Sergio's route isn't affected by the questionnaire, so you'll get him every time if you keep choosing the same prologue choices. Only Vincent, Eira, Festus, and Allegra are affected by the questionnaire. Try writing your choices down the next time you do it, because if you flip to the opposite answers, you'll get a different character.
Could you give out another hint? I've tried out a bunch of different options on the questionnaire which leads to vincent, then i chose the opposite options which again just leads to vincent, here's the ones i could be bothered writing down
(1 = the top options, like agression, talk, copetitive. 2 = the bottom options)
Hello! Do you have the latest version of the walkthrough? You can download it here on itch or from our website: violetstudiogames.com
It has specific instructions on how to get routes that are tied to the questionnaire!
One thing to keep in mind is that Eira's prologue starts off the same way as Vincent - you'll still go to the bank and meet him, but he won't like you as much as he does on his own route. ;)
yeah, i looked through the guide and i thought Eira would want an MC that's compassionate, wants to listen, blunt, and whatever else seemed to "fit" her personality, but it ended up on vincent's route so i tried the opposite and it ended up on his route again (there's nothing unlocked in the memories for her). That's when i started writing down the choices, then i just started randomly choosing different options and it always ended up with vincent.
