Kiana Kaslana and Mei Raiden want to try what a man feels like.
Kiana Kaslana is the Herrscher of Finality and is residing on the Moon in order to seal the Honkai Energy. She's been alone for years and has become sexually frustrated. Raiden Mei, Kiana's girlfriend, decides that she can release her frustrations with the captain of the Hyperion who was their mutual friend and was also visiting her soon. Kiana hesitatingly agrees, and plans to seduce the captain when he arrives. She however has no experience with men, so she's very awkward.
