The official swimsuit worn by hololive members for the Hololive Summer 2023 event "Splash Party".
This time, they invited the public to submit swimsuit designs as part of "Hololive Creator Contest 2023," and Naka's design (pixiv #105325141) was chosen. It is a layered bikini consisting of a color-coded striped bikini with a front-tie bikini top and a highleg bottom, worn under a white bikini with blue straps and either dark blue/black shorts or a blue bikini skirt, both of them with a color-coded overskirt and small waist bow, a color-coded thigh strap and toeless boots.
