design suggestions for apprentice

I am working in a database project that involves the following.

table admins <--------relation one to many ------ table accounts

The people belonging to the table admins can create accounts, delete accounts, or modify accounts.

Now, there is supposed to be ONLY one super_admin that is going to administrate the admins (create, modify, delete)

I am thinking in just creating a new relation like this:

table super_admin <---------- relation one to many ------- admins

But is it worth it to create a table just to have one record on it (the only super_admin).
Or is there any other more efficient way to to this???

Thanks for your input.
