Trying to defend the Ash Castle was a losing strategy.
They could potentially deal with the three Snow Beasts, but that would take time. And in that time, more powerful figures would most likely reach the Ash Castle, leading to a checkmate.
Sunny had grown used to dealing with problems by using overwhelming strength as of late. But here in Ariel's game, he was once again weak — he did not have his shades, his Shadows, his Memories. He did not even have a single shadow to augment himself.

"So, what should we do?"
Kai shrugged.
"The same thing Ki Song did at Greater Crossing, I guess. Abandon the fortified position and attack instead, aiming to crush the enemy forces while they are isolated from each other."
