How to fetch uncommon records from two tables in mySQL without primary key

I have two tables, both have same number of columns with none of them having any primary key as below:

Table A

Name Ranking Genre Category Rated
M1 1 Comedy Movie G
M2 2 Action Series PG

Table B

Name Ranking Genre Category Rated
MX1 44 Thriller Series G
M2 2 Action Series PG

I need to fetch the uncommon records from both the tables, where Ranking and Name combined is unique for them.

I have tried using left and right join but it gives me all the records from either one table. My priority here is to fetch just the uncommon records as below:

Name Ranking Genre Category Rated
M1 1 Comedy Movie G
MX1 44 Thriller Series G
