Multiverse Academy with a Naughty System

The main characters I will focus on at the beginning of the story:

- Naruse Mio (Shinmai Maou)

- Moka Akashiya (from Rosario + Vampire)

- Vermeil (from Kinsou no Vermeil)

- Rias Gremory (from DxD)

- Makima (from Chainsaw Man)

Characters I plan to add later:

- Fern (Frieren)

- Esdeath (Akame ga Kill)

- Shion (Tensura)

- Mimosa (Black Clover)

Main Kingdoms of History:

- Clover Kingdom

- Tensura Kingdom

- Kingdom of Belzerg (where the Multiversal Academy is located)

The structure of the world is mainly magical.

I know that many of the series mentioned above have modern elements, but this will need to be adapted. I hope you understand.

I'm open to suggestions and criticism, so you can comment on characters you want to see and also use the comments area, but please be polite ^^
