I don't currently have Netflix, the series is apparently not available on Crunchyroll in my country. What other ways are there? Are there other official portals that are legal?
Paid: Netflix (season 1 and 2), Wakanim (season 1 and 2)
Free: Wakanim (season 3 Alizization and war of underworld)
You could watch it on Amazon video!
