and Hidan to the hideout of the Hellsing Organization. Hidan looks around the place and isn't impressed. 

Hidan: This shit hole is your hideout?! 

Seras hears the insult and walks up to them.

Seras: Who are you calling a shit hole?

Hidan: I am Big Tits! What's it to you?!

Seras then pulls out her Harkonnen and aims it at Hidan's face while he pulls out his Triple Bladed Scythe and pointed it at her.

Seras: I'll blow that smug smile off your face!

Hidan: Go ahead and try it! I'll show you pain and the Way of Jashin! HAHAHAHAHAHAHAHA!!!!!!!!!!!

As Hidan laughs, Kakuzu restrains Hidan while D restrains Seras.

Kakuzu: I don't want you wasting my time with your religion Hidan. I want to see what deal they offer.

D: Easy Seras Victoria. No need to lose yourself to juvenile behavior.

Hidan: Juvenile behavior?! I'll show you juvenile behavior!

Kakuzu: Enough!

Nagato speaks with D.

Nagato: Is Sir Integra here?

D: Yes Nagato. She and Alucard are discussing some business in the office. They're expecting you and your new guests.

Konan: Thank you. 

After the heated exchange, Nagato and Konan lead the Zombie Duo to the office where Integra and Alucard are speaking. 

Integra: Welcome back Nagato and Konan. So your mission was successful?

Konan: Yes ma'am.

Seeing the Zombie Duo please Alucard.

Alucard: So you two must be the famous Zombie Duo. I've heard so much about you.

Kakuzu: So you're the Ultimate Vampire Alucard. I didn't think you were real.

Alucard: Hehehehehe. No one does.

Nagato: Kakuzu wishes to negotiate a deal with you.

Integra: Is that so?

Kakuzu: If you want me in on your little Akatsuki team, my services won't be free. In fact, they're....substantial. 

Integra: The Hellsing Organization will pay a generous and substantial fee for your services. The likes of which no one would be able to top. 

Hearing that deal pleased Kakuzu. The thought of that deal satisfied the greedy mercenary. 

Kakuzu: And in exchange for this generous and substantial fee, what services will I be providing? 

Integra: You will be given missions from me. I expect compliance. Am I understood?

Kakuzu: Crystal.

Integra then hands Kakuzu a dark green ring with the kanji symbol for North. Kakuzu takes it and puts it on his left middle finger.

Integra: Welcome to the Akatsuki Kakuzu. 

Hidan then groans loudly in frustration.

Hidan: I seriously don't fucking about this bullshit!

Alucard: Such fire and rage. He seems perfect for this organization!

Integra: What would it take for you to join the Akatsuki?

Hidan: Are you kidding me?! No fucking way! Whatever this Akatsuki bullshit is, I don't fucking care! All I care about is my mission!

Integra: Your mission?

Hidan: Yes! To spread the Way of Jashin! I'm not gonna waste my time with this Hero bullshit!

Alucard steps in. 

Alucard: Then perhaps I could step in. I'm familiar with the Way of Jashin. While I'm not a believer myself, I can respect it. How about this Hidan? You join the Akatsuki and in exchange for your services, I'll take you in and help you spread the Way of Jashin to my targets. That would be if you're a good boy! Are you a good boy Hidan?

Hearing that made Hidan laugh loudly and maniacally. Integra then hands Hidan an orange ring with the kanji symbol for three. 

Hidan: When you put it that way, then I'm in! But know that I'm still gonna spread the Way of Jashin!

As Hidan puts the ring on his left index finger, Integra offers him a fair warning.

Integra: When on patrol with Alucard, you are to kill the target and only the target. As with any missions of the Akatsuki, you are prohibited to kill unless given the order to do so. Under no circumstances are you to murder civilians. Doing so will be punished severely. 

Hidan: Whatever you say lady!

Integra: Then welcome to the Akatsuki.

With the Zombie Duo now recruited to the Akatsuki, Kakuzu then asks the Hellsing Director a question.

Kakuzu: What now?

Integra: We have set up personal quarters for you two. That will be all for now.

Hearing that, Kakuzu and Hidan exit the office, leaving the Orphans alone with Integra and Alucard.

Alucard: I'm very much looking forward to working with Hidan!

Integra: Keep him on a tight leash Alucard. I need a moment to speak with our operatives alone. 

Alucard: As you wish, Master.

Alucard then vanishes from a cloud of smoke. After he leaves the office, Integra hands Nagato a purplish-grey ring with the kanji symbol for zero and Konan a white ring with the kanji symbol for white. 

Integra: You two have proven yourselves to be invaluable members of the Hellsing Organization. These rings symbolize your place in not only the Akatsuki, but to the Hellsing Organization as a whole. 

Nagato puts it on his right thumb while Konan puts hers on her right middle finger.

Nagato: Thank you. We're honored. 

Konan: We couldn't have gotten here without your guidance. 

Integra: The Akatsuki now number in four members. Thanks to the UA Sports Festival, we have four more potential recruits for the Akatsuki. 

Integra then shows Nagato and Konan pictures of Itachi Aizawa, Kisame Hoshigaki, Sasori and Deidara. She then proceeds to show them footage of their performances in the Sports Festival. 

Nagato: Impressive!

Konan: Do you need us to find and recruit them?

Integra: That won't be necessary. I will see to that personally. And besides, I've sent these four an anonymous request for the internships. 

Konan: How do you know they'll accept? 

Integra: Leave that to me. I can be very persuasive. Such talent among these four would fit well within the Akatsuki. That will be all for now. You may rest.

Once Nagato and Konan leave the office, Integra prepares to recruit the four UA students into the Akatsuki.
