To Love Ru s02e12
Titre original : I Love You♡ 1
Starting from where Episode 11 left off, Lala accepts Haruna's feelings and vows to help her have her own relationship with Rito. At the water park, Yami is less violent towards Rito than normal and Haruna and Lala are noticeably closer. Yui is flustered at being around Rito in her bikini. Saruyama observes Rito and tells him that he has changed after Lala came around as Rito is more comfortable being with girls. Rito tries to understand the values of Lala.
Nearby, Run and Kyouko perform a concert when an alien amoeba attacks and suffocates everyone. Lala tries to rescue Haruna, who gets eaten by the amoeba, but suffocates. Rito sacrifices himself to rescue Lala and Haruna. As Haruna and Lala try to rescue Rito from death, Rito sees flashbacks and realizes that he loves Lala too.
After the amoeba was defeated by Yami and Lala, Rito tells Lala in private that he loves her, but loves Haruna too. Lala happily proposes that Rito marry both of them. Peke says, "Since the marriage between Rito-Dono and Lala-Sama will make him the king of universe earth rules won't matter anymore". Before Rito could oppose, Lala pushes Rito towards Haruna so he could confess to her too. Oshizu accidentally rips Haruna's swimsuit, making her run away before Rito confesses to her. His confession is instead accidentally directed to Nana, Yui, Mikado-sensei, and Run, inspiring Lala to happily suggest that Rito should marry all the girls and then they can all stay together.
