I'm crashing and shooting three

After time travel, he became a director and decided to make Honkai into a movie!
A priest who looked like Otto was found from the church next door, and a girl with the same name as Bronya and Seele was adopted in Siberia, and a girl who was very similar to Raiden Mei was found, and they were successfully persuaded to become their own actors.
It's just that he didn't know that the world he traveled through was the Honkai world, and all the characters looked at him in the script and said in surprise.
Otto: "When I know how to save Kallen, I'll kill you! Wait until the blood on my head lights up!"
Raiden Mei: "Purple! Purple eyes! The second female lead must be me! As long as I know the plot, I will definitely be able to save Kiyana!"
"Sorry, Lei Movie has been decided to be the second female lead in this play."
Raiden Mei: "??? I really can't do anything..."
"No, there is one thing only you can do!"
"whats the matter?!"
"I'll give you the box lunch of the crew."
