>>6303897akina membership can be hit and miss, and i say this as an akina gachioshi. there are times when he uploads rarely, and times when he uploads around weekly. depends, i feel like, on how menhera he's being and if he wants to hide behind member paywall because he seems to assume members are more accepting of who he is because they like him enough to pay for it.
that being said, he's usually a lot more open on mengen (for instance, in recent ones he talked at length about what members he shipped in oofuri, openly being disappointed about not participating in the vr concert, being a pervert over kemoshota, etc.) so it's really enjoyable if you want to get to know him more in a place he isn't always keeping up his super genki facade. he also does more experimental stuff that he'd otherwise be shy about (utawaku he's embarrassed about, gartic phone since his drawing skills were uh... something else lol), and reveals a lot of stuff early (collabs, upcoming songs) so if you really like akina and the price is worth it no matter how much he's uploading i recommend it.
