Choukadou Girl ⅙

The same harem, in small packages and the same amount of trouble for the guy also in small packages.  

Both have the same situation where guy get to have a girl that was basically the size of a small doll and the same harem genre where the harem member were in small packages...literally. 

Both feature a main girl that loves MC and do whatever he wants and also both of girls are supernatural creatures. And also as the story progresses both of them have small harems... 

They’re both about living anime girl figures. They both have a blend of 2d and 3d animation.  

Both anime are catering towards otaku who enjoy collecting scale figures, and feature a similar premise surrounding a miniature girl character and the antics that ensue. There are nods towards otaku culture and some more meta elements of figure collecting are acknowledged, though it's less pronounced in Hand Maid May since May is not technically a scale figure. Both series' approach comedy in a similar way so expect some meta-comedy, slapstick and absurdist humor all around. If you like anime figures and consider yourself an otaku, you might like what either series has to offer.
