Nupu Ryu, the developer of the adult doujin game 'Yariste Mesubuta', revealed on August 4 that Rakuten Bank refused to accept an overseas transfer of Steam sales revenue. The funds were to be sent by a Taiwanese publisher, 072 Project, to his Rakuten Bank account. The bank requested documents proving his relationship with the sender and the nature of the transaction. Even after he submitted contracts and answered questions, the deposit was refused, with the bank stating it could not disclose the reason. Nupu Ryu noted that he still faces tax obligations on the sales amount even though the money has not arrived. He plans to seek alternative banks or transfer methods and will report progress on his Ci-en page. 'Yariste Mesubuta' is an adult monster-raising RPG released in 2023 by his circle New Koubou, featuring over 150 monsters. It reached the top of DLsite's all-time doujin game sales ranking, and the Steam version, titled 'Yarimono', surpassed 200,000 copies sold as of July 2025. This is not the first such case; in April 2026, the developer of 'Shubunigurasu no Yoru' also had Steam revenue refused by Resona Bank.
Nupu Ryu held a live stream on YouTube on August 4, 2026, in which he explained that Steam offers better long-term sales than domestic doujin sites because of the global market. He also recounted an experience in 2025 when adult works he was involved in selling were removed from Steam without prior notice.
The Steam version of the game, titled Yarimono, is developed by New Koubou and published by Taiwanese publisher 072 Project and 072 News. It has gathered approximately 4,000 reviews on Steam with a "Very Positive" rating. The game features over 150 monsters called "Yarimon" that players collect and raise to battle trainers.
In July 2025, adult games were removed from Steam and itch.io and excluded from search results. Steam said the removals were due to violations of standards set by payment processors and related card companies and banks. The move led to protests from gamers overseas, who saw payment companies such as Visa and Mastercard as influencing whether expressive works could be sold.
Nupu Ryu said he will continue to disclose on Ci-en which banks he will use to receive overseas revenue and what kind of communications he has with them. The KAI-YOU article notes that based on publicly available information, it cannot be confirmed whether the transaction being related to adult games was the direct reason for the deposit refusal.
