Description
Nagi Rokuya, a member of IDOLiSH7, is half-Japanese and half-Northmarean, born as Nagi Valhart von Northmeir, the second prince of the fictional Northern European country Northmarea. His elder brother is Seto Ranvalt von Northmeir, and Nagi's royal lineage is initially kept secret.

Before joining the group, Nagi lived in Northmarea. There, he met composer Haruki Sakura, who was searching for the missing idol Zero and had composed songs for him. Falling ill, Haruki entrusted his compositions to Nagi, hoping he would find someone worthy to perform them. Haruki suggested delivering the songs anonymously to Takanashi Productions in Japan via letter.

Nagi traveled to Japan primarily to deliver the songs. Near the agency, he encountered Otoharu Takanashi with a friend. Ignoring his friend's caution, Nagi engaged Otoharu, leading to his scouting and inclusion in the newly formed IDOLiSH7. His motivation evolved into seeking connection and belonging within the group.

Nagi exhibits high confidence in his "sexy and elegant" appearance and frequently flirts indiscriminately with women, though he has never dated. This charisma contrasts with social awkwardness stemming from past loneliness and difficulty making friends, making the group members precious to him. He actively mediates conflicts to maintain group cohesion.

His notable habits include insisting on hugging each member before sleeping, seeking them out if necessary. He sometimes deliberately touches Iori Izumi's butt during hugs to provoke a reaction. Nagi is terrified of ghost stories; after jokingly requesting "chilling stories" from Sogo Osaka, Sogo began nightly readings of "100 Ghost Stories," which Nagi feels compelled to endure due to a superstition about stopping prematurely causing misfortune.

He is deeply passionate about Japanese pop culture, especially anime. His favorite series is Mahou Shoujo Magical★Kokona, and his room is filled with merchandise. This passion sometimes conflicts with his duties, like considering skipping an outdoor festival for a limited-edition Cocona body pillow event. Nagi is highly intelligent and fluent in eight languages: Northmarean, English, German, Norwegian, French, Italian, Japanese, and Chinese. However, he initially struggled with practical life skills, having never prepared food before moving into the IDOLiSH7 dorm.

Nagi harbors a significant grudge against the World Government and the figure Imu, linked to witnessing Cobra's death and learning of Imu's plan to destroy Northmarea and his family. This influences occasional displays of formal princely demeanor, notably surprising his groupmates around Princess Vivi of Alabasta. His royal background surfaces in his actions and motivations.

Physically, Nagi has blonde hair, blue eyes, and is 180 cm tall. He dislikes Japan's summer heat and receiving injections. His interests include anime and games. He represents the number six within IDOLiSH7, and his musical symbol is a natural sign.

Nagi's development involves transitioning from a lonely prince seeking purpose to a cherished member of IDOLiSH7 who finds genuine friendship and a platform for his passions. His journey includes reconciling his royal identity with his idol persona and confronting external threats to his homeland.
