Jewel BEM Hunter Lime

A twelve episode series of short, low-interaction semi-animated episodic games by Silence. The series tell the story of Bass and Lime, two demonic creatures who assume human form and travel to Earth in order to retrieve stolen jewels from "big-eyed monsters" (BEMs). The anime Jewel BEM Hunter Lime is based on these games.

Once upon a month, a door behind the full moon opens. This door is between the human world and magical world. Now it just so happens that on one such night, Lime and Bass are in hot pursuit of a demon who had stolen six power gems from the magical world. The demon escapes to the human world through the open door, and the two follow. Now they must search for the six power gems, all of which have been scattered all over Tokyo. It's up to Lime and Bass to blend into with humans and find the gems.
