Young Satomi Ryo works as a CSW (Community Service Worker) for her local Social Welfare Agency. Her job is to seek out those in her community who are calling out for help for the problems they face but who aren't able to make themselves known. Along with the rookie Miwa Minaka at her side, she'll help out anyone in trouble right to the end, even if it means battling her own Agency to do so. But Ryo's reason for not letting go of the hand she holds out to those silent poor may be due to a secret from her past.
