You keep pumping out those isekai profiles, i gotta up my game lol.
Anyway Mile should be building level with lightning attacks since it's real lightning.
She should also have low mid regen:
For a short time now, she hadn’t moved at all. The nanomachines had heard Mile’s unconscious cry of distress and were currently in the process of performing an emergency healing, but it would take a bit more time before she was able to move.
If her bones had been merely broken, the healing would have been incredibly fast, perhaps even instantaneous. However, bone fragments had torn her muscles and organs to shreds so repairing her would take that much longer.
Well, there are two isekais called Otome Game, one of them will have anime next year, but its MC is female and is the villain of an otome.
My favorite is Otome Game Sekai wa Mob, well, it's a novel where the MC played an otome because his imouto forced him, and after he died, he reincarnated in that same otome as a mob or secondary character.
The really good thing is the personality of the MC, his actions seem that of an antagonist and good, I loved that novel. It has slice of life with some comedy and fantasy.
