(Unrelated) Which of these girls is most suitable to be main heroine in jrpg??

i want to make this poll on twitter since it's an unserious side project,but twitter poll is functionally broken so i made it here

this was meant to be a future/experimental project about a harem fantasy rpg, which you can romance one from all of these girls and have them have netorase once you become their lover

you can choose one of the girls as your romance no matter the poll results,but if there was canon storyline, who will be the main heroine in the canon story

the character:

-purple hair,ekaterina,shy,timid,gentle ,book smart,a librarian of some sort

-blonde hair,samanta, air head, genki, friendly, clown, a rookie adventurer or some sort

-black hair,anna-lisa, tsundere, scary, short tempered, antagonistic, some kind of elite soldier

-red hair,thaleia, mature, nurturing, milf, easy going, some kind of inn keeper
