Agreed 100%! A much better example is Hakaui no Shihaisha. Still no safe words but much much better in terms of consent and safety.

Please don't ever start a BDSM relationship like this manga. >.< ( I did enjoy it because it's fiction. Please don't accidentally confuse that kids.)

that wasn’t even considered consent

This manga made it seem like it is trying to be realistic, and there was dubious consent.
In the other rape mangas, the scenario seems very fictional, while this one used explanation, toys and talk about consent (where there was none). So I find this one worse.
Not gonna say I didn't enjoy it, I fapped to it hard js
WTF! That first comment was misleading af! You never invite a a DRUNK WASTED person into BDSM , especially one that has never done it before, and that is a terrible way to do it with a begginer, no limits were discissed, no safe words, what the actual fuck.
