Japanese adult manga circles 山雲 and 愛・筋肉博 release new titles, warn of illegal download risks

The Japanese doujin circle 山雲 released the 48‑page adult manga "SEXをすればえらいようなお屋敷" on 18 June 2026, while the circle 愛・筋肉博 issued the 117‑page work "キモおじ⇔JK入れ替わり【4】ホームレス輪●地獄" around the same date. Both titles are marketed through the legal platform FANZA, which offers discounts, coupons and a subscription reading plan that can include the works at no cost during a trial period.

The promotional texts also stress the legal and security hazards of seeking the manga on unauthorized sites such as "hitomi" or "hentai raw." They note that downloading from such sources can breach Japanese copyright law (penalties up to two years imprisonment or ¥2 million fine) and expose users to malware, personal‑data theft, and fraudulent advertising. Readers are advised to use official services to avoid these risks.
