The sweetest, most lovable seven-year-old girl in the world. While not the brightest bunny in the forest, Mari has a wide-eyed innocence and a love for life that drives everybody at Gilles de Rais elementary absolutely insane.

Sardonic, sarcastic, wise beyond her years and...dead. Kari is the dark Yang to Mari's happy Yin. While she comes off as something of a badass, her one weakness is her love for her sister Mari.

A dead kid who lives in the shed behind Mari and Kari's house. A sweet, thoughtful, super cute kid who also works as a wrangler for doomed souls on their way to hell.
