Hiroki is a one-off character from the 1990s Sailor Moon anime, a young inventor set on taking to the skies. His brush with the Sailor Guardians during the SuperS season turns a crashed homemade aircraft into the spark that lets him finally believe his own dream can fly.
Appearance
Hiroki is a boy with cropped brown hair and clear blue eyes.
Personality
A tinkerer at heart, Hiroki lives for flight and invention. He pours himself into building things that can leave the ground, and although an early failure rattles him, encouragement helps him recover his conviction and chase the goal with renewed resolve.
History
Hiroki longs to soar through the air aboard a craft he builds himself. Toward that end he converts his bicycle into a winged contraption he names the St. Louis, but its first trial ends in a crash right in front of Chibiusa and Kyuusuke while the two are out in the park. He and Kyuusuke then join forces to rework the wreck into something that will truly fly, coached along the way by Ami, Makoto, and Rei.
Just as a test run is about to begin, VesVes turns up and strikes at Hiroki to seize his Dream Mirror. Sailor Chibi Moon steps in, which prompts VesVes to summon the Lemures PaoPao Girl, but the rest of the guardians arrive, destroy the Lemures, and drive VesVes off. With his Dream Mirror restored, Hiroki regains faith in his ambitions and helps Kyuusuke complete the machine. Their new model performs flawlessly, and his wish to fly finally comes true.
His surname is written with characters meaning broad or spacious and tree or wood.
