Let's guess
1st, does it have anything to do with the statue in the portal of room 201?
2nd, Yippee kasumi will be site assistant.
3rd, The doll that can turn into a Masuo?
1.Nope! I hope you will find this one out.
2.Yeah, but you will need to do some things to be able to recruit her or she is gone.
3.Yes, if you are able to find where Ryoko have been hiding that puppet.
Let's take a wild guess the looked rooms in mei house :)
That's not it either.
