Dream Eater Merry (夢喰いメリー, Yumekui Merī) is a Japanese manga series written and illustrated by Yoshitaka Ushiki.

The boss of the cat army, John Doe, tells him that his body is needed to access the real world.

In the meantime, a mysterious boy named Kyou Shiragi transfers to Yumeji's class, where dream demons are suddenly manifesting; as a result of their losses, they cause humans to accomplish their goals instead of destroying them.

During the school cultural festival, a powerful dream demon in the form of Kyou and his minions attempts to disturb the balance of both worlds.

The pair and their companions fought together to send the adversaries back through the doorway, repairing it, and everything the dream demons have touched becomes undone.

[5] The opening theme for the anime is "Daydream Syndrome" by Marina Fujiwara while the ending is "Yume to Kibou to Ashita no Atashi" (ユメとキボーとアシタのアタシ, "Dreams and Hopes and the Me of Tomorrow") by Ayane Sakura.

"[13] Gia Manry compares Yumekui Merry to a poor man's Soul Eater with its definite sense of style over substance.
