Hikaru grew up with his father as a talented aerobatic flier, having won seven amateur flying contests by the age of 16 in 2009. When his "senpai" Roy Focker invited him to the launch ceremony of the SDF-1 Macross he found himself pulled into a galactic war against an alien race called the Zentradi. He later joins the UN Spacy after a talk with Focker and Lynn Minmay. Shortly after joining, he gains a reputation as a skilled pilot and leader, and he is promoted to second lieutenant and later first lieutenant. He pilots the VF-1S Valkyrie "Skull One"
and is eventually promoted to captain at the end of the series. Hikaru is an atypical anime sci-fi hero. Despite some early personality clashes with his female superior officer Misa Hayase, Hikaru is a rather humble and jovial type of person, in contrast to the usual hot-headed type of heroes of other mecha series. He displays leadership abilities early on and has a deep sense of responsibility and duty. However, unlike most lead characters, he concedes that his subordinate, Maximilian Jenius, is the best in battle.
