Kurai Jikan is a Manga/Manime inspired one-shot scenario for the Austrian NIP'AJIN Roleplaying System. The story is set in a fictitious iron-age Japan where, after 500 years of peace, the Oni (Daemons) return to enslave the people who worship the sun goddess. A dark fog covers the lands and makes travelling very dangerous. A party of heroes - Manga characters with special abilities - are sent by the church to investigate and rescue villagers. They carry with them a small shrine that hold the shining tears of the sun goddess which provide some protection from the fog.
