Just when you thought things couldn't get weirder.
- We've had a girl with her heart cut out.
- A girl who took a picture who then fell out of a random door in an awkard and lulz fashion
- 3 girls investigating door girl who all somehow got speared in the head
- Random couple we've never seen before being all lovely dovey and rapidly raising their death flags
- Direct view of the "Tower of Mysterion", which literally just looks like a phone tower
- Weirdo occult girl who gets Ahegao face over talking about the occult
