A growing package can have an already running period
A simulcast season is not delivered in the same way as a complete box set. New episodes can arrive while an existing rental continues. The moderator FAQ describes a ninety-day rental and says the relevant date is the purchase, not the final video being added. That makes the transaction date important when deciding how much of a rolling season remains available.
Work backwards from your own transaction
Consider a viewer who rented near the start of a season and returns after the finale. The later episode appearing in the package does not demonstrate a fresh ninety days for all the episodes. Compare the transaction and the account’s current availability before planning a long rewatch. Do not substitute the Japanese broadcast date, the upload date or the day you first noticed the finale for the rental transaction.
Distinguish this from a purchased edition
The same FAQ treats buying and renting as different products, with downloads associated with purchases. A purchased package and a rented package can therefore look similar in a catalogue while having materially different access conditions. Check the receipt’s product type before reporting an expired rental as a missing purchase. Historical shop pages are useful for identifying an old package, but their release names and offers should not be read as today’s seasonal line-up. No transaction or expiry was tested here.
