Here is a list of links to twitter notes on Japanese dialogues from the BNHA manga, or differences in translation and meaning between Viz edition and the original dialogue.
These are links to the original tweets, as I am not Japanese, nor a translator. Also this was posted the 15/5/21 so I will probably update it later on to add more tweets!
