Chuugakusei (Kari)

When a little sister tries to act adult, that's annoying enough. However, when she keeps bugging her older brother about wearing a sailor uniform (even though she just has to wait two years, after which it will become her school uniform), even to the point of wishing she had an older sister instead of older brother, said older brother may just fulfill her wish. After all, he does have a sailor uniform, except it's a fetishwear that is actually transparent.
