*3rd pov* 

Ken and company finds themselves in a seemingly abandoned courtyard of the Sistine chapel. The head priests and exorcists have fled to heaven to escape the calamity. Only those who are believed to be expendable remain. 

The peace is short lived however as two sets of exorcists burst out of the front of the chapel in pitched combat. Ken recognises two of them as his childhood friend Irina, and her father. The other two, wielding strange swords that radiated holy energy, we're retreating but not before the leader delivered a deep cut on Her father's stomach. 

Irina dropped her blade and leveled down to her fallen father. The 3 attackers started to argue with themselves and one started to advance at the couple on the ground.

Leader: FREED! ENOUGH! WE HAVE WHAT WE CAME FOR!!

The man known as freed laughed psychoticly and slowly lifted his sword ready to cut both father and daughter down. Ken had enough. Ken summoned his blade and shield and charged the man threatening his friend. His charge alerted the three and freed jumped back to avoid decapitation.

Freed: Oh look more people to kill! Thank kokabiel this bloodbath can continue!! 

Leader: ... What is that blade?... FREED FINISH UP HERE WE HAVE TO GO!

Other attacker: is that wise sir? We don't have time to play around with people here. Our orders-

Leader: Lets just say that boy interests me. Let Freed have his fun, I'll stop it if he takes too long. 

Freed: You hear that kid?! I get to use Excalibur-chan here to play with you! 

{With Ken's friends}

Asia: Do we help him? He is outnumbered!

Koneko tightened her fists.

Koneko: ...I don't know if I still have my rook strength... 

She bit into her bottom lip. In her mind she considered to use IT, but she hesitated considering what it did to her sister.

Koneko: ...for now we just watch, if it looks like he is in trouble I'll step in and use... I'll help him however I can, I promise.

{Back to Irina}

Irina looked up to see her savior and couldn't believe her eyes.

Irina: Ken?!

(Quick note I'm just going to call her father "father" cause I suck at naming things)

Father: K-ken? He s -should be in Japan right?

Irina stared at him in a daze. Even though she hadn't seen him in years, she instantly recalled one of the people she could call a true friend. She spent much of her young life among him and his brother, but was always put off by Issei's perversity which started to develop at a young age. Good thing Issei never realized her gender at the time but she did end up informing Ken about it.

...By giving him her first kiss a few days before she left to Europe...

Her cheeks burned at the memory of their time together. Now here he is, dispite the rather impossibility of it all, saving her life. After she volunteered to stay behind to keep the Vatican safe, she lost hope of ever seeing him again...

Ken glanced at Irina and her father and then glared at Freed.

Freed: What's wrong? Angry I'm going to chop up that whore of the church and her bastard father? Well don't. you. worry! You won't have to wait long for your turn! You and your group of sluts can have my undivided attention! Wait... I recognize a couple of them... Is that... ASIA! I remember you. I was going to take you last time we saw each other but Raynare just had to get in the way. I'll get back to that after I cut up this boy in front of me! Who knows maybe I'll make him watch!!

Ken narrowed his eyes. 

Freed then jumped in the air and brought his sword down in an attempt to cut Ken in half but to the annoyance of the former priest, Ken dodged by jumping back. As the blade hit the ground it caused an explosion leaving a good sized craiter. 

Freed: Oh did I forget to mention that my blade is Excalibur Destruction? It will obliterate anything that it touches. So do me a favor and DIE YOU FUCKING CUNT!!

He then charged again but dispite having a legendary blade he just couldn't connect with the elf. In the other hand to Ken, Freed was both predictable and slow. 

Freed: Fine then if you don't want to fight I'll just CARVE UP THE CHURCH SLUT FIRST!!!

Freed then dashed to Irina and her downed father but Ken was faster and quickly got in front of them to protect them. Freed smirked and cleaved down again using his blades power of destruction to make Ken choose between himself and Irina. Ken made his choice and raised his shield to block the legendary blade.

Blade met shield with a earth shattering bang. The flash of holy power blinded everyone around and a dust cloud enveloped what everyone thought was a blood stain that once was Ken. The thought was short lived when the wind picked up and both Ken and his shield were completely unharmed.

Freed: WHAT?!!

Ken bashed the sword away and pressed the offence using admittingly amateur swordplay but was fast enough to keep Freed on his toes. The dishes were replaced by parries and counters. The fact that Lens equipment was not only surviving but outperforming the Excalibur quickly caught the attention of the leader of the attackers. 

Freed: THAT DOES IT YOU DICK GUZZLING MOTHERFUCKER! DIE DIE FUCKING DIE!! 

Freed summoned all the power he could from the blade and it started to glow. Ken saw this and did the unthinkable. He unsummoned his shield and held the master sword in both his hands and charged it up to clash with Excalibur. He had no idea where this plan came from but he just decided to roll with his instincts. 

The master sword started to glow as if it was excited to test itself in a clash.

Both Ken and Freed ran and there blades met in a violent exlosion. 

Ken cleaved through both Excalibur and Freeds entire arm. Blood spurt out from his shoulder as he screamed in pain. Freed then jumped back and wailed.

Freed: HOW DARE YOU! THIS IS IMPOSSIBLE YOU WERE SUPPOSED TO DIE! 

Leader: ENOUGH! We wasted enough time here! And thanks to you we lost both an Excalibur and your arm thanks to your incompetence. We're leaving. 

Grabbing Freed they sprinted away with the remaining blades. 

Father: *koff* Well Ken you sure been busy. 

Ken motioned to Asia to heal the injured man while explaining to them why they were here.

Father: Well if I hadn't seen it with my own eyes I don't think I could believe you. Luckily for you there was a theft recently and I don't think we could spare the men to stop you from searching for this shrine... Can I ask you one thing however?

Ken nodded.

Father: Can you please Irina with you? If this shrine can save you- 

Irina: Father?! I'm staying with you!

Father: Irina no. Only one of us has to die here... Because of your... condition, the church higher ups have been looking for an excuse to cast you out. Lord Michael was our last hope of he would turn you into an angel but with this failure I fear he would be overruled by the majority. Please, I know you wanted to be a soldier of God but go with Ken and survive with him. You cried every night for years after you left him before.

He looked at ken.

Father: If it was anyone else I would never even consider doing this but promise me you will keep her safe Ken. After her mother passed, she is my last treasure in this world. If it's you, I know she would be happy...

Ken: ....Yes sir.

Father: Heh, you were always the polite one of your family...

Koneko pulled on Ken's sleeve.

Koneko: Are you sure this is a good idea?

Ken: Nope.

Koneko: ....That isn't going to stop you, is it?

Ken: Not at all.

A/n I wanted to clarify a few things about the timeline here. First off raynare is still alive because she was so cartoonisticly evil in the canon that I just had to change it. In fact all 3 fallen angel girls escaped unharmed as it was dohnaseek's plan to take twilight healing from Asia here. Whether or not there in the harem is still being decided but I wanted to keep the idea open. Also for those wondering Xenovia is being protected from the calamity by heaven due to her being both a natural born holy sword wielder and carring Durandal. She was to important to risk.
