Goku and Akeno walked to school holding each other's hand and it was still new for them since they didn't look at each other but looked slightly embarrassed. Akeno never really had a boyfriend so she was completely new at this. Goku was the same since this was his first girlfriend (that he knows of)

Asia - Goku! Akeno!

They turned around to see Asia, Koneko, Minako, Issei and Xenovia walking towards them.

Goku - Yo guys.

Akeno - Good morning everyone. I take it Rias went to go show her brother around town.

Issei - Yeah.

Suddenly he dropped his book bag and grabbed his left arm in pain.

Issei - What the hell?

Goku sensed it and he looked towards the direction the energy was coming from and Broly was nearby it.

Goku - Come on everyone let's head there. Broly is close by and it can't be good.

They all ran there and when reached there they saw Broly glaring at a man with white hair and blue eyes.

Goku - Broly stand down for now.

Broly - I'm not stupid. I know we can't fight here.

Vali - Greetings everyone I am the Vanishing Dragon also known as the White Dragon Emperor Vali. It's good to meet you again Issei. Don't worry I'm not here to fight but with advice. I noticed your balance breaker is pretty pathetic and if you aren't nurture and well taken care of you'll die quick. So I'm telling you this too Rias!

Everyone turned around to see Kiba and Rias there behind them glaring at Vali.

Rias - I don't need your advice.

Vali - Your right. Now that you have two Saiyans that can help you, I guess you don't. I have much more important things to do today.

Goku - Be lucky we didn't have to fight.

Vali - Like you can beat me. The big guy took a few minutes to beat Kokabiel. I would beat him with just one hit.

Goku's eyes went silver and he released a giant wave of energy even surprising Vali.

Vali - This power intrigues me. Maybe you'll be better than the Red Dragon.

Goku powered down as Vali left the school grounds and Rias and Akeno held Goku's hand scared of what could have happened.

Everyone then went to school with still a little worry but the school events were able to take their mind off it.

Goku and Broly continued being the best at every sport and exercise. Minako saw Goku taking off his shirt and blushed so hard she could be mistaken for a tomato. But deep down she really liked Goku.

After the day ended everyone went back home as Goku started cooking dinner and everyone helped him set up dinner except Broly who went to the store to buy dessert.

??? - Do you mind if we help?

Goku turned around to see Minako and Xenovia with an apron on. He smiled and all three of them started cooking dinner. Asia and Issei opened the door and see they were almost done so he went to help them and Asia went to help Goku and the other girls cook. Soon everyone would be done with dinner and Broly returned with a cake as everyone sat down and then the door opened to reveal a late Kiba and Koneko.

Goku - I was dragging this out for you both to arrive.

Kiba - Sorry for the tardiness.

Everyone then started to eat and talk about either school or even just make jokes. Soon after the dinner was done and everyone cleaned up, Goku went to bed and felt something. He lifted his covers and saw Akeno on top of him and he even saw Rias getting on the bed with a night gown.

Rias - Hello Goku~

Goku normally wouldn't mind but he saw that it was a see through gown. He blushed and he saw Akeno take off her bra and he was just being forced in her chest with both arguing and he passed out but someone else took control.

"Lay down now"

Akeno and Rias looked towards Goku as he stood up and went to the door as he opened it and saw Xenovia and Minako about to knock as he grabbed them and pulled them in the room.

Minako - Goku..wait.

He pushed them all to the bed and he went to the door and locked it as the room started to get hot.

Goku - Remember you all wanted this. Now it's time you all get punished.

The room suddenly got really hot and everyone saw Goku rip off his shirt as he opened his eyes and they were silver. His tone was different and the girls blushed immensely as they didn't expect Goku to change attitude quickly. He was someone else.

Rias - G-Goku are you-

Kakarot - My name is Kakarot.

Instantly moved towards Akeno as he pushed her down and he smacked her butt twice and Akeno moaned.

Kakarot - Now I never said I was a nice guy like him.

Akeno - G-gok-mmmph

Kakarot cut her off by kissing her and it was a passionate kiss with him touching her breast and he held her neck stopping the kiss.

Kakarot - The next words are "Yes sir" or have you forgotten?

Akeno - Yes sir.

Kakarot - Now all of you lay down because the night is young.

He released more heat and all 4 girls got the most pleasurable night of their life with Rias, Xenovia and Minako happy their first time was with Goku but Akeno knew this wasn't Goku. It was someone who was Goku but with more dominance.

(The next morning)

Goku woke up and moved to his left to see a pair of breast in front of him as he moved his head to see it was Akeno as he smiled and kissed her neck and cheek causing her to wake up.

