Aether is having to relax in the harbor when the ship arrived it was Amber and her friends.

Amber: Aether!

She rushed to him as she hugs him.

Amber: Thank God, you're okay.
Aether: Don't worry about it, Amber, We are all okay.
Amber: We?

Then his friends arrived on time.

Lumine: Oh hey, Amber.
Amber: Hey.
Keqing: How have you been, old friend?
Amber: I'm fine.
Eula: I'm glad that you guys are okay.
Aether: I know.
Barbara: I have to take care of the patients.
Bennett: I'll go with you.
Jean: We heard the news about what happened in Inazuma.
Sara: Yeah, all of the nations heard about the news.
Ei: Everyone I hate to say this but.
Jean: What is it, Ei?
Ei: Everyone, Godzilla has returned.

They were shocked about Godzilla's Existence.

Venti: What?
Diluc: Meeting, Right now!
Kaeya: Let's go.

Aether and his Allies are in the house having a conversation about Godzilla.

Ganyu: I don't understand, We thought it was a myth.
Aether: Yoimiya, Why didn't you tell us about that Monster?
Yoimiya: I haven't, We all thought they were all myths.
Lumine: Yoimiya's right, They just appeared for the second.
Ei: And Rodan, Appeared out of Volcano.
Beidou: Whatever the reason, They must have been awakened from their slumber.
Jean: We have no idea where did they come from.
Aether: With Inazuma's Destruction ain't proof I don't know what is.
???: Ohh, it's real, alright, everyone.

Then they turned and looked at Beidou's Father, Kung Chun.

(Kung Chun is a made-up name for Beidou's Father so in this AU Beidou has her Father)

Beidou: Father? How do you know this?
Kung Chun: It's time that I showed you the truth, I encountered him back in my Navy Days.

(Flashback)

10 Years Ago

Me and my crew were on the high seas, suddenly there was a loud bump. The crew and I went out to investigate then out of the water, Osial appeared along with the spider, we fought against the feral beasts but we were overwhelmed. We all thought it was over for us, but then out of the water There he blows. It was the biggest monstrous damn reptilian monster that my eyes have ever seen, Godzilla fought against Osial and Giant Spider as Me, and my men desperately tried to escape and watch as their battle was fierce.

(Flashback Ends)

Aether: What happened, Mr, Chun?
Kung Chun: Godzilla is victorious as we managed to escape in that incident. He didn't attack us, instead, he swam away into the depths and was never seen again, through these years, I haven't heard of him and his name in 10 years until now. But the truth is, me lad, I never had a chance to thank him.
Beidou: Wait, Father. So you knew about this, That Monster, this whole time. Why didn't you tell me about this?
Kung Chun: Because I wanted to protect you when you get older enough to find the truth about him.
Beidou: You protected me from the lie?!
Aether: Beidou! Enough.
Beidou: *sighs* I'm sorry Father, I didn't mean to yell.
Kung Chun: It's okay, Beidou, We've been through worse.
Aether: We need to find some answers about Godzilla's Existence and the other Titans.
Ei: I hope, We're able to.

Somewhere in the Sea

Godzilla swam towards the Liyue after he felt the presence of MUTO Prime and Queen MUTO even after Hibernation, He's ready to face him.
