This Summer..... 

( We see the Planeptune Basilicom first..) 

 Neptune: Hello? Noire? Taiga? Blanc? Hiiro? Vert? Kiriya? Emu-kun? Neptune, Emu and friends' summer vacation is getting.... 

 Neptune: Since summer vacation is ending, we've gotta go somewhere together! 

 (Then, we see Emu and Parado wearing their bags. Each boys are beside to their perspective l- I mean beside to Nepgear and Neptune.) 

 (Me: *deadpans* Geez, you almost screwed it up, Fourze....) 

 (RF2: Yeah, yeah, I know. *AHEM* Now then, where were we..... oh right. Neptune, however, is wearing a sunhat as well. Then, behind the Planeptune 4 are the rest of the Goddesses, Candidates and Riders, along with Kuroto-Shin and Poppy.... Oh and also Nico.) 

 Histoire: Neptune-san! 

 A COMPLETELY NEW COMEBACK!

 IF: Leave it up to me! (And Compa and IF are beside the car waiting for Neptune and the other Planeptune 4) 

 Compa: I'm coming along, desu! (Suddenly, Parado is controlling a droid that he recently bought, recording the beautiful wonders in this vacation mountain of Lastation, and Emu recording Noire and Uni explaining about the vacation mountain.) 

 Uni: This amazing view is Lastation's Pride. It's my vacation house. The CPUs and Riders are spending their vacation at "my vacation mountain". 

 Ram: It's a lot of fun here! 

 Rom: Very beautiful! (Then, Noire was on the camera, being recorded by Emu, is still explaining, Rom and Ram are chasing after a butterfly in the background while the Tsun-Tsun Goddess is explaining. And afterwards, Emu, Neptune, and the twins, who're in their swimsuits (thankfully not revealing) are playing at the water.) 

 Vert: This is the new 4 Goddesses Online. Along with a special DLC, which are the Riders.

(Then Vert shows the gang the newly released of 4 Goddesses Online. Then Neptune began to raise up her.... Uhhhh.... a purple themed game console onto the air as Emu is beside her doing the same to his friend. Blanc is beside her, who's sitting at the table reading a book, with Hiiro beside the hot-headed kuudere, who's also eating a strawberry themed cake. Then to the other side is Vert and Kiriya. Vert is just looking to Neptune and Kiriya is doing nothing but to fix his shades. Behind the Leanbox Duo is our Tsundere Goddess, Noire and her Rider Guardian, Taiga. Noire is fishing and Taiga is doing more target practices to a bullseye mark.) 

 Neptune: Let's do a eight player battle! Blanc and Hiiro: Whenever, wherever, with whomever. 

Blanc: Lowee shall rise up. (As Blanc and Hiiro said that in unison, they took out their same colored scheme consoles, which is light blue.) (And out of nowhere, Noire was recorded by Parado as she is now seen wearing a maid costume with a tong in her hands.) 

 Noire: We're having a barbecue! (Then Taiga, who stopped doing target practices, and Uni are handing Noire the delicous soon-to-be cooked meals and Noire begans to cook 'em up. Nepgear and Parado are just looking to the three. Well, mostly Nepgear since she's admiring on how Uni and Noire are doing fine as siblings, compared to herself and Neptune's.) 

 Noire: Uni, Taiga are the foods ready? Nepgear: 'I wonder when me and Onee-chan will get along? Like dearest sisters.' Nepgear is hoping for a [future] with her sister from now on.... (Then, we see Nepgear, Parado, Emu and the other Candidates are entering a good old fashion ancient Japanese gate entrance.) 

 Emu: Nepgear, what're we doing here? (The three began to hear something as they turned around...... and followed on pursuit of Adult Neptune kicking a HUGE bug. This amazes Nepgear when she saw Adult Neptune.) 

 Adult Neptune: Are you guys okay? My name's Neptune. Leave it to your older/younger sister!

(The Adult Neptune lands safely and turns around to the six as we see Emu gasped in shock and Parado feeling that he has a headache when they saw Adult Neptune.) 

 Emu: N-N-Neps?! 

