As expected from Oshimi Shuuzo, Kusakabe-san offers a look inside the dysfunctional relationship between a disturbed man and woman.

Our introduction to Kusakuba is a strong one; laid out in front of the nameless protagonist's apartment with proclaiming she had just been raped with a carefree grin on her face. This is probably one of the more subtle bouts of insanity displayed in an Oshimi manga. The two waste no time in starting a sexual relationship before they actually begin dating. It's also implied Kusakabe has an eating disorder due to her alternating between not eating and then binging followed by purging.

Kusakabe is a complete enigma. We don't know why she does what she does or what her backstory is. It's probably better than way. There's no reason to explain her insanity because her worldview only makes sense to her. The protagonist isn't much better as he feels worthless without her and doesn't besides yell when Kusakabe brags about how many men fucked/raped her and how it was better than the sex they had. These two are hot messes who probably only have each other to confide in.

The short length of this one-shot is its biggest hindrance as there isn't much room for character development to make the pairing feel alive. We only know the bare bones of who they are and can only speculate what in life led to where they are. If nothing else, this manga shows that even two losers in life can find true love.
