After the festival battle, Taro and Yumi question Izumi about her mysterious involvement. She coyly deflects at first.
Meanwhile, Sota helps the crowd and finds a strange artifact - an ancient riddle about "Twelve who became Two." Could it relate to their foes?
Consulting his sources, the Tengu spy Heisuke arrives with grim news. The samurai clans have united all Twelve Bloodlines against Taro once more.
Frustrated at the lack of answers, Taro decides to pay a visit to Izumi at her run-down family dojo. There, she reluctantly shares her clan's dark history with the Twelve.
Thanks to Sota's discovery and Izumi's testimony, new clues seem to link her ancestors with the betrayal that weakened Taro long ago.
But before they can discern the full truth, the samurai attack in force, seemingly led by a powerful new enemy. Taro and allies must bands together once more to face this threat!
