Ryotaro Okiayu

Ryōtarō Okiayu (置鮎 龍太郎, Okiayu Ryōtarō, born November 17, 1969) is a Japanese voice actor affiliated with Aoni Production. He was born in Kitakyushu, Fukuoka Prefecture, and raised in Osaka, Osaka Prefecture. He stated that he was named after the historical figure, Sakamoto Ryōma, and claims to be "a little technologically illiterate" with the times. Since his family name is considered difficult to pronounce, he is called a variety of nicknames by fellow voice actors during radio shows, interviews, and live events. A few of them include "Ryo-chan", "Okkie", and "Chikiko".

Most people know him better by his typecast "dark and cold" voice for characters in the anime and video game industry, such as his roles for Byakuya Kuchiki (Bleach), Tezuka Kunimitsu (Prince of Tennis), or Gaius (Tales of Xillia). Occasionally he will use his lighter, natural voice to act out cheerful or younger characters. He is a popular voice actor with the female audience, and he has participated in several drama CDs catering to them.

Okiayu has said to have enjoyed acting as Motochika the most out of his Warriors roles and commented to have liked his character's weapon and cool personality. For his role as Sima Shi, he states he can't relate to him personally since his character is a tense, important figure. However, he tried his best for his position and hopes to have performed Sima Shi correctly.
