Nagi Rokuya

Nagi has blond hair and blue eyes, and commonly describes himself as being "sexy and elegant." Other members of the cast have also described him as beautiful or otherwise very attractive. Nagi is the second tallest member in IDOLiSH7, being shorter than Tamaki by three centimeters.

According to his own comment, Nagi does not have abs.

Nagi has remarkably good looks and high charisma. He is often seen flirting with women and is a great fan of anime. Despite his looks, Nagi was lonely as he didn't have many friends growing up. Due to this, he treasures and loves the members of IDOLiSH7 very much. He is often the one who tries to bring the group together when there is a conflict among the group.

He is also good at fighting and can speak fluently in many languages.

(Note: I’m gonna leave out his family history since it includes a spoiler to Part 4 of the series)

He met Haruki Sakura back in his hometown. Haruki was actually the composer for ZERO, and he had travelled to Northmeir in search of the missing idol.

As Haruki fell ill, he left and disappeared one day entrusting Nagi with the music that he wrote, hoping Nagi will find someone to sing the songs.

Nagi was walking with a friend along an avenue near Takanashi Productions when Otoharu Takanashi called out to him. His friend was cautious towards Otoharu, but Nagi wanted to hear what he had to say and was thus scouted. Nagi originally came to Japan to hand over Sakura Haruki’s songs to Takanashi Productions, as suggested by Sakura Haruki in his letter. Nagi was in the neighborhood because he wanted to see for himself what Otoharu was like before he anonymously sent him the songs.
