スプラ

A cute girl who is idolized by certain dark elves. Since she is also clever and aware of her cuteness, she uses it to pull pranks of all sorts. Truly a little devil of a girl. She thinks of her brother as something of a pet or a toy, but to surpass her sisters, she tries most proactively to become pregnant with Ober’s child. Yet, Ober is able to toy with her in turn, thanks to his pushy attitude and Supra’s lack of knowledge about the sexes. [From MangaGamer]
