Katsuhiro Harada (Harada_TEKKEN) is a producer from Namco Bandai. He is best known as the producer of both the Soul series and Tekken series.
He makes an appearance in Soulcalibur V as a bonus character in a Quick Battle challenge. He uses the Character Creation exclusive Devil Jin style, which derives from the character Devil Jin from the Tekken franchise.
Harada maintains a fairly active Twitter account .
His theme music is that of the Cathedral stage from Tekken 5.
He uses the Cold Assassin voiceset from the character creation.
Harada's costume in the character creation highly resembles the clothing of Heihachi Mishima from the Tekken series. Also, Heihachi Mishima is Harada's favorite Tekken character.
Strangely, Harada's thumbnail shows him having a sleevless gi (possibly the Spy Robe colored black) but in battle he has a longsleeved gi. The same happens with other Quick Battle opponents having different weapons in their thumbnail and in battle.
Beating him in Quick Battle will unlock the "Pursuit of Obsession" Trophy/Achievement.
