Hiroshi is a tall man with a muscular build and like his dôji, he has very hard facial features. Whenever he is angry or excited, his veins visibly pop out of the sides of his face. His facial features also consist of a shaved head, sunglasses, and two visible scars - one on the right side of his mouth, ending at the base of his chin, and the other next to his left eyebrow. He wears a light-colored jacket with a t-shirt underneath, sweatpants, and sneakers. He is shown to have many tattoos covering much of his arms and torso when he rolls up his jacket sleeves or when in ICON mode.
After his battle with Vice, he neck was broken and can no longer move from the neck down, resulting in him having to be in a wheelchair, He wears bandages wrapped around his upper body, covered by a white t-shirt and a polka dot blanket covering his legs.
Contrary to his "occupation" of being a punk, Hiroshi is quite passive and rarely talks, mostly appearing calm and collected like his dôji. However, he become rather very aggressive when anger and is quite threatening towards people who are slow, such as Yamato Agari.
Upon his second meeting (after Yamato rewinds time) with Yamato, he show to be respectful and cordial to his boss, Hyoe Tokorozawa, and Yamato himself. Hiroshi believes wounds are badges of honor and refused to let Pardonner heal him. Loyal to the Hyottoko Gang, Hiroshi dedicated himself to teaching his underlings after receiving his injuries.
They are shown together in all of their appearances, and possible dating each other. Aside from their a spat over the casually used of his name in Chapter 8, Hiroshi respectfully talks and often agrees with her. When Hiroshi was recovering in the hospital, Machi was seen to be the one pushing and operating his wheelchair for him.
