Before starting this story, I will clarify from which part it will start from one and the other anime, Goku will meet Momoyo early in this story for reasons unknown. I won't be introducing sagas due to the fact that I like to keep things simple, and easier to understand instead of using planet buster Goku, I will be doing my own twist into these two worlds into one universe. I take inspiration from KidGokuSupremo, seeing that I was reading his story recently, I decided to write another Dragon Ball fanfic. Please give all credits to him and inspire me to continue writing Dragon Ball.

I don't own Dragon Ball or Maji de Watashi ni Koishinasai, they belonged to their respective creators Akira Toriyama and Minato Soft, respectively.

One morning in the bright afternoon, we see a young boy possessing spiky wild black hairstyle, dark-colored eyes, and facial features. He wears a turquoise gi with a white knot-style obi, orange wristbands, dark green pants, and black kung fu shoes with orange stockings. (End of Z Outfit) Brown tail wrapped around his waist like a belt, and his Power Pole sheathed inside its scabbard with white rope tied up behind his back. This is Son Goku!

Goku lived in the mountains in Mount Paozu, his Grandpa Gohan found and raised him into a powerful fighter, even though his grandpa died from the Ape Monster, he can take care of himself from monsters lurking near his home. He also prays to the four star Dragon Ball since he saw his grandpa praying to it, so he decides to do the same and pray as well, since he originally believes his grandpa's soul was within the ball itself. However, things changed when he met his first human encounter, Bulma.

The two of them went into lots of epic adventures trying to find the seven Dragon Balls, they met new friends, enemies, and lots of interesting things he didn't know existed. He then met Master Roshi, the master who taught his grandpa about everything in martial arts, after clearing out the Ox-King's castle and thus learning the Kamehameha from Roshi, he was given a rare opportunity to become Roshi's pupil.

Time went by and Goku meet Krillin, the two of them became best friends when spending time training together with Master Roshi. In the 21st World Martial Arts Tournament, Goku was defeated by an amazing opponent Jackie Chun, and can't wait to face Jackie in the next tournament. Roshi then talk to the Goku that he's no longer his student, because Goku is too advance and already surpass his expectations, if Goku wants to get stronger he needs to expand his mind and gain experience from the world. Goku understands and he'll travel the world and meet up with everyone at the next tournament in two years.

Before he leaves however, Master Roshi mentions another teacher that might take him in.

"Listen to me, Goku, across the other side of this world there is a city called Kawakami City. I have an old contact with a fellow martial artist named Tesshin Kawakami, he's an old friend and grandmaster of the Kawakami Temple, if you somehow found yourself there let ol' Kawakami know if you're planning to visit there. I'm sure he won't mind teaching you a few things or two." Master Roshi said to Goku

"Is he powerful like you, master?" Goku tilted his head a bit, wondering if this Tesshin is in the same league as his master.

"He is, the two of us met each other and went to the same school together. I hadn't seen him since the death of our former master, Master Mutaito, but we still keep in touch from time to time. Last I heard he started an academy in that place." Roshi looks up at the blue sky and remembers the old days with Tesshin.

"Gosh~ Well, I'll take your advice and head there when I'm done packing up my things, thank you for teaching me, master!" Goku smiles at her former master, Roshi then patted Goku's head sort of like father and son.

"Don't mention it, kid, you still have a long way to go if you plan to reach my level. Also before you leave, last I heard from Tesshin is him having a granddaughter and is training her as we speak, she's perhaps four years older than you. And perhaps even stronger than you." said Roshi to Goku.

"Really?! wow, I can't wait to fight against her!" Goku was getting excited and couldn't wait to face the granddaughter of his master's friend.

"Careful Goku, you don't want overconfidence to be your downfall. It's fine being excited but if I know Tesshin, he trained his granddaughter seriously or perhaps asks his pupils to do it. But make no mistake, Goku, there are stronger foes out there and will defeat you if you're not careful." Roshi gives one last lesson to his former pupil, and Goku listens to him with a nod.

"Got it. I'll be careful, Master."

Goku was riding the nimbus cloud and continued his journey to find Kawakami City. He wasn't good at directions so before he left he visited Bulma first, she was surprised that he was going all the way towards the other side of the earth but nonetheless, gave him a map and directions to find Kawakami City. He thanked Bulma and can't wait to see her again in the next two years.

"Hmm... what should I do if I find this place? I want to face the granddaughter of my master's friend, but at the same time wonder what should I do when I get there." Goku said within his mind, once he gets to Kawakami City then what? He could train and hone his skills and also explore the area, but at the same time his lack of education leaves his brain empty headed sometimes.

