I fail to see why it matters that he's the 'hanako of the toilet'. Most of the scene don't even have anything to do with the toilet. He could be the Bethoven of the music room or Ninomiya Kinjiro statue for F sake it still do not affect the story whatsoever. His weapon of choice don't even related to toilet. Just imagine a boy in bethoven clothing wielding a knive fighting evil spirit, the story do not change much even if you change hanako with bethoven. Even when his past is revealed, there's really no strong connection of him being hanako. Considering he want to be a teacher, making him become a kinjiro statue would make a lot more sense IMO. This setting is really pointless.
The messy art do not help with the storytelling as it convey more comedic (ironically most of the jokes are not even funny) and romance tone than horror ambience. I enjoy seven school mysteries tropes since I was in grade school, the horror in part is always the main appeal even when it appeared in action or adventure manga. IMO, this series is a proof that using romance in seven school mysteries setting is a huge fail.
I just can no longer justify myself to read this any further after 3 volume. To put it simply it's just not for me.