Akeno - Morning you beast~

Goku - I see someone wants a little morning workout.

Akeno - After last night I think you might break me again.

Goku - Last night?

Akeno pointed to her left and Goku looked at the direction to see Rias, Xenovia and Minako asleep and Goku laid down on the bed confused on what happened last night?

Akeno - So master...do you still wanna be called Kakarot?

Goku - Oh my god.

He got out of bed and went to shower as he tried to remember what happened. The girls on the other hand were still blushing on what happened but they agreed that it was someone else in Goku's conscience.

Akeno - Just remember I'm the main girl but I don't mind sharing after what happened last night, I doubt I would have survived.

Goku walked out and the girls left with Akeno giving Goku a kiss and he was still just as confused.

They all went to school and it was open house as Issei's parents arrived with Sirzechs and his assistant were with him however for Goku he was the center of attention with Broly. Both were killing every sport everyone was recording and eventually all the females surrounded them when it was time for the annual marathon with both Goku and Broly as the main contestants. Akeno, Rias and Xenovia were front row with Minako, Koneko and Asia behind them sitting in the top chairs seeing both boys stretching.

Coach - Ready?!

Both got in running position as the coach shot the gun and instantly both ran at full speed (which is very small amount of speed but believable.)

Goku - You won't win.

Broly - Like I'll let you!

After a few minutes the winner was actually both as they tied and Goku was disappointed but excited for the next race. Broly on the other hand was angry that he tied with Goku but he couldn't lie that he wasn't excited for the next competition. 

After the competition, Goku was slightly choking Issei as he saw that he wanted to make a statue of Akeno and he was jealous that he made a sculpture of Rias naked. He held him in a head lock and letting him go when he grabbed the sculpture and destroyed it. 

Goku - Look she is also my woman now so watch yourself.

However students ran to the gym and this confused the group but Rias and Akeno knew who it was. Issei knew the cosplay and Saji kicked out all the other students away and Sona entered the gym.

Goku felt the similarities between her and Sona but Rias answered his mystery. 

Rias - That is Lady Serafall Leviathan. 

Goku smiled seeing how opposite she was by attitude than Sona. Broly walked in eating a meatbun and he saw Leviathan. 

Broly - Who's the brat?

Leviathan - Who said tha-.....

Leviathan looked at Broly who still had his shirt unbuttoned since he was still sweaty from being outside. She blushed but she also remembered the look of his face and she recognized him.

Leviathan - So who is this hunk of a man?

Goku - That is Broly. He's a Saiyan just like me, your highness.

She turned to Goku and she instantly ran to him and asked to see his power. 

Goku - Hmmm. Since there is no one here or around the area...why not? 

Everyone backed away and Goku transformed into a Super Saiyan 2 and Leviathan was amazed of the power.

Goku - This is the power I just acquired. Broly has a form that can match this in power.

Leviathan - Really? Please show me. 

Broly - Why do I have to?! Plus I'm not gonna buy another uniform since I don't even understand size here on this planet!

Goku - Don't worry Shenron can just create a new one and I don't know how much stronger you've gotten. 

Broly - (groans) fine. 

Goku - Shenron create a barrier around the gym so no one sees or feels his power. 

The barrier was created and Broly once again transformed into his Legendary state.

 Leviathan was inspecting Broly but mostly his muscles and he powered down since he was embarrassed when Leviathan started touching him. Sona then started to lecture her by telling her that she had to change her outfit. 

Goku - You know it's funny how they are acting in reverse roles. But it's cute. 

Issei - Yeah but don't you think if Sona mentioned her earlier she would have showed up to the battle with Kokabiel. You think she would have needed her help or is it because they don't get along? 

Akeno - Actually it's the opposite. Lady Leviathan loves her sister so much some would say she's obsessed and if she did help it would have started a war of her own.

Sona cried and ran out of the gym with Saji and Leviathan going after her. Rias on the other hand felt nervous because she knew she could relate with her embarrassment. They regrouped with the others and they met up with Issei's parents but the most shocking was Rias' father.

The adults agreed to meet together at Issei's house and Goku felt slightly left out since his dad was still not home. 

Goku - Say Shenron how's my dad doing? 

Shenron - From what I can see...He's perfectly fine sleeping in a hotel.

Goku - That's good to know. 

After arriving to the house, both families started to drink and showed the videos of they're kids but Goku was happy that they were getting along. However Rias got really embarrassed and ran to the other room with Goku deciding to go after her. 

Goku - Hey Rias...do you wanna talk?
