===[Meanwhile At Union Academy Headmaster Office]===

Ozpin and the rest of the Headmaster in their office thinking of a plan how to bring Y/n back to the Academy, but knowing how difficult to find him.

Nezu: "There have to be a way to bring Mr. Y/n and Miss Velvet back. And when we do find him, we'll able to stop Salem and All For One along with their Villain Academy."

Sirzechs: "Don't worry about that part Nezu, I already have his location and i know a way to bring both of them here."

Everyone turned their attention at Sirzechs as he pull out his scroll and show the rest of the Headmaster where Y/n living.

Sirzechs: "I send some of my soldier to looking for him quite sometimes now and this afternoon my soldier send me some of the picture to his location but the problem is that his mansion protected by a very very strong barrier and the devil i send just came back with bloody wounded badly with some sort like a gun shot but the bullet very big..... Bigger than any bullet i ever seen, so i think Mr. Y/n has his mansion fully lock down."

Hanzō: "Alright, now we know where's Mr. Y/n. I'll send out my Shinobi students. 'Hanzō team, Gessen team, Hebijo team, and Crimson Squad' to grab his attention... Hmmm? What is that?"

Suddenly the entire Academy starting to heavy earthquake, all Headmaster trying to hold themselves until they hear a loud growling coming from Union City just outside the Academy.

Ozpin: "W-what was that coming from?!"

Ozpin asked and suddenly their office door been kick open and review Ironwood with his weapons on his hand.

Ironwood: "Ozpin! We been attack by a monster at the south side in Union City!! Some of the students is on their way over there!"

Ozpin then look everyone in the office nodding his head as rest of the Headmaster also Nodded.

Ozpin: "What are we waiting for?! Let's Go!!!!"

===[Back At Y/n Mansion]===

Y/n just walking around in the long hallway inside his mansion remembering those days all punishment, brutal beating, and neglect that he has been through. Y/n didn't want to kill all of them, do to the oath that forbidden him to kill everyone that has bullies him.

Arabella: "Master, is everything alright?"

Y/n didn't even turn around to look at the person, because he already know the voice of Arabella who's standing behind him, as Arabella place her hand on Y/n shoulder to comfort him.

Y/n: "(Sigh) Just been thinking about what happened back 4 months ago at my old Union Academy just all."

Arabella: "Master, once i have my hands on those fake hero neck who hurt you... I going to make them pay ten time pay for hurting my master. You don't deserves that kind of treatment"

Y/n nod his head at her, until he feel something wrong as he then raise his hand up creating the holographic device at Union City.

Y/n: "Just as i thought, Union City it been under attack. I want you to call Jeannie and met me at the south side of Union City to clear that threat."

Y/n order Arabella to bring Jeannie with her to save Union City.

Arabella: "Master, why do we help the Union City? Isn't that suppose to be Union Academy problem?"

Y/n: "No... It's my duty and my oath to help anyone that can't fight. I also wanted to show those from Union Academy who don't know how to treat a person who is weak with respect... Now enough questions. We got job to do....... Arabella bring Jeannie D'Arc Alter with you"

Arabella nodded her head and left to call Jeannie D'Arc Alter, while Y/n continue to look at the window inside of his mansion before creating a portal and walk inside of it as the portal close.

===[South Union City]===

At the south Union City, it was totally disaster as the half of the south city were destroyed and people were still running aways from Trihexa, also know as the Apocalyptic Beast was destroying the south Union City. Meanwhile for Union Academy, was having very very hard time going up against The Apocalyptic Beast.

Homura: "How does this fucking ugly thing still this strong?!" Homura, the squad leader of Crimson squad.

Katsuragi: "This thing is not the one to be cocky against-"

Katsuragi was going to continue her talk until everyone from Union Academy heard someone praying not one but two.

"Sink into a heap of corpses. Collapse! | This is the howl of a soul filled with hatred!"

Izuku: "Where's that voice coming from?"

