Account retrieving help

Hello,

I searched forums, and couldn't find any answer, regarding this question, If there is some please, link me to it.
I'm sorry if I'm posting this in wrong section.

My problem is that I don't know email address account it registered to. I know username, and password, and email password. The thing i don't know is gmail address itself. Is there any way to check the email. I can't check it on website because of two factor authentication. I don't need email change, just to know which one it is. Hope someone could help me with this.

/Regards

Q: I lost my e-mail. What should I do?
A: Keep in mind that we do not support the retrieval of e-mails. However for the time being you may message Palutena or Mercy and ask for assistance.

Or you can contact [email protected] I guess:
"send an e-mail to [email protected] if you lost access to your account. Support may now remove 2 Step Authentication from your account, aswell as restore your e-mail in case of theft. "
