Dreamtaker (Omori x Helltaker)

Sunny had to get Mari back, and after four years he had found a way. A gateway to Hell via which he could recover her soul and return her to life. After opening this portal he meets many demons, who, for various reasons, take Sunny under their wing. Each with their own reasons for burning and each seeking to become better than they once were. Mari returns to life as well, but such things are not without price and sooner or later...

The truth of how she actually died will come to light...
