Darkness lurks in the third tapioca boom. A girl who doesn't know what tapioca is is told that it is refined by men and consumed directly.

She is advised to compare the tastes because they differ depending on the man, so she puts it in her mouth and drinks it like juice. When will she realize that it is sperm?
