Yūki Rito

The male protagonist of To Love-Ru, Rito is a 16 (currently 17) year-old high-school student. He is the main character in the series, making contact with nearly every major and minor character in the series. He is the object of many girls' affections (which he is oblivious to) but his major crush is on Haruna Sairenji. He is now, however, starting to have feelings for Lala (and maybe for even more girls).

Family
Rito's father, Saibai Yuuki, is a professional mangaka, or manga artist. He is 36 years old and works at somewhere near where Rito and Mikan lives. He is working on three mangas at the same time, and thus, he is constantly trying to meet his deadlines, making only limited time for his family. Despite this, he loves Rito and Mikan very much and sends Rito a monthly allowance (though that is, if he helps him with his manga duties). Rito is constantly running errands for his dad, getting art supplies for him.

Rito mother, Ringo Yuuki, is a fashion designer and scouter. She normally works overseas, where she is very famous. She takes her work very seriously, to the point where as soon as she sees a pretty girl, she starts to size them up with her hands. She is highly perspective, meaning she can read feelings on people's faces.

Mikan
Rito's little sister, Mikan, lives with him in their house that their parents left them at. She usually does all the chores and cooking, with the exception of when she was sick and had to rely on Rito and Lala to do them.

Despite her sometimes rude behavior towards him, Rito cares for his sister very much, and would go out of his way to help her with anything she needs.

Personality
Despite his clumsy nature, Rito is a very compassionate person. He will go out of his way to help a person in need, especially a friend. This trait, combined with his looks, wins over many girls' hearts, especially Haruna, who has been admiring him since Junior High.

Golden Darkness (Yami)
Contrary to her feelings toward him, Rito does not think of Yami as just as an assassin; he thinks of her as a friend. He carries her to Mikado's house when she is weak from using her powers so much. He also tries to save her from another assassin at a festival (which he is unsuccessful at accomplishing). Unbeknownst to him, she may be developing feelings for him. This is supported when he helps her out with chores and makes her coffee when her and Mikan switch bodies for a while (though he did not know that Yami was inside Mikan's body).

Yui Kotegawa
Rito's opinion of Yui is two-sided. On one side, he thinks of her as his friend, especially when she gives him chocolate on Valentine's Day. On the other side, he thinks that she is mad at him all the time because she constantly abuses him for no reason, unware of her feelings for him.

Kyouko Kirisaki
Rito meets the Magical Kyouko character in the Trouble Quest game, but he finally meets the real Kyouko in Chapter 154, when he pretends to be Run's boyfriend for a day. Rito's opinoin of her is that she's just a normal girl; a normal girl that's the star of her own show. They are good friends, despite the little time that tbhey had to know each other.
