Anny longs for her twin sister Agatha, whose departure left an irreplaceable void in her heart. Despite her efforts to find joy in everyday life, a sense of monotony permeates her existence. Anny finds comfort in the whimsical companionship of Mona, her mischievous Bitsyeti best friend. Together, they try to enjoy (or rather, endure) their mundane existence.
In a twist of fate, Anny meets Denny, a mercenary who recently encountered her adventuring twin sister. Denny is a long-winded klutz, but is there more to him than meets the eye? When he asks for a very strange favor, Anny is convinced to assist, and her curiosity propels her into an extraordinary adventure.
