Twin cosmic wraiths carrying space whales on their backs. The younger sister. She has dark skin is a shy loli. Her older sister Aqua has white skin and is a mischievous loli.

Since cosmic wraith males have become extinct, the two of them are always flirting and being naughty with each other.

Because they have been honing their techniques together on a regular basis, they are skilled at giving pleasure. Perhaps because they are whales, they squirt quite easily. Their fluids have an effect that excites males, and the pleasure greatly amplifies.
