Can you guys please help me find this one?

My list is gone and I marinated this for so long and now I want to read it again.

It’s similar to the “emperor and the female knight” the difference is the fl is black haired and she actually got reincarnated to a ?knight?? who survived an explosion since I remember they were in the middle of the war, and she’s the only survivor when she died in the modern world (she is part of a military i think that’s why she’s good at fighting) Her name i think started with? Karin karis?? i dont remember

Pleasee help me
