A shithead family breaks into an old lady's garden and makes a nest. Old lady, due to her age, decides to ignore them for the time being and lets them stay. Dipshit yukkuris believe that they "defeated" the human and act like they now own the place. After they damage the garden and make a mess, old lady calls upon her granddaughter for help... who is coincidentally happens to be the big-tiddy fem-anon from other boshi stories.
Hilarity (not for yukkuris) ensues.
