PS: just to list some works I recall off my head.
- There was multi-page work where konosuba megumin blew her head off with a shotgun
- A multi-page work about 3 festival tribute girls and the princess volunteering for a snuff fertility festival
- Another multi-page work with a red headed girl I don't know cuts her head off while riding the protagonist
- Several multi-page works taking place in Entropy's "Executioners World" setting, about a city girl meeting a guy who say he will Execute her sometime so she lets the guy room with her and dates him till her Execution time.
- Several other one off multi page works in the same setting about different Executioner guys Executing a girl. the whole series was almost a "girl of the week" type thing
