Just when you thought it couldn't get any stranger, Excel Excel and her associates encounter the most horrifying of all plot devices...a sub-plot! You won't believe who's been plotting against whom as the writers double cross the author, the director takes a new direction, and the supporting cast comes back with a vengeance but absolutely no clue whatsoever! There's Menchi-mania and Pedro-philia galore as everybody involved takes the fifth in 'Excel Saga: Vol. 5'! Contains Episodes 18-21.
