Size-Size-Kun!!! (Patreon)

Lala's new invention Size-Size-Kun followed her to the school causing al kind of problems, like it usually happens with her inventions.   Right when Yui and Lala had Size-Size -Kun under control one the famous Rito's falls made the little robot to activate at maxmun its size changing powers

Lala and Yui were the most voted characters on the multiplatform poll that made them the victims of Size-Size-Kun's effects. 

Yami obtained a second place on the patreon poll and i'm thinking that deserves her own moment to shine too.
