Princess X – My Fiancee is a Monster Girl Walkthrough (JAST USA)

Princess X pre-order

This is a walkthrough for the Princess X monster girl visual novel by Poison@Berry, localized by JAST USA. The full original Japanese title is “Princess X ~Boku no Iinazuke wa Monsterkko!?~”.

In this walkthrough you’ll find the right choices for all 4 heroines and at least 11 routes. You’ll naturally also unlock all CGs as you go. Keep in mind that you’ll need 8 save slots as well.

This guide is entirely based upon this original walkthrough by 2dfan. Only instead adjusted to match the English translation instead. So all credit to them.
