Yamadera is known to have a wide vocal range and is sometimes known as Shichishoku no Koe wo Motsu Otoko (The Man Who Has the Voice of Seven Colors). The majority of characters he plays are comedic, cool or heroic.
Kouichi: Of all the stuff Mr. Matsumoto's done, I think this is the most difficult(the original work on "Harlock Saga"). There were moments when I was left going "Huh?", but I think it's a really cool story. In the many times I've spoken with him directly, I've seen how his attitude is so forward-looking. He has so many things to tell about this world today. Dreams, hopes, romance... And the scale of the story is so huge. I don't think anyone else has told a story of this scale before.
Kouichi: In any case, enjoy the show (Harlock Saga). I hope that this story of immense scale transcends the ages, so guard it well for future generations to enjoy.
