A female lolicon? Yes! Misha is a child, whose mother has passed away and lives with her father. Tsubame Kamoi is a female lolicon and former JSDF member, who just wants a job where she can have a cute little white girl wear the clothes she made. This plot (minus the lolicon factor) has been in several movies (maid comes to help out, kids try to run her off, fall in love in the end). The lolicon factor makes this comedy stand out and definitely is worth the watch.
Uchi no Maid ga Uzasugiru!
