Sairenji Haruna

Haruna Sairenji is the second female protagonist of To Love-Ru, the first being Lala Satalin Deviluke. She is in the same class and same classroom as Rito Yuuki, and is the object of his affections. She has the same feelings for him (possibly even greater feelings), but her somewhat timid personality and Lala's presence prevents her from confessing her love for him.

Family
There is not a lot of information on Haruna's family.

Haruna lives with her sister, Akiho. Their mother and father used to live with them together, but because of work, their father had to move, and the mother went with him because he would worry.

Akiho apparently has a job working somewhere (according to Chapter 146).

Personality
Though Haruna has friends, she has a timid and shy personality, especially when it comes to being around Rito. She is terrified of ghosts, excluding Oshizu.

Haruna has a habit of grabbing something near her and swining it wildly when she sees something that she is afraid of. Usually, the thing that she swings is Rito, causing him much pain.

Rito Yuuki
Haruna is deeply in love with Rito starting from their time at middle school together where she recognized his gentle nature. After the appearance of Lala, Haruna became somewhat subdued with thoughts over the two's relationship and later resolves with much effort to congratulate him over it.

Haruna has a habit of ending up in in rather lewd situations with both Rito and Lala. These situations revolve around either Rito and/or Lala appearing naked infront of her or, as has become more common, Haruna getting tangled up with Rito in highly compromising positions (His hands ending up on her breasts, butt or croach or within her panties). Her reaction is usually the same involving her becoming shocked and slapping Rito before running away. In most cases, she is quick to forgive Rito for this and the next time they meet she does not mention it.

After discovering the truth about Lala and subsequantly their relationship, she becomes more hopeful over having a relationship of her own with Rito. However her growing friendship with Lala makes her feel guilty over her love for Rito, who Lala also loves. Haruna eventually gains the courage to tell Lala that she has feelings for Rito to relieve her guilt and after a short while the two (notably Lala) agree to become friendly rivals for Rito's heart. The two even make chocolates for him together on Valentine's day.

More recently, Haruna has been trying (unsuccessfully) to confess to Rito mostly by hinting at her affection for him. The most noticeable of which is when she and Rito became trapped naked together and after a few accidentle groppings from Rito and Haruna herself accidentaly jumping on him, she confides in him about why she lives with her sister and he confides in her about his parents. She admits to him that she would like to be with someone to mutually depend on and looks at Rito hopefully. Rito even seems to get the hint to some level and is about to say something but is stopped both by an image of Lala in his head and by Mikado finding them.

Lala Satalin Deviluke
At the beginning of the story Haruna had the opinion that Lala and Rito were a couple and that fact saddened her. But after a while she was able to overcome it and became good friends with Lala, even to the point that she feels guilty over her own feelings for Rito. She eventually develops the courage to tell Lala that they are in love with the same man, which after a while, Lala grows to accept and declares that they are now friendly rivals for Rito's heart. The best example of this is on Valentine's day when both Lala and Haruna made a joint bag of chocolates for him.

Despite their good relationship, Haruna has admitted to feeling jealous of Lala's position living with Rito.

Oshizu Murusame
Contrary to her fear of ghosts (or anything relating to ghosts and spirits), Haruna and Oshizu are very good friends, and are seen with each other alot. Haruna warmed up to her when Oshizu received an artificial body made by Mikado. Oshizu knows that Haruna loves Rito, and continuously pushes her to tell him her feelings.

Risa Momioka
Haruna has been good friends with Risa and Mio since the beginning of the series. Most of the time Risa is seen groping Haruna's chest.
