When they heard someone, they moved closer and put themselves on defense

Axel: Aniki, did you hear a voice?

Shiro: Yeah, and their voice are familiar.

Axel: Yes, but who?

?????: maybe one should show up, that way you will be able to recognize us

They show up and reveal themselves, it was Shinji Kido and Ren Akiyama.

Shinji Kido and Ren Akiyama

Axel: shock S-shinji Kido and Rend A-akiyama!!!

Shiro: Nani?! But why are you two here?

Shinji: It is because in you we have chosen to become our successor, but also to give you a mission.

Axel: What mission and also me and aniki become you and Ren-san successor?

Ren: sight It's because it's about Odin.

Both authors are shocked, Odin, the one who tried to revive his sister with a battle royale with Kamen riders

Axel: Wait! Odin?!?!

Shiro: Huh?! Did you guys defeat him?

Shinji: Yes, but, he comes back from the dead with his mirror monsters, he goes to the world of Zenless Zone Zero

Axel: WHAT!!! Zenless Zone Zero!! But, why he goes into this world?

Ren: He try to restart the Rider War in a new world and bring back his sister from dead.

Axel: angry  呢個仆街，點解佢仲想試下當人哋因為呢場大逃殺而死嘅時候，佢已經唔係人，而係怪物. (This bastard, why would he try when people are dying because of this battle royale, he is no longer a human but a monster)

Shiro: Growl This bastard is nothing but a siscon! (Sigh) I blame Shiro and Yui's parents for abandoned them and turn Shiro into a villain.

Axel: Shinji-San, Ren-san. serious looks Me and my big brother accepted this mission, promising that we would protect this world from Odin and his monster mirrors!!

Shiro: And we will stop this goddamn War with our hands!

Shinji and Ren smile, both raise their hands, then a red light and a blue light appear in their hands and send it towards our two authors, the red light goes to Axel and the Blue goes to Shiro, the light enters the bodies of the two authors

Axel: What was that light?

Shinji: This light was our power in passing on to you, use it well, so I must give you this

Shinji makes a briefcase appear and gives it to Shiro. Shiro take the briefcase and holding the briefcase.

Shiro: What's inside the briefcase?

Ren: Open it and you'll find out what's inside

Shiro open the briefcase and see something inside, reveal it was.... The Advent Deck. Shocked to see inside, but he see the Ouja Advet Deck is missing.

Shiro: Where is Ouja Deck?

Shinji: Ouja deck already give it to someone else.

Axel: Who?

Ren: Shiki Asakura, he was from our world and son of Takashi Asakura.

Axel: What ! he's Origin Ouja's son, tell me he's not like his father!

Shinji: Don't worry, he is Anti-Hero and he fight for fun.

Axel: sight I'm glad.

Shinji: Also Axel, I have to speak in private only you and me.

Axel: Okays?

Shinji and Axel go somewhere to talk in private

Axel POV.

I follow Shinji-san, then we went far from big brother and Ren-sen, Shinji turns around with a serious look 

Shinji: Well, away from these two, Axel I have to warn of something dangerous

When I heard, I knew what he was talking about

Axel: It's about Ryuga?

Shinji: Yes, as you know, he is my shadow version, but after my fight against him, he is part of my body, now that I have given you my power, you must be careful, you must not only negative emotion appear otherwise, you will not be able to control Ryuga, do you understand?

I look at Shinji-san with a worried look, then I turn my face to see big brother, I have to keep this secret at all costs, I turn my face to see Shinji-san.

Axel: I understand

Shinji: Good, now let's join the others

3rd POV.

Shiro look to see Axel and Shinji walk up to them and see they arrive.

Shinji: Sorry about that, I had to talk to him about something

After that, Shinji and Ren open a portal to go to the world of Zenless Zone Zero

Ren: This portal will take you to the world where Odin went with his mirror monsters

Shinji: Good luck in your fight against Odin, find allies and defeat him once and for all.

Axel: 我明白 (I understand), Aniki, let's go!!

Shiro: Got it.

They went inside the portal and went through the portal.

At New Eridu. 

