(In the busting Metropolis of Neo Tokyo...)

(A certain Kamen Rider is seen face to face with a random thug who was trying to rob a bank. As he places his GX-05 Kerberos in the ground, the thug charges at him, only for the Rider to draw the GM-01 Scorpion and start shooting his left arm.)

Thug: Damn bastard...

(The thug keeps charging at the Kamen Rider, who shoots his right arm before pulling out the GS-03 Destroyer to stab his left leg and kick him in the gut. Suddenly the thug's goons come in and try to charge at him, only to be punched down as one of the thugs is slammed down, and the last goon is kicked. The Kamen Rider then picks his GX-05 Kerberos and types its code.)

RELEASING SAFETY!

(He turns his GX-05 Kerberos into its Vulcan Mode.)

(And he shoots the goons down before turning to pick the thug up.)

G3-X: You're under arrest!

(G3-X takes the thug to the prison, and then he goes to his personal base of operations.)

(As he gets in, he removes his equipment, revealing himself as Matthew Harper.)

Matthew: Another job done.

(He then prepares to drive away as he prepares to return home.)

(Timeskip)

(Matthew is seen arriving at his house.)

(As he gets inside, he goes to the kitchen, where he prepares his dinner. He makes one of his favorite foods: Omurice.)

(As he places the Omurice on his plate and goes to the table, he sits down and prepares to eat.)

Matthew: Itadakimasu!

(Matthew eats his Omurice, and then goes to his room, where he watches the news about his alter-ego arresting the thug, and then some news about sports. After that, he goes to take a bath, and finally he prepares to sleep. As he goes to sleep, he fails to notice a some lights blinking at his living room.)

(Next morning, Matthew is seen waking up as he sees seven girls looking at him.)

Makima: Oh, you're finally awake.

Esdeath: I must admit, you look cute when you sleep though.

(Matthew suddenly sees a crimson haired sleeping beside him, completely naked, making him blush madly. The girl then wakes up and gives him a passionate kiss, much to his surprise and the other girls' jealousy.)

Rias: How are you, my future husband?

Akeno: Ara ara... don't hog him to yourself, buchou.

Marin: (to Matthew) I know you look confused. We will explain it soon.

Midnight: But you must admit it, Tiger. You have just hit the jackpot.

Boa: Yeah, not everyone gets to have such beautiful ladies like me, right?

Saeko: Well, allow us to introduce ourselves. I'm Saeko Busujima.

Makima: I'm Makima.

Esdeath: Esdeath is my name.

Rias: I'm your wife, Rias Gremory. This is Akeno Himejima.

Akeno: (smiles) And we all know who you are. You're Matthew Harper, a super cop known as Kamen Rider G3-X.

(Matthew gets shocked by seeing that the girls know his name and his job.)

Marin: Anyway, I'm Marin Kitagawa, ready to cosplay.

Midnight: I'm Midnight, and from now on, we'll be working together.

Boa: And I'm Boa Hancock.

(They then explain how they were brought to his world, and he became shocked about it, and at the same time, he got happy since he never got to date anyone, especially because of his job which is very tiring, especially because he does all of his job alone.)

Matthew: I don't even know what to say... I guess I might get used to it. Now if you excuse me, I gotta prepare some breakfast.

Girls: (in unison) I can't wait.

(Matthew goes down to prepare the breakfast as he smiles, knowing a new journey in his life has started.)
