Secrecy
Standing on your roof, you're certain that the nearby mountain is shrouded in secrecy. But you can't do much about it, stuck on your roof as you are. So much secrecy, but so far away.
Really feel the frustration of wanting to uncover all the secrecy around this mountain but being stuck on your stupid roof.

This secrecy is so secret that the people who know about it wear magical mitts (みつ) of secrecy that make it so we can't tell anyone, no matter what.
You can imagine trying to break one of the mitts-wearing members of this group, but they can't tell you anything because of their magical mitts.
