Hiro was always aware that he wasn't a typical boy, or manly in any regards, and it drove him to find solace in what seemed to be the only thing that listened to him, the flowers and plants in his grandmothers’ shop. When his time in middle school was coming to a close, he started showing off his artistic prowess in flower arranging, noticing more and more that people started coming to the humble shop for him, calling him an amazing and skilled flower arranger. He debuted as a “celebrity” in the artistic side of the community when he began taking on commissions from big names, prestigious institutions, and his skills took him all over the world.
He has quite the social media presence and a huge following on all his accounts, which he is always extremely humble about. Befitting of his general aura and appearance, Hiro is a very passionate and gentle soul, with not much intensity to his nature. As he looks delicate, like a flower, many people underestimate his own willpower, however he has quite a startling amount of determination and confidence for such a slight, small character. He prides himself on being a hardworking member of society, and feels a sense of empowerment when he is able to always put a smile on someone's face with his artistic style.
After careful consideration, Hiro's voice is most similar to that of Chihiro Fujisaki. He does however sound more boyish than the character i'm comparing him to. however other interpretations are welcome!
