There are many girls in the world who run away from home for trivial reasons. When they can no longer bear the hunger or when they need shelter from the elements, they easily accept the invitations of strangers. Yuzu-chan, who ran away from home after fighting with her mother, is one such girl, but while she was running away from home, she fell into the clutches of a lolicon old man who happened to meet her and used her body as a toy. This is the survival technique of a runaway girl who bravely survives in these harsh times.
