Ok, I have a perfect proposal for this.
Lets do a double lynch today then. First of, invisible votes for me. So 3 votes for me and trash. Both get lynched.
So the ones left are dsister, Final-Fan, nen and invisible. Over the night, the mafia kills someone. It will most likely be dsister, since he is 100% innocent.
So the next day, we have nen, FF and invisible left. And that day, my and trash's roles are going to be revealed; there are 2 possibilities and what it should be done after:
-trash turns out as mafia and I turn out innocent; in this situation, everyone votes nen-suer and we win
-I turn out as mafia and trash turns out innocent; in this situation, well vote for FF or invisible next day.
If you're townsfolk you should have no problems going along with this :)
