Hikaru Kobe is optimistic, kind and willing to help at any opportunity. With his varied array of musical instruments he can play, he's considered a musical prodigy, able to play nearly any instrument he gets his hands on. He and Tsuki are definitely HPA's cutest couple and they are nearly inseparable. 

Hikaru's voice is mid-range, with an excitable quality to it. Basically a golden retriever if it had a voice. No accent necessary.
