My first 2girls in same frame test Lora. It allows you create these 2girls in one picture or you can generate them individually.

Characte Usami :

1girl,ensemble style,usami(ensemble),red eyes,short hair,blonde hair,single braid over shoulder,hair ribbon,hair flaps,white hair bow,

Characte Sumire :

ensemble style, sumire(ensemble),1girl,green eyes,black hair,long hair,purple flower hairpin,bangs,

2 in same frame:

2girls,multiple girls,ensemble style,sumire(ensemble),green eyes,black hair,long hair,purple flower hairpin,straight hair,

usami(ensemble),red eyes,short hair,blonde hair,single braid over shoulder,hair ribbon,hair flaps,bangs,white hair bow,

NOTE: Please use the correct order if you want to generate 2 of them in same frame correctly. you need start a new line then enter the other one's characteristic. Don't type them in the same line or they will pollute each other's characteristic.

Yet sometimes you still need to roll some pictures to the correct result.
