This show manages to be awful even with moments of genuine potential. It takes only a single episode to realize how little effort was put into its creation. I initially wondered, perhaps they skipped developing any character backgrounds or crafting dialogue that didn’t feel forced and overly masculine, maybe the appeal lies in the action sequences and animation? I thought I could get on board with something pulpy. That wasn't the case. The fights are monotonous; one combatant delivers a devastating blow, seemingly securing victory, but the other simply gets back up and retaliates with even greater force, only for the first to do the same. This pattern repeats itself several times in each fight. There’s no variety—no special moves, no contrast between speed and strength, no martial arts styles clashing, no consideration of size or weight; it's just damage being exchanged. New characters appear without explanation, each supposedly the most powerful yet, until the following episode introduces someone even stronger, or another random character defeats them. The entire series feels meaningless. It’s a waste of time and best avoided. I might finish watching it while doing chores if an English-language version becomes available...
