Yūki Rito

Rito Yuuki is the main protagonist of To Love-Ru. He is a normal 16 year old student of Sainan High, and he has a big crush on Haruna Sairenji. He attempted numerous times to confess to her but has met with failure each time. Rito used to be on the soccer team in junior high and was quite good, but quit because he was constantly helping his father with his mangaka duties, thus did not want to leave his little sister Mikan Yuuki alone in the house. Mikan comments he is very good at the most "useless little things", like crane and festival games (e.g. hoops, catching fish, squirt guns). Along with the numerous useless little things Rito is good at, he is also an accomplished florist, gardener, and horticulturalist.

Rito's nature is borderline clumsy, where he always ends up ogling or groping the many girls in the series (though mostly unintentionally). It is only by accident that he encounters and despite his enduring feelings for Haruna, Rito shows signs of developing deeper affection towards Lala a troublesome character that at first pretends to show affectionate feelings for Rito Yuki through the beggining of the story. As the story progresses he starts to show affection for Lala but is unsure if what he feels is actually love. This is shown again when he couldn't help but think about Lala even though he was with a naked Haruna. It is recently revealed that he is in love with Lala, but he is also in love with Haruna. At the end of the series, he confesses to Lala, but tells her he also loves Haruna, yet she is happy on both parts. He is confused as polygamy is illegal in Japan where Lala replied that once he is king of the universe the laws of earth no longer apply and forces him to go tell Haruna (strapping a jet pack to his back). Right before he was about to tell her, she moves out of the way, just like when he confessed to her very early in the series, leading him to state "I love you" to all of the female cast with the exception of Momo, Mikan, Golden Darkness, and Haruna herself. The ending implies that his "love" troubles will continue on into the future.

Relationships with Other Characters
Lala Satalin Deviluke 

Rito first met Lala in the first episode of the series when she teleported into his bathtub while running away from home. At first Rito wanted nothing to do with her, even saying that he didn't like her." But as the series progresses, he became very good friends with Lala, and even falling for her romantically all thus Lala attempts to subdue rito with her "Naked body" most naturally making Rito run away in a frantic manner.

And many points Rito is willing to risk his well-being for Lala. One specific time, Black, a hit man, pointed a gun at Lala, Rito stood in front of Lala, refusing to move.

At the end of the original series, Rito confesses his love to Lala, while also telling her that he loves Haruna as well. Lala is ecstatic about this however, noting that once their marriage is official, Earth laws will no longer matter, and he will be free to marry both Lala and Haruna. Rito is shocked by this, stating that Lala is "to open minded (Chapter 162)."

In the spin-off To Love Ru Darkness, Rito still loves both Haruna and Lala, while his main objective is confess his love to Haruna, he does show his love for Lala, after he found out how compassionate she is, he started feeling nervous and she went to check his temperature. Being so close, Rito's heart racing caused him to run away, naturally leading to an ecchi moment between him and Lala (Chapter 10).

As it progresses, Rito considers Lala and Momo's Harem idea; however, he quickly shakes it off.
