this movie has quite a number of surprises, even after being formulaic. first, the battle and fighting sequence proceeds and gets conducted the way it usually does. initially they aren't successful, then in the 2nd bout they are. they succeeded in showing Kuwabara as a more of a useful character. then in the last fight, central fight, they all literally win with the power of friendship, combining all their powers. this combination was nice to see. then the villain needed a finishing blow. canonically i think this side quest should take place in-between chapter dark tournament and chapter black. that way i guess it wouldbe explained how the guy escaped from his seal, as many souls during dark torunament, but it still doesn't make sense. Anyway, plot is, bad guy comes wants to threten the status quo, yada yada yada. And as always our foursome guardians, as usual, have to dedicate their energy to protect the system, to not let home ground lose.
