An idol under TSUKINO TALENT PRODUCTION. He is a member of the unit VAZZY.

Ouka is a young man of average height with white hair that is short at the back, with long bangs to his chin framing his face, and bangs covering his gray eyes. He is generally seen with a very stern look on his face.

Ouka is first shown to have a very calm and composed personality. He is generally polite and speaks in polite/formal speech when first meeting with strangers and with people in the agency/industry.

In truth, he is actually sharp-tongued and very frank with his words. When first prompted by Mamiya to drop his polite speech, he is not at all hesitant to do so and is quick to change his tone. An aspect that Mamiya found surprising but interesting.
