The sequel has been uploaded, but although I say that, there's a different feel to the story. It starts after a thirteen to fourteen months time skip, where Alice is a second year student.
The first story is more of a way to force him/her to accept that he's in a different world. If the story was slower and the events didn't came like a machine gun, it would take the whole quarter to adapt and even after that he/she will have a mindset limiting his/her actions.
This tale has been pilfered from Royal Road. If found on Amazon, kindly file a report.
The second story focuses on Alice's life as a student on the first half and her adventure after graduation on the last half. Although I don't want to give spoilers, I think it's quite obvious based from the final chapter of this one that it won't be such a normal school and adventure life for her.
Sequel : I'm in a different world....but I don't mind