A portal then opens, Axel and Shiro come out of the portal

Axel: I see that we are in the Hollow Zone.

Shiro: Yeah, which mean we are in chapter 01 where we meet Anby and Billy and Proxy.

Then heard some noise

Axel: Aniki, you hear that?

Shiro: Yeah... Let's go check it!

The two authors ran to see what the noise was. They arrive and see two figure fighting the monsters known as Ethreal, this is Billy and Anby.

Anby Demera and Billy Kid

Axel: Looks! It's Billy and Anby!

Shiro: Let's go help them!

Axel: Yes!!

Anby and Billy are fighting two Ethreal as the other Ethreal attack Anby, I try to dodge their attack but their attack were together.

Billy: Anby! You're good?

Anby: Yes, and you, do you still have any ammunition? worry

Anby: It's okay, my sword is not broken yet!

Ethreal 1: Attack and charged at Anby

Billy: Anby! Look out!

Anby saw the Ethreal too late, she closed her eyes, but suddenly she heard a voice

?????: Take that your monster!!

Anby open my eyes, I see a young man who punch the Ethreal in the face

Reveal it was Shiryu as Shiro just arrive.

Shiro: Oi little bro! Don't be reckless fool! 

Axel: Sorry, but I couldn't let this watch hurt this beautiful girl smirk

Shiro: Sigh Fair enough.

Billy: Who are you two?

Axel: Nice to meet you, my name is Axel, this is my big brother Shiro.

Shiro: I'm Ngo Chan Quoc if you don't understand, call me Shiro.

 Then, the four heard the Ethreal arrive

Axel: I know we've only just met, but they tell you we'll find a hiding place.

Billy: What?! You two can't be serious?

Shiro: Nope! We are serious, buddy. We will handle them. 

Abby and Billy look at their situation, but suddenly, several bombs appear and begin to emit smoke and confuse the Ethreal

Shiro: Oi Shiryu! Here the bunny coming!

Axel: I know and my name is Axel, I want you to call it that, Shiryu is my nickname

Shiro: Yeah, I know. 

??? (Proxy): Over here!

Then sees a bangboo appear behind a container, the four run to get behind the container

????(Proxy): Nice work, all.

Anby: whispers to Billy It's a scarf-wearing, talking Bangboo...

Billy: Whisper to Anby Yeah... Wait, I know this voice! It's Proxy!

Proxy: Follow me, must take shelter before the smoke disappears

They follow Proxy to the shelter before the scene change to the shelters.

Anby: I can't hear that superior Ethereal anymore.

Billy: sight Uh, great, i fell my legs pistons are gonna break!

Axel: It's been a long time since I ran like this, right big brother?

Shiro: Yeah.... Almost every day I have to run, huh?

Proxy: Excuse me, but who are you, I don't know you two at all?

Shiro: Smirk I'm just a passing through writer, remember that.

Axel: My name is Axel but you can also call Shiryu, he's my big brother and also, sees Shiro seriously?

Shiro: What? We make the reference from Kamen Rider show, plus it's pretty cool to do that.

Axel:....Touche

Billy: I have a question, how did you and big brother get in here?

Shiro: Have you ever heard of... Multiverse theory?

Anby: The Multiverse theory, wait you mean that....

Axel: Yes, we come from another universe

Billy: Wait what?!

Proxy: No way! Shock

Axel: Yes and to tell the truth, me and my big brother really come from another parallel universe.

Shiro: In our world, you three are fiction characters from video games.

Anby, Billy and Proxy: WAIT, WHAT?!?!?!?!

Axel sighs, he takes out his phone and pulls out a video of them

Shiro: Here the video if you three won't believe me.

After they have the video, they are still in shock

Billy: shock So, we're just that character from a video game?

Shiro: Yep, and we know you guys are fiction but we treat you guys as real life person to us.

Axel: My big brother speaks the truth, we sees you as a real person.

When they heard this, they cried with joy and Billy hugged Axel and Shiro

Shiro: O-Okay, this is awkward...

Axel: A-air, I need air.

Anby: S-Sorry. Let go of them

Billy: My bad, well, actually what now?
