If Sukasa didn't tell you already, Twin Egde is a two part game, Kaitenshin's Path and Sukasa's Story. Both games come from the perspective of two different characters, that join together, but are then split apart.
Story Basics: The world was at war for a long era of time untill the gods sent down Eight beings (the Yatsu Boushi; Eight Eyes) to settle the disturbance. But, it didn't take long for the Yatsu to take advantage of the situation, and wage war. Yet, there was one Yatsu, who took it upon himself to stay true to his real purpose. This being had slain every one of his bretheren and had sealed them within temples in each land. Generations have past since then, but terrible rumors are arising of a new war that will shatter the peace that has lasted for centuries, and crush all who are involved.
Play as Ashiza Kaitenshin, discover your terrifying past, and unleash the abilities granted to you by the gods themselves.
Play as Shikaku Sukasa, and avenge your bloody betrayal, find your true purpose, and slay the ones who have destroyed the most valuable thing you once had.
Alliances and friendships are put to the test, as you battle through an era of chaos that will change the true meaning of life and death, for the rest of eternity.
I'll post up some screenies of Kaitenshin's Path soon, and might I ad, I think I have better maps then Sukasa's story.
