Ryalight Glimmer: Uhh. Where am I?
[Ryalight notice a computer room and walks up to Ansem's computer]
Ryalight Glimmer: Cool. Let's see. [looks at Laval and his friends] New Keyblade wielders?

Ryalight Glimmer: Whoa! Who are you?
Braig: I'm Braig. You must be Ryalight Glimmer. You think I scared you? As if.
Ryalight Glimmer: Nice name, but, how did you know me?
Clyde Bandicoot: [arrives with Young Xehanort] He saw your films.
Ryalight Glimmer: Clyde. I guess Ryvine did pick you.
Clyde Bandicoot: Yes. This boy is Xehanort.
Young Xehanort: You are?
Ryalight Glimmer: I'm Ryalight Glimmer. Kamen Guts hater and Ryan from another dimension. You think there are other heroes?
Young Xehanort: Yes. Thier worlds are gone to darkness. I think you got a Keyblade. Like Master Xehanort and Ryvine Sparkle.
Ryalight Glimmer: Yeah. I think we can be friends. Know this. There are more Keyblade wielders poping up. Trust me. I know some villains to get.
[Ryalight chuckles as he look at a photo of Rianna]
The Darkness awaken
In the Digital World, Duskmon is looking at the Sea
Duskmon: This World is not enough for me.
The Light in the Darkness
Dogmon and his friends arrived in Digital Castle Oblivion
Ladybugmon: What is it?
Dogmon: I don't know, I haven't seen that Castle before in the Digital World. Must be a New One, I guess.
Anteatermon: You think this is castle is where we go to?
Dogmon: I guess. I wonder if Kumamon and his friends are here in this Castle?
Goatmon: So what do we do?
Dogmon: Well, let's go inside.
They went inside the Castle, and they're in the Chamber of Waking
Then they saw Kumamon, Kotemon and Bearmon sleeping
Dogmon: Kumamon, Kotemon, Bearmon? Is that you?
Flamingomon:￼ Hello? They're not awaking up.
Dogmon: Let me try.
He tried to wake them up, but it's not working.
Ladybugmon: I think their hearts has been asleep.
Dogmon: You think?
Ladybugmon: I don't know. If their heart has returned they will very well awake, or if they're not. Then they will sleep like this all for eternity.
Dogmon: Oh no.
Ottermon: I guess they are in somewhere we know. The realm of light.
Anteatermon: Guys, I Found a ￼Letter from Kazemon, Beetlemon and Socerymon.
He open it and read it
Dogmon: (Reading) Dogmon and friends. If you read this letter, we already left this world to find Loweemon. Since you left the Digimon World 2 years ago. Kumamon, Kotemon and Bearmon has lost their hearts back at the Digimon Graveyard. We leave them here in the Chamber of Waking to keep them safe. This Castle is Seraphimon's Castle. We locked the old Digital World away. Our Creator created a New Digital World. We lost Lobomon and Agunimon back at the Digimon Graveyard. We lost everything in the Digital World thanks to Quartzmon. So, we went off to find Loweemon, cause we know where to find him. If you know, we're missing... Come find us. Signed, Kazemon, Beetlemon and Socerymon.
Dogmon is crying, because he lost everything in the Digital World. Even their friends, Kumamon, Kotemon and Bearmon has lost their heart, Agunimon and Lobomon are gone forever, and Kazemon, Beetlemon, Socerymon and Loweemon are missing. And he and his friends weren't there with them after they left the Digital World
Dogmon: (Crying) They are gone...
He kneel down crying
Ottermon: Don't be sad.
Dogmon: I know. But we lost our friends from an Evil Digimon (Crying)
Goatmon: It's alright, Dogmon. Maybe we should find them and bring them back.
Dogmon has cheered up
Dogmon: Yeah, maybe we could find them somewhere.
Goatmon: And you remember what Kazemon said after she gave us those Wayfinder
They bring out their Wayfinders
All: Unbreakable Connection.
Dogmon: We know...
They are going to leave and they look at Kumamon, Kotemon and Bearmon
Dogmon: This place might be lonely. But you still have your best friends with you, and you'll be safe. We will come back to find your friends and your hearts. Good bye.
They left Digital Castle Oblivion and they wear those Black Coat and they heard a Voice
????: (Voice) Please save me and my crew.
They know that Someone is in the Realm of Darkness after their world is gone
Dogmon: Everyone, hang in there, we're coming. Even you, Doki.
They went off to find their friends and save the people, even reuniting Doki and his friends
The dark in the light
[Rianna is at Yen Sid's tower]
Rianna F-Fiona: Master Yen Sid. I think we are one step closer to where the heart of the leader of the Robot Monkey team is.
Yen Sid: Of course, but since he was struck down by Skeleton King and Antuari. He, Eraqus, Eon, Jinmey, Seraphimon and Ophanimon's star has been blinked out.
Rianna F-Fiona: Yeah. And we can save them together.
Yen Sid: Hmm....The question is... What will Ryvine Sparkle do next with Xehanort?
Rianna F-Fiona: Ryvine Sparkle? But, his two halves are gone. There was Mal, who leads the Heartless.... And Vixyner, who leads the Nobodies. Did Ryan and Sci-Ryan already defeated them?
Yen Sid: Correct, those two met their end. However, therein lies exactly our problem. Their destruction now guarantees the original Ryvine's reconstruction.
Rianna F-Fiona: What do you mean?
Yen Sid: Ryvine's heart, once seized by his Heartless half, is now free. And his body, which had become his Nobody, has been vanquished. Both halves will now be returned to the whole. In short...this means Ryvine and Xehanort will return.
Rianna F-Fiona: You think... Ryvine and Xehanort are gonna try something?
Yen Sid: A Man like Xehanort and Ryvine will have left many roads open.
Rianna F-Fiona: Well. I do not care what they are planing. Me, Magianort and my friends will be there to stop them. And Ryan and Sora too.
Yen Sid: Yes, they are indeed strong. But...not true Keyblade Masters, like you.
(He continues to stroke his beard)
Yen Sid: Tell me...would a single one of you suffice if what you faced was not a single one of him?
Rianna F-Fiona: Huh? What are you saying?
Yen Sid: Rianna. I told Mickey and Optimus to get Ryan, Sora, Riku, Cody, Sci-Ryan and Crash for me.
Rianna F-Fiona: Ok. But, why?
Yen Sid: To show us the Mark of Mastery.
