Blood-bubble Bushes

Ansai and Kana crash their car. They see that there is blood all over the windscreen, and become worried they hit someone. However, they can't find any carcass in the road. They are stranded in the middle of nowhere and walk around looking for help. They come to a hut full of strange small boys, who won't talk but instead just giggle. Ansai and Kana leave but realize the boys have followed them. They are violently attacked by the boys, who turn out to have mouths full of sharp fangs. Kana is badly wounded and the boys drink her blood.
