It's fairly obvious from schezo's role that he performed the N1 nightkill. Saying other people might have done so is pretty pointless; and saying people have not done so it equally pointless.
A reminder of Schezo's role:
Alice Murgatroyd. Seven Color Puppeteer.
[REDACTED]
Alignment color - Red.
Night Abilities.
1. (-). Invisible Wire ~ Be the Puppet. You control one of the players during the night. They perform their night action on the player of your choosing.
2. (+). Hanged Hourai Dolls. You protect your group with 1 time bulletproof protection for the duration of the night. You can not use this ability for the next two nights after the successful use.
Passive Abilities.
1. (+). Little Legion. You're master puppeteer and your dolls do all the work for you. Because of this, your nightkills are untraceable.2. (?) An Unlikely Alliance. You share a common goal and can talk with your team.
Win condition.
You win, when everyone other than the members of your team is dead, or when there is nothing that could prevent that from happening.
Bolded is the part which basically says Schezo did the N1 nightkill. Especially since it's passive. Invisible Wire seems silly to use with no information and the same with Hanged with the 2 turn cooldown and no information.
##Vote: Polaris.
I died last night. Of course, I'm a fairy, so I respawned.
Wait what.
