That one's probably on par with the anime department episode for me - while the topics don't go as extreme as a dad perving on his daughter or trying to justify doing horrible things by delusional comparison to a manga he likes ('Call me daddy'
), I think the unsettling part of the anime episode comes from how frantic and rapid the cuts between the flashbacks and present time get, and I personally found the production falling to bits very creepy.
To be honest, when one of the BREATHER episodes is when a trio of friends meet up to commit suicide, you know you're in for a disturbing show.
