Ace’s Voice Actor Yamashita Seiichiro

Ace’s VA Yamashita Seiichirou wanted to be an actor, but says there weren’t any opportunities in his home of Hiroshima. He became interested in voice acting after starting high school and making friends who introduced him to manga and anime. ( Interview Source )

After high school he enrolled in Tokyo’s Amusement Media Academy. He was accepted to talent agency Office Osawa in 2013 and made his anime debut in October of that year as Mizuno Takahiro in “Walkure Romanze.”

On the topic of Twst Yamashita has often said that his personality is actually more similar to that of Deuce, such as this interview from the 2020 fanbook (vol.1).