Bakugo: "HOW THE FUCK SHOULD I NOW! YOU GREEN HEADED FUCK!"

Sona: "Why do i having the feeling of that voice... the voice it like full of hatred."

Rias: "I don't know, but we have to stop that mo-"

"Excalibur Morgan! | La Grondement Du Haine!"

Two massive energy both have red beam hit The Apocalyptic Beast making the monster scream in pain.

All Union Students was in shock to see two beam hit Trihexa and turn their attention where the beam shot from and they saw two girl wearing their full body armor and the Union notice both of the girl have yellow eyes, the one on the left her hair tie like a dumplings and on her hand she holding a sword with red and black color. And the one on the right her hair was short near her neck and on her hand holding two weapons, on her right hand she holding the 16th century french sword while her left hand holding a flags.

Midnight: "Who are those two doing?! They're going to get themselves killed!"

Midnight shouted as Sirzechs immediately recognize two girls and right away turn pale and scared.

Sirzechs: "Those t-two... Are Arabella Alter Pendragon & Jeannie D'Arc Alter!!!"

"NANIIIIIIIIIII!!!!!!!!!!!!!!!!!!!!!!!!!!!"

Nezu: "Sirzechs! You saying those two name is Pendragon And D'Arc?!"

Kiba: "H-how can that possible!? I thought they just a myth!"

Xenovia: "The wielders of Excalibur & The wielders of La Grondement!!!"

Rias: "Oni-sama! How can you be sure those two are Pendragon And D'Arc name?!"

The Union was now even more shock to know their savior is 'Arabella Alter Pendragon & Jeannie D'Arc Alter' were helping them fighting against Trihexa.

Before Trihexa can attack Union again, a green laser blasts hit the Apocalyptic beast right at the chest, causing the beast to stagger in pain. Next, came a strong pulse eminated from somewhere. It was so powerful, that even all of Union students, teacher and Headmaster stopped fighting to gather themselves from it. When the pulse was gone, the sky surrounding the city had suddendly turned to dark night.

Issei: "HOW DID THE SKY TURNED TO DARK ALL THE All Sudden?!"

Saji: "HOW the fuck should i know?!?!"

Coco: "Wait! (Everyone looked at her) you guy hear that?"

Then, there was a lound goging sound. It was like the Big Ben bell. Everyone turned to where it was coming from, and found it.

A large green clock had appeared in between *Apocalyptic beast* and the Union, with candles lighting all the way up to it.

All Suddenly Union felt a power that made them tremble, shaking and fear. Even Trihexa The Apocalyptic Beast shaking in fear

Then Y/n appeared in front all of them as they weren't expecting Y/n to be here and even more surprised he wearing a black and gold Tuxedos suits.

Glynda: "What is your business here Mr.Y/n".

Ozpin: "Did you come to help us?"

Y/n: "Help you? Why would i help you people?"

Weiss: "If you not gona help us then move the hell of our way then!".

Y/n turned his head around and gave Weiss a very very serious Death Stare right at her eye, as his eye was turned Red Blood Eye which sending fear into her and make her shut her mouth.

Y/n: "One more of your comment and I'II show you, who's the weakest."

Y/n turn around and look up Trihexa as Trihexa stomped on him where he stood at without care of the World

Union Studen smiled to see Y/n die for good. But they heard a voice under Trihexa feet and a music.

(Video start from 0:00 to 0:55 and end)

"It's time for Your judgement."

*GACHOON*

*Kamen Rider Chronicle*

https://youtu.be/nRNBlUV3SXw

*GASSHATO!*

Y/n: "Henshin"

*Buggle Up! Ten wo Tsukame Rider! (Wow!) Kizame Chronicle! Ima koso Toki wa Kiwamareri! (Wow!)*

Azazel: "Everyone look at under Trihexa feet!"

