The 4th costume of Phase Connect's Kaneko Lumi, as seen in post #7439657.
A space-themed costume, she now wears a long-sleeved white jacket worn over a black leotard with an underboob cutout, white pants, and white boots. Rather peculiarly, she has an option to remove all the inner garments except a black pasties covering her nipples with this costume.
