Sairenji Haruna

Haruna Sairenji is the second female protagonist of To Love Ru and one of Rito's classmates and the girl of his affections. Haruna has similar feelings for him, having been attracted to his kind, gentle nature since junior high. Despite her growing love for Rito, which she believes to be unrequited, she usually suppresses her feelings and cannot confess to him because of her friendship with Lala who also loves Rito. However, with some encouragement, she tells Lala of her ordeal, to which Lala accepts, claiming Haruna as her rival for Rito's heart, while remaining friends.

In the anime, there is a running gag where Rito is about to confess to her, only for something (or someone) to come between them.

Haruna is affiliated with the tennis club and a southpaw.

Appearance
Haruna has blue hair and blue eyes, she has quite a cute complexion which most boys seem to like. She always wears a hair clip on her hair where ever she goes, mostly a red one.

According to Mio Sawada, Haruna's measurements are B79, W56, H82. Despite having a fairly normal physique for a girl her age, she often feels inferior being surrounded by girls like Lala and Yui who are, far more developed.

Personality
A highly responsible person, Haruna's personality can sway her classmates' hearts to vote for her as their class representative, even when she did not run as a candidate, she has also shown to have great leadership and is able to keep everyone calm when they are panicking.

Haruna can also be a very kind, understanding and patient person, an example of this is when she's is genuinely polite to everyone around her, especially to Rito. Despite his perverted clumsiness, she always manages to forgive him whether he pants' her or gropes her boobs (those of which are by accident), but she does occasionally slaps him for it, although she is fully aware that he doesn't do it on purpose.

In the beginning, she has had feelings for Rito, but has hardly shown any expression of them until he stared hanging out with Lala, to which she started showing a bit of jealousy, although they did became good friends. Secretly she enjoys Rito's kindness, like when she was turned into a cat by one of Lala's inventions, he found her (unaware that it was Haruna) and started playing with her, which she claims it's like being in heaven and didn't mind being his pet, but quickly shakes it off (To-LOVE-Ru Darkness Chapter 13.5). Another example is when she was drunk off Deviluke herbs, she couldn't help but cling on to Rito (half naked and wet) and says that he's all hers for the moment (To-LOVE-Ru Darkness Chapter 26).

She has a severe fear of ghosts and the supernatural with the exception being Oshizu Murasame, but only for a while. When frightened, she has a habit of grabbing the nearest thing around her – typically Rito – and swinging wildly, in an attempt to get rid of whatever frightens her.

Powers and Abilities
Even though she seems shy and weak, she has more strength in her than everyone thinks, which is occasionally revealed rather comically. Her strength is often shown when she is frightened of something, and she becomes capable of lifting, swinging and throwing an actual person (mainly Rito) and knocking back the thing she's scared of.

Haruna is quite skilled in tennis. She is also good at improvising, like when she and her friends were inside the virtual reality game Trouble Quest, she skillfully used a sword, comparing it to how she uses a tennis racket.
