I'm really happy you enjoyed the game! I'll do my best to proceed translation to let you enjoy more!
And I thank you for that! I did hope that Yudai could top more though, especially with Fujiyasu and 忠右衛門 since they are both my type ;) I look forward to more player top content in your next project!)
Also, a small request and I hope it's not too late. Could you please add all the reports (報告) to the memory lounge (回想部屋)? I think those reports are pretty hot and well-written, and they should be available for review (except the parts that involve SC*T. There should be a warning if those are included)
Could you try again? Fisrt of all it has to be a card in your local country that supports international payment, so it cannot be a debt card or a credit card that only allows local transactions. Additionally, since in my case my Booth was linked to my Pixiv account, my card had to pass on Pixiv first. My first time trying to register my card on Pixiv actually got my account restricted, but after I contacted them to unban me my card also started working.
