rikaisha
Rikaisha is the third single by 22/7, as well as the costume associated with it.
The costume consists of a grey vertical-striped white collared short-sleeved dress, a dark blue (almost black in appearance) neck ribbon, dark grey (almost black) kneehighs (or black pantyhose), and black loafers. An emblem of 22/7 is sewn onto the left shoulder of dress. Decorative buttons adorn the center of the dress, which does not have a functional front opening.
