It was two days since their encounter with the G Class Stray as the peerage was still in hot waters as they didn't kill the Stray, therefore the church said that it didn't count.

'What was he trying to say…'

[Still thinking about that?]

'Yes, something felt wrong'

[I didn't feel anything until he was attacked, and there was something wrong with her…]

'And she's Passionlip's sister'

[She's way more powerful than your familiar, and if she's a threat to us, we may have some troubles to fight her]

'Great, what the hell are we supposed to do?'

[There's someone who can help]

'no'

[You do know that he will come to see you one day or another]

'I know, i just hope its later'

[I'm just waiting to see how fun it's going to be for you to withstand him and his… way of talking]

'Wow, where did that come from?'

[I got that from you. Guess that your sadistic personality began to detain on me]

'I'm going to blame that on the Fallen'

[Why not go outside and see if you can do something right for once]

'That's mean'

[I know]

XXXXXXX

'Hey...do you feel that?'

[yes, and I don't like it]

'Neither do I'

[Do you think that the Fallens are back?]

'I don't know, but I want to find out'

[Why not go with someone? Unless you want another problem that will fall on the heiress]

"Sure, I guess"

[As long as it can help you to stay out of troubles…]

After a while, Koneko was here… with Issei.

"Why is he here?"

"You can always use him as an excuse if something bad happens"

"Fair enough"

[That power I felt was somehow familiar, but I don't fully remember]

(Markus)

[It wasn't like the power of that human, but something darker]

'great'

[If you find yourself in danger, run away]

'Very funny'

[Comedy was always my forte]

'liar'

"Senpai, do you think it's the same priest like last time?"

"I doubt it"

"What would happen if it happens to be something related to the church again?"

'Could it?'

[Unless the church is working with dark magic, I can't say that's true]

'What about the priest?'

[I give you that one, that priest was full of Void Energy]

They all headed to the abandoned church. When they arrived, they saw a single person kneeling in front of the broken cross.

"Welcome to the house of God" stated a nun as she turned to them.

"Ohhhhhhhhhhh!" yelled Issei as blood began to fall from his nose "A hot smoking woman with boobs and wearing a nun outfit! The perfect combo!"

Markus sighed.

"Why did you bring him?"

"Shut up, perfect boy! You already have Buchou and Akeno-san! You won't get this one!"

"Who said I was perfect?"

[Now, I think that it wasn't a good idea to bring him here]

'Yeah, same here'

[Just hope that it won't get you in more troubles]

'Thats a lot of hoping'

"Let me present myself" said the nun with a gentle smile "I'm Sister Agatha, I was sent here to help with a Devil problem"

"Devil problem?"

"I've been told to give you the name of a Stray Exorcist that was roaming around here"

"The guy with white hair? I killed him already"

"This one is more powerful that Freed"

"ok…"

"His name is Alexander Anderson. Kill him, and the church will forget that ever happened"

"We'll get right on that, lets go, pervert"

"You can come out" said the nun in a different voice that felt like there were many voices mixed together.

"Sending him to buy us time, I didn't know that you were this crafty" stated a creature with four arms, strange armor, and glowing blue eyes.

"We need to search this place for it" stated the nun "I just bought to us a bit more time than what we had"

"Are you sure that's going to help us?"

"You want that weapon, and I want a host for the Heart. I guess that's a win-win situation"

"I don't think that it's here"

"I know that it's here" said the nun as she looked at the cross before her arm transformed into a hammer and destroyed it.

"I thought that you were supposed to be the religious type"

The nun walked and took a box from the debris before smiling "This is going to be an interesting hunt"

"I totally agree with that"

XXXXXXXXXXXXXXXXXXXXXXXXX

Markus led the small group on a search for this rogue exorcist.

"I don't like it" Koneko mumbled as she walked while looking down "Something felt off with that nun"

"What do you mean?

"She didn't smell like a human"

"Hey! Don't say that about that bombshell! You're just jealous that you don't have boobs like hers"

Markus grabbed Koneko by the back of her outfit before she could kill the pervert.

"I just said things as they should be"

"Guys, look"

"Here he is" whispered Issei.

"careful"

"All what we need is to follow until there's no one around, and then we will hit him pretty hard"

[Shouldn't you tell him that's a stupid plan?]

'Where's the fun in that?'

[Yeah, it will be funnier to watch]

The group began to follow the man until he stopped in front of the school.

"May the Lord grant to these tainted souls mercy" mumbled the man in an Irish accent before throwing a large blade at each one of the group.

Markus was able to doge, the other two werent so lucky.

"Look at this, an abomination of the Devils. Are you sure that you want to do it?"

"You attacked us first"

"A fair point, but be ready to taste the holiness of these blades that the Lord granted me"

Markus easily dodged the thrown blades, the charged in

"Even monsters like yerself possess courage, I'll admit it" said Anderson before taking a blade in each hand.

Markus summoned his own sword, but missed and was struck instead.

He really wasnt lying about those blades…

"AGH-AHH"

"I love the sound of abominations in agony"

'Damn it!'

[Call Passion]

'No, not after last time'

[These blades are empowered by holy power, you need to remove them from those two or they will die]

'fine...fine'

"W-What can I do to help, Master?" asked Passionlips after appearing.

"That guy has holy blades"

"A-Alright"

Markus got to the others and removed the blades.

"What's going on here?!"

Both Rias and Akeno were here now.

"Someone from the Church told us to kill this guy"

"Are you out of your mind?!" Rias wasn't happy "This is father Anderson, the one sent by the church!"

"wait...what?"

"I try to see if he would still like to help us to get the forgiveness of the church and avoid a war"

'What the hell is going on?'

After some minutes, everyone was sitting in the clubroom; rias was sitting on a couch with the members of her peerage standing behind her, and Anderson on the other couch.

"I'm… really sorry for what happened" said Rias

"Devils won't change" chuckled the priest before taking some papers from his pocket "Since Kotomine won't be helping me on this, Yer to take his place. We were sent to hunt two monsters; one that can change forms Double, and one who follows it around. One of its most popular form is Sister Agatha"

[It seems like the cat was right]

'Well shit…'

"It was searching for a powerful object called the Heart"

"The what?"

"The Heart is alive and searching for a host, it doesn't matter if it's dead or alive"

"What does it do?" asked Rias.

"It can summon a powerful Demon that can annihilate all form of life on this planet. That's why the church hid it here, hoping that Double won't find it. But if she was here, then she must be gone for a good amount of time"

"Is there a way for us to help?"

"You may try to find a rogue researcher who goes by the name of Valper. You can bring him dead or alive, yer choice"

[You're definitely going to bring him dead]

'The fun way, you mean'

[Maybe that you should search for him alone since it's your fault that all of that happened]

'how was I supposed to know that she was the daughter of some Church bigshot?'

Later that night, Markus was looking at the moon before hearing something.

"What was that?"

[it came from those bushes]

Markus dropped from the roof and summoned his sword.

"Whoever you are, you better come out"

The bushes rustled and someone fell out of them, someone who was injured, and unconscious now.

Markus didn't move.

[what are you waiting for?]

'That...that sword...i can't move while i'm looking at it…'

[that was the blade used to slay me…]

'Oh shit…'
