Kenshin, Unyielding Blade debuts as a limited time character

In the flames of a burning castle, Uesugi Kenshin stood alone. She who had lived most faithfully now faced death, betrayed by her own. For that she felt no regret. To die while believing in others to the very end was a worthy fate. Once, on a battlefield, she took in a war orphan. Taught her the sword, gave her purpose and a name: Miyamoto Musashi. Her lone regret was that she never got the chance to cut down the monster Musashi became. The "sword saint" who ultimately fell to darkness.
