It seems a little odd that someone young and book obsessed like Hikaru would be hosting a lemonade stand, doesn't it? But she does, for a couple goodcauses in fact! Her lemonade is completely home made and she only adds a little bit of extra sugar to sweeten it up to keep the natural taste nature offers with this rather unique fruit. All of the money Hikaru makes is either donated to the Library so they can purchase more books or she saves it to help people out on the street that aren't nearly as fortunate as her.
