Hideki Ryuga

' Hideki Ryuga' (流河 旱樹, Ryūga Hideki) is a Japanese pop-star and actor who stars in his own television show.

Plot
Initially, Ryuga is only seen on TV in a show that Sayu Yagami watches, Sayu seems to be a big fan of Ryuga, as shown when she complains at Light Yagami when he suggests she change the channel while Ryuga was on. Later, when L decides to reveal himself to Light at the To-Oh University entrance ceremony, he uses Ryuga's name as an alias.

L's reason for using Ryuga's name is revealed by Light to not be just an alias, but also a trap, because if Light were to risk writing the alias into the Death Note to test the name, he might accidentally picture the real Ryuga's face and end up killing the star instead.

Ryuga himself eventually has an actual, albeit brief, appearance in the main story when Misa Amane lands a role as his love interest in a movie. While filming a scene where Ryuga is supposed to kiss her, Misa protests, refusing to kiss him due to her uncompromising faithfulness to Light, much to the frustration of the director.

His last appearance is at Pop Music Festival, presented by Kiyomi Takada. He appears along with other members of the cast of his upcoming show, "Ryouma Sakamoto" (in which he will be playing the title character, Ryouma), including Ami Hamazaki, who will be playing his love interest.
