After spending the last two volumes trying to keep her head down and ignore all the spirits and demons around her, a new substitute teacher brings something evil right into Miko Yotsuya's classroom, finally forcing her to reconsider passivity and experiment with being proactive.

And before all that, there is a fun visit to a haunted house of the amusement variety that proves quite cathartic and a spirit attack that actually surprised me for the first time in this series.

It's great to see some of the potential in this premise finally coming to fruition. ( )
