Tsunenori Aoki previously portrayed a character called Aguri Kusugami (Gai the Sky Knight) in another tokusatsu show, Garo the One Who Shines in the Darkness.

He will now be portraying a new character in Kamen Rider Gaim called Ryoma Sengoku. What’s noteworthy with his surname Sengoku, is that it is spelled just like the Sengoku Driver. He comments that the character is 26 years old, making it the first time he is playing a character that is his own age.
