During his tenure as an assistant for a group of adventurers, the individual known as ■■■■■ was deceived by his fellow party members while exploring the Mt. Kuguse, a perilous terrain infested with dragons. After sustaining serious injuries, ■■■■■ later wakes up in the nest of the Red Dragon, Kafal, who lost its offspring during the previous tragedy. Due to memory loss, ■■■■■ now goes by the name Lushela and has transformed into a female. Kafal subsequently takes on the role of a foster parent for Lushela. This is an unusual account of how the peculiar destinies of one dragon and one human lead them to develop a unique parent-child bond.
