I recently completed Speedrun with Normal/NG and would like to apply! It seems that I already have some records of Easy/Normal NG+.

Streaming Guidelines for this game have been announced by Atlus even before the release date. https://atlus.com/smt5-streaming-faq/ There is a description of this.

The content below should be withheld from streaming: The cutscene after completing the Temple of Eternity, up until the ending and staff credits appear. Boss analysis information visible on the “Analyze” menu screen.

You will need to set up rules for the runner that follow the Streaming Guidelines.