"Oh whatever, once I reach this temple and meet Master Tesshin, I'll challenge his granddaughter to a fight!" Goku chuckles before relaxing on his cloud, he was getting excited and couldn't wait to find out what's next.

Kawakami Temple

Tesshin Kawakami receives unexpected news from his long-time friend Roshi; it seems his former pupil is coming to his temple as he speaks. This is highly usual but not the worst since he remembers the time when he and Roshi, spying on women's bathhouses with nosebleeds and being chased out from throwing objects, those were the days...

He was sitting outside on his porch waiting for Roshi's pupil to come. He was rather curious to see if this pupil, if Roshi, has what it takes to face his granddaughter in a match. Roshi explains that his pupil, Goku, wishes to face his granddaughter Momoyo once he comes to Kawakami City. His granddaughter isn't anyone that should be messed with due to her incredible power, but he has to see if Goku can somehow rival Momoyo.

"Hey, Jiji, you mention you have something to talk to me about?" Momoyo arrives at the temple, she's just finished school and playing with her friends, she receives a call from her grandfather something very important.

"Yes, Momoyo. Last night I received a call from an old friend of mine. He's the master of the turtle-hermit style, and lives on the other side of the world. He wrote me a message saying how he's former pupil will be coming here to face you in a fight." Tesshin said to his granddaughter, saying the girl was grinning at the challenge.

"Really? I hope your old friend's pupil can prove themselves worthy of challenging me. The people around here are just too weak all of the sudden, including those transferring here to attend the academy aren't a challenge to me. Besides the Big Four, there is no one around here that is on my level." Momoyo sighs and wishes there was someone out there that is in her level and league.

Momoyo has a great love for fighting and for just having fun in general. Her love for fighting however, has proven to be outlined since she is so skilled in martial arts, she constantly defeats her opponents without exertion and real effort, which leads to her frustrations. Winning a fight that makes her use her full effort though, will always put her in a good mood and make her more relaxed afterwards.

"I'm sure that Roshi's pupil will prove a challenge to you. Since he was trained by my friend Roshi, I have no doubts that this boy you'll be facing soon, will perhaps be the challenge you've been looking for all these years." Tesshin stroked his white beard and was looking forward to this match.

"Hoh~ Don't make my blood boil there Jiji, since I'm getting excited and you know how I enjoy a good fight." Momoyo smirks with confidence and couldn't wait to fight her newest opponent...

Suddenly a loud whispering noise coming above them, they see a yellow cloud riding towards the temple, Momo was in awe seeing that she has never seen a yellow cloud before nonetheless flying. Until she sees a young boy in blue gi, jumping downwards and lands into the temple itself. The boy stood and with a smile on his face.

"Are you Master Tesshin? Master Roshi says you can teach me a thing or two." Goku calmly said while looking at Momo, he can feel the powerful energy coming from this girl, so this must be the Master Tesshin's granddaughter.

"Yes, I am Tesshin Kawakami, and this beside me is Momoyo Kawakami, my granddaughter." Tesshin introduces both him and Momo to the young warrior, he'll admit that he was surprised how young Goku was, if has to guess he's perhaps two years younger than Momo herself.

Momo was staring at Goku with a huge interest, she can feel the generating powers coming from the boy, it's almost similar to hers but weak at the same time. Still... she was getting a feeling on not underestimating this boy, seeing how well-trained and physical his body looks. Making her blood boil in excitement.

Tesshin already sees the tensions coming from both fighters, he coughs his hand gaining their attention, "I think it would be best if we... go somewhere proper for this fight taking place."

"Sounds good to me, I can't wait to face you, Momo." Goku grins at Momo, who returns the gesture. It seems this fight will be interesting after all...

Goku and Momo stare at each other with confident grins across their faces, both wanting to test each other's powers and see who's the powerful fighter among them.

Yamato Naoe was visiting the Kawakami Temple to find his Nee-san, she left in a hurry saying family emergency and he wondered if something happened at the temple. So his friends tagged along with him since they all were also worried for Nee-san as well.

"I wonder what's going on with Onee-sama, she usually brings me with her for this sort of thing." Kazuko spoke with worriedness in her tone.

"I'm sure she'll be fine, besides it must be something important happening in the temple." Gakuto reassures Kazuko and just waves it off, something important Momoyo has to do.

"Still... it's unlike Momoyo, leaving in such a hurry unless it's very serious." Takuya still questions the sudden leave from Momo.

"Guys! It's just like Gakuto said, she's perhaps fine and we'll check up on her if things are okay!" Shouichi also reassures everyone with his weird aura that calms them down...

