PROLOGUE SUMMONED

Morning came in one of Japan's High Schools and our beloved Hero of the Time War, Ben Tennyson, just woke up very late in class.

"*Sighing deeply.* Monday, The most present day of the week." Ben muttered to himself as he walked by the hall of this school as he had right hand on his pocket while he had a suit on his left hand and in his left pocket was the Omnitrix.

( Flashback )

Plumbers HQ.

"Benjamin, now that you graduated both Highschool and a Plumber agent we'll be sending you off to Japan as your first assignment." Grandpa Max told Ben, shocking him.

"Huh? What for Grandpa max?" Ben asked.

"We have just received reports of illegal alien activity." Magister Phillip "Phil" Billings stated.

( Note: in this story, the plumbers on earth never got shot down and Phil never went rogue and quit the plumbers to do his own fame, same with Max who never met Devlin Levin Kevin's dad in this universe. )

"Alien sightings?" Ben quire with a raised eyebrow as Max nodded.

"Yes, after hearing rumors of Vilgax being captured spread out and defeated by you, aliens began appearing again."

"But I didn't exactly do it alone." Ben told them.

"Yes you have indeed." A voice heard as they all turned to see….

"Azmuth?" Phil, Max and Ben called out as they saw The founder of the Plumbers Azmuth of the Galvin being escorted in by Magister Hulka and Patelliday.

( Note: Azmuth Looks like from Alien force. )

"Hello Young Benjamin, I have heard great things about you besides your academic skills and cadet training." Standing on Magister Hulka's shoulder he hopped on Ben's Hand as Hulka stood in front of him.

"Private Ben Tennyson is one of my Best students in the plumbers academy despite no longer having the power of the Omnitrix and is quite skilled in martial arts and weapons." Magister Hulka presents footage of him in training fluttering Ben.

"I see, however after hearing rumors of you having my prototype I would like to have it." A flash of blue light appears as Azmuth represents Benjamin the Omnitrix, the same as the one he borrowed from Teenager Ben Prime.

( AN: You can guess what it looks like. )

"Is that?" Ben asked and Azmuth grinned at him nodding.

"Yes, the Omnitrix. It took years but I perfected it." Azmuth gave it to Ben.

"Wait, you're giving this to me?" Ben asked.

"After seeing variants of you and yourself fighting other evil versions and an alternate Vilgax together on los soledad I finally found one candidate who can wield my Omnitrix."

"I…..don't….. know…. what to say." Stutter Ben.

"Just promise me one thing Tennyson, use it wisely." Azmuth soon disappeared in a flash of light as he was teleported back to Galvan Prime.

"So kiddo, ready for that Mission?" Grandpa Max asked and turned to him while grasping the Omnitrix into his hands before looking back at his grandpa with pure determination.

"Yes, grandpa, I'm ready." Ben said. "On one condition."

"Name it." Ben smiles at this.

( End of Flashback. )

Ben thinking back as he glanced at his pocket which has the Omnitrix inside sigh. 'Should I wear it now?' Ben thought.

"Hi Ben Kun." Ben was cut off from his thoughts as he turned to see. Kaori Shirasaki.

'If there's one thing I hate about being in Highschool again, it's this unavoidable situation that always gets me unwanted attention.' Ben thought.

"Good morning, Ben Kun." Smiled Kaori at him. "Sheesh you're almost late Ben Kun. Try to go to school much earlier." Ben just smiles at her awkwardly.

'Hmm, The reason I'm late again was because another alien incursion happened. That makes it the third time this week since the last four months.' Ben said. 'And since I can't really tell them my true mission here they'll either call me crazy or nonsense.'

( Flashback )

Somewhere in Japan

Ben in his plumber suit on a hot pursuit on an alien in purple armour.

( AN: Six Six looks like from The classic. )

"Stop right there aliens scumbag!" Ben ordered the alien.'This alien is known as Six six. He has been causing chaos in Japan for the last month after I took out his partner vulkanus. These two have the habit of trying to find element X or something powerful like it here on earth and sell it to the highest bidder in the galaxy. And now he found an ingredient to make it powerful.' He thought as he chased down Six six of this universe they traded blows after blows of Blaster fire Ben grazed his shoulder by blowing up his shoulder cannons causing the alien bounty Hunter to drop the stuff he took and before he could capture him Six six uses Teleporter pod to escape. "Damnit!" He cursed to himself as he look down and so the object that the criminal dropped and picked up and soon he comm plumbers Japanese branch. "This is Agent Tennyson Benjamin, I lost the target but he dropped whatever he took returning to base now."

"~{Roger that}~" Said the one operating the Teleporter pods and soon Ben was teleported back to report in.

