The reason why any edit is undone is practically always listed in the articles history. https://swordartonline.fandom.com/wiki/Kirigaya_Suguha?diff=next&oldid=163772

In your case, you:
 * 1) Never add any actual reference for your claims. Mentioning a Youtube channel doesn't count as referrencing. No one is going to guess which channel you are even referring to, let alone go through the entire channel just to find a random tidbit like that. You need an actual link to a specific post that mentions it for your claim to be counted as sourced.
 * 2) You break the page with your edit. In 2 of your edits, you copied over the referrencing error message for who knows what reason. Since the message has a ref tag, but no closing tag, anything below it gets ignored from the article.