Yamato however was thinking deeply and still calculating numbers within his mind, the self-proclaimed genius of 2-F, he knows his Nee-san better than anyone in the group. So it bothers him as to what's going on within the temple right now...

"How Yamato, after we are done finding out what's wrong with Momoyo, do you want to hang out with me~" Miyako is still trying her best to get into Yamato's junk.

"No, Miyako... I'm just calculating and reasoning as to why Nee-san left." Yamato sighs while scratching behind his head.

Christiane Friedrich is still adjusting her place within the group, while she hasn't known Momoyo long like the rest, she couldn't help wondering what's going on within the mind of that brute woman.

Yukie Mayuzumi, who is also the newest member of the Kazuma Family, kept to herself while helping the others to find Momoyo.

When the group was getting closer to the temple, they could hear loud sounds of fighting coming from there. They sprint towards where they have heard the noise, something must have happened at the temple and where Momo is at right now. Yamato is filled with worries within his heart and hopes that his Nee-san is okay in the aftermath, but knowing her... it's perhaps the opposite.

They found the noise and in turn shocked and surprised them all. There was Momoyo with a grin on her face, she was taken serious damage from her face and throughout her clothes, that's when they see her opponent with blue gi in similar damage, it was a boy younger than them and somehow he's able to not only keeping up with Momoyo, but actually landed quite decent hits on the undefeated woman.

"Yo~ Yamato, I see you brought the whole crew with you." Momoyo greeted her friends during her battle.

"Onee-sama!" Kazuko was worried for her older sister and was about to rush to help her, but Gakuto grabbed a hold of her and told her to calm down. "This is Momo's fight, we shouldn't interfere unless we have to."

Momo turns back at her opponent and to her surprise found him gone, only when Goku reappears in front of her and tries to land a kick, she blocks the kick and sends a powerful punch towards Goku's abdomen, but to her surprise again her kick flies through Goku, and thus there was now ten Goku's surrounding her. She grins and knows this technique afterimage, an ability to move so swiftly that an image of the user is left behind.

"Nice technique there Goku, but even you can't beat me if you hide behind these fakes! Kawakami Style: Ultimate Right Crusher!" Momoyo uses both her arms to rapid fire this technique. This technique is useful on blowing away clones of enemies, the afterimages of Goku faded away, but she noticed he wasn't in the hidden group... until she turns her right and a kick delivered with force knocks her away from Goku.

Goku continues with his offensive approach and trying to gain the upper hand against Momo, however said girl wasn't keen on herself being pushed back by anyone. She glares at Goku, now looking serious and rushes towards him.

"Daaaaaaaaa!" Goku yells as he tries to punch Momo with his right.

"Haaaaaaaaa!" Momoyo yells as she tries to punch Goku with her right.

"Dadadadada!" Goku sending punch and kicks towards Momo.

"Hiahiahiahia!" Momoyo sending her own punch and kicks towards Goku.

The fight between them was very even between the two, neither of them wanted to give up when they both trained so hard to reach the level they are in, the two warriors almost seemingly have the same powers. Finally Momo lands an uppercut on Goku's jaw sending him flying mid-air, she jumps up and gaining momentum and thus with both hands behind her head, she tries to land a powerful double axe-handle on Goku, but he dodge the upcoming attack and the two of them are somehow fighting in mid-air and falling at the same time.

"Daaaaaaaa!" Goku again charges after Momo with intense speed.

"Haaaaaaaa!" Momoyo follows suit and copies Goku to gain the upper hand.

They both stuck their foreheads with each other and using their own heads and tried to make the other one give, Goku gritted his teeth with a frown while Momo was having similar issues but smiled since she hadn't been in an actual fight in a long time! The two of them are still fighting in mid-air sending powerful waves after waves flying all over the temple, till they reach the ground and still battling each other, cracks below them are causing slight tremors in the place. In fact almost throughout the city you can feel the fight happening in the temple, as many people were screaming out what's going on, however most of the powerful fighters in the area knew it was Momo battling against someone strong...

The Spectators watching the fight going down...

"This is insane!" Yamato couldn't believe there was someone that can match his nee-san like this!

"Come on, Onee-sama!" Kazuko cheers for her older sister.

"Dude, I'm sending this on the internet, this fight is freaking wicked!" Gakuto opens his phone and starts recording live on the internet, he's going to receive lots of money for this...

"I-I can't feel my legs..." Takuya tries to stand on his feet to no avail since the ground is shaking too much.

"How can someone rival this much power against Momoyo." Miyako spoke seriously for once, for all she has known about Momoyo is that she was undefeatable... Can that boy she's fighting take that title?

