Akira is famous for his many roles, including Ultra Masked Man, the hero of a popular sunday morning cartoon. Although he is the son of Arisa Hoshi, a former famous actress, he is not considered by her to have inherited his mother's talent. Conscious of his perception by many as "not a worthy successor to his mother", Akira intends on proving himself as a real actor.
Akira has short blonde hair, in a messy style. His eyes are blue and he is 173 centimeters tall. Akira's casual outfit is a light blue v-neck collared shirt, which he wears when not performing.
When performing in "Death Island", Akira's costume is the standard school uniform used in the film, with a shirt and tie, as well as plaid pants.
When performing in "Night on the Galactic Railroad", Akira's costume includes a black suit, turtleneck, and his hair is brushed in a different style.
From a young age, Akira was able to become a child star. He thought it was because of his own skill, but soon realized his success was only due to the influence of his mother. At the age of 10, Akira tried to overcome this by studying advanced acting for several days, but could not follow through. He grew up to be a star, but his inferiority complex and feeling of emptiness towards his acting remained.
