P.S. any other good games you can recommend?
Last year in a Q&A, Toro said he wanted to do a game about Red hood and another about the demon princesses before doing bs 3. After finishing dlc 3, I think he started working on his touhou game? as well as catching up on games he ignored to finish to the dlc. Can't say if those are still his plans now or not.
I can generally recommend the Sequel series by Hakika. Sequel Blight, Sequel Awake, Sequel Colony and soon, Sequel Kludge. There is also a spinoff called Asylum. Additionally if you enjoyed the gameplay in those, one of his previous non h games is also translated. It's called Liberty Step. These are all traditional turn based rpgs with a good amount of playtime (20-30 hours each, more if you do all the post game). Some systems vary between them so they are all unique in some way.
If you want more Grimm, there is Lust Grimm. Not as heavy on the fairy tale stuff as BS but it's there. There is also a sequel called Lust Friend but its themes and story have basically nothing to do with the previous game. There is a heavy emphasis on the downward spiral from losing in Lust Grimm. Lust Friend is much more easy going
unless you do the hidden genocide route. It requires a lot of grinding though so I didn't bother with that route.
For more rape them into love, The Dungeon of Lulu Farea and its sequel Demonic nation Florehades. Both are more of a puzzle game than an rpg though but I recommend giving them a shot even if you don't like puzzle games. There are cheat rooms in both if you are struggling though.
Finally, if you want something just completely different, try Attack it! Devil Legion. You build a team of AI controlled monster girls and guide them to attack enemies. Be warned though, it can get really frustratingly hard on some of the later stages.
