Our story is set in another world, parallel to ours. We meet Pastel, an orphan girl, 18 years old, who lives with a group of adventurers in a small house. Pastel works as a writer and also a "mapper", charting towns, the countryside, rivers and mountains with sketches and illustrations. She is highly respected by her friends as her intelligence and honesty are extraordinary. (myanimelist.net)

Sumimura Yoshimori is a normal 14-year-old middle-school student, though he always falls asleep in class. This is however due to his night duties, in which he takes on the role of a Kekkaishi (Barrier Master). Together with Yukimura Tokine, his neighbour and childhood friend (/sweetheart), he serves as a protector for the school which holds a few ancient secrets. These secrets are slowly being unraveled, which may play a role in Yoshimori's ultimate plans. (anidb)
