When SFW game series getting their official NSFW sequels, spin-offs, installments or collabs with NSFW games

For the context:
1. Mikagura Shoujo Tanteidan (御神楽少女探偵団) is an SFW detective game series by Human Entertainment (a bankrupt Japanese game company who also created Clock Tower horror game series). The series consists of : Mikagura Shoujo Tanteidan, Zoku Mikagura Shoujo Tanteidan and Shin Mikagura Shoujo Tanteidan. Human Entertainment went bankrupt after releasing the first two games and last one is made by a game company named Nude Maker (which has a few former Human Entertainment staff workers in it) and it’s the only game of the series which is the official sequel for it but NSFW.

2. Valis (ヴァリス) is another SFW urban fantasy horizontal action game by Telenet Japan about the heroine fighting demons, and it’s released in PC-88, PC-Engine (a.k.a TurboGrafx), etc.. The actual final installment is Valis IV (four) released for PC-Engine in 1991. The last "pseudo-official" installment Valix X (Cross) was released when the rights to the "Valis" series were sold by Telenet Japan due to financial difficulties, and that version was developed by EAntz, an adult game maker that newly acquired the rights.
The game changed the genre from action to adventure, and was an adult game with an unusual and unusual amount of Ryona depictions. (Ryona is an (usually) R-18 "fetish" genre depicting boys or girls getting abused in a sexual way)

3. Asuka 120% (あすか120%) is another SFW all-female fighting game developed by Fill-in-Cafe (later Success Corporation after Fill-in-Cafe went bankrupt) and published by FamilySoft. It is set in a school where members of school clubs fight each other in a fighting tournament. Originally released on the FM Towns home personal computer in 1994, it was released for multiple systems through the years.
In April 2022, there’s a sudden announcement from the not-famous dark fantasy web game called Eden's Ritter Glenze (エデンズリッターグレンツェ), which will collaborate with Asuka 120%. Considering Eden's Ritter has an alternate NSFW/R-18 version, they confirmed that a few heroines of Asuka 120% will have their own NSFW Ryona scenes in Eden's Ritter Glenze. Unsurprisingly, it became a controversy among Japanese Twitter users.
