The 7 mysteries were in a strange room where in the middle there was a table with a button.

Akane: great, now where did they put us?

Yako san: What is all this?

mitsuba: a-ah? This place is very closed

shijima mei: uhm? This is not my art room

tsuchigomori: lord 7 do you have anything to do with this?

shinigami: doesn't say anything.

hanako kun: don't look at me, I was just playing cards.
