branding word when a new site is created

how do I remove this from my admin dashboard the branding word. So for example I was able to take out the tools tab by using this code <?php
function custom_menu_page_removing() {
remove_menu_page( 'tools.php' );
}
add_action( 'admin_menu', 'custom_menu_page_removing' );
?>

I would like to take this tab when a user create a site. I don't want the plugin to stop working I just want the user who creates a site not to see the name branding.
