Go! Go! Ackman

Synopsis

A 200-year-old demon child named Ackman wakes up after a fifty-year nap. His parents explain that they have the mission to kill people and sell their souls to the Dark Lord for money. After his sister Medusa gives him more modern clothes and a sword to replace his trident, Ackman begins to kill people while his faithful Goldon, a red bat-winged creature, gathers the souls in a jar.
