In the ghost ship belonging to the undead pirates, the pink haired female pirate Liliana went to the captain quarters before knocking then the person from the other side let her come in as she enters the room that used to be her quarters.

Liliana: So, when will it be the time for us to strike. I've been waiting for the chance to challenge anyone that will keep me entertained for my boredom.

She said, staring at the woman sitting on her captain seat, Dahut the Pirate Queen.

Dahut: Ara there's no need to rush my child it will soon be time for us to attack Union City but for us we need to wait for our vixen friend return.

Liliana: Oh are you talking about that damn fox woman. I don't understand why are you even friends.

Dahut: Let's just say I own her my life. She is someone that I respect and who I consider as a friend.

The sound of footsteps draws their attention on the newcomer that have just entered the room.

???: Hope I wasn't interrupting anything what the both of you were discussing about.

Dahut: Don't worry you didn't interrupt anything you came just in time.

Liliana: *huff* I think you shouldn't be here or interact with us.

Dahut: *stern* Don't be rude to her. Or do you want me to humiliate you in front of everyone just like last time?

The reminder of being humiliated made Liliana grinds her teeth in frustrated and not say another word.

Dahut: Now then, have you found anything while you were surveilling the area, Tamamo-no-Mae.

The beautiful kitsune woman named Tamamo-no-Mae or Tamamo for short answer Dahut's question.

Tamamo: Nothing much only about people going on their days or heroes that goes to the academy called Union Academy where were planning to attack, but also...

She held her cheeks smiling while her tails sway left and right.

Tamamo: *blush* I did met a handsome man on my way back here.

Dahut: Ara? Is that so? Mind telling us about this handsome man you speak of.

Tamamo: If you insist I'll gladly tell you.

Flashback

Tamamo-no-Mae was strolling across a street all alone and has been observing the area. As she was walking, she suddenly bumps into someone.

Striker: Oops sorry about that Miss, are you all right?

She looks at the person to be Striker seeing him made her feel attracted towards him for some reason.

Tamamo: Why hello there handsome~ And yes I'm quite all right~

Striker: Uh, good to know you're fine. You know a lady like you shouldn't be walking alone without protection as there could be people taking advantage towards you.

Tamamo: I can take care of myself but thank you for the concern, a fair maiden like me am flattered to a gentleman just as yourself.

Striker: Well, uh, I was just doing the right thing helping someone out and happy to help you, Miss...

Tamamo: Tamamo. Call me Tamamo.

Striker: Tamamo. That's a lovely name. Since you're fine I'll be on my way. Name Striker by the way, take care.

Flashback end

Tamamo: He was such a gentleman kind, concerning and dreamy, something I like in a man, no, a husband I have been searching for and I think I may have found the one. When I get the chance to see him next time I'll make him as my partner and husband when this mission is over.

Tamamo was happily daydreaming having a wedding while getting married to her Destin one. Tamamo got out of her daydream and she did however notice Dahut has a puzzled look on her face.

Tamamo: Is there is something wrong, Dahut?

Liliana also noticed this as Dahut snap out and noticed there are stares.

Dahut: It's nothing I was just curious about something. This Striker person did he tell you his last name?

Tamamo: *shook her head* No, he only told me his name. Why do you ask?

Dahut: ...Nothing serious, I was just curious that's all.

She said but there was something hidden in her tone that Tamamo and Liliana picked up like she was hiding something from them. Dahut stand up and walk straight towards the door.

Dahut: Let's not keep our friend waiting as it's time to release him and to begin our mission to attack Union Academy.

The two didn't question her but just follow behind. Making their way towards a door before Dahut open it, as they went inside the room someone is already inside and have been waiting for them.

???: So you finally arrive here to see me. You have kept me waiting and I almost was about to lose my patience.

Dahut: Apologies for keeping you waiting but rest assure there won't be any further delays since we will begin what we came here for...

Dahut: Kokuyo.

Kokuyo: Tsk. This better be worth my time you brought me here just so I can fight a strong opponent and crushing the weak that are those beneath me.

