"Hey Azmuth, I'm here with my daily report, I reached the safe house here in Kuoh Town. Also, when I reached here, the ultamatrix went all invisible mode and it became... invisible. Well, see you later Azmuth, bye." said Ben the hologram Ben as Azmuth saw.

"Well, the kids okay, now to my meeting" said Azmuth as sat on his desk to find a video call with Rias's household and Sirzechs.

"The Great One as you call him has reached his destination." announced Azmuth, "Dagon will be killed."

"Does he have control over the Celestesapien?" asked Sirzechs. Azmuth nodded.

The household of Rias gasped.

"How could he have control over a celestesapien, we though that it was impossible" said Akeno, her Queen piece.

"No it isn't, he does have control though he has locked it, he may unlock it whenever he needs" said Azmuth

"May you tell us his identity, It will be easier to get in contact with the Great One, please" asked Rias.

"That Master Gremory, I cannot tell you. He has never wanted anyone other than the trusted to know about his identity." replied Azmuth.

"Well then, we will inform you when the Great One arrives, thank you for your time Azmuth" said Sirzechs as he exited the call along with Rias.

The next morning was a stressful one for Ben. He was almost late to his new 'school'. There he had to take on his fake identity where he was a boy named Issei Hyodou. He also learned that this school was just an all-girls school at one time but now turned co-ed.

"Uhh, why does High School suck" said Ben as he was stuck in his civics class with all the girls staring at him. He also met two perverted boys. Though Ben wasn't a pervert, he still had a liking for them.

"Riiiing Riiiing!" The bell had rung and this period was over.

"Huh, Finally!" exclaimed Ben as he exited out of his class.

There he spotted two girls on each side. He did not realise there were two people behind him until.

"That's Rias Gregory, the prez of the Occult Research Club and that's Sona Sitri, prez of the Student Council. said the two boys.

"Aaah! What the fuck man, don't sneak up on me like that!" said Ben

'Wait' thought Ben. 'Sona Sitri, Rias Gremory! Wait weren't those two my old friends, yeah I should go talk. Wait no identity revealing. Well that sucks'

Ben then left to go attend another class but he did not know that a certain red-haired girl was looking at him.

After a few hours, the members of the ORC or the Occult Research Club gathered for their 'club'.

There we ses Rias's peerage. Akeno the Queen. Kiba and Xenovia the Knights, Koneko Toujou and Rossweisse the Rooks, and Asia Argento and Gasper Vladi the Bishops.

"Akeno, I need info on that Issei guy" said Rias

"Oh he is Issei Hyodou, a new student, 16 years old and that is the only info I know." said Akeno

"Well, he seems familiar although I have not known any Issei before, that might not be him, that might be a fake name. Oh what am I thinking but still guys, keep an eye on that guy, I felt something very powerful near him." said Rias

"Will do Rias" said everyone except Gasper.

"Well now everyone get ready, we have some company to deal with" said Rias as they ready to go 'take care of' their business.

Back at Ben's home the guys his doing homework.

"Uhhh, why do I have to do this shit. It's a pain in the fucking ass!" said Ben as he did his homework.

Rias and her team are now at an abandoned storage building as they prepare to fight something.

As they enter, they see the fallen angel over there waiting and itching for a battle.

"Ah, the Gremory sister. Well then let's battle. come on out my fellow fallen ones." said the fallen angel as 4 others came out.

"Four fallen angels, holy shit" said Kiba

"Well then prepare for a fight." exclaimed Rias.

"Thunder" exclaimed Akeno as she fought with one Fallen Angel.

"Holy Sword, Duraldon!" exclaimed Xenovia as she summoned her sword along with Kiba using his to fight another Fallen Angel

"Let's go, Koneko," said Rosswiesse as she and Koneko used their powers to fight another Fallen Angel.

"I'll take care of this one, you two stay back" said Rias as Asia and Gasper backed up

"Stay safe Rias" said Asia

"Ohhhhh, I'm scared, these monsters make me scared." said a terrorised Gasper.

The fight went on as they fought with all their might. But only one was defeated. Rias called for help as Sona, Tsubaki and Saji arrived to help.

But that also was in despair as they all were overpowered and more fallen angels appeared.

"Rias, contact your brother, he might help you or maybe send some back up" said Sona

"Right" said Rias as she used her powers to contact Rias.

"Brother, we need backup. My peerage has been defeated and so has Sona's, please send help." said Rias

"Oh I see, please hold on for a few minutes, I get some backup." said Sirzechs as he now contacted our very own Azmuth.

"Dear Azmuth my friend, please help my sister with some help from the Great One, I promise she and her peerage can be trusted." asked Sirzechs

"I will ask him, he might take a while but he will come, please do not worry." said Azmuth.

Sirzechs has again contacted Rias

"Rias, he is coming" said Sirzechs

"Who!" asked Rias

"You'll find out when he comes but hold on for a few minutes." said Sirzechs

"Alright everyone, backup is coming, we need to hold on for a few minutes." announced Rias as both factions fought the Fallen Angels.

Back with Ben, he is taking a huge walk, exploring the city. His watch comes out of invisibility and blinks. Then Azmuth comes out.

"Ben, the fellow devils need help, I will send you coordinates and please unlock master control before you fight, your opponent has many strengths and weaknesses so full power may help you."

"Okay Azmuth, I'll do my best," said Ben as he ran towards the coordinates.

"Rias, we can't hold any longer" said Akeno

"No Akeno, please he'll be here in a few just a little longer." said Rias.

Thud! The door of the warehouse opened.

"It's been a long time hasn't it Rias, you too Sona" said the boy in the shadows.

As he stepped in, they all saw the boy in the emerald Jacket with the 10 and the Great Weapon on his left hand. Rias and Sona were still confused though in who it was.

"I'm not surprised you both don't remember me, well this might make you remember." said Ben

"Ultamatrix, unlock Master Control, code zero, zero, ten, zero, Tennyson, Ben."

Rias and Sona gasped "Ben!"

A beam of green light shot out of the Ultamatrix.

"Voice approved, Ben 10, Master control. unlocked. Welcome back Ben." said the Ultamatrix.

"Alright sweet but now it's Hero Time!"

said Ben as he dashed through the fallen angels as he dialed through his dial pad and chose the Crystalsapien.

The beam of green enveloped Ben as he transformed into the Purple Alien.

"Chromastone" called out Ben as he shot the beam of crystal emery towards the fallen angels
