D_Cide Traumerei the Animation - S01

When he was little, Ryuuhei Oda saw his caring older brother die, and near the body he saw a mysterious mark. Now a second-year high school student, the outgoing and impulsive boy spends his days doing what he loves most: kickboxing. One night on his way home, a strange creature bites Ryuuhei's leg and causes him to have a strange dream full of odd beings. When the same creatures attack him the next day in the real world, Jessica Clayborn and Aruto Fushibe come to his rescue, telling him that Ryuuhei is their new recruit. With a threat closing in, Jessica urges a confused Ryuuhei to transform into a "knocker-up," a person able to face the monsters that come from the dreamscape. Using his kickboxing talent to his advantage, Ryuuhei awakens his powers to save the city, only to come across a familiar mark, one he could never forget.
