How do you delete a Pixiv account?

Answer 1

Look at where the help button is at the bottom of the page.

Remember it.

Change the language to Japanese (日本語)

Go to the help page (ヘルプ)

Then, in the second set of questions, click the last one. That's the one about closing the account.

This will take you to the answer. Within the answer, there is a link. Click it.

It will ask you "are you sure" and a bunch of other stuff on the next page, there will be an obvious green "continue" button. (the only button you'll see..)

Then continue from there. It's just a screen to enter your password, and a reason for leaving. (idr the order)

Remember, during this process, Google Translate is available. It helps.
