Thanks to MGD's creators and artists !
All girls have good parts, so I wrote a lot about them.
My favorites are Mizuko & Himika, Amy and Kotone.
The Oni sisters Mizuko and Himika are funny. When you work at the brothel and interact with them in random events, the story follow up when you find them in their den.
Amy is playful and cute. Too bad there is not much content with her.
Kotone best background story. Hoping to have a story with Tabitha since Kotone was looking for another woman to experiment hypnosis on MC (and maybe the Lumiren). Or with Kotone's best friend, Feng.
Kaia, Jora, Kyra, Trisha and Ancilla are nice too.
The Tengu and Matango do not have much content, but they are great too. More content with the Salaris could be fun with their paralytic venom.
Hoping there will be new content with Mimi (alias bed-chan) and Aiko.
Some training with Shizu would be fun like with Beris. Maybe include Galvi in the training.
MC dominates Camilla would be fun too (or Camilla training MC). Also hoping more content with her will come.
Amber seems a bird of the same feather, it would be fun to have events with her like spying, wingman, ...
And many more amazing girls.
It would be interesting to see Goblins (rivalry with Elf and Imp could be fun), Tigers (or feline), more eldritch or alien like Amy (created by Nihltet) as sennoden already proposed, Fallen Angel, Elemental (but already Nova and Bubble slime), Giant, Centaur, Hydra, Lamia (but already Jora), Merfolks (but already some in mods), ...
More events and content at the brothel would be fun too.