Eveyone look at Trihexa feet and saw Y/n holding The Apocalyptic Beast Foot that was stomp on him full force, but he also wearing a Full-Body armor that had Green and Black Color.

As Y/n threw the beast with extremely super incredible Strength.

Yang: "How he have that much strength!!"

Issei: "No way that fucking loser have that much power!!!!"

Y/n create a certain distance and looking at The Apocalyptic Beast. Y/n pressed both Red and Blud Buttons.

*PAUSE*

A shockwave burst from his body to the surroundings. Immediately, everything and everyone around him froze in place even High Class Devil and Satan Class can't even move.

Cronus lowly walk up to Trihexa and placed his finger near his lip and made a *sshhh* finger.

Cronus:"Ssshhh. Now you're in order It's time for Your judgement."

(Start the video again at 1:21 to 1:53)

*GACHOON*

Cronus: "Trihexa Your Destruction End Here."

Cronus then Pressed the B button on his Zwei two time.

*KIMEWAZA! CRITICAL CREW-AID!*

A hologram of clockwork appeared beneath Cronus before Y/n performed a powerful reverse roundhouse kick on The Apocalyptic Beast with his feet growing with energy.

The result was a frozen sphere energy on Trihexa and the clock hands stopped at the XII.

*Shuuen No Ichigeki!*

Cronus: "Trihexa Your Time Is Now Over."

Once it's done, Y/n pressed both buttons on the Driver again.

*RESTART!*

Time began to resume as the frozen midair duo flew away while The Apocalyptic Beast was blasted off by an explosion. The Union gasped for air as they looked around fanatically to find The attackers and found that Trihexa literaly kill by one attack while everyone shock as Y/n standing right in the middle of the street.

Everyone: "HOW THE HECK IS HE THAT STRONG!?!?!?!"

Cronus slowly turned around to his former Headmaster, Teacher and Classmate while still in his Cronus Form with none interest eyes inside his helmet.

Cronus: "Well then, That's all i done for. I shall take my leave."

Issei: "You not go anywhere you wea-."

When Issei try to charge into Y/n, he was stopped by two people coming out of nowhere and standing front of Y/n when he return back into his Tuxedos suits.

Arabella: "My king are you hurt?"

Everyone: "KING!?!?!?!?!?!"

Y/n: "I'm fine, nothing can hurt or kill me that easily."

Jeannie: "Arabella, you do know our King is not easily to get himself get killed by a bug under his feet right?"

Arabella: "Yes, I know Jeannie"

Jeannie: "~~~Awww~~~, i was hoping to join the fight but our King already cleaned the ~~mess~~"

Arabella: "That's why we all love our King."

Y/n: That is also why i love both of you girl." putting both arm around Arabella and Jeannie waist, pulling closer and their head lean on Y/n shoulder.

Issei: "Hey you two! how about leave that weakling and joi-." Arabella and Jeannie gave Issei the scariest ever seeing as he trying not to piss himself.

Y/n then kiss both Arabella and Jeannie on their lips making both girl smile and a bit blush.

Issei: "No fucking way!! that weakling have those two chick?! I suppose to be the one have them!" Because of that cause Y/n stop where he stand and turn around look at the Union especially Issei.

Glynda: "Young man, do you know how much dangerous it is to fight Trihexa alone on your own!" Glynda walked up in front of Y/n as his eye slowly looked at her with no emotions.

Y/n: "I defeated Trihexa in 30 second and how long did all of you tried to defeat her? for over one Hours and still not get the job done, i disappointed in all of you people."

Sirzechs: We did all we can and try our hardest to defeat Trihexa." Y/n shook his head left and right with disappointed emotion.

Y/n: Try your hardest? don't make me laugh. Only the weakling try our hardest in all the battle and to think that i just a nothing but a students who get bully all the time"

Yang: "WHAT DID YOU SAY?! Don't make me beat the Fu-"

Before she could finish her sentence. Yang was stopped by 'Arabella & Jeannie' as the two jump in front of Y/n as their 'Noble Phantasm' ready in full charge.

