There are definitely scenes of sex, but also a reminder to those who do not know, there is ryona in this too. I found out while playing it, randomly lost after a swarm of zombies got me, then one of the girls (the otaku girl) was brutally murdered in a weird sex scene/death scene twist.
I saw a sex scene with the guy who has a guitar, so the intimate events are there, and of course, you sex them to heal them.
But then again, I am playing "Sweet Home" version. I assume everyone by now is playing that version as well.
I actually don't like the grinding, but the game is fun. I downloaded the full save, but I have my own save separate, so I will probably go back to my own to continue it.