( End of Flashback )

'So yeah that's why I'm late sleeping last night. Instead of overplaying sumo slammers like I always do back home. I was busy hunting down Six six.' Ben thought as he narrated. 'And there's one little detail. I just claimed myself to be an Otaku nerd in this school due to my love of Sumo Slammers as pretence one Hy I'm always late sleeping at night, Yeah I know, damn cover Story.' He looked back at Kaori with a soft smile. "Yeah hehe, Hi Shirasaki San good morning." He greeted her, making her smile grow larger as she blushed.

"{She's known as one of the two goddesses of this school. Now imagine yourself being in this situation with her.}"

Seeing her smiling and laughing oblivious at the glares behind her towards him.

"{I attract a lot of unwanted animosity from the students. This is one of the reasons I hate going in this school not only it'll blew my cover as an agent if anything happens but I also wish that bastard six six would show up and attack.}"

Benjamin glanced around every time he was with Kaori and due to his intense plumber training he also mastered reading feelings intentions or their expression towards him.

'Why is that loathsome American so close to Shirasaki San?!' Thought one of the male students was glaring at him.

'You're just troublesome for Shirasaki San, go back to america.'

'I can hear what they are saying from their hearts. However I'm used to this bullying thing and my training as a plumber Agent helps me hide my emotions well.' Ben thought to himself. 'After the Time War and my cadet training from the plumbers. I made a vow. Mission first, Life later.'

"Kaori, why do you even bother with that American?" A male voice said from behind me and we turned to see. Kaoki Amanogawa alongside him are his friends and the childhood friends of Kaori

Shizuku Yaegashi Ryutarou Sakagami.

"{The existence of these trio.}" Ben sigh as he wants to end this mission immediately and goes back to Bellwood.

"Good Morning, Tennyson Kun. You're cutting it a bit close like always." Shizuku smiles at him softly.

"{Shizuku Yaegashi San, she was one of these folks that almost tolerated my existence here only because she wanted their school to have a good international relations with the American if I find their school better fitting in accepting foreign transfer students and using my status as the most athletic sports academic student in Bellwood High by playing baseball and soccer gives me a little bit so-called popularity.}" Ben returned the smile at her. "{Although, the only real she might just tolerate my very existence to this school is because she's the childhood best friend of Kaori Shirasaki San, she won a kendo tournament which named her the school best swordswoman.}"

"You're so kind Kaori San." Kaoki complimented her.

"{Kaoki Amanogawa, A bit interesting person in this whole compound perfect candidate for the Japanese Plumbers branch who has the sense of Justice.}" Ben then glances at a tall Student next to Kaoki. "{Ryutarou Sakagami, his only one of your average football players in the school, his height is quite impressive; he stood around 190 cm tall. He was also Best Friend of Kaoki Amanogawa since they were kids.}"

"Forget him, there's no talking to a gutless prick." He bluntly insulted Ben, which he ignored as he just rolled his eyes.

'Only if you knew guys. Only if you knew.' Ben thought.

"Eh? I'm just talking to Tennyson Ben Kun because I wanted to." Shirasaki told her friends and Ben mentally facepalm.

'Honestly, I wanted her to just leave me alone.' Ben thought annoyed as he saw Kaoki walking towards him.

"Tennyson, when are you gonna stop fawning on Kaori she can't give attention forever." Kaoki was obviously telling to fuck off.

'You know what fuck what I think about him, his pathetic and a creep.' Ben thought as he sighed and crossed his arms. "You know Amanogawa if that's how you see it, why don't you tell her that." He told him stunning Kaoki.

"What?" Gape Kaoki is totally stunned at Ben's response.

"Look, ever since I got here and Shirasaki San became friends with a loathsome American like me, you always give me this jealous boyfriend vibe. I don't really care what you feel towards her, in fact I don't give a shit about any of you." This stunned Kaoki and those around them. "All I'm saying is I have better things to do in my life than associate with you." He told them as he went to his seat.

Shirasaki stops Kaoki to get any further in provoking Benjamin while Also hearing whispers from the other students.

'What makes me wish that an alien would show up and attack already or better yet have them be beamed up by them on a spaceship so I couldn't finish my mission here.' As if on cue a magical circle appears in the room as their teacher Aiko Hatayama.

"The hell?!" Exclaimed Ryutarou in confusion.

"What's going on?!" Asked Kaoki worriedly.

'Wait this could be my chance!' Ben thought as he snatched his suitcase and pulled out his Plumber badge which has his nanotech plumber suit to put it on his chest as the armour appears around him. 'Wait hold on a second this is not the effect of some kind of teleporter pod or Tractor beam, it's a magical circle that I saw in some anime and Games!'

"It's spreading all over the classroom!" Exclaimed Shirasaki.

"Everyone leaves the classroom at once!" Yaegashi San warned everyone but it was too late as bright light consumed them and they soon found themselves in some kind of Palace.

"What the hell?!"
