Very good adaptation. The plot tells us about the relationship of a brother and sister, where the sister plays an important role.
I think that the score is 7 very low. The viewers are not fully imbued with that atmsofer, which shows us the author. Each scene reveals the characters' characters. Most importantly, they do not just stand still, but they also change for the better. This title is a golden classic, which I value with all my heart. Very, very sorry that there will not be a second series ... But even so, this OVA is the best that was this year.
Drawing and animation 10/10.
