Belphegor has Sade and Kaloris join in on having lesbian sex and corrupting the Sister.
The volume ends with Michael hearing them and walking towards the door. Possibly he’ll join in Vol. 2, or maybe they’ll detour him away so we can get the current scene in the fanbox. I guess we won’t find out for a while.

Before attempting to kill Chika, Kachua gropes and rapes her while she’s tied-up in a trap.
Eventually Chika gets free and ends the scene.
Gore Warning?
Kachua uses the bladed edge of a knife as a pseudo-dildo on Chika, but there’s no blood. Just a word of warning I guess.

Sade and Kaloris are shown licking and groping Belphegor during her birthday party.
This was the first fanbox extra to not have the “Lost Paradise” title, so this is probably canon and not a part of Rosetta’s doujin.

The FMC saw a horror movie earlier and gets scared while taking a shower, so she tries to imagine erotic thoughts.
We then see a female ghost trying to sneak up on the FMC, but as she gets close, the FMC’s erotic thoughts take form as a succubus and has lesbian sex with the ghost.
The chapter ends with the ghost running away and the FMC being completely unaware of what happened.
