Problem 1: anyone who touches a weapon of any kind basically turns into a demon controlled monster who wants to kill everyone. Why is that's problem? Well you can't care about characters if they cease to exist the moment they engage in the story.
Problem 2: There are so many characters that have nothing to do with the overarching plot, making the story confusing to follow.
Problem 3: the first rule of writing is: you have to play by the rules of the world you create. These writers just make up rules to fit the moment with no consistency. The world fees very undeveloped because they have no true rules to what the world is.
Problem 4: character motivations are obsurd and they make no sense.
Problem 5: No real good guys. Just people who don't turn evil as fast as others.
Problem 6: the actual plot is completely lost in a bunch of wild and non-sensical scenes that no one cares about.
Problem 7: (petty problem alert) The main character (Gai) is a tiny part of the story. Weird. Why name the show after someone who's almost never in it?
Here's the message of Swordgai - everyone is evil and weapons make them demons. The only not totally evil people are Buddhists who avoid violence. No matter how good someone may be, protecting themselves or others will turn them evil. The end.
