If you're looking for anime similar to Prayers, you might like these titles.
In Japan, there is a disturbing rumor being spread that people's shadows are ripping from their bodies, never to be seen again. For one young man, the frightening nature of this rumor is just beginning to manifest in the form of a nightmarish world that he can't seem to escape from. In this place full of dark minions and demons, he and his friends fight futilely against unknown enemies, only to be brought back to the "real world" as quickly as they left it. Is this real, or a dream? Only one person holds the key to destroying and saving the world as he knows it...
This is going to be one of those recommendation pairs from me that you'd just need to trust. Though they don't seem to have anything in common, I'm just fairly certain if you liked either Interlude or Prayers, that you'd like the other. Maybe its the dark plot, or the apocalyptic-looking art. Maybe it's the character designs, or the gritty monsters. Who knows? Regardless, if you like one of these I'm pretty sure you'd like the other.

In the world of tomorrow… when technology has reached it limits… a group of young cyborgs must battle the extra-dimensional monster girls for final control of the enigmatic force known only as…The Mystery Frequency!
Legendary rap group The Dirty Dawg could have taken Japan by storm, but they broke up before they could. Now each member has joined one of four rival groups—fighting for the territories Ikebukuro, Yokohama, Shibuya, and Shinjuku. Battles for turf are fought with Hypnosis Mics. These special microphones have the power to affect the human spirit, and people now use rap to determine superiority.
Inspired by house music from a young age, Yukiya spends his free time as a DJ for a crowd of one and uploads his videos online. Like any young teenager, he yearns for something greater than his current life. He wants recognition and importance, but breaking out of his comfort zone means he runs the risk of getting hurt, so the cycle continues. That is, until the day he crosses the line of no return and stumbles across a mysterious live broadcast that will change his world forever.
