From what I have seen from Eposode 25 Rito intends to fight his way to Gid Lucione Deviluke in the mothership just to fail the test by saying to him that he loves Haruna.
He Told Rito to "Become the number 1 man in the universe for Lala"
If he does not do that then he has failed and Gid will kill him and destroy the earth.
He is getting help by his friends that believe he is going to save Lala when in fact he plans on confessing his love for Haruna.
The only way out of this situation is for Lala to use Bye-Bye Memory Kun on everyone on earth and start over with Rito and his friends.
