Hoshino in Ultraman THE FIRST

Unlike his original counterpart, he only appeared in the first chapter of the manga. He arrived in the control room comforting Akiko Fuji, who believed Hayata was presumably killed, until Hayata contacted her.



  • Following the 25th episode, Hoshino no longer showed up for the rest of the series due to his actor, Akihide Tsuzawa, suffered a leg injury during an accident involving skiing.
