Here’s the thing I’ve decided about how the party’s gonna work.
In most runs, you’re gonna have 4 party members,
Those being Your Main character, Kira, Siren, and a character you’ve yet to even get close to meeting, Nauka the scientist Dog, who’s been planned for a long while now.

However, I’m changing one thing for certain.
Kira does get fed up with the killing on a genocide route, causing her to get leave, and get killed off if you reach THE POINT OF NO RETURN.
…At which point you’ll receive a new party member, the power hungry Jackson.

And I decided to go back to not only my original plan of restricting Jessie out of Pacifist, but restricting her to only genocide too.

So your party make up will look completely different in pacifist/Netural and Genocide.

Which will be Main Character, Jackson, and Jessie.

However, for the game’s finale, you will have access to everyone for story reasons.

Also, thanks to my IRL friend, no, Kira’s perfectly fine, her personality does not need to be fixed, though she’s getting a bit of a redesign due to it, in my opinion, being a little old and outdated with my vision.
