D_Cide Traumerei the Animation - S01

As a child, Ryuuhei Oda saw his kind older brother die, leaving behind a strange mark near his body. Now a spirited and reckless high school sophomore, he spends his days pursuing his passion for kickboxing. One evening, a bizarre creature bites Ryuuhei’s leg, sending him into a dream filled with unsettling beings. The next day, the same creatures attack him in the real world, but Jessica Clayborn and Aruto Fushibe intervene, insisting Ryuuhei is now part of their team. Under pressure from the looming danger, Jessica tells a bewildered Ryuuhei to become a "knocker-up"-someone who can fight the monsters invading from the dream world. Harnessing his kickboxing skills, Ryuuhei unlocks his powers to protect the city, only to encounter that same haunting mark from his past.
