Hetare Ane.

This is a 4-koma about the height difference between 146-cm Mana Shinomura, a warm and ditzy older sister, and 187-cm Eitarou Shinomura, her inveterate siscon younger brother. At home with just the two of them, Eitarou lets the siscon feelings burning in his chest run wild. At school, their various friends join in, making it lively. Those who like small older sisters acting like "big" sisters, height differences, or slapstick comedy should definitely take a peek.
