Hanazono, Hakari

花園羽香里

One of Rentarou Aijou's first two girlfriends, along with Karane Inda. She is a first-year student at Ohana-no-mitsu University High School, in class 1-4.
Hakari is well-mannered, academically brilliant, and comes from a wealthy family. She also has an alluring figure, with a large bust (of which she is very proud). She is considered a deredere (デレデレ), as she is open and affectionate with her feelings towards Rentarou. Hakari is also extremely lewd, and often comes up with various schemes to help herself or her co-girlfriends get closer with their shared boyfriend.
Hakari meets Rentarou (and Karane) on their first day of school, when they bump into each other in the corridor. After attempting to get closer to him by faking an injury, the two of them hear about a rumor about the pink clovers in the schoolyard and romantic success, and they rush off to find one.

Spoiler

Besides Rentarou, Hakari is also extremely close with her co-girlfriend Karane. They spend a lot of time together, and they have also kissed each other both unconsciously and of their own volition.
Name/Birthday Pun Explanation:
Hanazono (花園) means "flower garden". This is a reference to the phrase "頭がお花畑" (atama ga ohanabatake). It literally means "having a flower garden in one's head", and is used to describe someone whose mind is usually filled with fantasies and illusions.
Hakari (羽香里) is a homophone of the Japanese word for "to scheme" (図る, hakaru).
Hakari's birthday is June 22nd. This is because the digits in her birthday, 622, can also be read as むふふ (mufufu), which is how she laughs in the series.
