Okay so the boxes below show you the party you begin the prologue with and then the second box shows your main party for PSV. Characters with red dots beside them are considered hidden and can only be obtained by fullfilling certain conditions.
I've changed Jona's sprite and Im still not happy with his Party 1 version so I'll revise that.
The characters you see in party 1 are as follows:
Jess:
A keen researcher studying the Bio-Monster phenomena.
She boards the Alisa III along with her father Doen.
Jona:
A highly skilled apprentice to the Order.
He was bought up in the slums of Motovia untill his talent was spotted by Rem.
Iris:
A soilder for the order.
She is constantly in competition with Rem for the top spot in the military.
Jona and Her have had "history" together but that doesn't stop her from acting professional.
Rem:
Lead Soilder of the Order.
Only a few are giving this honour due to their excellent fighting skills.
Rem considers Jona as his successor.
Karn:
Captain of the Space police.
He has robotic implants that allow quick access to the Orders commands.
Thats the information about the Alisa III boarding crew so far.
As always expect changes.