Jeannie: "Look like they want a second rounds, my Master."

Arabella: "Master, just give us the order."

Y/n: "Stand Down You Two"

Y/n slip both of his arm around 'Arabella & Jeannie' thighs and slowly move down to their ass robbing their butt to calm both girl down.

Ozpin: "Mrs.Xiao long, Mr. Hyoudou that's enough!" The Union Bully turned around to Ozpin in shock as they saw him looking at Yang with a super serious on his face.

Ozpin: "Mr Y/n, i'm sorry about what happen in the past but i want to tell you this that I'm very sorry not being there for you when you need help the most." Y/n looked at Ozpin with a very very serious look on Y/n face.

Y/n: Headmaster Ozpin, your apologies ........ I will not accepted."Union all had a shocking look on their face.

Yumi: "Y/n-kun, but-"

Y/n: "Yumi, you have no right to say anything because of you and your team along with Sona with her disappointing peerage were a part of the bully." Yumi and Sona looked down on the ground with a sad look and guilty on they face.

Saji: Oi!! Don't talk like that to her, you bastard!" Saji was about to attack Y/n before Azazel stopped Saji.

Azazel: "Mr Genshirou! What did we just talked about this?! Don't fight him" Saji flinch when he looked back at Y/n who looked at him with a death serious face.

Headmaster Hanzo is Asuka grandfather and headmaster Makarov Of the Fairy Tail class walked over to Y/n and bow down at Y/n who is still standing with a serious face.

Hanzo: "I'm very truly sorry about my granddaughter Asuka for what she and the Shinobi team have done to you, but i only beg you forgiveness and can you return back to the Union Academy?"

Y/n looked at Headmaster Hanzo and Headmaster Makarov before closing his eyes to think and then after few minute he slowly open his eyes reviewing his full red blood eyes.

The shocking thing that the Union for the first time, they saw Y/n revealing his demonic eyes. Everyone around him can feel his eyes releasing a massive evil energy aura making them shaking in fear do to the eyes too powerful for them, even Headmaster Sirzechs Lucifer, one of the four current Satan rule over underworld having a hard time to stand because of Y/n's eyes.

Y/n: "Very well, I'll Come Back... But Only With Two Conditions"

Hanzo: "Anything, Mr.

Y/n: "First, I Want a Fight Against All Of Your Best Students In Union"

And everyone shocked what Y/n just saying of his first conditions.

Glynda: "Just wait a minute, are you sure you wanna face them by yourself, Y/n?" Glynda looked at him with a shocking look on her face.

Y/n: "By Myself?... Yes... And I Just Need To Use Only This With Me"

Y/n hold his hand up and the Union saw a red-blue divice was on his hand.

Just from the look of the divice. The Union can feel the aura from the divice is very powerful just by staring at it.

Y/n: "And, My Second Condition Is If I win, I'll take Two Person Out Of Union Academy"

Y/n started to looking at the Union students making them shaking nervous.

Until two girl that he knew too well.

Asia | Koneko: "Y-Y/n-san | Y/n s-senpai, you can take us if you win."

Asia and Koneko said that making everyone shock especially Rias who in shock the most, and Ozpin with the rest of the Headmaster also nodded their head,

Ozpin: "Alright Mr Y/n. We will let..... You to have a match between you and best of the best union students to fight against you. And both miss Asia and miss Koneko will join you, if you win." Y/n nodded his.

Y/n: "Yes, I still have to finish my Union Academy graduate. But I'm not gonna kill all of them, but I will give them the worst pain that they gave me four months ago"

Arabella & Jeannie: "Of Course, my master"

Y/n: "(Nodded) Aright let return back to our mansion." Y/n then looked at his two of his pawn, and saw a blushing on their face.

Y/n: "You two can cuddle me. Once we return."

Arabella & Jeannie: "YEAHHHHHHH!!!"
