As Kaboku Kabo Kotani enrolls in Ichiran High School, he hopes to spend his high school days quietly to avoid standing out from everyone else because of his stuttering. While his friends join the school's basketball club, he looks to the dance club instead. However, due to an embarrassing memory from middle school, Koba has avoided dancing in front of others again, keeping him from joining the club. Things begin to change when Kabo spots his cute classmate Hikari Wanda dancing. As the two learn about each other, Wanda admits that she is not great with words either and prefers to express herself with her performances. This sparks a light in Kabo, and he decides to join the dance club despite his uncomfortable past. With Wanda and his new clubmates supporting him, Kabo sets out to improve his dancing, express himself freely, and create unforgettable memories one step at a time.

Otomo City: where freedom and justice have atrophied to the bone; where conspiracy rules the day and death stalks the night... Death in the form of the Skull Man, a literal Grim Reaper whose skeletal grin presages grisly mayhem and murder, even to the monstrous mutants that haunt the city's underworlds! To investigate a bizarre slaying, journalist Minagami Hayato and photographer Kiriko Mamiya must stalk this ultimate predator, through a festering cadaver of a city where the corruption flows in rivers as deep and foul as the sins of the reigning elite, and unearth a secret so shocking that an entire city has been turned into a tomb to contain! In a nightmarish necropolis where nothing is as it seems, vengeance comes in the form of a living Death's-Head! (Source: Sentai Filmworks)
