While on a job, Dale -- a young but accomplished adventurer -- comes across a little demon girl all alone in the forest. Dale can't bear to leave her there to die, so instead, he takes her home! Demon or not, Latina is beyond adorable and it is not long before he finds himself head over heels with being her guardian. Can Dale handle the trials and tribulations of childcare and being an adventurer?
