repost9ing what i said earlier about this
theres a whole history of modern kabuki vs traditional kabuki that [sandman] is ignoring. plays can have any number of acts, but the most famous kabuki plays in japanese history all tend to be 5 or more acts. THESE DAYS, in the 2020s and earlier, kabuki in japan is almost always 3-4 acts, because audiences don't have the attention span for the older plays, so they run abridged best-of versions of historical plays and write modern kabuki shorter. but wano is based on traditional kabuki, and ancient japan. it's not going to be 3.
in the past? there are kabuki plays that are 18 acts long and meant to be watched over several days. you're lucky wano is only going to be 5. the "Three Kabuki Greats" that Oda is taking inspiration from for this arc,
Yoshitsune Senbon Zakura, (About the fall of a mighty clan and the corrupt rulers that take over, has a lot of double identities, denjiro's three identities and the monk who turns into a fox come from this play)
Kanadehon Chushingura, (the 47 ronin who get revenge for their murdered master and throw their own lives away in the process, like the scabbards are doing for Oden), and
Sugawara Denju Tenarai Kagami (a man murders his own son instead of the child he's obligated to kill, to save the other kid and ensure the future of the country, possibly kaido will kill yamato?) are all at least 5 acts long, with Kanadehon Chushingura being 11 acts long.
Considering the most inspiration has been taken from 47 Ronin and the samurai's revenge is the main focus of the wano arc, perhaps we should be predicting 11 acts for Wano.
