Sleepless Domain is a comic about an isolated city in the middle of a dangerous world filled with monsters. During the day, the city is perfectly safe. At night, however, the populace locks themselves inside as the city streets fill with monsters. The only ones who can combat these creatures are very special girls with the power to transform into Magical Girls!

Sleepless Domain is dark magical girl comic by Mary Cagle about a lone city that gets attacked by monsters at night. The story follows Undine, a magical girl, who after an encounter with a strange monster, begins to uncover mysteries about the world.

I love the characters of this comic. They are charming and adorable. The art is beautiful as well. Warning, the story does get very dark at times, but that is part of its appeal for me.
