相原 夏美

Natsumi is Takuya's spiteful step-sister. She has a very demanding and haughty type of personality and she often abuses Takuya. She works at a company and shouldn't be at home at all but since she is on her vacation time at the moment - she came back home just in time to find out that Takuya has transformed into a girl again, the event all too familiar to her since last year. Unlucky Takuya will have to survive her abuse once again.
