In Marinette's house, Marinette help Alya out on her Ladyblog.
Alya: Thanks again for helping me out for the day, girl.
Marinette: No problem. I know how much you love keeping track of Ladybug and Black Panther's battle between what akumatized villains. *Alya turned around and she spotted a black box.*
Alya: Hey, what's that black box over there? *Marinette turned around too and her eyes were wide opened.*
Marinette: Oh, it's mine. I don't allow people to touch it, only I do. For safety reasons.
Alya: Oh, okay, then. *Soon, Marinette's phone ringed and she look at it. It's Master Fu.*
Marinette: I'll have to take this. I'll be right back.
Alya: Okay. *She keep working and Marinette take her phone and answer it in the stairway.*
Marinette: Hello?
Master Fu: Marinette, I need you and Luka to come to my house, it's an emergency.
Marinette: What's wrong?
Master Fu: I'll explain to you both, right now I need you both to come here. Quickly.
Marinette: Okay, we're on our way. *She hang up and go to her mom and dad.* Mom, dad, I'm going to visit Luka for a little while. I'll be right back.
Sabine: Okay, sweetheart.
Tom: Be safe.
Marinette: I will. *She get her phone and text Alya and tell her what's going on. Then she replied back. "Okay. I'll be heading home soon when you get back."* Phew. That's taken care of. *She leave the house and call Luka next.*
Luka: Hey, Marinette.
Marinette: Master Fu needed us at his house.
Luka: What's going on?
Marinette: I'm not sure, but something urgent.
Luka: I'm on my way. *He hang up and he put his phone in his pocket and he leave his house and go to Master Fu's house too.*
Outside of his door, Luka opened the door and they see Master Fu.
Marinette: You wanted to see us?
Master Fu: Yes. I have something very important to tell you both. Hawkmoth found out who I am.
Luka: How did he find out?
Master Fu: I was out doing my weekly grocery shopping, I spotted the peacock holder on top of a tall building.
Marinette: (Mayura!)
Master Fu: I have to lay low for a while until things blow over or he'll get the miraculouses. I need one of you to guard these with your life so he won't find them.
Luka: I'll do it.
Master Fu: Are you sure, Luka? *Luka looked at Marinette and hold her hand too and book at Master Fu.*
Luka: You trusted me the black cat miraculous, you can trust me with the rest of them.
Master Fu: Very well. But only use them for allies help. *He lend Luka the miracle box and Luka hold the box firmly.* And one more thing, you must not tell anyone about the box, you must hide it so no one will find it, okay?
Luka: Yes, master.
Master Fu: Very well. I trust you to guard the miracle box with the remaining miraculouses in here. If these get into Hawkmoth's hands, he'll use them for evil. *He take off the turtle miraculous and lend it to Luka and Luka put it on his other wrist without the bracelets and only the black cat miraculous.*
Marinette: We can't let that happen.
Master Fu: Thank you. *They get up and leave his house, Master Fu saw them leave together.* I hope I can trust them both for this.
