(In a village, everyone is seen enjoying their peaceful life on a sunny day as the birds are chirping. A young boy named Kairi Korbac is seen walking in the sidewalk, minding his own business. He was having trouble since his parents died.)

Kairi: Why does the world have to be so cruel? My parents die and nothing is done about it? Grr, why did this have to happen to me?

(He keeps on walking until he sees something on the floor.)

Kairi: What's this?

(Kairi touches it, and suddenly a black dragon comes out from a mirror.)

(The dragon roars at him, much to his confusion.)

Kairi: Where did this dragon come from?

(The villagers get scared of the dragon.)

Villager 1: Is that...?

Villager 2: It can't be...

(Kairi looks at the deck, and sees the "Advent" card as he turns to the dragon.)

Kairi: Did I...

(The villagers start running away, which confuses him.)

Kairi: This is getting more confusing...

????: Hey you!

(Kairi turns to see a warrior with a rod, and then he points at himself.)

Kilik: Yes, you. Do you know what you just did?

Kairi: Uh... not exactly...

Kilik: You have unleashed the most dangerous creature ever. I suggest you to hand over the deck to me, or there will be consequences.

(The dragon shakes his head, and then he gestures Kairi to point the deck at the mirror.)

Kilik: (glares) Don't you dare...

(Kairi points the deck at the mirror, and the V-Buckle appears in his waist, much to his shock.)

Kilik: (aims his weapon) I'm warning you. If you put that deck in your waist, I'll be forced to make you listen... to the raging of my soul!

(Kairi gets confused, but places the deck in the buckle, becoming Kamen Rider Ryuga.)

(Kilik then gets in his fighting stance.)

Kilik: Alright, I warned you!

(Kilik charges at Ryuga as the screen goes black.)

ADVENT!
