If the scene starts as fully yuri, but eventually a male comes in and joins them. (The “Male Involved” tag is only used if the male is involved from the beginning of the scene.)
All 4 girls introduced are shown to have a sexual relationship and split off into pairs to have lesbian sex with each other in different rooms.
Content Warning After Page 6, the male antagonist shows up and then begins to rape and kill the women. So I’ll be tagging this with Male Joins and Gore as warning tags.
The group go on a trip to visit Clammish’s cousin, Offira, where during dinner time, Offira asks the MC if she can borrrow Clammish for the night to “chat.”
Once alone, Offira gets right to seducing and having lesbian sex with Clammish.
Eventually the MC and another man join them for a foursome.
While the MC is having sex with all of the girls, Miyako presents Chris to him where Chris admits she came from Miyako eating her out and fingering her off-screen.
Miyako then asks to have sex with him next, but Chris also wants to, so they both have lesbian sex with each other as a competition to see who can have sex with him first.
At the start of the chapter, Malida began to have sex with the MC, Irena and Lichere a lot more off-screen as her bloodlust for the upcoming battle also increased her arousal. (This is very inconsequential, so I didn’t tag for this part, I just wanted to mention it.)
After the battle, we are introduced to Liese, which upon finding out she’s basically a tomboy, we get these lines from Malida:
“Albert, a girl, who crossdressed as a guy, might be nice as well. I like girls, but women like Liese are my guilty pleasure. She gets me all riled up. I think it’d be nice to get a taste of her.”
Malida then drags Liese off to the bedroom where they have lesbian sex with each other several times off-screen, but we do hear them moaning.
Eventually, Irena and Lichere join them as well and there’s a short yuri foursome while the MC watches.
This is also the first time any of the girls kiss each other on-screen. It’s possible it has happened off-screen before, but it’s never mentioned.
After a while, the MC joins and remains involved for the rest of the scene
At the start of the series, the MC’s fiancé, Kanae, supposedly runs away after finding out the the MC wrote erotica.
The MC has a dream about Hitomi NTR’ing him and tells him that she has been having lesbian sex with Kanae off-screen throughout the whole series.
After he wakes up, he goes to confront Hitomi, which eventually leads to the reveal that Kanae was actually there and it’s strongly implied that his dream was true.
At the end of the chapter, there is another reveal with this is purgatory and that the MC is in a coma, so regardless, the entire story is an Imagination.
The MC catches 2 random girls nude together (possibly having lesbian sex?), causing him to run away, but then he imagines having a threesome with them.
