Akito Niitsu specializes in retraining difficult cases as a social worker. He accepts a contract from a maid school to transform four failing students into acceptable members of society. His mission requires educating these problematic individuals in professional domestic duties and erotic services to ensure their graduation despite their shortcomings. The students comprise a destructive bodyguard, a hopelessly clumsy maid, one accompanied by younger sister maids, and another struggling to maintain order.

Operating within a maid-training academy, Niitsu adheres strictly to the institution's instructional guidelines. Throughout the one-year training period, he manages the students' chaotic behavior while striving to preserve his own sanity. His methods emphasize discipline and comprehensive reeducation to salvage the students' futures.
