Plot and Reality

---- Earth, Japan, Town of Kuoh ----

-- Third Person POV ---

-- At the night --

There were four cats that were loitering around the town, these four cats were none other than Touru, Kuroka, Shirone and the newest member was Aika Kiryuu the wielder of Sacred Gear Longinus: Telos Karma. Even in light Novel or fanfiction Aika was never shown in the story that she has that kind of Sacred Gear, with that she become a hot potato in Supernatural World.

Telos Karma is one of the thirteen ranks Longinus which was created by God of The Bible. Telos Karma is a very powerful Sacred Gear which many users have been hunted down for it.  Hosts of Telos Karma have been referred to as People with the Devil's Luck. Few users realize they have this due to the luck being unnoticeable to them but not to others

Fortunately he was a Super Class Youkai, he can protect her for those kinds of people. Her overall strength was in the peak of Low-class Youkai who could par in Middle-Class Devils, because of the Artificial Mutation Pieces Project that he found in Naberius clan that he took. He was able to transform all Pieces in Mutated series, even the King Pieces along the other set of Evil Pieces.

Four of them was watching the incident in church, were three peerages of Rias Gremory was assaulting the church to save a certain nun from a group of Fallen Angels and a large group of Stray Exorcist. The peerage was Issei Hyoudou, Yuuto Kiba, and a Loli dog Youkai, yep the last one was different as Shirone did not become a peerage of Rias during the incident in the Naberius lab. How the four Nekoshou knew why the last one is a dog Youkai, because of scent that emitting was beastly and the same scent of the nemesis of the cats.

Issei's Sacred Gear was Twice Critical a degraded version of Boosted Gear, the color was the same in the canon. About Freed Sellzen? Touru uses a Soul Tracker to him, in case that the Excalibur Arc happened. He can find him and the Excalibur Pieces, he collect it for himself than give it to incompetent people in the church, to him a very few people like Vasco Strada and Griselda Quarta was an exception among them.

The four Nekoshou was watching only beside the window of the church, they were so close at the scenario as they were inside of the Isolation Barrier which even a High-Class Devil like Rias will not notice it much less the three Reincarnated Devils and a group of Stray Exorcist who are only a strength of Low Class.

--- FlashBack ---

Touru took interest to collect the Excalibur Pieces as if the voice in the Sword was calling him. It made a bit of time for him to have a conclusion that his biological father in this world was related to the Pendragon, meaning the current Arthur and Le Fay Pendragon were his distant relatives.

" What a plot twist huh," he said as he was holding the Excalibur Deflection on his hand.

--- Flashback End ---

-- In Issei side --

The four was watching the incident, as they saw the Sacred Gear of Issei started to evolve in his hand. The structure of the Sacred Gear was a bit elongated large barrel on the top of his Gauntlet, the Gauntlet was covered his entire arm like a mechanical arm and there were four green orbs embedded in two each side of the barrel.

{ Quartet Critical - Artillery }

" Huh what happened?" Issei said as he look at his Sacred Gear.

{ Hmm so you are my current host huh, welp just focus on your enemy later introduction Let Explode together!!!} a male voice could be heard but his word in the last sentence was making everyone sweatdrop included the four Nekoshou in the Isolation Barrier.

" Don't tell me he also reincarnate here." Touru in cat form said as he was familiar in that voice, it was a voice of Explosive Maniac in a certain Shinobi World.

" What do you can defeat me I already have a Twilight Healing in my hands, I will obtain immortality and I will gain the recognition from Azazel-sama!!!!" Raynare said as she equipped the two rings to her finger as the starts to glowing on her hands. Which is cause to fuel the Issei's rage?

{ Boost }

{ Boost }

{ Boost }

{ Boost }

The repeated voice could be heard as the four green orbs in Issei's Sacred Gear started to glow as there was unknown energy in the mouth of the barrel.

" {Art is Explosion!!!!} " Issei and his Sacred Gear spirit roared together as he aims the large barrel to Raynare and shot the unknown energy to her.

* Boooooommmm!!!!!!!*

A loud explosion could be heard in the church, there was a large hole could be seen in the basement of the church which is the Sacred Gear Extraction in the place. Raynare was turned to ashes as only the two rings were remaining above of it, the two additional devils came which is Rias Gremory and Akeno Himejima.

Issei cannot move his body as he was out of energy, all he can do was to watch the nun lying in the floor lifelessly. He was pleading to Rias if she can revive the called Asia Argento into a Devil, the latter have no choice but agreed as she walked near in Asia as she took out a Bishop Piece.

" From now on she will be your responsibility understood?" she asked again him which is the latter nodding quickly. After a minute later, Asia who was covered in crimson light was starting to recover which is currently holding the Twilight Healing ( A/N: Akeno pick up the Twilight Healing and put in Asia hands). She opened her eyes as she was shocked that she was still alive, she suddenly clasps her hands as she started to pray which is earned her and the other devils around her a headache. After that they heard something footsteps that moving towards them.

" Well well, the Devils were praying together and gain pain together." the voice said the when Rias and her peerage turned around as they saw a four cat, which suddenly transform into a human form.

" What are you doing here Kamagiri-san?" Rias said as she earn a shrugging from him.

" Hmm we do our job as an Observer of your management in this town, as we will report it to Shinto Pantheon as you will be graded if your not doing your job, then bye-bye to this town," Touru said while looking at Issei's Sacred Gear who's the was unconscious.

" Deidara isn't?" he said to the Sacred Gear.

{ Oh you know my name } Deidara said with surprise.

" Yeah I don't know that you here," Touru said as he was hinting in double meaning.

{ So you also like me huh.} Deidara said with understanding expression (if he has a face)

" Let's meet again next time," Touru said as he turned around and left the church while the other three was followed him
