The battle ends with a great, hefty boom and a flash of light. The two of them sag against each other and watch the end, watch their Digimon collapse into piles, watch the monster disperse into pixels and look at the thing staring at them without eyes. Sayo looks at it so sadly. It's as though she's forgiven him for awful thoughts and attempted murder.
It just floats in their general direction. Then it vanishes slowly, wishing vainly for someone who Koh has never heard of before.
Sayo's head lolls on her shoulders, slumping on his neck. Koh shakes her gently with the tips of his fingers. When she doesn't respond, he takes a moment to breathe and not scream and picks her up with aching limbs. He keeps walking. The Digimon trail after until he stumbles through shoving twelve of them in his Digivice. She doesn't stir at all.
Koh doesn't think she's breathing.
