浪川大輔
Yu's voice acting has been handled by Daisuke Namikawa in Japanese. Besides the game, Namikawa voiced the character in a drama CD before the anime's premiere. He considered Yu as a honest young man. However, he felt the Yu from the game and the anime to be completely different based on the directions he was given to act. In retrospective, Namikawa finds his work interesting due to the amount of actors he worked with. Since Narukami was a silent character in the video game, the actor felt his portrayal in the anime more challenging, and thus had to act more. He took a liking to both Yu's daily life as well as his fights in the TV World.
