The concept for "Ninja Blade" initially came when From Software tried to create a game that conveyed to the gamer the same intense sequences as those of Hollywood action films. From Software worked with Microsoft in creating the game's protagonist, Ken Ogawa. "Ninja Blade" producer Masanori Takeuchi said: "We worked closely with Microsoft in creating Ken. They provided us with lots of useful feedback and insightful consumer research of worldwide gamers. By cooperating and working together, Ken has become more appealing to a wider audience." The character was designed by Capcom 2nd Character Development Studio designer Keiji Nakaoka.