Dahut: Oh don't you worry you won't regret this, and also...

She showed him a wanted poster that has the Gokaiger on it.

Dahut: Just make sure you do not kill these pirates since they caught my interest. The red one seems to be there leader, if you do encounter them make sure to bring them alive.

Kokuyo: *huff* They don't seem a worth of my time if they prove to be strong obstacles I'll may consider.

Liliana: Ok, great he seems to agree. Now let's hurry up and get to pirating already.

Dahut: Fine, let's not waste any longer and getting started.

Meanwhile

Okuyasu: So let me get this straight, you two are siblings that were reincarnated as Rimuru from "That Time I got Reincarnated as a Slime" and Kumoko from "So I'm a Spider, So What?" in the world of High School DxD and now rule the world as Gods and protectors even having a replica of the nation of Jura Tempest Federation.

Been a half an hour Satoru and Wakaba tell about their life story living in the DxD world how the two reunited around the events of Season 3 then defeating and beating the crap out of Rizevim early on as well wiping out the Hero Faction with Cao Cao dead the world has been in peace so far.

Satoru: So yeah that's pretty much our life story but there has been some interesting people we have met like that one time a Kamen Rider came to our world by accident and he is from an alternate world at a different DxD universe the guy didn't know what a Kamen Rider is until I explain to him and return him back to his own world.

Okuyasu: Wait you guys met a Kamen Rider, who was he?

Satoru: His name is Rone Miura. In his world he is Kamen Rider Cross-Z Magma but here's the thing, his rider form is his Balance Breaker and he called himself the Magma Dragon Emperor basically making him as the third Dragon Emperor than the Red and White.

Okuyasu: Are you serious?

Satoru: Well that's what Rone told me. I'd once had this thought that maybe it wasn't a power he was born with but given to him instead. But hey, it's just a theory.

Wakaba: Anyways, moving aside. Okuyasu, you did tell us you came from another dimension so how did you ended up here in the first place?

Okuyasu: Well it happened during the time I was spending time at the park with my harem along with my daughter who is from the future.

Satoru: A Future Trunks situation?

Okuyasu: Something like that. As I was saying, all was fine until two portal suddenly appear randomly I was pulled in the portal while my daughter was taken from the other, the next thing I woke up I was in the same exact park then I checked I have my valuables are still there hoping I didn't lose anything and that's where I notice my Morpher has changed.

Okuyasu pulls out his Rainbow Morpher and show it to them as they had a good look at it.

Okuyasu: Before it was an upgraded version of my Rainbow Morpher now it's change to what it once was when I first found it to its original state. That portal must've been the cause of its change and without my upgrade Rainbow Morpher I can't go to my power up form as the Golden Rainbow Ranger.

Wakaba: Well we can help solve your problem and find your missing daughter, no questions asked.

Okuyasu: That's generous of you. Thank you. Um, should I call you Kumoko, Shiraori or White? I do remember the protagonist of the spider anime has other names.

Wakaba: Just call me by my disguise name Wakaba for now.

The three of them suddenly heard explosions from on Union City catching their attention.

Wakaba: What the heck was that?

Satoru: Don't know but it seems trouble.

Even more explosions keep occurring as they can hear the screams of the citizens being terrified in fear.

Okuyasu: Whatever is going on Union City a villain is involved and I won't just watch letting this keep happening because... It's Morphing Time!

Satoru and Wakaba witness Okuyasu transform into his Rainbow Ranger form as he then strike a pose.

Rainbow Ranger: Made of Pure Morphin Grid Energy! Rainbow Ranger!

Wakaba/Satoru: Wow!

Rainbow Ranger: Wild Access! Soaring Eagle!

Rainbow Ranger then activates the Yellow Wild Force Ranger ability as he leaps into the air and flies off to Union City.

Satoru: Let's follow him and see what's causing all this commotion.

Wakaba: *nodded* Alright.

The two took flight into the sky and follow him from behind making their way towards Union City.

