To give full transparency here, I have always liked to charge 5$ per month for my stuff, When I made this page 5$ (Before Pixiv+Paypal Fees) was about 600~yen, And I was totally okay with that; Now, Because of some economy shenanigans outside of my knowledge, The Yen is worth less than it was before, So right now 600yen is about 3.30$ (before Pixiv+Pixiv Fees), I will like to bump the tier up back to 5$ (around 800yen) but sadly Fanbox doesn't allow me to edit current Tiers, So to not make the story too long:
-I am making a new tier to go back to 5$
-I am deleting the current 600yen tier at the start of December
-Idk If your current subscriptions are going to be kept or cancelled
-10$ Tier is staying, will talk with Supporters in that tier to find a way to provide them extra material