 Parado: Oh great, another headache.... (Then we see Nepgear, Emu and Parado having a discussion with Adult Neptune.)

 Nepgear: 'This sister is from another diemsnion without CPUs or Rider Guardians.' Another sister suddenly appears. (Dimension Tripper Neptune) (Nepgear is in front of Adult Neptune, who's about to start her bonfire with the help of Parado and Emu.) 

 Nepgear: My dream has come true. I'm glad I met Neptune-san. 

 Adult Neptune: I'm also glad I also met you, Nepgear. (Then, they're, only Adult Neptune and Nepgear, inside the tent, about to sleep only in their underwear...? Was it?)

(Me:-_- Just continue.) 

 Parado: I'm glad that she isn't a headache. 

 Emu: Is that really necessary? (And Emu and Parado are sleeping outside.) 

 Nepgear: Goodnight, guys. Adult Neptune, Parado and Emu: Sleep well, Nepgear/G'night, Gears/ Night Night, Nepgear. 

 Nepgear: Onee-chan! 

 Emu: Neps! 

 Parado: Oi! Airhead! 

 Neptune: Guys, I'm sorry..... 

 (The scene changed as we see Neptune, who's laying down on the couch and not feeling well, as her hand was being held by Nepgear and Neptune herself was being companied by Emu and Parado behind her.)

Nepgear: If I get re;born, I'll be a better sister.... 

Saying farewell to her beloved sister.....?! (Neptune)

 (Other clips began to play, like the Planeptune Crew on their way to the mountain. Blanc and Hiiro smiling and looking to each other. Noire grinning as she took out a cooked Eggplant, which made Kiriya laugh. Vert fangirling. Neptune eating a red dessert, which made her excited. Emu fighting Parado in another round of Smash Bros. Ultimate. Croire appearing and floating in front of Adult Nep. Adult Neptune aiming a gun. And the CPU, Riders and Candidates, except for the Planeptune Four, transforming and the CPUs and Riders doing their perspective move sets. Emu and Parado doing a brofist to each to each other as Parado was absorb onto Emu and Emu himself smirking while taking out the Knockout Fighter 2 Gashat, making him transform into Ex-aid Double Fighter Level 39. With Parado appearing beside Emu as Para-DX Level 39. Neptune and Nepgear holding their hands to each other, closing their eyes, as they changed into their HDD forms and phasing onto each other (not sexually, you guys) which also changed their appearance.)

Purple Heart (Neptune): Guys, let's go. (As Purple Heart said that, a quick image of her new form flashed. Same goes for Nepgear.) 

 Ex-aid/Para-DX/Purple Sister: Hai, let's do this!/You got it!/Yes, Onee-chan! Purple Sister: We'll show you! (Purple Sister aimed her weapon as it began to charge a rainbowic aura around the weapon.) 

 Purple Heart: The power of the CPUs! (Purple Heart also aimed her weapon and it also began to charge a rainbowic aura as well.) 

 Ex-aid and Parado: And Kamen Riders! (Both Riders' fists began to glow a rainbowic aura as well, preparing for a Critical Finish attack to whatever the Planeptune Four are attacking.) 

 Planeptune Four: Ike!!! (Purple Heart and Purple Sister fired a blue and purple beam as both Ex-Aid and Parado charged and prepared for a punch.) The greatest summer vacation in the history of Gamindustri!!!! 

 Emu and Neptune: Kamen Rider Ex-aid X Hyperdimension Neptunia: The Gamindsutri Heroes!

 (The scene changed as Ex-Aid, still inLevel 39 Double Fighter Gamer, and Purple Heart, still in her new form, standing beside each other as the title logo of "The Gamindsutri Heroes" appeared on the bottom left.)

 Emu and Neptune: M's and Nep's Summer Vacation! 

 (The scene changes again as we see Emu standing in front of Adult Neptune while the sun is setting behind them.) 

 Adult Neptune: You know, my gut tells me to do something to ya. 

 Emu: Huh? What is it? 

 (Adult Neptune walked closer to Emu as she grabbed Emu's head.....) 

 Adult Neptune: This.

(And kissed him on the lips.) 

 Coming soon!