Shouich didn't say anything and just watched the fight with a smile across his face, this is way better than action movies!

"H-how could the ground keep on shaking like this?!" Christiane is also struggling to keep up on her feet during this chaos!

Yukie kept her head down during this match, while praying that nothing serious will happen soon...

People watching it from live recording...

Ageha Kuki was watching the live video during her break time in the Kuki Corporation, she is surprised to see Momoyo is actually giving her all against this mysterious young fighter. She fought against Momoyo in the past and thus are rivals, but she has never seen said rival more excited on facing her newest challenge.

"Sugoi... Miss Momoyo, is facing off a boy who seemingly have the same powers like hers." Kojurou Takeda watching the battle transpire on the live event.

"This boy... Kojurou, give me any information about Kawakami Momoyo's opponent, I need information on how he's able to keep up with Momoyo." Ageha said to her manservant, who saluted and left the room to find any piece of information about the mysterious opponent.

Tatsuko Itagaki was watching the live video on her phone, she was feeling bored and wasn't cooking anything so she searched online for anything interesting. This caught her attention and soon enough her family came in to watch the fight with her.

"Woah! Now this is what I call a fight!" Ryuhei Itagaki grins while watching this fight transpire.

"How is it possible that a boy is able to match Momoyo Kawakami's powers?" Ami Itagaki mutters trying to figure out the possibility of the boy's powers...

"Hah! I think I can see that busty bitch feeling fatigue! that brat is actually keeping up the pressure on her!" Angel Itagaki smirked while seeing that Momoyo was going to lose.

However an old mentor and former associate of the Kawakami Temple, Gyobu Shakadou, also watched the fight transpire. He admits that he was impressed that Momoyo is being manhandled by the boy she's facing, in fact he can't remember the last time someone managed to push his former student this far.

He grins and goes to the kitchen to make something, "This day just keeps getting better and better..."

Back to the fight...

Goku and Momoyo were away from each other from a long distance catching a breathing room. Goku has to admit that Momoyo's power is incredible, in fact it seems to be growing and growing throughout this fight! He needs to keep some of his energy intact, plus planning to defeat Momo's crazy powerful force if he's going to stand a chance against her.

Momoyo looked at Goku and felt her blood pumping even further. No one has managed to push her this far besides the Big Four, her gramps was right when this boy could be the challenge she has been looking for, fighters from all over the world would challenge her to achieve fame but short lived. She effortlessly defeats them all too easily and gets frustrated, however the person in front of her is not only able to keep up with her, but is giving his all in this fight... she likes that.

"Son Goku!, I Momoyo Kawakami, acknowledge you as a man!. No single man could ever push me this far, the rest I fought were easily defeated and leaving me disappointed. You however, show great promise and are able to keep up with me, one of the members of the Big Four of the North. But I hope that isn't everything you got in this battle, because I haven't gone serious yet." Momoyo said to Goku.

Goku gives her a warm smile but keeps his fighting stance up, "I can say the same to you, I haven't felt a fight like this in a long time. I'm getting excited just fighting you."

Both fighters look at each other with smiles, before dropping them completely when Momoyo begins to charge at Goku again. Both begin striking different blows, Goku on the offensive gives a series of rapid punches that Momoyo blocks with ease, she grabs a hold of Goku's tunic and throws him across the battlefield, Goku regains control and jumps above Momoyo with his power pole.

"Power Pole! Extend!" Goku yells while his red pole begins to extend itself to hit Momo, she dodges to the side while avoiding Goku's flying kick near her face, Goku continues with the offensive approach while trying to hit Momoyo with his staff. Momoyo grabs hold of the staff trying to break it away from Goku, fortunately Goku has more experience with his own weapon in turn sliding underneath Momoyo's legs, while sending a dropkick onto her back. Momo gritted her teeth on feeling the pain but caught a hold on Goku's body, she threw him onto the hard ground and tried to deliver an elbow drop on him. Goku dodges the upcoming attack and sends a spinning kick onto Momo's face, sending her flying in the air away from him.

However Goku felt two hands grab a hold onto his legs, he turned and saw Momoyo somehow behind him, while she turned him upside down for her to land one of her technique moves.

"Kawakami Driver!" Momoyo shouts her attack move, holding onto Goku's legs while his shoulders being locked onto hers, she has done this move before against her opponents, mostly females. But if she used this move onto a man... well, let's just say it will be unpleasant on the crotch area. Before slamming this move onto the ground.

"GAAAAAAAAH!" Goku screams as he feels his lower region feeling intense pain.

