In the dark world, i let Jade (the green spirit) possess me because I wanted to see if I can get the Pi chart (in the party menu) to 100% jade, but i cannot get her to leave, since she 24/7 goes into fights where you do not have the option to struggle, and whenever she goes to the bridge or into her chateau, she stays there for one second and then immediatelly returns to fighting. When she stops fighting and the button to struggle actually appears, I cannot click it since in the exact same time, celica has to climax and the buttons availabilty disappears, so I am stuck in an endloss, non-ending loop for like 5 minutes now. Is it a bug/glitch, is it intendent, or am I just utterly unlucky?
Its intended to put it simply. If a character has the highest % in the Pi chart for Celica (especially if its more than Celica herself) they can end up having more control over Celica than you do. Its not permanent but it can become a challenge to regain control, especially if you gave that character some of the fox shrine spirit charms to have more power over Celica.
You can usually still escape and regain control, but for the characters you meet later into the game the tougher it tends to be. The rough thing with the dark world characters is that (pretty sure at least) you can't get kicked out of Celica's body. This tends to be the easier way to regain control, since there are guaranteed ways to regain control from that point.
So for Jade and other dark world characters, you just gotta get the timing right a few times in a row with struggling, and it can take a bit of time.
Edit to add: I've tried this for a few of the main world characters and since Violet is one of my fav interactions I got stuck with her in control for like 5 mins of combats too since she doesn't kick Celica out of her body. This was when i realized your situation can happen lol.
Look, the only one who banishes someone in the normal world and lets them return is Nell :) If that happened in the dark world with Celica alone, it would be more of a problem than a help. But that's about the main comment He said it's really annoying, you just have to wait and eventually it will appear, and there's nothing wrong with high PI, there's still no content for them.
well obviously it can't be 100% jade for a couple of reasons.
1. Nel has a minimum of 2 or 3 bars by the time you reach the dark world
2. Glace can have 2 permanent bars at some point during her quest line.
You are correct that escaping any of the 3 dark world spirits is quite difficult due to being unable to struggle during combat.
A relavent note is the timeout on struggling is a real time lockout from being unable to attempt again so if you skip through the lewd action in non combat scenes you will likely end up back in combat before you can struggle again i think.
