エマ

"Are you all right? Would you like big sister here to explain it for you?"

An "*****" older sister-type girl, a bit of the meddlesome type. (To put it simply, a loli with big boobs.)

Her height gets pointed out often, but she's very feminine and is very capable of taking care of other people, so she does feel like an "*****" older sister. She also has a more maidenly, romantic side to her, but is still that "*****" older sister.

Be wary that she will get mad whenever you mention her height, or treat her like a kid. But the way she gets mad is also really cute, so sometimes you end up wanting to point it out just so see her expression.