Momo however wasn't done yet as she switched her arms from Goku's legs to his waist area, before jumping upwards to land the finishing blow.

"Kawakami Style: Ultimate Spinning German Suplex!" She yells before spinning like a cyclone, until it connects onto the ground once again, Goku felt the bones behind his back were being broken, as he coughs out blood coming out of his mouth.

"BUARGH!" Says Goku before Momo jumps away from him, he gritted his teeth and couldn't stand due to his lower region... but by some miracle he found the strength to get up, surprising and impressing Momoyo.

"How? No one could survive one or two of my moves... what is he?" Momoyo lingering in her thoughts.

Goku stood up shaking but still alive. He underestimates how strong Momoyo truly is, she's has more experience than him in any situation, but... that also makes him want to improve even more, he never knew there was someone this strong out here.

"You can break my body, my spirit, or leave me broken. But... I'll come back stronger, stronger than I ever was and will surpass you!" Goku regains control of his body ignoring the pain he's feeling right now.

Goku went back to his turtle-style stance, while Momoyo did the same with the Kawakami stance. She charges in to finish this fight but only for her attacks going through the boy, her eyes bugged out when she felt a punch hitting her stomach, she looked down to see Goku before sending a kick on her jaw. She coughs out blood while feeling a bit air-headed before dropping onto the cold ground.

The Spectators...

"W-what... was that?!" Kazuko shouted out loud that nearly everyone in the whole neighborhood could hear her.

"Afterimage... It's a technique performed to those who are quick on their feet, meaning they can move very fast and leave their opponent confused and wide-open." Yamato studies with the Kawakami Temple because of her Nee-san, while he can't do this move he knows enough that only those with speed higher than he has, can use this to their advantage.

"Sugoi..." Gakuto mutters and never knew that martial arts could use those speed things...

Back to the fight...

Momo wiped the blood from her mouth and stood up, her clothes were getting dirty but she didn't care at the moment. At last it seems the gods have finally heard her calling on sending a worthy challenger, to think Son Goku could not only damage her further but actually survive her two most famous attacks. She wants to know more about Son Goku, and how much further he could handle against her.

Goku not feeling better himself as his clothes were torn and bloody a bit. He fought several other opponents but none of them even come close to the person he's staring at right now. His wee-wee was getting better and he can focus more on Momo, however he still needs to watch out for her devastating attack moves...

"Son Goku! I already explained this already but you are the first one to push me this far! No man could have ever achieved this by leaving me in this state!" Momoyo grins while explaining it again to Goku.

"But... Let's see how you can handle... THIS?!" She begins to charge up all of her Ki into this one attack move...

Goku felt a tremendous Ki and aura appearing over Momoyo, it seems she was charging up some energy blasts or something. He felt sweat appearing on his forehead and knew he had to use that technique that he learned from Master Roshi.

Goku slid his right foot to the back and crouch, preparing himself in a stance. Both hands formed claws that faced each other horizontally as he pulled it behind. He channels his Ki as it softly bursts around him. Bluish white aura begins to appear above Goku.

"Is that...?" Tesshin was watching at the sidelines and away from the battlefield, he could step in to stop the match... but he wants to see how this will transpire. His assistant Lu Yi also watches the match with discomfort, he wishes to stop the match from destroying the sacred temple, but his master stops him and awaits how this will go.

"Kaa..." Goku started to chant, his surroundings were spiraled with sand as if he was a tornado. "Mee..." A distinguished sound can be heard, it was akin to a lumpy and flashing sound of energy accumulating. "Haa..." A glowing ball in the color of light blue appeared in Goku's palm, it seemed gentle and yet volatile. "Mee..." The ball shines brighter as it sends out beams of light passing through the small gaps of his fingers.

The sky had darkened and the ball of energy accumulating in between palms began to get larger in size as Goku cups it in order to keep it in control.

"Kawakami Style..." Momoyo's was energizing the yellow aura around her, she never thought she had to use this move against her toughest challenge yet. But, she can see that Goku's beam is almost similar to hers... she wants to test it out and see which beam is stronger!

This is it.

The ultimate showdown between which beams is the strongest.

Between two of the strongest fighters in their respective parts on Earth.

Will it be Momoyo Kawakami, granddaughter of Tesshin Kawakami, Big Four of the North, and strongest woman on earth. Or will it be Son Goku, grandson of Son Gohan, former pupil of Master Roshi, and one day becoming the savior of earth.

"STAR DESTROYER!"

"HAAAAAAAAAAAAA!"

I'll leave here for now folks, sorry for the disappointment but you'll have to find out next time~
