Also how would they story change?

Scenario 1: only emilia is darkmilia

Scenario 2: satella is dark elf too so in verse emilia is identical to satella

U degens can role play in the comments

It would be funny to see subaru fall for aqua(who's present in the Tower for some reason) in arc 6 after >! losing his memories.!<

Tappei has stated subaru would had fallen for aqua if subaru was konosuba' protagonist.

Also would be quite funny to see bumilia camp reaction to it.
