Here is the not so sure fan guide for corruption
Some characters doesn't have corruption yet, therefore i will list all the characters name on this guide but leave empty space for those who doesn't have corruption yet. And update it when available.
First, What is corruption?
- visit the seal in the game, it has a explanation there aswell..
- there are currently 2 level of corruption.
- Corruption is made when you do something sus with the characters, there is 1st corruption and, 2nd corruption.
- 1 sus = 1 lust.
- you need atlease 1 lust on the character to activate corruption.
- For first corruption event, you need 1-4 lust on the character and you will unlocked the 1st corruption scene already;
- while for the second corruption event you need to reach 5 lust for you to be able to unlock the scene.
- lust is displayed in the love status window.
- This apply to all characters!
Lastly, corruption is NOT a MUST! to progress on the story, It is a player choice! There is always a choices to continue or avoid the scenes.

i personally think that corruption event is like a rewarding easter egg that each of us can find, but, if you find it hard to discover, or you are just here for the business ( ͡° ͜ʖ ͡°) you are in luck! or not because there might be wrong on this guide!, so if there was, please reply on this comment and correct that wrong statement that i had listed and i will use that to update this guide because its kinda tiring to reply to the same questions time to time (i made this solely for this reason and I know its not my job but ive done it already, so what are you gonna do!? cry?).
I don't know if anyone made a guide for corruption before, but feel free to copy and paste the main guide. And of course! unusualfish can use this and do everything he wants because he's the goat.
