If you wish to transfer your .RU domain away from Hostinger you will need to do a few things:
Make sure that your domain email is verified
Make sure you have access to your email account used when registering the domain
Be prepared to provide your ID/Passport photos (if needed)
Due to the nature of .RU domains, EPP code cannot be shown on hPanel. For this reason, when you do all the things mentioned above, you can freely write to our Customer Success team, and we will help you out with transferring your .RU domain to another provider.
