Well, I had a feeling if I read through eight chapters of this, I would find one half-decent one. Finally found it at number eight. Unfortunately, it's only half-decent. But an FL with actual agency was a breath of fresh air.
Agree with the rest, this story did not need a second regressor (which is what these are, not reincarnators. They have the same bodies as the first time around, so they are not 'reincarnated'.) His part in this, without any hints of regression, would have been better.
That, and rewritten as an actual series (maybe a short two or three volume one) would be even better. This chapter had the potential for that.