Meanwhile at Union City

The heroes were busy holding off undead creatures. There were Union Academy individuals fighting off the monsters, but they're being overwhelmed as more kept coming. Leading the creatures was Kokuyo as he order them to cause chaos to Union.

Kokuyo: So these are the city's heroes, to be honest I'm quite disappointed, none seems to be that strong. You're all pathetic not even give me a good challenge, weaklings like you should all die beneath my feet!

Kokuyo said mocking the heroes of Union that are angry towards him, one of the heroes was brave enough to stand up against Kokuyo, what a foolish mistake.

Random hero: We were not talked down to the likes of you villain like you! We protectors of Union City will continue to fight for the people as long as there's hope, us heroes we'll always-

Instantly from everyone shock and horror, the hero that tried to rebel had their head blown off as then body fall to the floor. Kokuyo had two of his fingers in the gun motion as he looks at everyone that witness him the brave hero that lost their life.

Kokuyo: Anyone else wanna go against me?

No one says a word nor they didn't want to as they were too afraid. But suddenly the undead creatures were getting shot one by one then they exploded. This surprised everyone even Kokuyo as they look up to see a red pirate ship floating above them, coming down for the red pirate ship Gokaiger all six of them come down putting their blasters at Kokuyo.

Gokai Red: Since no one don't have the guts to go against you then we'll have to step in and take you down ourselves.

Kokuyo smirks seeing six of his targets Gokaigers are here.

Kokuyo: So you guys must be the Gokaigers, I've been expecting y'all to show up.

Gokai Green: You've been expecting us to show up? Does that mean you did all this attacking Union City just to get our attention?

Gokai Yellow: What is an ogre like you want with us? This really could cause a bad image to the Yokai Faction if one of their own went out of line attacking people.

Kokuyo: I am not part of the Yokai Faction nor associate with other faction in general, who I work for is none of your concern as what should you know I have been tasked of catching all of you alive. So you should either surrender now or these weaklings you're protecting will die

More undead creatures appear but with gargoyle golem monsters in the mix.

Gokai Blue: Looks like he brought some new friends over.

Gokai Red: You think it will be easy to take down those gargoyles?

Gokai Blue: Only one way to find out is the fight them head on.

Gokai Red: Then let's not waste any time and do just that. Let's make this showy!

Rainbow Ranger: Don't leave me out of the fun!

Suddenly everyone heard a voice from above as then something crash between the middle the Gokaigers and the enemies side. It was then they see a silhouette from the debris as it settles now having a better look as standing there was Rainbow Ranger causing shock from his unexpected arrival.

Kokuyo: Who the hell are you I wasn't told that was a seven member?

Gokai Red: Who are you?

Rainbow Ranger: Someone you can consider as an ally. I'm the warrior made of Pure Morphin Grid Energy! Rainbow Ranger! At your service!

Gokai Silver: Rainbow Ranger...?

Gokai Pink: Is he a Super Sentai like us?

They watch as Rainbow Ranger let out a mighty battle cry as he charge at the enemy, one gargoyle golem monster swing its large sword at him to which he avoid the attack by jumping up at the gargoyle golem and use his sword to slice its body in half. Then other monsters came to avenge their fallen comrade as Rainbow Ranger face them all head on.

Gokai Red: Come on guys let's help him out!

The Gokaigers joins the fight and help Rainbow Ranger as they work together to take down the monsters. While this was happening Satoru and Wakaba were looking down on the battle observing. No one haven't noticed them as they made their presence unnoticeable from any higher being. Both were puzzled when they lay their eyes on Kokuyo as Satoru said.

Satoru: Benimaru...?

He said thinking of one Rimuru's trusted subordinates Benimaru as Kokuyo is the exact copy of him but he's completely different.

Satoru: Is it really him he looks so different.

Wakaba: Could this be his doppelgänger? We both know something like this has happened before with Range, Gobta, Shion, Gabiru and Phobio?

Satoru: ...It could be but I don't want to assume if this has anything to do with "her" it's just not possible.

Wakaba: Even so it can't be a coincidence. Why not ask Ciel to analyze Kokuyo to gather any information about
