If volume one was short stories collection, here we follow one IS character from birth, to teenage years in later volumes. This one is more focused on the parent, who have given to the world a baby who is intersex, and now they are facing the choice of how to proceed with this situation and what would be the right decision for the future happiness of their child - to select a certain gender, have the operation and hide the truth in order to fit into this binar male/female community or accept the unique physique of their child and raise them as IS in order to give them control over their destiny.
I remember watching the tv- adaptation of the story. I want to rewatch it now. I cannot tell, how accurate is description of such bodytype, but I felt deeply for the main character Haru, who tried to navigate life in the best way possible and just wanted to be accepted as a human being and not to be judged because of their body.
I've got 5 volumes in now, and I like now the story goes and the art is beautiful. So on I go.
