My sister's pants / Asuka Hirose (Blu-ray disc)

My name is "Asuka" ... I do not want to go to school, but I really love schools! My parents are divorced... and I'm a very futo girl who lives with my older brother... "If you don't have that thing ... even that cocoon ..." because he works at the dispatch office, so his working hours are irregular, but he really does work hard to take care of me... But ... ... that cocoon ... I draw the love of my brother and sister, who are desperately enduring against his relentless play with an emotional touch.
