Ep. 5: A Date with Kyuu-chan

5

The school goes camping with Marin tricking Chacha into searching for more firewood in the forest. Marine then mixes up the signs, causing Chacha to become lost. She manages to get back home safely with Seravy's help, but ends up being kidnapped, along with Marin, by a vampire who lives in a castle in the forest. They pretend to want to go on a date with the vampire while looking for a way to escape. (Source: Wikipedia)
