Disclaimer!: This is part two of a crossover event! From here on out it's part 2.
If you want to see part one, it'll be in Detective of Gamindustri (Hyperdimension Neptunia X Kamen Rider W)
You understand?
If so, you may proceed.

(Back in W. Iron's world)

W. Iron: so you really were a Rider?!

Tsukasa(Decade): that I am.

Shade(Decade Dopant): Grrrr....

Zx. Iron: well this'll be tough.

(The decade dopant takes out a card and throws it towards his waist)

"aTaCkRiDe:SlAsH!"

(A sword materializes in the dopant's hand)

Iron & W. Iron: Megamerge!/Henshin!

Model Z & X: Biolink established. R.O.C.K. System online.

"Cyclone! Joker!"

W. Iron(W): let's do this!

Iron(Zx): yah!!!!!

(The decade dopant matches the three combatants well! Every attack they threw, he countered!)

W. Iron(W): Damn it!

(The dopant takes out another card and places in his buckle)

"FiNaLaTaCkRiDe:D-d-DeCaDe!"

(The dopant prepares for a kick until a fired bullet knocks the dopant down, interrupting the attack!)

Decade Dopant: who dares?!

???: You guys seem in a fight, may I join you?

(A man in a white outfit carrying a gun would have arrived!)

W. Iron(W): who- no, what are you?

???: Daiki Kaito, an inter-dimensional thief, but also...

(Kaito takes out a blue card)

Kaito: a Kamen Rider...

Decade Dopant: Grrrr....

Kaito: henshin.

(Kaito loads the card into his gun)

"KamenRide..."

(Kaito fires the gun!)

"Diend!"

(Kaito transforms into a rider!)

Decade dopant: 4 of you? Might as well even the odds.

(The decade dopant places a card in his buckle)

"AtTaCkRiDe:IlLuSiOn!"

(The dopant creates multiple clones of himself to outnumber the others)

Iron(Zx): 9 to 4.... Not exactly good odds...

Kaito(Diend): you think I came alone?

(A pink energy arrow snipes one of the clones!)

Iron(Zx): I recognize those arrows!

(Ami stands on top of a light post with her EXE-Arc in Bow form!)

Iron(Zx): Ami!

(Ami looks at Iron/Zx and pouts)

Iron(Zx): I know, I've been gone far too long, I'm sorry I made you worry....

(Ami sighs and smiles at Iron/Zx)

W. Iron(W): ah, young love...

Iron(Zx): W-wha?!

(Both Ami and Zx. Iron/Zx blush redder than ever)

W. Iron(W): I'm kidding! Jeez, relax!
Or am I?

Iron(Zx): in any case, how about the others?

(One copy got struck with Ice and another struck by Fire as Deva/Levia and Agni/Fefnier arrive!)

((The two are in Model L and Model F form))

Iron(Zx): glad to see you here!

???: Missed someone Iron?

(A huge cyclone send one copy into the side of a building as Marlow/Harpuia arrived!)

((She is also in Megamerged form))

???: You think I'm just gonna let you have all the fun?

(Steel arrives)

"Accel!"

Steel: Let's...Henshin!

(Steel transforms!)

Decade dopant: 9 of you?! Grrrrr.........

Iron(Zx): I think this man has had enough fun.
Let's take care of him!

Everyone: yes!

(Everyone battles at least one of the copies with each of the copies getting taken out in different ways!)

"Accel! Maximum drive!"

(Steel/Accel tears into a copy with his sword and it explodes)

Steel(Accel): Despair is your goal.

(Agni/Fefnir blows up one of the copy!)

(Deva/Levia freezes the copy solid and breaks it, shattering the copy!)

Kaito(Diend): let's end this.

(Kaito/Diend inserts a card into his gun)

"FinalAttackRide:D-D-Diend!"

(Kaito/Diend fires a massive laser beam from his gun destroying the copy!)

(Iron/Zx slashes through a copy while Ami pierces one of the copy with enough energy arrows to destroy it!)

(Eventually, the real deal would be the last one)

Decade Dopant: this can't be!

Tsukasa(decade): too bad, it is.

(Tsukasa/Decade takes out a card and inserts it into his driver)

"FinalFormRide: W-W-W!"

Tsukasa(Decade): this may tickle a little.

W. Iron(W): wait, wha-

(W. Iron/W gets separated into two halves which eventually make two riders!)

"CYCLONE! CYCLONE!"

"JOKER! JOKER!"

W. Iron(Cyclone) & W. Iron(Joker): What the...

(Tsukasa inserts one last card)

"FinalAttackRide:W-W-W!"

(Tsukasa/Decade, both W. Iron's, and Iron/Zx prepare for one last attack)

Tsukasa(decade) & Irons(Cyclone and Joker): Triple Extreme!

(They attack the decade dopant with a W shaped rider kick, destroying the last one, not only reverting shade back to normal, though unconscious he falls through a tear in space and time and it closes behind him...)

Iron(Zx): how in the-

???: ONORE DECADE!!!!

(A guy who looks a researcher would be shouting at Tsukasa/Decade)

Tsukasa: Narutaki, can you just leave me alone for 10 minutes?

Narutaki: Hell no! I was about to set this world on it's proper path, but you messed everything up.

(The two W. Irons revert back into one and dehenshin as iron walks up to Narutaki)

W. Iron: I don't care who you think you are, but I decide my own path, not you.

Narutaki: grrr-

(Narutaki's hat would be missing)

Narutaki: where did my-

(Kaito would make off with Narutaki's hat)

Narutaki: Grrrr....this isn't over, Decade!

(Narutaki runs after Kaito)

Iron: in any case, we'll need a way home.

Tsukasa: I can help with that.

(Tsukasa creates a distorted wall of some kind)

Iron: well, this is goodbye, W.

W. Iron: looks like it, take care...me.

Iron: as do you.

(The two have a baton pass similar to show involving a team of heroes rather than just one)

(Iron enters the distorted wall)

W. Iron: hey, Ami?

(Ami tilts her head to the side)

W. Iron: I can tell you like my other self, so... Don't give up on him.
No matter what.

(Ami blushes a little, but nods before heading into the wall followed by Deva and Agni and then the distorted wall faids with Tsukasa also leaving)

W. Iron: well, I'm beat...

Steel: same...

(The two friends head indoors to sleep...)

???: Time this world experiences the true power of the ASIC!

"WEATHER!"

(Meanwhile...in Zx. Iron's world...)

Gwain: Where The [Censored] have You Been?!

Iron: it's a really long story....

(To be continued....)
