FIRST IMPRESSION
This is obviously my personal opinion but i feel like you can have a shared universe , let's call it "Lust Academy universe" with different protagonists.
And for the people that have given up on Lust Academy for various reasons ( i am included on those people) , i think it would make more sense if the protagonist of this one , wasn't Mr. I Am Going to Fuck Everyone in the Academy and instead was a brand new protagonist in this world of magic.
I talk for myself , but having the same protagonist as someone not interested in finishing Lust Academy , already makes me feel disconnected with the protagonist himself , which is not a good start for me.
I think this story could benefit more from having a new protagonist , you can keep the "woke up from a coma " plot , you could keep the amnesia plot from the beginning too. But it would give you more opportunities to explore his backstory , you could with a new protagonist , do some flashbacks where he remembers memories from his past and present his past story and how he became in a coma like that.
It would give new readers the ability to be able to follow and connect to the protagonist and to readers that gave up of Lust Academy , the ability to relate and connect with the protagonist.
Because the people that didn't enjoy Lust Academy protagonist will be disconnected from this game right from the start , the new people will feel disconnected from this game because there is a whole backstory from a previous game they have not played and probably have no intention of playing , and the players that have indeed finish the full Lust Academy story while they will feel connected to the protagonist , they will some of them find weird why none of the old characters where the ones waiting for the protagonist to for example leave the hospital.
Personally , and i know this is a lot of work , i think this story would benefit from a new protagonist who let's say in a case eventually can meet the Lust Academy protagonist.
