Well, my little sister can't be that cute. Volume 2

Kyosuke Kosaka learned that his younger sister Kirino is a hardcore otaku. This unexpectedly revealed secret brought the brother and sister closer together, who had long been on rather cold terms, and Kyosuke even helped his sister meet a company of others like her, teenage otakus. Kirino finally had friends who shared her interests, and it seemed that everything couldn't be better, - but then her father finds out about her hobby, who is categorically against anime and manga. How will Kyosuke behave as a witness to the heated quarrel between his sister and father?
